This week’s On The Radio segment discusses Good Neighbor Iowa, a statewide campaign attempting to reduce the use of lawn pesticides in Iowa.

https://iowaenvironmentalfocus.files.wordpress.com/2017/05/good-neighbor-iowa.mp3

Transcript: Good Neighbor Iowa, a statewide public education campaign to reduce children’s exposure to lawn pesticides was recently launched.

This is the Iowa Environmental Focus.

The Good Neighbor Iowa campaign involves school districts, park managers, childcare centers, and community leaders who are demonstrating that it is possible and practical to manage large areas of turf without the use of pesticides including herbicides and insecticides.

Ultimately, their goal is to transform Iowa’s culture so that we appreciate diverse lawns as a way to protect children’s’ health, water quality, and biodiversity.

The entire initiative and the website were researched and developed by students at the University of Northern Iowa in the Interactive Digital Studies Practicum class taught by Professor Bettina Fabos.

The website contains a map that highlights schools, parks, childcare centers, and institutions in Iowa that have pledged to manage their lawns without the use of pesticides.

The website also contains tips on managing a healthy lawn and a blog discussing the effects of lawn pesticides.

The spring semester has come to a close and most UI professors have retreated to their campus labs to catch up on research. Dr. David Peate, on the other hand, is spending his summer days floating on the South China Sea.

This is no pleasure cruise, however. The professor of Earth and Environmental sciences is working 12-hour days to advance scientific understanding of how continents separate and oceans are formed. Peate embarked on the 9-week expedition funded by the International Ocean Discovery Program with 125 other scientists and crew members from around the world, he explained in an interview with Iowa Now.

In the interview, Peate explained that when continents drift apart, the uppermost layer of the Earth’s crust is stretched so much that parts of a deeper layer called the mantle can ooze up into the crust. Sometimes the mantle is so hot that it rises up as lava and forms continental boundaries like those seen in eastern Greenland and northern Europe, he explained. Other times, the mantle rises at cooler temperatures and no lava is formed. The expedition’s primary mission is to understand the difference between these two types of continental rifts.

The continental rift in the South China sea is “different than other well-studied rifted margins. For one, it is not covered by thick piles of lava flows, unlike most other examples of continental rifting, which spawned lava flows,” he said.

The researchers’ ship is equipped with a three mile long steel tube that drills into the ocean floor to collect cores. “That is equivalent to the distance between the Old Capitol and Iowa City West High School,” Peate explained to Iowa Now. Once pulled up, cores are separated into five-foot lengths and prepared for geologists to study. Peate is mostly interested in volcanic rock. Some of the cores will return to Iowa with him. He said, “I will collaborate with other international scientists from the expedition to make detailed chemical investigations of all the volcanic rocks that we find.” Peate continued, “Combining results from the different drilled sites will allow us to build a picture of how the volcanic activity changed through time as the rifting event happened.”

Peate’s other areas of research include the formation and transport of magma in Iceland and the driving forces behind large magma eruptions. His compete interview with Iowa Now can be found here.


2017 locavore index released, Iowa slips in ranking

Locavore-Index-2017(Strolling of the Heifers) Jenna Ladd | May 18, 2017

For the sixth year in a row, Iowa’s position on the state locavore ranking has continued to slide downward.

Strolling of the Heifers, a farm and food advocacy organization out of Vermont, ranks the 50 states (plus Puerto Rico and the District of Columbia) by their dedication to local food each year. This year the group used seven metrics to rank states: farmers markets per capita, community-supported agriculture per capita, farm-to-school food programs, food hub programs, direct farmer-to-consumer sales, USDA local food grants per capita, and hospitals sourcing local foods.

The state of Iowa was ranked 18th in 2017, a far cry from its second place ranking in 2012. Iowa has slid down the list each year, ranking 10th in 2014, 13th in 2015, and 14th last year. According to this year’s report, Iowa ranked in the top ten for farmers markets per capita and community-supported agriculture per capita. However, the state ranks 50th for local food-to-school programs. Iowa performs in the middle of the pack when it comes to direct farm-to-consumer sales and USDA local food grants per capita.

The 2017 index features a new metric: hospitals sourcing local foods relative to the state’s population. Hospitals and local food organizers in Vermont have led the way, but the report notes that healthcare centers across the country have been pushing for 10 to 20 percent locally-sourced food in recent years.

Steven R. Gordon is President and CEO of Brattleboro Memorial Hospital in Brattleboro, Vermont. He said,

“Brattleboro Memorial Hospital is proud to be a leader in supporting local farms and producers of fresh and healthy food. Sourcing local produce not only supports our local economy but also helps our patients heal faster. Often times, when a person is ill or on various medications, their appetite diminishes and their tastes are altered. Providing our patients with in-season and locally-produced food allows us to provide meals with high flavor and nutrition.”

The state of Iowa ranked just inside the top 20 for local foods served in hospitals. The Vermont Association of Hospitals and Health Systems explains their journey to a more sustainable food system for hospitals and the benefits they’ve reaped thus far in the video posted below.


Scientists find 38 million pieces of trash on remote Pacific island

When researchers traveled to a tiny, uninhabited island in the middle of the Pacific Ocean, they were astonished to find an estimated 38 million pieces of trash washed up on the island.

A new study published Monday in the Proceedings of the National Academy of Sciences estimated that there were 17.6 tons of debris on the shores of the tiny island. The world produces that amount of plastic every 1.98 seconds, the researchers wrote.

Over 99 percent of the debris is made of plastic—most pieces are unidentifiable fragments.  The researchers say that fishing-related activities and land-based sources seem to have produced the majority of the debris.

The researchers say the density of trash was the highest recorded anywhere in the world, despite Henderson Island’s extreme remoteness. The island is located about halfway between New Zealand and Chile and is recognized as a UNESCO world heritage site.

Researchers found that most items on the island came from China, Japan or Chile.  (Jennifer Lavers, AP)

Dr. Jennifer Lavers, a research scientist at the University of Tasmania in Australia, was the lead author of the report.

What’s happened on Henderland Island shows there’s no escaping the effects plastic pollution even in the most distant parts of our oceans, said Lavers in a press release discussing the study.

“It speaks to the fact that these items that we call ‘disposable’ or ‘single-use’ are neither of those things,” she said, “and that items that were constructed decades ago are still floating around there in the ocean today, and for decades to come.”


Scientists find that less tilling means more earthworms

Wriggly earthworms are the unsung heroes of agricultural fields around the world. Their tiny bodies make it easier for water and air to enter the soil, transform organic matter into nutrients that is available to plants and can improve crop productivity by more than 50 percent.

A study recently published in the journal Global Change Biology sought to better understand which agricultural conditions are optimal for worms. Dr. Olaf Schmidt and Dr. Maria Briones analyzed 215 studies from over 40 countries that explored the relationship between tilling practices and worm population health.

The meta-analysis showed that disturbing the soil less (i.e. no-till farming, conservation agriculture) resulted in significantly more abundant earthworm populations. For example, no-till farmland saw a 137 percent increase in worm populations and a nearly 200 percent increase in soil biomass. Those areas of land in reduced-till for more than ten years saw the most earthworms return to the soil. In contrast, those field that were heavily plowed lost half of their original worm population.

Researchers observed the affect of tilling on 13 species of worms and found that the largest species were most heavily impacted. These creatures, called anecic earthworms, live deep down in the soil. At night-time they wriggle up a single channel, grab food, such as plant matter or manure, and then slide back down the same permanent burrow.

The researchers write that restoring earthworm populations through practing reduced-till or no-till farming “will ensure the provision of ecosystem functions such as soil structure maintenance and nutrient cycling by “nature’s plow.””

This On the Radio Segment discusses the recently released list of states in the U.S. that lead in the use of clean energy.

https://iowaenvironmentalfocus.files.wordpress.com/2017/05/unionofconcernedscientistsreport_82sec.mp3

Transcript: The Union of Concerned Scientists recently published its list of top ten states demonstrating “clean energy momentum,” and Iowa led the Midwest.

This is the Iowa Environmental Focus.

States were ranked according to twelve metrics that were organized into three broad categories: technical progress; direct, visible effects on our daily lives; and policies to build momentum for the future. California was at the top of the list as it was a top performer in eight of the twelve metrics. Other leading states included Vermont, Massachusetts, Rhode Island, Hawaii, Oregon, Maine, Washington, and New York.

Iowa rounded out the top ten list and was ranked first among Midwestern states. The Hawkeye state was the first to generate more than 30 percent of its energy from wind and is expected to source more than 40 percent of its total energy from wind turbines by 2020.

The publication pointed out that despite recent rollbacks of Obama-era climate policy, great strides have been made in renewable energy development. It notes that enough solar panels were added in 2016 to power two million houses.

Senate votes to preserve Obama-era methane gas regulation

The U.S. senate voted on Wednesday to uphold an Obama-era rule that limits the release of methane from oil and gas production on federal land.

The Republican-majority senate voted 51-49 to block the resolution. Three GOP senators, Susan Collins of Maine, Lindsey Graham of South Carolina and John McCain of Arizona voted with their democratic colleagues against the motion. Senate Republicans proposed  repealing the rule under the Congressional Review Act (CRA). So far in 2017, 14 regulations have been repealed under the CRA including a stream buffer rule aimed at keeping coal mining debris from entering waterways and another rule that gave the public some say about what happens to federal land.

President Obama updated the decades-old-rule that governs the venting and flaring of methane gas and regulates natural gas leaks. Upon the rule’s establishment, the Obama administration projected it could keep 41 billion cubic feet (BCF) of natural gas per year from going to waste. Methane, which is often released during the production of natural gas, is short-lived but 100 times more potent as a greenhouse gas than carbon dioxide.

Republican senator John McCain agreed with those hoping to keep the rule in place. He said, “Improving the control of methane emissions is an important public health and air quality issue, which is why some states are moving forward with their own regulations requiring greater investment in recapture technology.”

Opponents of the rule say that it discourages U.S. energy production and hurts state and county revenue streams. However, the Western Value Project estimates that the U.S treasury would have lost out on $800 million in royalties from oil and gas production over then next decade if the rule had been revoked.


Nordic nations demand Trump’s acknowledgement of climate change in Arctic circle

Representatives from eight Arctic nations will gather in Fairbanks, Alaska today for the 10th Arctic Council Ministerial Meeting.

At the meeting, the end of the United States two-year chairmanship of the council will be marked with a final statement summarizing U.S. accomplishments as chair. Officials from Canada, Denmark, Finland, Iceland, Norway, Russia and Sweden have not yet signed off on the statement because they say that the Trump administration deemphasizes climate change and the Paris climate accord in the document. The language of the document must be approved by all parties prior to its presentation for signing.

The other member countries say that President Trump has reversed the commitment that President Obama made to climate issues when the U.S. became chair in 2015. Along with Russia, the current administration has suggested opening up the Arctic to more drilling. The White House is also considering pulling out of the Paris climate pact, which was signed by over 200 nations in 2015.

Denmark, Finland, Iceland, Norway and Sweden recently made a joint statement pledging to take the lead on climate change and energy policy and firmly backing the Paris accord. At the ministerial meeting’s end, Finland will become head of council.

Although the current administration has taken decisive steps to dismantle climate change policy, David Balton, the State Department’s assistant secretary for oceans and international environmental and scientific affairs, said, “The U.S. will remain engaged in the work the Arctic Council does on climate change throughout. I am very confident there will be no change in that regard.”


U.S. drought levels at record low levels

5_9_17_Andrea_CC_droughttimeline_720_321_s_c1_c_cAfter years of widespread, intense drought, the US is experiencing its smallest drought footprint since 2000. (NASA Earth Observatory) Jake Slobe | May 10, 2017

After years of intense, record-setting drought, the U.S. is now experiencing its lowest level of drought in the 17 years since the U.S. Drought Monitor began its weekly updates.

Less than 5 percent of the U.S. was in some stage of drought as of May 4, the most recent update, compared to the 65 percent in drought in September 2012.

The last time drought levels across the country were this low was in July 2010, when 8 percent of the U.S. was in drought after which came a remarkable period of deep, damaging drought that led to billions in crop and livestock losses, spurred major water restrictions, and helped fuel terrible wildfires.

The ups and downs in drought levels could be linked to some of Earth’s natural climate cycles that can usher in relatively wet and dry periods. But climate change is likely to play a role as higher temperatures lead to increased evaporation and therefore worse drought conditions.

The epicenters of drought were in the central and southern Plains states from 2011 to 2013 and in California from 2012 to this winter. At the peak of its drought, more than half of California was experiencing “exceptional” drought conditions, the highest category of drought. At the end of September 2011, more than 85 percent of Texas was in this category as well.

Both droughts were fueled by a combination of dry weather and repeated, sizzling heat waves. The exceptional heat that blanketed much of the central and eastern portions of the country in 2012 boosted it to the hottest year on record for the U.S., while California experienced back-to-back record-hot years during its drought.

That heat is the clearest link between climate change and droughts, as rising global temperatures fueled by increasing concentrations of greenhouse gasses in the atmosphere tilt the odds in favor of record heat.

Studies have pointed to the role of climate change-fueled heat in California’s drought, and droughts in the future, no matter where they happen in the U.S., are likely to be more intense than those of today because temperatures will be higher on average.

 


Georgia wildfire inches closer to rural communities

Screen Shot 2017-05-09 at 9.28.54 AMThe Incident Information System regularly posts the latest developments in the West Mims Wildfire and other wildfires across the country. (InciWeb) Jenna Ladd | May 9, 2017

The West Mims Wildfire near the Georgia-Florida state line has been burning for weeks and shows few signs of slowing down.

The wildfire was ignited on April 6th when a lightening strike touched down inside the swampy Okefenokee National Wildlife Refuge. Since then, the fire has torched more than 133,000 acres and counting. Until this weekend, the wildfire did not pose a threat to humans in the area. After the fire crossed manmade fire breaks this weekend, an evacuation notice was sent out to residents of two small rural communities in Charlton county, St. George and Moniac.

By Monday, the fire had already burned about 37 square miles in Charlton county and 210 square miles total. Susan Heisey is supervisory ranger for the Okefenokee refuge. She said, “The accumulated moisture in the vegetation is at record-breaking lows right now. These fuels, they’re getting one little piece of ash and the fire’s just picking up and moving.”

A high pressure system in the southeast United States contributed to temperatures nearing 90 degrees Fahrenheit in the area on Monday, with humidity at just 20 percent. As temperatures remain high for the next few days and dry winds continue to blow across the West Mims fire, spokespeople for fire-fighting effort expect the fire to continue burning wherever fuel is available to it.

So far, there are 624 personnel working to keep the fire under control. A detailed incident report outlines predictions of the fire’s status over the next 72 hours. The report reads, “The drying trend will continue causing more fuels to become available to burn in the swamp. Fire activity will increase in areas that have not seen much heat over past few day. Re-burn potential remains very high.”

Climate change has lengthened the wildfire season in the U.S. by 78 days since the 1970’s. Rising temperatures and more frequent, intense droughts have contributed to more intense wildfires across the country.


On The Radio – Neonicotinoids found in University of Iowa drinking water

This On The Radio segment discusses the recent study that found neonicotinoids in UI drinking water.

https://iowaenvironmentalfocus.files.wordpress.com/2017/05/neonics.mp3

Transcript: A recent study by University of Iowa Researchers and the U.S. Geological Survey found neonicotinoids, a specific class of pesticides, in tap water for the first time ever.

This is the Iowa Environmental Focus.

Researchers compared tap water samples from the University of Iowa drinking water supply to samples of Iowa City municipal tap water. Water samples from both sources were tested for three primary types of neonicotinoids. The study found that the University of Iowa filtration system removed almost none of the neonicotinoids, while the City of Iowa City’s treatment plant successfully removed between 85 and 100 percent of each pesticide.

Dr. Gregory LeFevre is a University of Iowa environmental engineer and one of the study’s authors.

“Due to the proliferation of neonicotinoids in the environment and their chemical properties, we are not terribly surprise to find that they were present in drinking water. Most water treatment plants are designed to remove particles and pathogens like ecoli, but not trace pesticides. We were, however, more surprised by and encouraged to see how effective granular active carbon appeared to be at removing neonics from water.”

The U.S. Environmental Protection Agency has not set a limit for neonicotinoid levels in drinking water. Neonics became widely used by farmers in the early 1990s. The pesticides are still very popular, despite mounting research that suggests they are lethal to bees and other helpful insect species. The study’s authors argue that more research is called for to assess neonicotinoid exposure on a larger scale.

Iowa Flood Center featured in American Meteorological Association flagship publication

IFISIowa Flood Center’s Iowa Flood Information System was featured on the front page of the Bulletin of the American Meteorological Society this March. (Iowa Flood Center) Jenna Ladd | May 5, 2017

The Iowa Flood Center was featured in the March 2017 edition of the Bulletin of the American Meteorological Society, also known as BAMS.

BAMS is the flagship publication of the American Meteorological Society. The bulletin, which is released monthly, features scientific articles related to weather, water, and climate as well as news stories and editorials.

Witold Krajewski, the Iowa Flood Center’s director, is lead author on the article featured in BAMS. Titled “Real-Time Flood Forecasting and Information System for the State of Iowa,” the academic article provides a detailed understanding of the Iowa Flood Center’s (IFC) flood forecasting and information dissemination system.

IFC established the system following the record floods of 2008. Using scientific models and mathematical equations, the Iowa Flood Information System (IFIS) is able to provide rainfall and streamflow forecasts every fifteen minutes. Iowans from over 1,000 communities can access these real-time observations using the interactive IFIS web platform.

Prior to the development of this system, floods frequently occurred without warning in Iowa, as they did in 2008. The report reads,

“Devastating floods that inundated Cedar Rapids came as a surprise, leaving residents and businesses little time to evacuate; residents of Iowa City and the University of Iowa campus watched helplessly as floods compromised more and more buildings after the Coralville Dam lost its controlled-release functionality. Overall, the 2008 flood upended countless lives and livelihoods and caused between $8 billion and $10 billion in damages—at the time, the fifth-largest disaster in the history of the United States.”

Nine years later, the IFC is now able to consistently measures rainfall every five minutes across the state, and Iowans can have peace of mind heading into the rainy summer months.


2016 Iowa Farm and Rural Life poll released

15595785275_6000809424_o Jenna Ladd | May 4, 2017

Results from the Iowa Farm and Rural Life poll were released last month, providing insight into rural public opinion on a variety of topics.

The Iowa Farm and Rural Life poll, managed by the Iowa State University Extension Sociology, was established in 1982 and is the longest running survey of its kind. This year’s survey was completed by 1,039 farmers, who were 65-years-old on average. The poll is sent to the same 2,000 farmers every year so that researchers can track changes over time. This year, it asked respondents about conservation techniques, farming practices, monarch butterfly population restoration and trustworthy information sources.

According to the poll, 42 percent of farmers surveyed practice no-till farming, which can be effective in reducing topsoil erosion. On average, farmers lose 5.8 tons of topsoil per acre per year which can lead to a loss of 15 bushels of yield per acre each year, according to the Corn and Soybean Digest. Buffer strips along water ways and field edges to filter nutrients and sediment from runoff was the most common conservation practice among respondents. Forty-six percent of farmers reported using buffer strips in 2015, while fewer than 40 percent reported implementing extended crop rotations, terraces, or ponds.

The survey also asked about participation in The Natural Resources Conservation Service (NRCS) programs. NRCS is the arm of the U.S. Department of Agriculture charged with the protection of natural resources on agricultural lands. It provides technical and financial support to farmers looking to conserve soil and water. More than 60 percent of farmers said that they were currently participating in an NRCS program, just about 34 percent said that they were not. For those not enrolled in NRCS programs, their primary reason was that they did not believe they had enough natural resources on their land to warrant participation.

The farm poll also analyzed which sources of agricultural advice respondents were most likely to trust. More than any other source, farmers said they would be most likely to trust another farmer that grows nearby.

The survey is collaborative project of Iowa State University Agriculture and Home Economics Experiment Station, ISU Extension Service and the Iowa Department of Agriculture and Land Stewardship. “Information from the Farm Poll is used to guide policy decisions and actions and as the basis for public policy seminars, Extension reports, radio and television broadcasts, and newspaper and journal articles,” reads the Iowa State University Extension site.


Study finds that flood patterns are changing across the U.S.

regional-flood-risks-image2The threat of moderate flooding is generally increasing in the northern U.S. and decreasing in the southern U.S. (American Geophysical Union.) Jake Slobe | May 3, 2017

The risk of flooding is changing by region throughout the United States and two of the reasons could be shifting rainfall patterns and changes in groundwater.

University of Iowa engineers, in a new study, have determined that the threat of flooding is growing in the northern half of the U.S. while declining in the southern half. The American Southwest and West are experiencing decreasing flood risk.

UI engineers Gabriele Villarini and Louise Slater compiled water-height information from 2,042 stream gauges operated by the U.S. Geological Survey. They then compared the data to satellite information gathered over more than a dozen years by NASA’s Gravity Recovery and Climate Experiment mission showing the amount of water stored in the ground.

The study found that northern sections of the country have an increased amount of water stored in the ground and are at increased risk for minor and moderate flooding. Meanwhile, flood risk is decreasing in the southern portions of the U.S., where stored water has declined.

Why some sections of the nation are getting more, or less, rainfall is not entirely clear. The researchers say one cause could be the redistribution of rains as the regional climate changes.

The researchers hope their findings can change how flood patterns are discussed. In the past, flood risk trends have typically been discussed using stream flow, or the amount of water flowing per unit time. The UI study views flood risk through the lens of how it may affect people and property and aligns the results with National Weather Service terminology understood by the general public.


Extreme weather takes the lives of 14 people

Flooding and tornados swept across the Midwest and southern U.S. this weekend, leaving at least 14 people dead.

The National Weather Service reported that four tornados moved through eastern Texas beginning Saturday evening. The twisters left an area of destruction 35 miles long and 15 miles wide in Van Zandt County, according to Canton, Texas Mayor Lou Ann Everett. Primarily small towns were affected in the mostly rural area east of Dallas; four individuals lost their lives.

Strong winds and flooding in Arkansas took the lives of five residents near Madison county. Four additional deaths were reported in Missouri and Mississippi, also due to flash flooding and strong winds.

Tragically, severe weather events like these are becoming more common as climate change rears its ugly head. According to archived data from the U.S. Environmental Protection Agency’s webpage prior to President Trump’s inauguration, “In recent years, a larger percentage of precipitation has come in the form of intense single-day events.” Similarly, the amount of precipitation falling on the heaviest rain days has increased in the last few decades. Many regions of the U.S. are seeing significantly more severe river flooding, while other areas are ravaged by drought. The Midwest, Great Plains, and Northeast have seen a significant increase in flooding, but the Southwest has experienced a decrease.

Scientists are still evaluating the relationship between climate change and twisters. The EPA notes that climate change does lead to stronger and more frequent thunderstorms, which can cause tornados, but there is a lack of empirical data on the matter.

Researchers can confidently conclude that climate change has caused more intense and frequent heat waves, fewer frequent and less intense cold waves, and regional changes in floods, droughts, and wildfires.


On The Radio – Chicago public buildings to switch to renewable energy

ChicagoSkyline

Jake Slobe | May 1, 2017

This On The Radio segment discusses Chicago’s plan to convert its public buildings electricity use to 100% renewable energy by 2025.

https://iowaenvironmentalfocus.files.wordpress.com/2017/05/chicagoschools.mp3

Transcript: Chicago mayor Rahm Emanuel announced last month a plan to convert all of the city’s public buildings’ electricity use to 100% renewable energy by 2025.

This is the Iowa Environmental Focus.

The plan will consist of transitioning more than 900 government buildings in Chicago to renewable energy. Once implemented, Chicago will be the largest major city in America to have a 100% clean energy mandate for its public buildings.

Together, Chicago Public Schools, City Colleges, Chicago Park District fieldhouses and buildings owned by the city and the Chicago Housing Authority consume 8 percent of all the electricity used in Chicago, according to city officials. Last year, that amounted to nearly 1.8 billion kilowatt hours — enough to power 295,000 Chicago homes.

The 900 government buildings will accomplish the shift through a variety of including purchasing “renewable energy credits,” buying utility-supplied renewable energy through the Illinois Renewable Portfolio Standard, and by installing solar panels or windmills on city buildings and public property.

The City Colleges have installed solar panels on the roofs of Richard J. Daley College and the Dawson Technical Institute. Those installations alone have generated more than $16,000 in energy savings.

People’s Climate March set for this Saturday

15314270532_8854330732_oDemonstrators gather at the first People’s Climate March on September 21, 2014 in New York City. (Doug Turetsky, flickr) Jenna Ladd | April 28, 2017

The People’s Climate March will take place this Saturday, on President Trump’s 100th day in office.

The National Park Service has approved a permit for 50,000 to 100,000 to gather on Washington D.C.’s National Mall to advocate for action on climate change. This march comes exactly one week after the March for Science, but Thanu Yakupitiyage, national communications manager for 350.org said this demonstration has a different focus. In an interview with the Washington Post, she said, “The March for Science was really the response of scientists who felt that there was really an assault on rationality and science. This is really more of a community response.”

The first People’s Climate March was held in September of 2014 when over 400,000 people marched through New York City on the day before the UN Climate Summit. Ever year since then, the People’s Climate Movement has organized multiple demonstrations that “Prioritize leadership of front-line communities, communities of color, low-income communities, workers and others impacted by climate, economic and racial inequity.”

While the main event will take place in the nation’s capital, hundreds of other demonstrations are expected to take place around the U.S. Iowa City will host its march titled, “Unifying to Protect Life on Earth” on Saturday, April 29 from 1:30 pm to 3:00 pm. Protesters will meet on the North side of the Sheraton Hotel in the pedestrian mall to “march together for rational military spending, social justice, a living wage, and an ecosystem that flourishes,” according to the event’s webpage.

Another march will be held at the Iowa State Capitol on Saturday from 1:00 pm to 3:00 pm. The Des Moines event is sponsored by a diverse group of organizations including the Sierra Club, Indigenous Iowa, the League of United Latin American Citizens, Interfaith Green Coalition and the Citizens Climate Lobby, among others.

The massive climate-action demonstration will take place just three days after President Trump issued an executive order to reevaluate the status of nationally protected lands, possibly freeing them up to drilling for fossil fuels and other types of resource extraction.


Attorneys general, large businesses urge Trump administration to remain in Paris Climate Agreement

Fourteen attorneys general sent a letter to President Trump on Tuesday urging him not to withdraw from the Paris Climate Agreement.

The United States agreed to the Paris accord along with 200 other nations during the Conference of the Parties 21 (COP21) in 2015. Each country that signed on agreed to take some action to improve environmental conditions, mostly by reducing fossil fuel emissions that cause climate change. For its part, the U.S. pledged to bring its emission levels 26 percent and 28 percent below 2005 levels before 2050.

Tuesday’s letter was signed by top ranking prosecutors in Iowa, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New York, North Carolina, Oregon, Rhode Island, Vermont, the District of Columbia and American Samoa. It read, “The Paris Agreement, by securing commitments from countries the world over, reflects this collective interdependency and constitutes an unprecedented global effort to address a problem threatening the well-being of everyone on Earth.”

The White House also received a letter from several major businesses in support of staying in the Paris agreement. On Wednesday, Apple, DuPont, General Mills, Google Intel, Shell and Walmart, among others, wrote to the President,

“Climate change presents U.S. companies with both business risks and business opportunities. U.S. business interests are best served by a stable and practical framework facilitating an effective and balanced global response. We believe the Paris Agreement provides such a framework.”

Trump Administration officials will meet today to discuss whether the U.S. should leave the Paris Agreement or stay the course. President Trump pledged to “cancel” the agreement during his campaign, but some of his top officials like Secretary of State Rex Tillerson are in support of the accord.

White House press secretary Sean Spicer said in a press conference that a decision will be made by “late May-ish, if not sooner.”

 


New Trump executive orders will take aim at protected public lands, offshore drilling bans

After moving last month against Barack Obama’s efforts to limit fossil fuel exploration and combat climate change, President Trump will complete his effort to overturn environmental policy this week by signing two executive orders to expand offshore drilling and roll back conservation of public lands.

Today, Trump will sign an executive order directing his interior secretary, Ryan Zinke, to review national monuments designated by previous presidents under the Antiquities Act of 1906, aiming to roll back the borders of protected lands and open them to drilling, mining, and logging.

President Trump is then expected to follow up on Friday with another executive order that will aim to open up protected waters in the Atlantic and Arctic Oceans to offshore drilling. If signed, the order would eliminate the Obama administration’s plan that would have put those waters off limits to drilling through 2022. Friday’s order is also expected to call for the lifting of a permanent ban on drilling in an area including many of those same waters — a measure Obama issued in December 2016 in a last-ditch effort to protect his environmental legacy.

These moves, according to the Trump administration, will begin to fulfill a central campaign promise to unleash a wave of new oil and gas drilling and create thousands of jobs in energy.

The reality is much more complicated say experts in the law, policy, and economics of energy. Legal experts say it will still be a heavy lift for the Trump administration to change the current laws. The orders are unlikely to lead to job creation in the near future or significant new energy development.


Iowa general assembly adjourns, still no water quality funding

The Iowa Natural Resources and Outdoors Trust Fund remains empty after legislators adjourned the 86th General Assembly on Saturday without passing policy to fund water quality improvement in the state.

Long-term funding for water quality was not included in next year’s $7.2 billion state budget, even though the vast majority of Iowa voters supported establishing the fund more than seven years ago. The House and Senate each devised their own plans for funding, but neither plan garnered support from both houses.

Legislators in the Senate proposed an amendment that would have increased Iowa’s sales tax by three-eighths of one cent. The plan would have generated around $180 million dollars per year for the Iowa Natural Resources and Outdoors Trust Fund, 60 percent of which would have gone to water quality improvement projects. The proposal was championed by Iowa’s Water and Land Legacy, a coalition of environmentalists, political leaders and Iowa businesses dedicated to promoting water and land conservation measures. Although the sales tax increase had support on both sides of the aisle, it lost in the Senate vote 34 to 16.

The Iowa House of Representatives proposed a plan that would have redirected money from a sales tax Iowans already pay on tap water to water quality improvement projects. The 6 percent tax currently funds infrastructure projects for community school districts and other municipal projects. The plan was approved by the House, even though some Democrats criticized the it for cutting funds from other state programs.

Kirk Leeds is CEO of the Iowa Soybean Association (ISA). In an interview with CBC, he said, “This year’s legislative session was a missed opportunity to act boldly on improving Iowa’s water.” Leeds continued, “ISA will seek continued partnerships with farmers and cities to make real progress on conservation to the benefit of all Iowans.”
