UI Center for Global and Regional Environmental Research co-director Dr. Gregory Carmichael delivered the 34th Annual Presidential Lecture to a crowded assembly hall at the Levitt Center for University Advancement on Sunday.

The lecture, titled “What Goes Around, Comes Around: The Global Reach of Air Pollution” featured opening remarks from University of Iowa President Bruce Harreld. Quoting Dr. Jerry Schnoor, Carmichael’s co-director at CGRER, President Harreld joked, “Greg is now more traveled than George Clooney’s character in Up in the Air, four million miles and counting.” Carmichael’s extensive research of the long-range transport of air pollution has taken him to many parts of Eastern Asia, South America, Africa and Europe, among other locations.

Carmichael’s lecture was organized into three parts: the global reach of air pollution, the link between climate change and air pollution, and a finally, a discussion about the action necessary to curb air pollution worldwide. The lecturer made a strong case for air pollution research, citing that it is the root cause of 7 million avoidable deaths per year. Carmichael pointed out that air pollution has economic consequences too; each year, it leads to loss of 10 percent of U.S. soybean yields.

The lecture encouraged a sense of urgency when it comes to cleaning up the atmosphere. Carmichael warned, “That molecule that we put in the air today will stay in the air for a long time.” He went on to say that 20 percent of carbon dioxide released into the atmosphere today will remain there for thousands of years. Professor Carmichael’s research focuses primarily on the utilization of comprehensive computer models and big data to simulate the interplay of air pollutants with weather and climate.

His work has been instrumental in understanding the way in which air pollutants from China move across the Pacific Ocean and affect the Western U.S. He said, “Fifteen to twenty percent of clean air policies in the Western U.S. are being offset by Chinese emissions.”

Above all, the Karl Kammermeyer professor of chemical and biochemical engineering emphasized his passion for instructing and advising students. Carmichael has supervised the research of 40 PhD and 35 Masters of Science students at the University of Iowa.

Risk of extreme wildfires to increase as climate warms ​finds study

The likelihood of extreme wildfires, or “megafires,” across the world is expected to increase as global temperatures continue to rise, a new study says.

The research, published in Nature Ecology & Evolution, uses satellite data to identify the 500 most extreme wildfires in recent years. Almost a third of these mega-fires caused deaths, burned down homes, or were declared a disaster by a national government.

Using climate change projections for the middle of this century, the study predicts there will be a 35% increase in the days with a high danger of fire across the world. Some regions will see even larger increases, say the researchers, including western states in the US, southeastern Australia, the Mediterranean and southern Africa.

The study uses satellite data collected by imaging instruments aboard two NASA satellites, Terra and Aqua. Using this data, the researchers identified more than 23 million wildfires globally between 2002 and 2013. While the most severe fires are often loosely dubbed “megafires”, the researchers went a step further by identifying the 500 most extreme wildfires to carry forward for their analysis.si

Of the 500, 22 were ruled out as they were caused by volcanic eruptions or industrial fires. With the remaining 478, the researchers assessed which ones could be classed as “disasters.” There are many definitions of wildfire disasters, the researchers note, many of which focus on the economic impacts – but there is no consistent global database for this. So the researchers based their definition on whether an emergency was declared or the fires caused death or loss of property. For this, they used national disaster databases, news reports and internet searches.

96%  of these disastrous mega fires occurred during periods of unusually hot and/or dry weather, the researchers say.

 

The study projects how the Fire Weather Index (FWI) – an estimate of wildfire risk based on weather conditions and how dry the landscape is – will change the world in future. They look specifically at the changes in “high” fire danger under a climate change scenario where global CO2 emissions aren’t curbed.

 

Congressman Chaffetz to kill House Bill 621 following public opposition

House Republicans are expected to throw out a bill on Friday that would have sold off more than 3 million acres of federal public lands.

Environmental conservationists and hunters joined forces to oppose House Bill 621 after Republican Congressman Jason Chaffetz announced it last week. The bill would have ordered the Department of Interior to immediately sell off 3.3 million acres of “disposable” land across ten western states, claiming that the land served “no purpose for taxpayers.”

Jason Amaro is a sportsman with the south-west chapter of Backcountry Hunters and Anglers. He said, “Last I checked, hunters and fishermen were taxpayers. That word ‘disposal’ is scary. It’s not ‘disposable’ for an outdoorsman.” Public lands in the Western U.S. provide habitat for elk, gray wolves, and grizzly bears, a vast playground for outdoor enthusiasts, and can be leased out for timber, oil, and gas extraction. The Wilderness Society values the national outdoor recreation economy at just over $646 billion.

Chaffetz said he feared the bill “sent the wrong message” on Thursday and pledged to rescind it on Friday. The Tea Party Republican commented below an Instagram photo of himself wearing hunting gear outdoors. He said, “I’m a proud gun owner, hunter and love our public lands. I hear you and HR 621 dies tomorrow.” Chaffetz’s comment came after many opponents of the bill overwhelmed his Instagram account with comments asking him to “#keepitpublic” and “say no to HR 621.”

Although President Trump is in favor of utilizing more public lands for oil and gas extraction, he has stated that he is opposed to selling off federally owned lands. In an interview with Field & Stream, he said, “I don’t think it’s something that should be sold.” The President is also opposed to giving states ownership of public lands. He added, “I don’t like the idea because I want to keep the lands great, and you don’t know what the state is going to do.”

Co-director of the University of Iowa Center for Global and Regional Environmental Research (CGRER), Gregory Carmichael, will give this year’s University of Iowa Presidential Lecture.

Carmichael became faculty at the University of Iowa in 1978 after earning a BS in chemical engineering at Iowa State University and a PhD from the University of Kentucky. Nearly four decades later, the Karl Kammermeyer Professor of Chemical and Biochemical Engineering remains devoted to studying the global impact of pollution on air quality.

In an interview with IowaNow, Carmichael recounts how he initially became interested in air quality issues. He said, “At the time I was doing my graduate studies, acid rain was emerging as a big problem. That was really the first air pollution problem that demonstrated to people that we could have an impact beyond our local environment.”

Carmichael has won several awards including the Regents Faculty Recognition Award in 1998, the American Institute of Chemical Engineers Lawrence K. Cecil Award in 2012, NASA Group Achievement Awards in 2005 and 2009. Over time, Carmichael’s research became increasingly international. In the most recent fifteen years, his research team has has conducted air quality forecasting field experiments in Chile, California, the Arctic, and Beijing.

Much of his research considers how air pollution travels intercontinentally. He said, “We have done a lot of work on this topic over time, and this long-range transport of pollution is now being taken into consideration in the management of U.S. air quality and in international discussions. Wherever the emissions are occurring, they have an impact not only locally but globally as well.”

Carmichael became co-director of CGRER in 1991, and currently serves alongside Dr. Jerry Schnoor, University of Iowa professor of Civil and Environmental Engineering.

University of Iowa alumnus receives BBVA Frontiers of Knowledge Award

University of Iowa Alumnus James Hansen has been honored with the BBVA Foundation Frontiers of Knowledge Award in the Climate Change category.

The BBVA Foundation promotes, finances, and developments research projects in Biomedicine and Health, Environment, Economy and Society, Basic Sciences and Technology, and Arts and Humanities on behalf of the BBVA Group, a multinational banking group headquartered in Bilbao, Spain.

Hansen received the Frontiers of Knowledge Award along with Japanese climatologist Syukuro Manabe. The two men independently developed the first computation models with the ability to simulate climate behavior, and pioneered the “use of these models to understand and project how Earth’s climate responds to changing concentrations of atmospheric CO2,” said the BBVA’s prize jury.

Originally from Denison, Iowa, Hansen earned his Bachelors, Masters, and PhD from the University of Iowa in Physics. He studied under renowned physicist James VanAllen in the space studies program in the late 1960’s. In 1967, Hansen joined NASA’s Goddard Institute for Space Studies. While researching planetary atmospheres at the Institute, Hansen was instrumental in establishing that Venus’ extremely hot temperatures were due to a greenhouse gas effect.

As CO2 levels in Earth’s atmosphere continued to rise throughout the 1970’s, Hansen shifted his focus and began to study the effect of CO2 on climate. He developed a computational model independently from Manabe, and his conclusions were published in the Journal of Science in 1981. The BBVA prize jury points out that this research was important because it was the first ever to incorporate global temperature data and to predict how global warming would affect other earth processes such as oceanic circulation and flooding.

Manabe said, “I started working with models earlier, but Hansen was the first to use these models to make predictions.”

Hansen served as Director of NASA’s Goddard Institute for Space Studies from 1981-2013. He is now an adjunct professor at Columbia University’s Earth Institute where he has led the Climate Science, Awareness and Solutions program since 2013.

Anti-smog police: one part of Beijing’s fight for air quality

A new environmental police force is taking to the streets of Beijing to combat the city’s dangerous smog problem.

Beijing’s mayor, Cai Qi, announced this weekend that the officers will patrol the city looking for “open-air barbecues, garbage incineration, biomass burning, [and] dust from roads” that add to the city’s smog problem. Cai Qi’s announcement comes after Beijing experienced particularly dangerous air quality during the first week of 2017, and 72 Chinese cities were placed under pollution alerts.

Mayor Cai Qi said, “I totally understand the public’s concerns and complaints over air pollution,” and admitted to routinely checking the air quality index “first thing in the morning.”

The mayor announced that the city is taking additional measures to improve air quality. Beijing will close its only coal-fired plant, and in 2017 “coal consumption will be cut by 30 percent to less than 7 million tonnes” and “another 300,000 high-polluting old vehicles will be phased out,” according to China’s state-run Xinhua news agency.

Despite last week’s “red alert,” which temporarily shut down some pollution-producing operations, China’s environment ministry found that some 500 construction sites and businesses as well as 10,000 vehicles remained active in violation of the ban.

Chinese officials acknowledge that industry and automobiles are the primary causes of the hazardous smog problem, but reports state that the government is hesitant to crack down on major polluters in fear of economic consequences.

A study published in the November edition of the journal Science of the Total Environment, found that smog is related to one-third of all deaths in China, amounting to at least one million deaths per year.
