Despite Major Improvements, Levels of Air Pollution in the U.S. Are Still Unsafe

By Roberta Attanasio, IEAM Blog Editor

Air pollution not only threatens the future of our climate by significantly contributing to global warming, it also causes some of our most common illnesses, accounting for 1 in 8 deaths worldwide.  It’s an invisible killer that is globally responsible for 36% of deaths from lung cancer, 35% of deaths from pulmonary disease, 34% of deaths from stroke, and 27% of deaths from heart disease, according to the World Health Organization (WHO).

The Arctic is Opening Up: Offshore Drilling and Melting Sea Ice

By Roberta Attanasio, IEAM Blog Editor

The heat is on in the Arctic. This region is now warming at a rate faster than twice the global average—known as Arctic amplification. Consequently, the ice that covers the North Pole and surrounding areas, and melts to its lowest extent each September, has been disappearing at an alarming rate. Continue reading

Clean Power Plan, New Ozone Standard, and Asthma

On August 3, 2015, the Obama administration announced the finalized US Environmental Protection Agency’s (EPA) “Clean Power Plan.” The plan has been developed under the Clean Air Act and aims to slash carbon emissions from US power plants, which account for one-third of all carbon emissions in the country, by giving each state an individual goal for cutting these emissions. The EPA estimates that the new national standards will significantly decrease carbon pollution produced by the electric sector by 2030; carbon emissions will be 32% lower than the 2005 levels. For a step-by-step guide on how the Clean Power Plan works, head here. Continue reading

One of the Best Climate Communication Talks I Have Seen

A guest post by Marshall Shepherd, Director of the Atmospheric Sciences Program, University of Georgia, and author of the Weather Underground blog “From the Mind of J. Marsh WxGeeks Edition”

On April 15, 2015, at the University of Georgia, I wandered over to the Miller Learning Center to hear a talk by Dr. Steve McNulty (Link) with the United States Forest Service and the USDA Southern Regional Climate Hub (@SEClimateHub).

Let me start by saying this was one of the best and most effective climate communication talks that I have ever seen. It was so good that I felt compelled to write this blog to share some of it with you. Continue reading

Global Climate Change: Driver of Infectious Diseases?

The impacts of global climate change on human health and well-being are undeniably alarming. Safe drinking water, sufficient food, and secure shelter are threatened by rising sea levels and severe weather events. Heat waves dramatically increase death rates not only from heat strokes, but also from complications arising from cardiovascular, respiratory, and cerebrovascular diseases. According to the WHO, climate change is expected to cause approximately 250,000 additional deaths per year between 2030 and 2050, mostly from malnutrition, malaria, diarrhea, and heat stress. Unfortunately, these estimates take into account only a subset of the possible health impacts and assume continued economic growth and health progress. The global situation is likely to be much worse. Continue reading

Unexplored Links: Climate Change and Environmental Contaminants

Climate change is happening here and now, and the rate of change is also speeding up, as demonstrated by a recent study. The most dramatic effects are clearly visible all around us—shifting precipitation patterns, sea level rise, ocean acidification, shrinking Arctic sea ice, melting of the Greenland and Antarctica ice sheets, and amplified occurrence of wildfires, floods, heat waves, and droughts. Climate change is also a threat multiplier—the environmental fallout it causes can exacerbate political instability in the world’s most dangerous regions and increase the chances of armed conflict. In addition to these conspicuously damaging effects, there are some others that are causing alarm, although not discussed as often and not as clearly discernible at this time: climate change may alter the release, dispersal, and toxic effect of chemicals in the environment, potentially resulting in dangerous levels of human exposure and deleterious consequences for ecosystems.

Climate Scientists Weigh-in on Scientific Disagreement and Public Trust

A guest post by Kirk Englehardt, Director of Research Communication, Georgia Institute of Technology

A new report by the Pew Research Center explores many ways scientists engage with the public – and why.

The study is based on a survey of more than 3,700 members of the American Association for the Advancement of Science. It reveals that scientists who study areas that are regularly debated in the media are more likely to engage in public outreach than those working in less controversial areas. They’re also more likely to speak with reporters and blog about their research. Continue reading
