Researchers from Harvard University published a study that analyzes the economic and public health benefits of implementing a U.S. power plant carbon standard similar to the Clean Power Plan. The study estimates that a U.S. power plant carbon standard could bring net benefits close to $38 billion annually.

Exposure to lead, mercury and organophosphate pesticides has led Americans to lose a collective 41 million IQ points, according to a study by a Harvard neurologist, and other common chemicals could be responsible for everything from ADHD to autism-spectrum disorders. Researchers compare the problem to climate change and say it's important for regulators to act even before the development of clear scientific evidence for safe exposure levels. "We don't have the luxury to sit back and wait until science figures out what's really going on," says environmental health researcher Philippe Grandjean

Geoengineering technologies such as injecting sulfur into the atmosphere to offset carbon dioxide will begin to seem less like science fiction and more like a reasonable solution, argues David Keith of Harvard Kennedy School. Not everyone's convinced that's a good idea, though. "Solar climate engineering is a flawed idea seeking an illusory solution to the wrong problem," counters Mike Hulme of King's College London.

The Environmental Protection Agency's power plant emissions rules would save about 3,500 lives a year and have many other positive health effects, according to researchers at Syracuse and Harvard universities. The emissions reductions mandated by the rules would lead to 1,000 fewer heart attacks and other hospitalizations from air-pollution-related illness annually, the study found. 

Four representatives recently introduced a bill called the Food Donation Act of 2017 (H.R. 952), which addresses some of the greatest barriers that restaurants and food service companies face when they want to give away their excess edible food. This bill clarifies and enhances the coverage areas of the Bill Emerson Good Samaritan Food Donation Act, the legislation that made the donation of excess food from businesses to people in need legally protected.

The Department of Defense is clear-eyed about the challenges climate change poses. "The pressures caused by climate change will influence resource competition while placing additional burdens on economies, societies, and governance institutions around the world," the most recent Quadrennial Defense Review, issued in 2014, states. "These effects are threat multipliers that will aggravate stressors abroad such as poverty, environmental degradation, political instability, and social tensions-conditions that can enable terrorist activity and other forms of violence."

Researchers from the Environmental Defense Fund, Harvard University and Princeton University have proposed that scientists use different and more precise measurements when predicting global warming trends, particularly by measuring carbon emissions on both 20- and 100-year scales. The researchers believe this dual-measurement system would help organizations and governments see both the short- and long-term benefits of different energy projects.
