Trump Attacks State Climate Laws, Eco Rollbacks Under Trump, Air Pollution Mixes and Public Health, Shrinking Clouds and more

President Trump has issued an executive order that directs the U.S. attorney general to identify and block state laws that deal with climate change, environmental justice, and carbon emissions. A study from Johns Hopkins researchers found that residents near or on the fence line of polluting enterprises are at higher risk for multiple health problems because of the toxic mix of air they breathe. The lead researcher explains the study. In terms of physics, global warming comes down to an energy imbalance as Earth is taking in more energy than it is releasing. An atmospheric scientist explains how a shrinking cloud cover is contributing to climate change.
