Climate Change

Genetics may be the key to saving California's ancient coastal redwoods from the climate change that threatens them.

"Governments are slowly advancing efforts to reduce climate and health impacts of soot."

"Governments are poised this week to begin discussing rules to curb black-carbon pollution from ships, after nearly seven years of preparation. The sooty emissions, which are produced by diesel engines, warm the climate and harm human health.

"A group of Democratic senators is demanding that Environmental Protection Agency chief Scott Pruitt recuse himself from  repealing one of President Obama's signature environmental rules, which is intended to curb the release of greenhouse gases from the nation’s power plants."

"As head of the Environmental Protection Agency, Scott Pruitt has repeatedly questioned the scientific consensus that rising levels of carbon dioxide from human-fueled activity are warming the planet. He’s now taking a different tack: Even if climate change is occurring, as the vast majority of scientists say it is, a warmer atmosphere might not be so awful for humans, according to Pruitt."

"The political fight over global warming has extended to science education in recent years as several states have attempted to weaken or block new teaching standards that included information about climate science. But only in Idaho has the state legislature stripped all mentions of human-caused climate change from statewide science guidelines while leaving the rest of the standards intact."

"The rescue of the planet’s protective ozone layer has been hailed as one of the great success stories of modern environmental regulation — but on Monday, an international team of 22 scientists raised doubts about whether ozone is recovering as expected across much of the world."

"The Trump administration has missed a deadline to submit a report to the United Nations on climate change action."

"Due to heavy fertilizer use, California's Central Valley is behind up to 41 percent of the state's emissions of nitrogen oxide — an air pollutant and climate-warming gas".

"A large proportion of California's nitrogen oxide—which can cause harmful ozone and a variety of health impacts—comes from heavy fertilizer use in the state's Central Valley, according to a new study.

As climate change melts Arctic permafrost, it will release toxic mercury, scientists say.

"Anchored in flood-prone areas in every American state are more than 2,500 sites that handle toxic chemicals, a New York Times analysis of federal floodplain and industrial data shows. About 1,400 are located in areas at highest risk of flooding."
