Q&A on the Trump EPA’s Effort to Curtail Regulation of Greenhouse Gas Emissions

Q&A on the Trump EPA’s Effort to Curtail Regulation of Greenhouse Gas Emissions

The Environmental Protection Agency is holding public hearings this week on its effort to undo the legal foundation for its regulation of greenhouse gases, the heat-trapping gases that cause climate change. In a major policy shift announced in late July, the Trump administration EPA said it would rescind the so-called “endangerment finding,” which allows the agency to regulate such emissions, arguing that legal and scientific developments justify a reconsideration.

Will Global Warming Benefit Civilization?

Environmental Protection Agency head Scott Pruitt suggests that global warming isn’t necessarily “a bad thing” because “humans have most flourished during times of … warming.” But recent years have been the warmest humans have seen over at least the last millennium.

Hurricane Harvey and Climate Change

Hurricane Harvey and Climate Change

Hurricane Harvey has brought with it both a record amount of rain and questions about how much climate change can be blamed for the storm. Climate change did not cause Harvey, or any other storm, but it makes intense storms like Harvey more likely to occur, scientists say.

CO2: Friend or Foe to Agriculture?

CO2: Friend or Foe to Agriculture?

Rep. Lamar Smith said climate change “alarmists” ignore the “positive impacts” of more carbon dioxide in the atmosphere, such as increased food production and quality. But the impact of increased CO2 levels on agriculture is more complicated than that — and, on balance, likely negative, particularly in the future.
