EPA's top air quality regulator William Wehrum, who has faced sharp criticism for his past work with polluting industries, is departing the agency at the end of this month, EPA administrator Andrew Wheeler said Wednesday.

Why it matters: Wehrum, an attorney who has represented coal-fired power producers and other industry clients, is a key architect of some of the Trump administration's efforts to soften Obama-era policies.

Higher temperatures could fuel a global energy demand to stay cool

A new peer-reviewed study finds that higher temperatures could bring large increases in energy demand as use of cooling soars, far outweighing reduced need for heating.

Why it matters: The paper published in Nature Communications finds that depending on future warming levels, global demand in 2050 could be 11%–58% higher than what's otherwise expected based on economic development and population growth.
