Climate change poses a growing threat to American schools. Regions where extreme heat was once rare — from the Northeast to the Pacific Northwest — now periodically find their buildings unbearably hot as spring turns to summer and again when classes resume in August or September. In much of the South, air conditioning has long been a necessity, and schools are typically outfitted with centralized systems, although rising temperatures may require upgrades.

Another oil well was discovered leaking methane in Bakersfield over Memorial Day weekend, with levels again topping out at 50,000 parts per million on inspection equipment. The latest report brings to 14 the number of wells discovered in two weeks near homes to be emitting the colorless, odorless gas, a powerful greenhouse gas that can also explode at 50,000 ppm or above. Air toxics are also often emitted along with methane from leaking wells, though no tests for those have been announced or any results released.

A historic agreement sets aside what was destined to be a protracted legal battle between the Navajo Nation and the state of Utah over rights to water in the Colorado River. With that agreement comes nearly $220 million in funding for the Navajo to provide drinking water to 40% of the tribe in Utah that lacks access to clean, running water.

The American Lung Association released its 2022 State of the Air report Wednesday, a look at which areas and people are suffering from the worst air quality, and researchers say the findings are clear — climate change and wildfires are making air quality, particularly in Western states, much worse.

GENEVA -- The U.N. health agency says nearly everybody in the world breathes air that doesn’t meet its standards for air quality, calling for more action to reduce fossil-fuel use, which generates pollutants that cause respiratory and blood-flow problems and lead to millions of preventable deaths each year.
