WASHINGTON — Scientists think they’ve figured out the falling dominoes that led to Earth’s largest mass extinction and worry that human-caused climate change puts the planet on a vaguely similar path.
WASHINGTON — Both nature and humans share blame for California’s devastating wildfires, but forest management did not play a major role, despite President Donald Trump’s claims, fire scientists say.
WASHINGTON — Earth’s protective ozone layer is finally healing from damage caused by aerosol sprays and coolants, a new United Nations report said.
The ozone layer had been thinning since the late 1970s. Scientist raised the alarm and ozone-depleting chemicals were phased out worldwide.
WASHINGTON — Over the past few decades tornadoes have been shifting decreasing in Oklahoma, Texas and Kansas but spinning up more in states along the Mississippi River and farther east, a new study shows. Scientists aren’t quite certain why.
OXFORD, Pa. — A staple of summer ‚Äî swarms of bugs ‚Äî seems to be a thing of the past. And that’s got scientists worried.
Pesky mosquitoes, disease-carrying ticks, crop-munching aphids and cockroaches are doing just fine. But the more beneficial flying insects of summer ‚Äî native bees, moths, butterflies, ladybugs, lovebugs, mayflies and fireflies ‚Äî appear to be less abundant.
WASHINGTON — Language detectives say the key clues to who wrote the anonymous New York Times opinion piece slamming President Donald Trump may not be the odd and glimmering “lodestar,” but the itty-bitty words that people usually read right over: “I,” “of” and “but.”
And lodestar? That could be a red herring meant to throw sleuths off track, some experts say.
WASHINGTON — A new study finds that fireflies flash not just for survival, not just sex.
Scientists already know that lightning bugs used their signature blinking glow to find a mate, but they suspected something else was going on. Boise State University researchers found it also keeps them from being eaten by bats.
They published a study in Wednesday’s Science Advances.
As temperatures rise in the U.S. West, so do the flames.
The years with the most acres burned by wildfires have some of the hottest temperatures, an Associated Press analysis of fire and weather data found. As human-caused climate change has warmed the world over the past 35 years, the land consumed by flames has more than doubled.
WASHINGTON — Record heat returned to the United States with a vengeance in May.
May warmed to a record average 65.4 degrees in the Lower 48 states, breaking the high of 64.7 set in 1934, according to federal weather figures released Wednesday. May was 5.2 degrees above the 20th century’s average for the month.
