Enlarge / Hurricane damage in Puerto Rico. With the warming climate, we should expect a change in weather-related disasters. Fewer cold snaps and stronger heat waves are the obvious issues. But we should also see more intense storms, as a warmer atmosphere can hold more water vapor, while droughts may intensify in areas where rain…

Why lightning strikes two times as frequently over shipping lanes

For all the progress humanity has made since Odysseus had a spot of trouble on a long voyage home, life on the high seas remains a largely joyless affair. Twenty-first-century sailors spend weeks away from home. The hours are long, the pay mediocre, the risk of calamity never quite over the horizon. And, researchers have…

Ted Shaffrey/AP A group of protesters mounted Wall Street's famous "Charging Bull" statue and poured fake blood on it as part of a Monday "die-in" demonstration. The protest was organized by climate activism organization Extinction Rebellion, according to CNBC. Protesters lay around the bull with red paint on their bodies while one member waved a…

Environment stakes are high for ice and oceans, IPCC report describes

"Over the 21st century, the ocean is projected to transition to unprecedented conditions with increased temperatures, greater upper-ocean stratification, further acidification, oxygen decline, and altered net primary production." That's one of the top-line conclusions detailed in a new IPCC report released Wednesday. This latest report—the volunteer work of over 100 scientists summarizing almost 7,000 published…

Burning fossil fuels spews carbon dioxide into the air, which warms the climate through the greenhouse effect (as if you didn’t know that). But burning fossil fuels also spews sulfur dioxide into the air, and sulfur dioxide forms aerosols that can deflect the sun’s rays and thus cool the climate. It has thus been argued…

Enlarge / Temperatures during the third week of July, 2019. Long-lived heatwaves in the mid-latitudes are typically the result of an atmospheric pattern known as a “blocking high.” In a blocking high, the jet stream bends in a north-pointing ridge (in the Northern Hemisphere, anyway), creating an area of high atmospheric pressure as long as…
