☆ The upcoming solar eclipse will cause shallow, cumulus clouds to disappear. Researchers explain why
▼ + stars: | 2024-03-30 | by ( Ayurella Horn-Muller | ) edition.cnn.com time to read: +11 min

That’s at least what scientists expect to take place in swaths of Mexico, Canada and the United States during April 8’s total solar eclipse. They discovered that cumulus clouds dissipate during eclipses because of the relationship between solar radiation and the formation processes of the clouds. Shallow cumulus clouds, in particular, serve a critical function. But what exactly shallow cumulus clouds’ role is when it comes to the rapidly warming climate remains a long-standing subject of uncertainty in the scientific community. De Roode hopes those across North America gearing up for the next solar eclipse remember to keep an eye out for any vanishing low-lying cumulus clouds.

When Daniel Skousen scrubs at the ash and soot covering his Maui home, he worries about the smell. Crews have installed air quality monitors throughout town and are spraying a soil sealant to prevent toxic ash from being washed into the ocean or blowing around. The Hawaii Department of Health's Environmental Health Services Division also told Skousen's attorney it had no records about residential testing of contaminants to release. “If it smells like burned plastic or burned electrical cables, then probably those chemicals are in the air and not healthy,” Hertz-Picciotto said. Whether a home can be made safe enough for residency comes down in part to the resident's risk tolerance, Hayes said.

Satellite imagery from Aug. 27 showing blue lighting strikes inside Tropical Storm Idalia has been shared on social media alongside false claims that they are evidence of laser attacks or Direct Energy Weapons (DEW). We are being terrorized on the daily.”The video does show lightning during Idalia and not man-made lasers or weapons. Examples of previous satellite imagery by CIRA depicting lighting artificially colored in blue amid tropical storms are viewable (here), (here), (here). Reuters previously addressed false claims of lasers or direct energy weapons, or DEWs, causing extreme weather events (here), (here) and explosions (here). The blue lighting strikes viewable in the satellite imagery are a result of false color used by weather mapping organizations for visibility purposes.

Here are some of the notable weather phenomena striking the United States on Wednesday:HEATWAVE BREAKS ARIZONA RECORDA massive heat dome parked over the southern and western United States is keeping tens of millions of Americans under extreme heat advisories. Central Texas, an area stretching from San Antonio north to Dallas, is forecast to reach 105 degrees or higher over the next two days. The all-time high for Death Valley is 134 degrees, which is also the hottest temperature ever recorded on the Earth's surface. "If you have the right kind of weather pattern, you can get this transport of the smoke," Benjamin said. TROPICAL STORMS AND FLOODSHawaii's Big Island was under a tropical storm warning early Tuesday morning as it braced for Tropical Storm Calvin, expected to bring as much as 8 inches of rain and wind gusts of 40 mph, the National Weather Service (NWS) said.

☆ Antarctic sea ice has been at record low levels for months — here's what that means

Xinhua News Agency | Xinhua News Agency | Getty ImagesAntarctic sea ice has been at record low levels for the past few months. What the record low sea ice in the Antarctic meansZoom In Icon Arrows pointing outwards The blue line sows the amount of sea ice in the Antarctic in 2023. Why the sea ice levels in the Arctic are more damningThe Arctic is an ocean covered by a layer of sea ice and surrounded by land. So the change below the surface in the Arctic sea ice is much more pronounced than the change in Antarctic sea ice," Meier told CNBC. While the sea ice does not directly contribute to sea level rise, melting land ice does.

☆ The world’s largest lakes are shrinking dramatically and scientists say they have figured out why

Lake water levels fluctuate in response to natural climate variations in rain and snowfall, but they are increasingly affected by human actions. The Caspian Sea, between Asia and Europe – the world’s largest inland body of water – has long been declining due to climate change and water use. NASA NASA The Caspian Sea is rapidly shrinking due to climate change and human activity. NASAThe researchers used satellite measurements of nearly 2,000 of the world’s largest lakes and reservoirs, which together represent 95% of Earth’s total lake water storage. The report found losses in lake water storage everywhere, including in the humid tropics and the cold Arctic.
