$101 Billion: First Six Months of 2025 Set New Record for Global Warming Damages:
New data from over 1,000 rivers shows extreme waterway heating events last twice as long as they do atmospherically
New study shows US rivers warming at a record rate
The first in-depth study of river heat waves shows that inland marine heat waves are quickly getting which are worse as the planet heats up
A new 40 year Penn State analysis of nearly 1,500 rivers found that the frequency, intensity and duration of heat waves is increasing in streams, rivers and creeks around the US. Among the more immediate effects is the threat to trout, salmon and other species that are adapted to cooler temperatures. Heat decreases the amount of dissolved oxygen in water. Meanwhile, cold-water species often see their metabolism rise in warmer waters, meaning there’s less oxygen available.
The new analysis was published in the peer-reviewed journal Proceedings of the National Academy of Sciences.
The authors found that human-caused climate change is the primary driver of the trend, as snowpack dwindles and streams flow more slowly.
Other human factors such as dams and hard surface infrastructure also drive water temperatures higher.

Invasive Weed Canada
As global warming accelerates, hundreds of species of flora and fauna are moving North into new biomes. Some are obvious, some are not. In Canada, the pernicious kochia was previously confined to the southern prairies, but is now rapidly spreading.
107.2ºF Japan Record Heat
Summer 2025 was the hottest ever recorded in Japan, with the nationwide average 4ºF hotter than average since records began in 1898. The central city of Isesaki set a new national record high of 107.2F August 5, 2025.
Hot Marine Blob Is Back To Stay
A massive heat wave continued to grow the off the Pacific coast. Water temperatures several degrees above normal now span thousands of miles across the marine region. Beyond disrupting the ocean’s food web and fisheries, the “Blob” alters weather on land.
Massive Mexico Floods Kill 100s
Hundreds have died and more remain missing after a week of cataclysmic downpours triggered severe flooding and landslides across several Mexican states. Overflowing rivers swept through entire villages, triggered landslides and swept away roads and bridges..
