Deadly rivers in the sky A new Washington Post investigation reveals where climate change has supercharged the movement of moisture through the skies.

Gift Article!

A great article! Well-researched and written, with an excellent animation that makes climate change and the associated increase in atmospheric water vapor much easier to understand!

"The water vapor in Earth's atmosphere has increased by 12 % in the last 85 years.β€œ

"Health losses attributed to anthropogenic climate change," a brief communication in the journal Nature Climate Change. There's a map showing regions of the world, and pie charts of relevant studies as they apply to different health impacts like "heat-related deaths" and "maternal and child health"

🚨 NEW: Climate change is already causing 30,000 deaths per year - a global annual economic loss of $100-350B USD - but the true damage is probably 10x higher.

Updating Mental Models of Risk Disasters are no longer isolated events. This demands a fundamental change in how we think about and respond to complex risk.

To understand modern risk, we have to grapple with emergent and novel aspects of hazard, vulnerability, exposure, and response that comprise risk.

Ice breaking capabilities are essential to support critical research on the Antarctic ice sheet and its response to climate change. This reversal of decades of US leadership in polar research is shortsighted and counterproductive.

Hurricane Erin achieved something most storms do not this weekend. "Extreme Rapid Intensification". Did climate change play a part? Science says, yes.
In 12 hours winds increased by ~65 mph. Only 3 other storms have done that and Erin was the earliest & only August storm to do so.

There are 2 previous historical cases of countries destroying their science and universities, crippling them for decades: Lysenkoism in the USSR and Nazi Germany. The Trump administration will be the 3rd.
It's not just budgets but research, institutions, expertise, and training the next generation.

Oh no! Several of the Regional Climate Centers have had their funding lapse through DOC/NOAA. These institutes are critical for connecting weather and climate data and services to local communities across the United States.
