Every winter, folks that are either biased or not paying attention to science claim the cold is evidence that there is no global warming, when in fact cold is just evidence of winter. In fact, climate change can make the cold more extreme.

Winter storm doesn't disprove climate change, despite Trump's claim. Scientists explain why.

Climate adaptation at work. Note that many adaptation options could be overwhelmed if climate change isn't slowed/halted. Adaptation isn't always feasible or affordable as well. Still it's important and valuable.

The new administration has knee-capped the formerly rapidly growing U.S. clean energy manufacturing buildout, handing this sector to China and other countries. A big loss for our economy.

Chart: Trump cratered the clean-energy manufacturing boom
In 2025, companies spent less on U.S. factories for solar panels, EVs, and more. A bonus chart shows why this trend may continue in the year to come.

We're getting more wildfire - lots more - due to climate change, and that means more smoke too. Wildfire smoke is toxic in many ways, and here's new evidence that it is important to avoid smoke during pregnancy.

Exposure to wildfire smoke late in pregnancy may raise autism risk in children
Exposure to wildfire smoke during the final months of pregnancy may raise the risk that a child is later diagnosed with autism, according to a new study led by Tulane University researchers.
