Poor bunnies...their phenology is completely mismatched this year because there is no snow anywhere. I hope they don't get wiped out by predators! Come on snow!

While the entire weather enterprise - it seems - is focused on extreme US cold - which may take weeks to materialize, the country has been roasting. Over the past 7 days 100s of heat records have been broken, and the nation as a whole has been ~4F above normal. +20F near the Ark-La-Tx!!

We have a tendency in weather to focus on the shiny object. Right now that shiny object is the cold, which is elusive.
The reality: over the past week, the US has seen a Blow Torch. 100s of heat records to just a dozen cold. The heat continues through midweek.

Some people ask me, why track record temperatures? More heat does not affect me, so why should I care? Because record warmth is a big symptom of the climate's health over the last few decades, giving us warning of what may come. Heed the drip drip drip coming into the Titanic. @katharinehayhoe.com

Many people don't realise how climate change is already - not in the future - affecting our lives. And it's doing so in ways that, once our eyes are opened, we can notice!

For example, food. h/t @climatecentral.org
A bar chart showing how climate-related extremes spiked the costs of cocoa, vegetables, coffee, and more. An infographic showing how heat, flood and drought affect all aspects of the food supply chain.

My last research project showed that many mammals now live in climates different from the ones they occupied for thousands of years.

Publishing it made me realize how often important science stays inaccessible
and why I now focus on sharing it clearly.

Concerning: for a high emissions scenario, the model found a 37% increase in daily extreme precipitation over land by 2100. “Much of the increase was driven by shifts in wind patterns that created chains of severe thunderstorms hundreds of kilometers long that traditional models fail to capture.”
voosen.me Paul Voosen @voosen.me · 3d
My latest for @science.org: A remarkable set of high-resolution climate model runs, computed over 900 (!) days of supercomputing time, are revealing how warming-induced changes to Earth's wind patterns due can prime huge spikes in extreme rainfall.

But the MESACLIP runs also do much more than that.
High-resolution climate model forecasts a wet, turbulent future
With details as fine as short-term weather forecasts, model achieves newfound accuracy

Expect this list to grow: Three of the top 5 deadliest heat waves in world history have been in Europe in the past five years. "Mitigating further global warming can reduce heat mortality, but mass mortality events remain plausible at near-future temperatures despite current adaptations to heat."

The amount of solar-power capacity installed by China in Q1/Q2 2025 alone (256 gigawatts, ~ roughly 200 big coal plants) matches *all* the cumulative U.S. solar-power capacity installed thru Q2 2025 (260 gigawatts). We are watching the world leap past us.
