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.

U.S. dams, levees, stormwater, and wastewater systems get D to D+ grades, need almost $1 trillion in upgrades » Yale Climate Connections
Climate change is increasingly stressing dams, levees, wastewater, and stormwater systems through heavier precipitation events.

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
