Graph of the percent of annual runoff in the Sacramento River that comes between April and July, as snowmelt. This fraction has dropped from over 40% a century ago to just over 30% today -- a decline caused by climate change accelerating snowmelt earlier in the year. Graph plotted by Peter Gleick from CA Department of Water Resources data.
California's largest river, the Sacramento, is losing spring and summer runoff as climate change increases temperatures, changes snow to rain, and accelerates snowmelt in the winter months.

Serious stuff: “By 2100, global crop yields would be reduced by 11% if emissions rapidly plummet to net zero -- and by 24% if emissions continue to increased unchecked. In the shorter term, by 2050 climate change will decrease global crop yields by 8 percent”, regardless of scenario.

Damage is estimated at $1.2 billion, joining the U.S. ice storm/arctic onslaught over the past week as the first billion-dollar disasters of 2026. There were 55 billion-dollar weather disasters globally last year.

This winter blast is far from over. Washington, DC, is on track for its longest stretch below 32F in almost 40 years. Nearly 400,000 U.S. customers are without power. And snow could envelop NC's Outer Banks this weekend. @climateconnections.bsky.social

A green graphic with images of pine trees in the background. The DA logo is at the top. The text says “THE U.S. EXITS THE PARIS CLIMATE AGREEMENT This decision puts ideology over people, and short-term fossil fuel profits over our shared future. The Paris Agreement united nearly every nation on Earth around planet and our children.”
A light green background with the DA logo at the top with text saying “WHAT THE PARIS CLIMATE AGREEMENT HAS DELIVERED: REDUCE GLOBAL EMISSIONS GROWTH Since the Paris Agreement, global emissions growth has slowed significantly, as countries adopted cleaner energy and stronger climate policies. CREATED MILLIONS OF CLEAN ENERGY JOBS Climate action has fueled massive job growth, creating millions of stable, well-paying jobs in renewable energy, efficiency, and clean manufacturing. STRENGTHENED INTERNATIONAL COOPERATION The Paris Agreement united nearly every nation to share solutions, funding, and technology - accelerating climate action worldwide.”
A light green background with the DA logo at the top with text saying “WALKING AWAY HURTS AMERICANS. HIGHER CLIMATE DISASTER COSTS Climate disasters are already costing Americans hundreds of billions of dollars each year - and those costs rise when we delay climate action. LOST CLEAN-ENERGY JOBS The Trump regime has been busy decimating the US clean energy sector. This act cements that rollback and undermines U.S. global competitiveness in one of the fastest growing trade sectors. LESS GLOBAL INFLUENCE The U.S. now joins Iran, Libya, and Yemen as the only non parties to the Agreement. While the rest of the world steps forward our influence wavers - just look as Canada open its borders to Chinese, not American EVs.”
A dark green background with images of pine trees and the DA logo at the top. The text says “CLIMATE ACTION IS ON THE BALLOT From clean-energy jobs to disaster costs to global leadership - the choices we make at the ballot box shape our planet and our future. With primaries approaching, your vote matters more than ever. Vote for climate. Vote for science. Vote for our future.”
Today the United States formally exited the Paris Climate Agreement - again. Are you embarrassed? We sure are…
🔥 The planet is barreling through record heat, worsening disasters and mounting economic losses.
🗳️ Climate action is on the ballot. Go to votefromabroad.org.

The first images from MTG-S1's Infrared Sounder (IRS) were unveiled today at the #EuropeanSpaceConf, revealing storms, moisture flows and temperature patterns in striking detail - a preview of the near real-time weather and #climate data to come. (cont. 🧵)
In my newsletter this morning, I shared the experimental real-time freezing rain ice accumulation analysis developed by the winter weather research group at NSSL. This is the kind of R2O NOAA does that has clear societal benefit - and that the admin wants to curtail. tinyurl.com/43kcrhmb

Did you know that NOAA has a categorical ranking system (1-5) for winter storms?
It's called the Regional Snowfall Index (RSI): www.ncei.noaa.gov/access/monit...
Unlike the Saffir-Simpson or Enhanced Fujita scales, the RSI is attributed after an event and accounts for hazard AND societal impacts.

I summarized the biggest weather disasters of 2025 using last week's summaries from Gallagher Re and Aon. The costliest: $65 billion in damage from the L.A. wildfires. The deadliest: 24,000+ killed in the summer heatwave in Europe.
