Utility-scale battery storage costs have dropped more than 50% since 2022. That cost curve is now enabling large-scale “always-on” renewable systems that combine solar, wind and storage to deliver power day and night-demonstrated in Australia and UAE. www.linkedin.com/posts/janros...

Weather unfollowed is a danger to all Americans. NOAA faces proposed budget reductions of about $2 billion, and one proposal would eliminate NOAA's Office of Oceanic and Atmospheric Research entirely, shutting down all research laboratories across the country.

I just turned off heating last night, but it appears I would have to turn on AC starting from tomorrow, if not today. There is literally no spring up here this year.

1/1 The GCP-Global Carbon Budget 2025 has just been published in its final form. It is the same data we released at the last COP in Nov 2025, but given the many improvements this budget introduced compared to previous editions, it underwent a longer and more detailed peer review process.

The much-awaited FLUXNET Shuttle is here. A new system for accessing eddy covariance data that captures how carbon, energy, and water are exchanged between the land surface and the atmosphere. (more at the following blog by @fluxnet.bsky.social ) fluxnet.org/2026/05/14/f...

The latest global temperature data from Copernicus has the planet at a record daily high on May 13th, likely the hottest May 13th in the last 120,000+ years. And El Nino is just getting started. We live in interesting times.

New @unep.org working paper on Solar Radiation Modification concludes... "The current state of scientific knowledge does not support SRM as a viable response to #climate change as it does not address the root cause of the current anthropogenic climate change."

Costa Rica passed a law in 2018 that required electric utilities to install fast chargers every 50 miles on national highways. Tax breaks have made Costa Rica a pioneer in electric vehicles. Costa Ricans are buying electric vehicles at 3 times the rate of Americans. www.nytimes.com/2026/05/03/b...

Amazing graphic of US drought crisis, reaching beyond “extreme” into “exceptional.” New levels of extreme weather from fossil fuel pollution.

This is cool. I’ve never seen one before.

Europe has made remarkable progress cleaning up its electricity. In 2024, just 29% of European electricity came from fossil fuels - down from 53% in 2005. But electricity is only 23% of Europe's total energy use. Look at other sectors & it changes dramatically. More here: substack.com/@janrosenow

Norway sold 12 petrol cars in February 2026. Out of 7,272 new passenger car registrations, 98% were fully electric. Just 67 diesel & 12 petrol cars were registered. Hybrids? Only 66 in total mostly plug ins. More in my new Substack newsletter coming out every 7 days. Sign up here: t.co/In5lBaF2ox

2024 wasn’t just the hottest year on record. It also saw the fastest rise in atmospheric CO₂ ever observed. A new study in @NatureComms shows a sharp drop in the land carbon sink, driven by a surge in ecosystem respiration under hot+wet extremes, despite enhanced GPP. www.nature.com/articles/s41...

Denmark's coal-to-wind transition is one of the most dramatic energy transformations of the past three decades. In 1990, coal provided 90% of Danish electricity. Today it is under 3%. Wind now covers roughly 60% of electricity generation. The last coal plant is scheduled to close by 2028.

Not getting a ton of attention, but wildfires in GA/FL have now destroyed 120 structures in the midst of heavy drought conditions 🎁 Wildfires Destroy Dozens of Structures in Georgia, Governor Says www.nytimes.com/2026/04/24/u...

It's April 19 and Illinois has already had 65 confirmed tornadoes this year. That number is expected to grow as experts still assess what went down on Friday. That is an absurd number for this early.

"Under worst-case warming scenarios (∼3.6°C), 40.7% ± 1.0% of the global population could experience heightened compound hot-dry extremes" Cai et al. 2026 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Hopefully this is a milestone in the U.S. energy transition.

Together, renewables — including solar, wind, hydropower, and bioenergy — were the biggest source of U.S. electricity in March, according to data from the think tank Ember. Along with nuclear power, they supplied more than half of U.S. power.

What drives tree growth after a hurricane? 🌀🌳 Hot off the press in @pnas.org today! We tracked 1,082 trees in Puerto Rico and found that pre-disturbance growth outperformed crown biomass loss and competitive release as a predictor of post-storm growth. The paper: www.pnas.org/doi/10.1073/...

These countries are great role models.

Our burning of fossil fuels is melting sea ice and drowning emperor penguin chicks, putting them in danger of extinction. 😱

If this trend continues, drought might become the new norm.

The contiguous U.S. averaged precipitation total for 2026 to date is an ominous one: a mere 4.79". That’s the lowest value on record for any January-to-March interval, including such notoriously dry periods as the Dust Bowl of the 1930s. The previous record low was 5.27", set in Jan.-Mar. 1910.

The white snow, begrudging spring for arriving too late, flutters through the courtyard trees, pretending to be blossoms.

The plot also illustrates how plant growth and seasonal dynamics affect the seasonal patterns of CO2 concentrations across latitudes.

American shad might migrate up here earlier this year, too.

In 2025, wind and solar generated more EU electricity than fossil fuels for the first time ever, marking what experts described as a “major milestone” in the transition to clean power. 👍 www.euronews.com/2026/04/01/s...

The Amazon rainforest was hit with two severe droughts during 2023–2024. Models suggest that just over half the forest will not recover within seven years, which is the maximum time between droughts in recent decades. In PNAS: https://ow.ly/BKQ150YySOw
