Earthrise to Earthset: how the planet’s climate has changed since the photo that inspired the environmental movement The global climate has changed drastically over the course of the 58 years that separate these two photographs of planet Earth.

Nice article from Nick on the perspective offered by two Earth photos!

Marine heatwaves can supercharge cyclones Storms that cross exceptionally warm ocean waters intensify more quickly and do more damage than storms that do not.

One of my former students took her final project for my field natural history class and turned it into her Honors thesis: a 100% original, hand-drawn field guide to the rocky intertidal! And she got copies printed for her defense!

Moderate global warming does not rule out extreme global climate outcomes - Nature Extreme global climate outcomes may occur even under moderate 2 °C warming and may turn out to be more extreme than model-averaged projections at 3 °C or 4 °C warming.

In a new Nature study, we show that extreme global climate outcomes may occur even under moderate 2°C warming for several sectors.

The findings reinforce the urgency of limiting warming well below 2°C.

Climate has almost disappeared from our conversation.

But it remains the most pressing challenge of our times.

Last week the WMO said the planet is “more out of balance than at any time in observed history.”

Energy security and climate security are not competing priorities.

NASA revives next-generation flagship Earth-observing missions “Falcon” and “Eagle” will monitor changing clouds and map critical minerals

ICYMI, some good news from @science.org: NASA has revived its next-generation satellite missions, which will study changing clouds and rainfall and use hyperspectral imagery to chart ecosystems, critical minerals, and greenhouse gases.

These are big climate missions, even if NASA can't say that.

Administration Targeted Climate Lab in Effort to Free Trump Ally, Lawsuit Claims

Trump is trying to shut down one of the world's premier climate & weather research labs. Why?

A petty beef with a Colorado official who didn't support his effort to steal the election. That's it.

Map of the lower 48 United States showing 0.25° GFS run from 18z on 20 March 2026. The variable is the 500 hPa geopotential height percentile rank considering ERA5. There is a record-breaking ridge across the Western U.S.

Honestly, this historic heat dome across the West is really hard to put into words for me. Temperatures over 110°F (43°C) in March, shattering all-time monthly records on multiple consecutive days, and not just by a little.

➡️ I can confirm this is human-caused climate change.

This is the hall where the Kyoto Protocol was signed. It’s impossible not to feel the weight of history and the juxtaposition to current anti-science sentiment. Last week’s CMIP meeting lived up to that legacy—well-organized & rigorous. Perfect blend of historic significance and vision. #CMIP2026

Have you noticed synchronized SST anomalies between the Pacific and Atlantic in global maps? It’s not a coincidence. According to a new study in Science Advances by Joh et al. (2026), this "oceanic handshake" is directly linked to the retreat of Arctic sea ice. 🌊🧪 ocean2climate.org/2026/03/01/t...
