Krill fishery in Antarctica shut down after record catch triggers unprecedented early closure Officials have shut down the krill fishery near Antarctica early after exceeding the seasonal catch limit for the first time.

A record krill catch has led to an unprecedented early end to the fishing season for the shrimp-like crustacean critical to whales’ diets.

Despite a partial ban on heavy fuels oils enacted in 2024, black carbon emissions from Arctic shipping continue to grow. A new report now calls for urgent action by the IMO to curb the harmful particulates and switch to cleaner, less polluting fuels.

How do we actually know Antarctica is melting? Mass balance explained - British Antarctic Survey When news broke that Antarctica had gained ice mass between 2021 and 2023, it sparked debate across comment sections worldwide. How could the continent be gaining ice when we’re constantly …

Climate scientist Dr @michelle-maclennan.bsky.social from @bas.ac.uk explains how scientists measure ice changes across #Antarctica. What does "mass balance" actually mean? What are atmospheric rivers, and what part do they play in extreme events?

We've had a Very Important Ice delivery!

These precious ancient ice core samples from Antarctica are expected to reveal a climate record stretching back more than 1.5 million years 🤯

That's further than we've ever looked back before.

Trump’s budget takes aim at gold standard measurement of atmospheric carbon dioxide OPINION: “President Trump, a renowned climate change denier, has shown repeatedly that he has no use for scientific data that disproves his preconceived assumptions,” David Ho writes.

I wrote about the Keeling Curve — our most iconic CO₂ time series — for @sfchronicle.com.

"The Keeling Curve is valuable to science, but it is also a treasure that belongs to humanity as the most poignant indication of our impact on the environment and as a testament to our ability to document it."
