The ocean absorbs excess human emitted CO₂ from the atmosphere, and through a series of reactions, decreases seawater pH in a process known as #OceanAcidification. #OADayofAction 🧪🌊🦑

2025 goes down as the ~3rd-warmest year on record (based on ERA5).
Like in 2024, every single day this past year was warmer than the average of even the most recent reference period (1991-2020).

🚨 The first preliminary analysis from the Japan Meteorological Agency highlights 2025 as the third warmest year on record globally (since at least 1891 in this data).
Additional climate rankings will be released later for other datasets.

Pulling climate data offline, canceling research grants, and de-funding scientific institutions doesn't just suppress climate information. It weakens the foundation we rely on to make good decisions of any kind.

This is NGC 2264, also called the "Christmas Tree Cluster." It's a cluster of young stars about 2,500 light years away.
They were 'born' during the Pliocene Epoch (2-5 MYA), about the same time as early hominids like Ardipithecus or Homo habilis, so they're barely older than humanity.

I look forward to the legally required, transparent peer review process required by the US Global Change Research Act and the Information Quality Act. I always thought they would try to do a NCA with Judith Curry, five old men and a LLM.
It’s the gold standard of US climate research. Contrarians could write the next one.
