Sometimes a volunteer. A work in progress, according to Ethel. Amplifying climate info that catches my eye.

A first year above 2C in the mid-2030s now looks plausible. 0.5C was first passed in 1980, 1.0C in 2010 and 1.5C in 2024. The 15-year trend runs at 0.42C per decade. The 2026 and 2027 points for the current El Nino are estimates. We're not remotely ready!

Line chart titled "A first year above 2 C in the mid-2030s looks increasingly plausible". It shows global mean surface temperature from 1940 to 2050 as the annual anomaly against the 1850 to 1900 baseline, in degrees C. Data is ERA5 from Copernicus, running to 31 July 2026. A thin gold line shows individual years, wobbling around a thick dark blue smoothed trend. Both sit near 0.2 C through the 1940s to the early 1970s, then climb steadily from the mid-1970s onward. Three red dots mark the first year each threshold was passed. 0.5 C in 1980, 1.0 C in 2010 and 1.5 C in 2024. Labels beneath note the gap of 30 years between the first two and 14 years between the second and third. Everything above 1.5 C is shaded pink. Two dashed lines run forward from 2025. A blue line follows the 15-year trend of 0.42 C per decade and reaches 2 C in 2037. A fainter grey line follows the 30-year trend of 0.27 C per decade and reaches 2 C in 2044. Two orange circles mark estimates for the developing El Niño, at about 1.5 C for 2026 and about 1.7 C for 2027.

Global mean sea surface temperature anomalies (departure from average) so far this year ➡️ 2nd highest on record 🌊 Data from ERSSTv5 averaged over January to June.

Green line graph time series of average sea surface temperature anomalies for each January to June period from 1900 through 2026. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline.

Breaking News! Code Yikes! The latest CERES data for March just dropped and the planet is now at its fastest rate of heating since January, 2024. Over the last 12 months Earth warmed at a rate of about 13.16 Hiroshimas per second, or about 1.14 million Hiroshimas per day.

Breaking News! Code Yikes! May 21st saw yet another daily record for the global sea surface temperature, with El Nino just getting started. And the other 3 lines in that snapshot? 2023, 2024 and 2025.
