Given what seems to be disappointing news from COP30 I can’t see the rate of temperature increase lowering any time soon
rarohde.bsky.social Robert Rohde @rarohde.bsky.social · 15d
2025 is expected to conclude as the 3rd warmest year to have been directly measured.

This would place 2025 behind only the El Niño boosted record warmth in 2023 and 2024, and still modestly above the long-term trend.

Always amazed at global temperature ups and downs. We are relatively down at the moment but 2025 still on track for third place slot.

World’s surface temperature a little on the cool side (relatively). Still 2025 is heading for third place

What’s going on with global warming ? Where can I find a monthly update of global temperatures ?
Here of course berkeleyearth.org/september-20...
September 2025 Temperature Update - Berkeley Earth
September 2025 was the 3rd warmest September on record, and 2025 is likely to become the third warmest year on record. A La Niña transition appears imminent.

Keeping an eye on our planet's recent temperature trend and variability (12-month running mean). Many of the temporary peaks and dips are related to upper ocean heat anomalies in the Pacific (like ENSO).

Line graph time series of a 12-month running mean of global mean surface temperature anomalies from 1979 through September 2025. There is a long-term increasing trend and large interannual variability on this graph. Anomalies are computed relative to a 1991-2020 baseline. Blue shading is shown for below average anomalies, and red shading is shown for above average anomalies.

Our oceans are warming. Here is a look at the globally averaged sea surface temperature over the last three months relative to each May-June-July period since 1854.

Data from NOAA ERSSTv5: www.ncei.noaa.gov/products/ext... 🌊
Green line graph time series of average sea surface temperature anomalies for each May-July from 1854 through 2025. There is large interannual variability, but an overall long-term increasing trend. Anomalies are computed relative to a 1981-2010 baseline. 2025 is the 3rd warmest on record.

It seems that the lurch upwards in global temps late 2023 may have originated in the switch from a prolonged La Niña to El Niño affecting cloud cover changes @michaelemann.bsky.social @hausfath.bsky.social

My only wish would be that global temperature anomalies reference 1850 - 1900 but otherwise excellent

It's time for your monthly climate change update: 🫣

+ Global temperature: 📈
+ Carbon dioxide (CO₂): 📈
+ Methane (CH₄): 📈
+ Nitrous oxide (N₂O): 📈

Graphic by zacklabe.com/climate-chan...
This graphic shows four line graph time series and each are monthly from January 1984 through June 2025. The first graph is a 12-month running mean of global mean surface temperature anomalies. Anomalies are computed relative to a 1991-2020 baseline using ERA5 data. The second graph is monthly carbon dioxide abundance. The CO2 graph is the Keeling Curve. Current levels are 430 ppm. The third graph is monthly global methane abundance. Current levels are 1934 ppb. The fourth graph is monthly global nitrous oxide abundance. Current levels are 339 ppb. The three greenhouse gases show seasonal cycles and long-term increasing trends using data from NOAA ESRL. The global mean surface temperature anomaly record also exhibits decadal variability and a long-term increasing trend. All graphs are rising and shown in four different colors, including white, yellow, orange, and pink.

Looking at Climate Pulse, it seems that 2025 is heading for third place with a chance of second. But this is with El Niño neutral conditions
