Carbon dioxide (CO₂) averaged about 426 ppm in November 2025

10 years ago November averaged about 400 ppm

Data available at gml.noaa.gov/ccgg/trends/
Red line graph time series of monthly carbon dioxide abundance from January 1959 through November 2025. There is a seasonal cycle and long-term increasing trend. Current levels of CO2 are at 426 ppm. This is the Keeling Curve graph. A line for CO2 10 years ago is also annotated.

It's not every day that both poles set new monthly temperature records (see my earlier post). Last month also observed the warmest October on record for the #Arctic Circle. Not great!!

Data provided by doi.org/10.24381/cds....
Line graph time series of 2-m air temperature anomalies for the Arctic in every October from 1979 to 2025. There is a long-term warming trend, and 2025 is the warmest on record in this time series. Data is from ERA5 with a 1981-2010 climate baseline used for calculating the anomalies.

Temperatures were warmer than 5°C above the 1981-2010 average in September 2025 across northern Canada and into the Canadian Arctic Archipelago. The southern route of the Northwest Passage was ice-free and open for transit this past melt season.

This is the second largest May-May increase in this dataset (3.6 ppm higher than 2024). This is not good... 🫣

Carbon dioxide (CO₂) averaged nearly 430 ppm in April 2025 (new record high)

10 years ago April averaged about 404 ppm. Preliminary data from gml.noaa.gov/ccgg/trends/...

This isn't going away. The longer we wait to address climate change, the greater the impacts and the harder it becomes to solve

My climate change dashboard is updated for this month...

Higher resolution graphic available at zacklabe.com/climate-chan... 🧪⚒️
This graphic shows four line graph time series and each are monthly from January 1984 through March 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 428 ppm. The third graph is monthly global methane abundance. Current levels are 1938 ppb. The fourth graph is monthly global nitrous oxide abundance. Current levels are 338 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.

Last month was the 2nd warmest March on record globally (after last year). Some of the largest warm departures were found over Baffin Bay and eastern Europe. The USA was quite warm as well.

Less sea ice compared to average could be found around almost the entire #Arctic sea ice edge during March 2025, which contributed to its record low total ice extent.

I'm predicting that the Mauna Loa CO2 average for March, 2025 will be 428.15 ± 0.01 ppm, a jump of 2.77 ppm from March, 2024.

Stay tuned.

The global mean surface air temperature anomaly (departure from average) so far this year now placed in historical context.

Data from NOAAGlobalTemp v6.0.0 averaged over January to February.
Line graph time series of global mean surface temperature anomalies for each January-February period from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly averaged for January-February 2025 was 1.29°C for the global mean. Anomalies are computed relative to a 1901-2000 climate baseline.

Looking at temperature departures over the last month (left), 3 months (center), and 12 months (right) around the world.

Now is definitely not the time to stop researching and talking about "climate"

Data for the maps available at: doi.org/10.24381/cds...
Three Robinson projection maps showing 2-m air temperature anomalies in February 2025, December 2024 to February 2025, and March 2024 to February 2025 across the globe. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. Most areas are warmer than average. The mean global near-surface air temperature anomaly for each map is also displayed in the upper-left corner. Anomalies are calculated relative to a 1981-2010 baseline. Data is from ERA5 reanalysis using the 2-m air temperature variable.

Now looking at a spatial view of temperature anomalies during the December to February 2025 period again highlights the relative Arctic warmth and lack of cold departures to be found anywhere outside of the central Pacific.

Preliminary data suggests that the global average increase in atmospheric CO2 concentration in 2024 will be a record.

Not just a little record, but 25% higher than the previous record.

(This is the global average, as opposed to Moana Loa)
