Line graph time series of 2025's daily global sea ice extent in red shading compared to each year from 1979 to 2024 using shades of purple to white for each line. There is substantial interannual and daily variability. Seasonal cycles are visible. Note: the poles are affected by very different Earth system processes/seasonality. I am using 5-day running mean data.
While all of this is happening to our scientific agencies, the current extent of sea ice globally remains at record low levels...

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.
Sunday ice update - #Arctic sea ice extent is currently the lowest on record (JAXA data)
• about 740,000 km² below the 2010s mean
• about 1,340,000 km² below the 2000s mean
• about 1,720,000 km² below the 1990s mean
• about 2,260,000 km² below the 1980s mean

December-February 2024-25 temperature ranking since 1895-96 according to Prism climate data. Globally, this was the 2nd warmest Dec-Feb period, but the Contiguous U.S. was the outlier. Congrats!

This is very concerning.

Another paper showing climate shocks lead to support for climate action among conservatives. Analyzing data collected in Florida, the paper finds Republican positions change after personally experiencing loss from climate-exacerbated extreme events.

Three orthographic maps showing 2-m air temperature anomalies in January 2025, November 2024 to January 2025, and February 2024 to January 2025 in the Arctic region. Red shading is shown for warmer anomalies, and blue shading is shown for colder anomalies. Most areas are warmer than average. The mean temperature anomaly for each map is also displayed. Anomalies are calculated relative to a 1981-2010 baseline.
Looking at temperature anomalies over the last month (left), 3 months (center), and 12 months (right) across the #Arctic...

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. Additional scatter points show the maximum extents from 2000 to 2024. There is a long-term decreasing trend in ice extent for every day of the year.
Ice Watch - Time to start tracking the annual maximum #Arctic sea ice extent. A new record is definitely possible this winter. Stay tuned.

A trifecta of fire-friendly climate conditions fueled the January 2025 fires around Los Angeles: back-to-back wet winters that boosted vegetation, a record-dry fall, and extremely strong Santa Ana winds. See the map for how drought helped set the stage.

Global map showing surface air temperature anomalies for the November 2025 to January 2025 period across the entire planet. Most all areas were warmer than average, especially in the Arctic. This data set is from NOAA's NOAAGlobalTempv6.0.0 using anomalies with a 1971-2000 climate baseline. Red is shown for warmer than average temperatures, and blue is shown for colder than average temperatures.
Looking back at temperatures averaged over the last 3 months - find your location...

4/ 🛠️ Why does this matter?
➡️ Changing pest distributions impact forest health & management
➡️ Increased defoliation risks in new areas
➡️ Need for proactive strategies to reduce vulnerability
3/ 🌎 Most importantly, climate change is a bigger driver of SBW dynamics than landscape changes!
This means forest ecosystems are being reshaped faster than we expected, requiring adaptive management strategies.
2/ 📈 Key findings (1950–2022):
📍 +68 km northward shift of suitable climate conditions (up to 200 km in some areas!)
⏳ Earlier phenological events & higher reproduction rates in the north
❄️ Increased winter mortality in the south due to warmer temperatures
1/ 🌲🔬 New Research Alert! 🌡️🦋
#ClimateChange is reshaping forest ecosystems, and the spruce budworm (Choristoneura fumiferana), a major boreal forest defoliator, is feeling the heat! 🔥

• about 2,010,000 km² below the 1990s mean

Graphic showing a line graph time series of daily Arctic sea ice extent in the Pacific sector of the Arctic (Bering Sea and Sea of Okhotsk) for each year from 1979 to 2024. This year is shown in red. Purple to white color shading is used for each other year's line. There is a long-term decreasing trend for every day of the year.
Graphic showing a line graph time series of daily Arctic sea ice extent in the Atlantic sector of the Arctic (Greenland + Barents + Kara Seas) for each year from 1979 to 2024. This year is shown in red. Purple to white color shading is used for each other year's line. There is a long-term decreasing trend for every day of the year.
Sometimes it is only one side of the #Arctic that experiences anomalously low conditions during winter, but this year we are seeing the sea ice edge on *both* the Atlantic & Pacific sectors at very low levels for this time of year. This is contributing to the historic record low for early February.
