A new study finds that 50 percent of the freshwater required for soy and beef exports to the EU rely on river basins in Brazil with high or critical water scarcity.

A line graph shows the time series of global mean surface temperature anomalies for each May-June-July from 1850 through 2025. There is a long-term increasing trend and large year-to-year variability. The mean surface temperature anomaly in May-July 2025 was 1.03°C globally. Anomalies are computed relative to a 1901-2000 climate baseline. All data is from NOAA/NESDIS/NCEI NOAAGlobalTemp v6.0.0 on this graphic.

The average global temperature anomaly for every May-July period since the year 1850. As expected, 2025 will not set a new record for the annual mean metric.

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 June and September by looking at the decadal average line positions.

Monday ice update - #Arctic sea ice extent is currently the 11th lowest on record (JAXA data) 🧪🌊

• about 50,000 km² above the 2010s mean
• about 980,000 km² below the 2000s mean
• about 1,920,000 km² below the 1990s mean
• about 2,550,000 km² below the 1980s mean

Three Robinson projection maps showing 2-m air temperature anomalies in July 2025, May 2025 to July 2025, and August 2024 to July 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.

Polar stereographic map of sea surface temperature trends for Augusts from 1979 to 2024. Red shading is shown for warming trends, and blue shading is shown for cooling trends. All areas of the ocean are observing warming.

Quick look at August sea surface temperature trends across the #Arctic, which are warming nearly everywhere that sea ice is not found. We'll have an update on this in our next Arctic Report Card, which will be released in December 2025.

Last year's summary: arctic.noaa.gov/report-card/...

Polar stereographic map showing August precipitation trends over the period of 1979 to 2024. Nearly all areas are getting wetter across the Arctic in this month. Data is from GPCP.

Much of the #Arctic Ocean region is also getting wetter in the month of August, as estimated by GPCP. The largest trends are found in the Barents-Kara Seas region, which correlates with warmer SSTs and less sea ice.

Global map showing sea surface temperature anomalies in July 2025 relative to 1982 to 2010. Most areas are warmer than average. Red is shown for warmer sea surface temperatures, and blue is shown for colder sea surface temperatures. Data is from NOAA OISSTv2.1.

Woah, the hot spot across the northern Pacific is even more prominent in last month's sea surface temperature map. This is really quite striking! Though the extratropics in both hemispheres are warmer than average too.

Data from @noaa.gov OISSTv2.1 at www.ncei.noaa.gov/products/opt...

Last month was the 3rd lowest #Antarctic sea ice extent on record for the month of July.

This was 1,130,000 km² below the 1981-2010 July average. Data from the nsidc.org/data/seaice_...

North American bird declines are driven by reductions in common species Declines in North American birds are driven not by rare species vanishing but by sharp losses among formerly common species.

🚨 First PhD chapter is out! My work thus far, with @andy2dobson.bsky.social

We found that formerly common species have declined the fastest, on average.

Graph showing daily global mean near-surface air temperatures for 2025. This is also compared to the daily data from the 1971-2000 average, 1981-2010 average, and 1991-2020 average. Annotations are also shown to the current year with the other years from 1940 to 2024 and a threshold of 2°C above the 1850-1900 pre-industrial level. There is a strong seasonal cycle, with a peak during the boreal summer season. There is a long-term warming trend. 2024 is also indicated, which was the warmest year on record. Data is from ECMWF ERA5 reanalysis and updated through 29 July 2025

We are now at the climatological warmest time of year for the average global temperature. While there will be no new absolute records this year for the annual maximum, our planet remains much warmer than any previous decade in our records. 🤒

Four polar stereographic maps showing Antarctic near-surface air temperature anomalies for the month of July in 1985-1994, 1995-2004, 2005-2014, and 2015-2024. There is substantial regional variability.

A look at temperature departures for each of the last 4 decades across the #Antarctic. Lots of spatial variability by region this time of year.

Data from doi.org/10.24381/cds... and uses a 1951-1980 reference period for the anomalies.
