Heat map-style graphic showing monthly air temperature rankings in the Arctic at the 925 hPa level for each month from January 1979 to September 2025. There is a long-term warming trend evident in each month. Blue shading is shown for colder months, and red shading is shown for warmer months. A yellow number is shown for each grid box to display the actual temperature ranking. September 2025 was the 7th warmest September on record.

Colleges see significant drop in international students as fall semester begins Delays and increased screenings for visas mean that many students didn't make it to campus on time – and that has some big implications for the economy.

Japan’s new seafloor monitors could reveal how β€˜slow slip’ earthquakes turn into big ones Network could add 20 minutes of tsunami warning at dangerous Nankai Trough

Japan has managed a huge accomplishment: fully covering the offshore parts of their subduction zones, which generate massive earthquakes and tsunamis, with more than 200 fiber-connected geophysical stations -- at a cost of hundreds of millions of dollars.

Nothing else in the world can compare.

Proposed NOAA budget zeros out ALL climate laboratories and cooperative institutions.

This appears to also end the US greenhouse gas sampling network, including at Mauna Loa, the oldest continuous carbon dioxide monitoring site on Earth.

Temporal evolution of the GJES: (a) Rate and cumulative number of earthquakes from TM detection. (b) Seismicity timeline: Moment magnitudes of TM detections color-coded by template association. (c) Statistical analysis I: Diurnalized a-value (i.e., normalized to reflect a rate based on a 24-hour reference period) and b-value of TM detections larger MC=MW0.7.

I don't want to say this was completely unexpected, because this is something changes in ice coverage can affect, but increasing seismic hazards is not the first impact of climate change that comes to mind. πŸ§ͺ

This graphic shows four line graph time series and each are monthly from January 1984 through May 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 431 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.

New research shows that 1 million years ago, a shift in ocean winds changed Southern Africa’s rainfall patterns. This ancient change could help us understand future water risks from climate change.
