Map depicting a CSI value of 5 for Phoenix, Arizona, on August 7, 2025, with dark red tones showing strong climate change influence. Phoenix reached a new all-time high of 118°F. An icon of intense sunlight reinforces the severity of the event, with the Climate Shift Index panel emphasizing that such an extreme temperature would be at least 5 times more likely due to climate change.

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.

Heat map-style graphic showing monthly air temperature rankings in the Arctic at the 925 hPa level for each month from January 1979 to July 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. July 2025 was the 9th warmest July on record.

Line graph time series showing global mean surface temperature anomalies for every March to May period from 1880 through 2023. A 30-year lowess smoothing line is also shown to reveal the trend. The March-May 2023 global mean surface temperature anomaly was 1.05°C. Anomalies are computed relative to a 1951-1980 baseline. The graph shows large interannual variability, but a long-term increasing trend, especially after 1980s. The dataset is from GISTEMPv4.
