{"chart":{"slug":"warming-by-state","title":"Which US states have warmed the most?","takeaway":"In the 10 years through 2025, Alaska was among the states that warmed most, averaging 3.3°F warmer than in 1901–2000, while Oklahoma was among those that warmed least, 1.6°F; the contiguous US warmed 2.2°F. Alaska's records start in 1925, so its baseline is 1925–2000.
