Department:June 21, 2017How do this year’s temperatures on the first day of summer compare to historical highs and lows? Compare your local conditions to these maps showing the warmest and coldest first days of summer for more than 4,000 U.S. locations.
Department:June 20, 2017The May temperature across global land and ocean surfaces was 1.49°F above the twentieth-century average of 58.6°F. Since 1880, May temperatures have been rising by 0.13°F (0.07°C) per decade.
Department:June 15, 2017Thanks to warming winters and thawing permafrost, Arctic soil microbes are churning out carbon dioxide well after the end of the growing season ends. This extra source of atmospheric carbon may accelerate a regional warming trend that is already twice as fast as the global average.
Department:June 6, 2017At the end of May 2017, central Florida was the only part of the contiguous United States experiencing extreme drought. These maps come from a new drought surveillance system that can detect vegetation stress without knowing anything about how much it has rained.
Department:May 31, 2017Between the weekly forecast and a seasonal outlook—and often less accurate than both—sit “sub-seasonal” weather predictions. In this profile, atmospheric scientist Libby Barnes talks about her work leading a NOAA task force whose members are trying to overcome the special challenges of forecasting over the 2-week to 2-month horizon.
Department:May 25, 2017NOAA's Climate Prediction Center releases its 2017 Atlantic hurricane outlook, saying odds favor an above-normal hurricane season.
Department:May 23, 2017A mild winter and warm spring have led to a large patch of open water in the Chukchi Sea off Alaska, an extremely unusual—possibly unprecedented—occurrence for mid-May.
Department:May 24, 2017Our ENSO blogger sits down with Ken Takahashi, an ENSO forecaster from Peru, to gab about the recent coastal El Niño and what might be coming up next.
Department:May 18, 2017According to NOAA's latest seasonal outlook, a hot summer is more likely than a cool one for most of the United States.
