  July 2026 was the warmest month for average temperatures on record across the contiguous U.S., even surpassing the Dust Bowl. This was especially due to an increase in those dangerously high overnight temperatures. 📣 REGISTER for our next briefing to learn more: https://climatecentral-org.zoom.us/webinar/register/5817787808929/WN_bWZWT_KzSzOa7QaKahBg1A

  Evolution of July #Arctic sea ice and sea surface temperature (SST) anomalies during the satellite-era... A summary of last month can be found from @CopernicusECMWF@masto.ai at https://climate.copernicus.eu/sea-ice-cover-july-2026 *SST data set (OISSTv2.1) is only available since about 1982

  July 2026 set a new record for the month for near-surface air temperatures across the Tropics. Note the long-term warming trend as well (in all months), as indicated by the shading of the older (blue) to more recent years (red). Data from https://doi.org/10.24381/cds.f17050d7

  Sea surface temperatures are way above average in parts of the #Arctic as of last month, particularly in the Kara Sea Basin extending to around Svalbard and the Greenland Sea. This is also found in the Hudson Bay due to their very early sea ice melt-out. Data from NOAA OISSTv2.1.

  Wednesday El Niño update - Record warmth continues in the key monitoring region called Niño 3.4, which is due to both the long-term warming of the tropics (climate change) and the developing El Niño. Over the last 7 days, there has been a steady warming across the central Pacific. Data: NOAA OISSTv2.1.

  ICYMI - The newest data showing the number of billion-dollar disasters in the U.S. for the first half of 2026 was released last week. This includes 12 events costing nearly $32 billion in damages (5th highest for Jan-Jun event count). ➡️ Explore the data at https://www.climatecentral.org/climate-services/billion-dollar-disasters

  100 years of July sea surface temperature anomalies... you'll see important patterns of regional climate variability as the animation evolves, but ultimately, the story behind the long-term trend toward record warmth is driven by human-caused climate change. Data from NOAA ERSSTv6.

  Last month was the 5th lowest #Antarctic sea ice extent on record for the month of July. This was 950,000 km² below the 1981-2010 July average. Data from https://nsidc.org/data/seaice_index.

  Have a good week! Here's your Monday ice update - #Arctic sea ice extent is currently the 12th lowest on record (JAXA data)... • about 10,000 km² below the 2010s mean • about 840,000 km² below the 2000s mean • about 1,680,000 km² below the 1990s mean • about 2,440,000 km² below the 1980s mean Find more visuals: https://zacklabe.com/arctic-sea-ice-extentconcentration/

  Overnight temperatures are warming up across much of the contiguous United States during the month of August. Some of the largest trends are across the West, especially for daytime maximum temperatures (which I will post later).

  July 2026 #Arctic sea ice extent was the 6th lowest on record for the month... This was 1,760,000 km² below the 1981-2010 average. July ice extent is decreasing at about 6.80% per decade. Data: https://nsidc.org/data/seaice_index

  June saw a sharp gradient in temperature anomalies across the Canadian Arctic, with much warmer than average temperatures north of Hudson Bay (>5°C above the 1981-2010 mean) but relative cooler conditions toward the Beaufort Sea. Data from https://doi.org/10.24381/cds.f17050d7

  A quick look at a cross-section of temperature trends in the lower atmosphere during the month of July. The bottom of the y-axis is the lower troposphere, and the upper portion is reaching into the stratosphere. The x-axis is latitude. Data is provided by ERA5.

  Wednesday El Niño update - Some notable warming across a large part of the eastern half of the tropical Pacific Ocean during the last 7 days. And an ongoing strong westerly wind burst will continue to strengthen El Niño even further toward record territory. Data from NOAA OISSTv2.1. 🌊

  Sea surface temperatures are substantially warming around the entire #Arctic Ocean in July during the satellite-era. This is especially large in the Kara Sea. Note the blue shading mostly corresponds to areas of sea ice. Data by OISSTv2.1. For more info: https://doi.org/10.25923/pz7y-3b10

• Post #4196890

  There is little to no temperature trend over the Central #Arctic in summer due to basic heat flux exchanges from melting ice. However, adjacent areas show long-term warming in July. Data from ERA5 reanalysis. More info: https://doi.org/10.1175/BAMS-D-25-0104.1
