Analysis - Sea Ice Today
Antarctic sea ice extent appears to have broken the record low set last year. With a couple more weeks likely left in the melt season, the extent is expected to drop further before reaching its annual minimum.
Analysis - Snow Today
A series of atmospheric rivers significantly increased snow-covered area and snow water equivalent in the California Sierra Nevada, and to a lesser extent the delivery of snow inland to Nevada, Utah, and Colorado. Snow-covered area for the western United States was 125 percent of average for January with above average snow cover in most regions.
Analysis - Ice Sheets Today
Surface melting over Antarctica was near-average through January, but above average surface melting occurred on both the northeastern and southwestern areas of the Antarctic Peninsula.
Analysis - Sea Ice Today
Arctic sea ice extent rose at a slower than average rate through January, and continued to be below the lower interdecile range. By the end of the month, sea ice reached the second lowest extent in the satellite record.
