Winds keep changing as warming continues

November 2017 was 0.87 degrees Celsius warmer than the mean 1951-1980 November temperature, as above image shows. The last three Novembers — 2015, 2016, and 2017 — are the three warmest in the entire modern record. The warmest month of November happened in 2015 (+1.03°C) when there was a strong El Niño , while we're currently in a La Niña period. On the image below, cyclonic winds on December 21, 2017, are visible near the Philippines and Vietnam. Near the Philippines, 3-hour precipitation accumulation was as high as 121.6 mm or 4.79 in (at green circle). As a BBC report describes, Tropical Storm Tembin made landfall in the southern Philippines on December 22, 2017, causing flash flooding and mudslides. More than 180 people are reported to have been killed, as the tropical storm swept through Mindanao island, with dozens more missing. A week earlier, Tropical Storm Kai-Tak hit the central Philippines, killing dozens. The region is still recovering from Typhoon Haiyan, which kill

Fires threaten Santa Barbara

New mandatory evacuation orders have been issued for the areas of Montecito, Summerland and some parts of Santa Barbara city, emergency officials said. Above graph shows carbon monoxide (CO) and carbon dioxide (CO₂) levels from December 5 - 20, 2017, while the map below shows the location of the measurements (and forecasts). The graph shows levels at one location and for one time of day (00:00 UTC for CO, respectively 01:30 UTC for CO₂). On December 11, 2017, at this location, but at 22:30 UTC, CO levels were 55639 ppb and CO₂ levels were 898 ppm, as illustrated the combination image below (left panel). The right panel of the image below shows that CO₂ levels were as high as 922 ppm on December 7, 2017, at 01:30 UTC at a slightly different location. No CO₂ measurements were available for December 9 and 10, 2017, but given that levels of CO₂ and CO typically go up and down hand in hand, CO₂ may have peaked at well over 1000 ppm on December 9, 2017, possibly exceeding the 1229 ppm CO₂ me
