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 measured in Montana on July 22, 2017.

Such fires look set to cause increasing amounts of emissions, speeding up warming of the atmosphere. These fires were fueled by extremely dry, hot and strong winds lasting for many days. Global warming is behind all these conditions. Not only does more heat translate into higher temperatures and stronger winds, the decreasing temperature difference between the Arctic and the Equator is also increasing the intensity and duration of more extreme weather events such as storms and droughts. A record 129 million trees on 8.9 million acres have died in California due to drought and bark beetles infestation.

“For the first time in history, on December 7th, the Cal Fire elevated the fire threat to purple for San Diego County, warning that the weather conditions presented an extreme risk of fire for San Diego,” California Governor Jerry Brown wrote in a request for federal emergency assistance. “Fire officials predict extreme winds of up to 80 miles per hour, equal to the wind speed of a category one hurricane.”

The following is an extract from the California Scoping Plan 2017:
In California, as in the rest of the world, climate change is contributing to an escalation of serious problems, including raging wildfires, coastal erosion, disruption of water supply, threats to agriculture, spread of insect-borne diseases, and continuing health threats from air pollution. The drought that plagued California for years devastated the state’s agricultural and rural communities, leaving some of them with no drinking water at all. In 2015 alone, the drought cost agriculture in the Central Valley an estimated $2.7 billion, and more than 20,000 jobs. Last winter, the drought was broken by record-breaking rains, which led to flooding that tore through freeways, threatened rural communities, and isolated coastal areas. This year, California experienced the deadliest wildfires in its history. Climate change is making events like these more frequent, more catastrophic and more costly.

The situation is dire and calls for comprehensive and effective action as described at the Climate Plan.
