Global Warming Science -


Fire !


[last update: 2018/08/13]




climate change doubled the expansion of forest fires in the western United States over the last 31 years. The hardest-hit locations include places in the Pacific Northwest, such as the Cascade Mountains in eastern Oregon and eastern Washington, and the northern Rocky Mountain territories that cross Idaho, Montana and Wyoming. … These are all areas where fires were especially influenced by climate change

Since 1975 annual wildfire acreage burned has increased more than 100%


The above graph confirms the PBS story!




Here is the entire graph:


As usual, the mainstream media cherry-pick the start year so that the long-term picture, which actually shows a very different story, is obfuscated.












Oh you mainstream media! Ignore what scientists say – it’s all climate change… and that damn Trump’s fault!

With major fires burning in California, the media is abuzz with stories suggesting or stating that global warming is the key driver of these big burns.  Some media reports state that the number of California fires and the annual burn area are increasing and that global warming is the cause.    California's Governor Jerry Brown is absolutely explicit about the climate-wildfire connection, claiming that global warming is creating a "new normal" of increased wildfires and that the population will have to get used to it.

The bottom line of the real fire data produced by the State of California and in the peer-reviewed literature is clear:  there has been no upward trend in the number of wildfires in California during the past decades.   In fact, the frequency of fires has declined.


He also provides the following from CalFire and states: “the Cal Fire areas, which encompasses lower elevations with greater overlap with human populations, the largest areas burned occurred in the early part of the 20th century.  The only exception to this pattern is the south coast, where there is little trend.

From a 2018 paper “Spatial and Temporal Variability and Trends in 2001 – 2016 Global Fire Activity”, Earl & Simmonds: Journal of Geophysical Research: Atmospheres, 123(5), 218:



The mainland United States …displays no 2001–2016 trend in [active fires] … This is also the case for the satellitebased [burned area] studies (Andela et al., 2017; Giglio et al, 2013), though BA has been found to be increasing in some surfacebased U.S. studies (see Doerr & Santín, 2016). This is surprising, as the economic costs of wildfire in the United States have risen substantially in recent decades and from 1992 to 2012, with anthropogenically ignited wildfires accounting for 84% of all wildfires.” The largest 2018 California fires were also started by human ignition – Smokey Bear still needs our help!

Smokey says: “people have helped me reduce the number of acres burned from about 22 million in 1944 to an average 6.5 million today
