    California is facing monstrous wildfires, again. #CampFire #WoolseyFire The last 6 months have been among the hottest and driest May to Oct in California history, which increases the risk of explosive fires. A changing climate is increasing the wildfire risk in California.pic.twitter.com/ILnAmA8AXY

        PS. The data for this figure comes from @NOAA's Climate at a Glance data explorer, e.g. https://www.ncdc.noaa.gov/cag/statewide/time-series/4/tavg/6/10/1895-2018?base_prd=true&firstbaseyear=1950&lastbaseyear=1980 …

        I've created an updated version of this figure to better show the relationship between hot & dry weather in California and the largest and most destructive wildfires.https://twitter.com/RARohde/status/1061932205327429632 …

        This year, like 2017, California has had an unusually hot & dry fire season. Most of the largest and most destructive wildfires in CA history have happened under such conditions. Climate change is making this situation worse. #CaliforniaFires #ClimateChange pic.twitter.com/88bYtrigIL

        Can't imagine anyone denies California is currently at risk for wildfire; the issue is whether people have an incorrect view of what constitutes "normal" conditions. Despite the tragedy of human losses, California's recent fires were small compared to those I've experienced.pic.twitter.com/0E8MzIk7cM

        Prior to human efforts at fire suppression and aggressive land use management policies, natural burns likely were larger in many places. Though with or without fire management policies, if the climate gets hotter and drier, then the fires that do occur will become more extreme.

        That's undoubtedly true, but climate has likely been hotter & drier in the past, too. Don't know if current fires are natural or anthrpopogenic, but building in fire prone ecosystems is as risky as building on floodplains. Fire prevention and effective suppression are crucial.

        California's normal ecology requires wildfires in tthe presence and absence of Humans. The weather this year is not the hottest or driest experienced by California.

        Apparently you’re not reading the chart. This year IS one of the warmest and IS one of the driest.. not certain of your point other than denial of the fact our weather IS changing as HUMANS put more CO2 into the atmosphere.

        1. the chart is using falsified air temperatures systematically adjusted upwards & automated weather stations with erroneously high readings. 2. CA just experienced one of the wettest years on record. 3. Records too short to reflect worse conditions before recordkeeping began.

        Your source is NASA GISS, which is a group of political activists posing as climate scientists in an office located over a delicatessen in New York City. Their departure from norms of science was subject of written protests by the rest of NASA, including directors & astronauts.

        The work cited above is from scientists at the NASA's Jet Propulsion Laboratory, which is not related to NASA GISS. Not that there is anything wrong with NASA GISS, either.

        Let me tell you about JPL. Had a JPL PhD complain to us the PC sold to him was faulty, because 5.25 floppy disk didn't work in the drive. Said he removed the floppy disk from the envelope as instructed, & it was too floppy to work in the disk drive....

        A lot of us scientists wonder that too. More damage needs to happen, apparently, before voters are convinced, and political forces in denial start conceding policy space. It's like gun control. What's it going to take? Private sector insurance policy changes?
