We apparently owe Al Gore an apology because more floods and more tornados Except fewer tornados and not linked to climate Except lower damage from flooding and not linked to climate The insidiousness of climate alarmism: always something to worry abouthttps://www.npr.org/2019/06/08/730456004/more-people-see-climate-change-in-record-floods-and-extreme-weather-will-that-me …

Increase in all tornados because increased measurement of weak tornados (bc doppler radar) "can create a misleading appearance of an increasing trend in tornado frequency" — as Al Gore did in his film https://web.archive.org/web/20120609061229/www.ncdc.noaa.gov/oa/climate/severeweather/tornadoes.html …pic.twitter.com/RG9drykQK0

UN Climate Panel's report on extreme weather found that there is low confidence projections of tornados because we can't model them https://www.ipcc.ch/report/managing-the-risks-of-extreme-events-and-disasters-to-advance-climate-change-adaptation/ …, p13pic.twitter.com/2X30psBNxf

The UN Climate Panel can't see a trend in flooding — it doesn't even now if global flooding is going up or down (sign) So, no, flooding is not showing global warming https://www.ipcc.ch/report/ar5/wg1/ , p112pic.twitter.com/s86wQlC4uy

The US Climate Assessment says that while there is both increases and decreases in flooding, it is not possible to attribute flooding to human-induced climate change https://science2017.globalchange.gov/chapter/8/ page 231pic.twitter.com/s5fq9iKRGh

(Yes, climate is real, mostly human-made and a problem But it is *not* a crisis/catastrophe It will cost perhaps 2-4% of GDP by end of century, when our average income will be 300-500% of today's Here from Nobel climate economist Nordhaus https://www.nber.org/reporter/2017number3/nordhaus.html …)pic.twitter.com/pGmTlUhoDr
