Dare you to post it on Facebook

05 May 2021 | Science Notes

In this feature we offer you some outrageous denier propaganda that you can post on your Facebook page in the hopes of attracting the ire of the army of Facebook fact-checkers. Then, after they’ve canceled your account and got you fired from your job, you can show them the source, which we reveal below the fold comes from official sources like the IPCC. Which should at least get your Facebook page back up, but no guarantees about your job. This week’s dare: “Anyone who says global warming means more droughts is just making it up to scare you. Scientists don’t know. The IPCC once said droughts have been getting more frequent globally but that’s wrong. They’ve gone up some places and down others. Big deal. That’s how it goes.”

This one comes from the IPCC Fifth Assessment Report Working Group I, Chapter 2, page 215 (with the “AR4” reference to the previous IPCC Report in 2007) where they politely toss their earlier comments on droughts in the dumpster:

In summary, the current assessment concludes that there is not enough evidence at present to suggest more than low confidence in a global-scale observed trend in drought or dryness (lack of rainfall) since the middle of the 20th century, owing to lack of direct observations, geographical inconsistencies in the trends, and dependencies of inferred trends on the index choice. Based on updated studies, AR4 conclusions regarding global increasing trends in drought since the 1970s were probably overstated. However, it is likely that the frequency and intensity of drought has increased in the Mediterranean and West Africa and decreased in central North America and north-west Australia since 1950.

So go ahead. Post it on Facebook and see what they say.
