U zapanjujućem implicitnom priznanju, Međudržavni panel o klimatskim promjenama (Intergovernmental Panel on Climate Change – IPCC), znanstveno i međuvladino tijelo pod pokroviteljstvo Ujedinjenih naroda koje uživa u trubljenju o opasnostima klimatskih promjena, otkrilo je u novom izvješću da ne samo da postoji malo dokaza da je učestalost ekstremnih događaja poput suša, poplava, uragana i tornada porasla na globalnoj razini, već i da na te ekstremne događaje staklenički plinovi imaju malo utjecaja.
Unatoč zastrašujućim proklamacijama ekologa da je “potrebna akcija bez presedana” i IPCC-ovog vlastitog histeričnog upozorenja da vlada treba implementirati “brze, dalekosežne i bezprimjerne promjene u svim aspektima društva”, postoje neki ljudi bistrih glava koji su prozreli ovo napuhavanje, pogledali podatke i došli do nekih prilično drugačijih zaključaka.
Jedan od tih realista je Roger Pielke Jr., koji se nagrađen počasnim doktoratom Sveučilišta Linköping u Švedskoj, Nagradom za javnu službu Geološkog društva Amerike i nagradom Eduard Brückner u njemačkom gradu Münchenu 2006. godine za izvanredne uspjehe u interdisciplinarnom istraživanju klime.
Pielke je objavio temu na Twitteru koja dokumentira činjenice iz IPCC izvješća ignoriranog od mainstream medija:
1⃣A short thread on what the new @IPCC_CH report says about trends in extreme events, specifically: heat waves, drought, floods, tropical cyclones, tornadoes. Let's go . . .
— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
2⃣Temperature extremes: Nor change from AR5 or SREX
Very likely= ⬇️cold days and nights
Very likely= ⬆️warm days and nights
Likely= "consistent changes are detectable on continental scale in North America, Europe and Australia"— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
3⃣Drought. No change vs AR5
"low confidence in the sign of drought trends since 1950 at global scale… likely to be trends in some regions of the world, including increases in drought in the Mediterranean and W Africa & decreases in droughts in central N America & NW Australia"— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
4⃣Floods:
"There is low confidence due to limited evidence, however, that anthropogenic climate change has affected the frequency and the magnitude of floods. "— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
5⃣Floods:
"In summary, streamflow trends since 1950 are non-statistically significant in most of the world’s largest rivers (high confidence)"
Though some basins see up trends, some down.— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
6⃣Tropical cyclones:
"Numerous studies towards and beyond AR5 have reported a decreasing trend
in the global number of tropical cyclones and/or the globally accumulated cyclonic energy"— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
7⃣Tropical cyclones:
"there is only low confidence regarding changes in global tropical cyclone numbers under global warming over the last four decades."— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
8⃣Tropical cyclones:
" There is consequently low confidence in the larger number of studies reporting increasing trends in the global number of very intense cyclones."— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
9⃣Tornadoes. Not mentioned.
— Roger Pielke Jr. (@RogerPielkeJr) October 8, 2018
1⃣0⃣Bottom line.
The IPCC once again reports that there is little basis for claiming that drought, floods, hurricanes, tornadoes have increased, much less increased due to GHGs.
In short, this is still right: https://t.co/rbbWuwIw8S
