A current paper saying Pine Island Glacier doom failed to think about different findings exhibiting the glacier is in truth extra steady than assumed.
A brand new paper by Rosier et al concludes – primarily based on mannequin simulations – that the Pine Island, West Antarctica, glacier could have already surpassed one of many three harmful tipping factors, prompting the media to subject warnings of doom, so studies Die kalte Sonne right here in its newest data video.
The scientists worry that ought to the Amundsen Sea water temperature rise 1.2°C, the Pine Island Glacier would retreat and set off the collapse of the whole West Antarctic Ice Shelf (WAIS, which in flip would imply a speedy international sea stage rise of over three meters.
Concerned within the the Rosier et al examine was Stefan Rahmstorf-mentored researcher Ricarda Winkelmann of the Potsdam Institute.
However different publications present no doomsday
Nevertheless, as Die kalte Sonne factors out, the crew of scientists ignored an enormous physique of science that contradicts their dire findings. For instance, a 2017 publication by Bingham et al explains how the researchers truly surveyed to mighty Pine Island glacier (PIG) and located that the terrain’s traits would in truth decelerate the retreat even beneath a warming local weather:
Additionally a 2014 publication by Beem et al discovered that one other glacier within the area had seen a deceleration in retreat over the earlier 50 years.
Volcanoes, pure cycles at play
In 2018, a paper by Free et al discovered that the Pine Island glacier was sitting over volcanic exercise, which was offering warmth for melting.
Additionally one other 2014 publication by Witus et al discovered that over the Holocene there have been repeated intervals of speedy ice soften at Pine Island:
And once more in 2018 a publication by Barletta et al discovered that “noticed bedrock uplift” in truth would possible stabilize the Pine Island Glacier, “and make a collapse inconceivable”.
Die kalte Sonne brings up the query: Why had been these earlier research – many primarily based on observations – ignored by Rosier et al? “Exhausting to imagine they had been,” says the Die kalte Sonne video report. Certainly they should have been conscious of those publications?
Amundsen Sea cooling!
Additionally very peculiar is the truth that Rosier et al additionally appear to disregard the information from the ARGO measurement buoys within the space. Recall that sea floor temperatures there (Amundsen Sea) rising 1.2°C would imply passing the third and last “harmful” tipping level and result in WAIS collapse.
So what’s the development there?
Supply: Local weather Explorer
The Amundsen Sea has been cooling over the previous 15 years!
Die kalte Sonne summarzes:
The [Rosier et al] tipping level paper with the PIK penmanship on it doesn’t look so convincing and ignores all the pieces that doesn’t match their very own thought.”
