Nya oroande upptäckter om Thwaites-glaciären på Antarktis

Orsaken till det stora spannet finns främst i osäkerheter kring hur snabbt isen på Grönland och främst Antarktis smälter.


Den största orosfaktorn är Thwaites-glaciären på Antarktis, även kallad ”domedagsglaciären”, som är större än hela Götaland och hela Svealand tillsammans och innehåller tillräckligt mycket vatten för att kunna få världshaven att stiga med runt 65 centimeter, vilket skulle ta flera århundraden. 


Nu kommer nya oroande upptäckter på området. I maj konstaterade forskare att en stor del av Thwaitesglaciären, en 300 meter tjock flytande ismassa – så kallad isshelf – lika stor som London på dess östra sida, är på väg att brytas loss.

Förmodligen sker det redan i år. Det väntas få resten av glaciären att snabbare glida ut i havet.

– Södra Skåne är absolut värst utsatt.

Längst ner i söder, där landhöjningen efter istiden är näst intill obefintlig.

The reduction in ice and snow will not only change how the Himalayas look, it will also impact the lives of hundreds of millions of people and many ecosystems in the region.

China possesses 20% of the world’s population but only 7% of its fresh water.

Pfizer in 2019 sold $20 billion of drugs in the U.S. Its federal tax bill? Zero; Ireland

Trump has already singled out pharma companies and countries like Ireland that reap the benefits of tax-avoidance moves.  Despite its small size, Ireland ran an $87 billion trade surplus with the U.S. last year—larger than any country except China, Mexico and Vietnam. https://www.wsj.com/health/pharma/how-trumps-tariffs-could-upend-pharmas-overseas-tax-strategy-5b8ca758 Is Ireland vulnerable again as the world’s vast shadow banking system starts to crack? Shadow banking is the dog that has not barked during the latest global spasm of financial stress. This is very fortunate, especially for small countries such as Ireland that have bet the farm on this industry. https://englundmacro.blogspot.com/2023/04/is-ireland-vulnerable-again-as-worlds.html Cayman Islands https://en.wikipedia.org/wiki/Cayman_Islands What the heck is happening in the Cayman Islands?

Cognitive blind spots

Bild
Cognitive blind spots are undermining our ability to see the world as it is, rather than as we would like it to be. At the start of the 21st century, western elites generally assumed that globalisation, democracy and the free market were self-evidently good, and would keep spreading, creating peace. N o longer.  FIS, Swiss Federal Intelligence Service, has published a manual about cognitive blind spots. 18 different cognitive biases that hamper our thinking, such as “group think” (adhering to the cosy assumptions of our tribe), “anchoring” (relying exclusively on whatever information we see first, say on social media),  “confirmation bias” (only seeing data that reinforces pre-existing views),  “mirror imaging” (assuming others think like us),  “absence of evidence” bias (failing to think about the data we lack)  and “survivorship bias” (judging data only with success stories, not failures).
