Den stora tråden om global uppvärmning/växthuseffekten

I dagarna väntas omkring 24 miljoner amerikaner leva i 46 grader. Vilket sätter stor press på landets sjukhus och myndigheter.

I Arizona har myndigheter slagit upp mobila kliniker som behandlar hemlösa som lider av tredje gradens brännskador och svår uttorkning tillföljd av värmen.

I Las Vegas är akutmottagningarna överfulla efter att både lokalbefolkning och turister fallit ihop i värmen, rapporterar CNN.

Å Putin den jävla galningen ska till Sydafrika. Kommer han svettas ihjäl? Det lär ju va fett varmt där nere. https://www.aftonbladet.se/nyheter/a/P42okR/putin-vill-delta-pa-brics-toppmote-kan-gripas-av-icc

Sea surface temperature and marine air temperature averaged over all ice-free seas were the highest on record for May.

The month of June was exceptionally warm for the time of the year in the global surface ocean, with a large contribution of extremely high temperatures for June in the North Atlantic and the Southern Ocean . In terms of surface air temperature, June 2023 was also the warmest June globally by a large margin at 0.53°C above average, according to the latest monthly bulletin of the Copernicus Climate Change Service (C3S).

By the 1970s, scientists were becoming increasingly aware that estimates of global temperatures showed cooling since 1945, as well as the possibility of large scale warming due to emissions of greenhouse gases. In the scientific papers which considered climate trends of the 21st century, less than 10% were inclined towards future cooling, while most papers predicted future warming.[1] The general public had little awareness of carbon dioxide's effects on climate, but Science News in May 1959 forecast a 25% increase in atmospheric carbon dioxide in the 150 years from 1850 to 2000, with a consequent warming trend.[2] The actual increase in this period was 29%. Paul R. Ehrlich mentioned global warming from greenhouse gases as a counterforce to the cooling effect of aerosols in 1968.[3] By the time the idea of global cooling reached the public press in the mid-1970s temperatures had stopped falling, and there was concern in the climatological community about carbon dioxide's warming effects.[4] In response to such reports, the World Meteorological Organization issued a warning in June 1976 that "a very significant warming of global climate" was probable.[5]
