From NoTrickZone<\/a><\/p>\n\n\n\n

By\u00a0Kenneth Richard<\/a>\u00a0<\/em><\/p>\n\n\n\n

Scientists have counter-intuitively determined that a melting Antarctic ice sheet serves to mitigate global warming.<\/strong><\/h4>\n\n\n\n

The anticipated accelerated melting of the Antarctic ice sheet (AIS) will mean massive amounts of freshwater will enter the Southern Ocean (SO) over the next one hundred years.<\/p>\n\n\n\n

According to a new study<\/a><\/strong>\u2018s panoply of SOFIA (Southern Ocean Freshwater Input from Antarctica) models, a melting AIS will, in turn, cool the SO and Antarctica (the latter by 1\u00b0C or more) as well as lead to further expansion of the Southern Hemisphere\u2019s sea ice.<\/p>\n\n\n\n

More specifically, as a consequence of future Antarctic ice sheet melt, over the next century the entire 40-70\u00b0S region will cool ~0.7\u00b0C and sea ice will expand by approximately 2 million km\u00b2 (per Figure S1 from the study). The lead author already published a 2022 paper<\/a><\/strong> documenting \u201cthe Southern Ocean (50\u00b0S\u201370\u00b0S) sea surface temperature has a significant and robust cooling trend during 1982\u20132020,\u201d so the cooling trend has been ongoing for over 40 years already.<\/p>\n\n\n\n

The authors of the present study maintain the \u201cresponse to an increased Antarctic sea ice extent and ocean surface cooling results in global atmospheric impacts,\u201d not just local or regional ones. Specifically, the effect of SO cooling includes a (a) reduction in the global warming rate, (b) troposphere-wide cooling, (c) Eastern tropical Pacific cooling, (d) a delay in the anticipated weakening of the AMOC, (e) a northward shift of the ICTZ (Inner-Tropical Convergence Zone), and (f) a \u201cweakening of the jet stream on its equatorward flank in both hemispheres.\u201d<\/p>\n\n\n\n

In other words, the key to reducing the global warming \u201cproblem\u201d and its presumed side effects may be to cheer on (or hope for) an accelerated AIS melting over the next century.<\/p>\n\n\n\n

\u201cSince most of these responses act opposingly to global warming mechanisms diagnosed from model experiments lacking Antarctic freshwater, our results support the notion of a potential delay of anthropogenic climate change through SO [Southern Ocean] processes.\u201d<\/em><\/p>\n\n\n\n

For those who say a future accelerated Antarctic ice sheet melt will lead to concerning sea level rise, scientists contend this \u201cproblem\u201d may be self-correcting as well.<\/p>\n\n\n\n

According to the IPCC and climate models, if Antarctica were to ever warm (and it has not warmed in the last 70 years<\/a><\/strong>), this warmth would add more precipitation and thus ice mass to the Antarctic ice sheet (IPCC AR4<\/a><\/strong>, Krinner et al., 2007<\/a><\/strong>, Palerme et al., 2017<\/a><\/strong>). The warming-induced ice mass expansion contributes to a reduction in Antarctica\u2019s contribution to sea level rise by 2100. Specifically, a warming Antarctica reduces sea level rise by -1.2 mm\/yr.<\/p>\n\n\n\n

So a warming Antarctica leads to ice mass gains and a reduction in sea level rise, and a melting ice sheet leads to widespread cooling and sea ice expansion. Either way, the alarmist narrative loses.<\/p>\n\n\n\n
