Scientists Struggle to Understand Why Antarctica Hasn’t Warmed for Over 70 Years Despite Rise in CO2

Scientists are scrambling to explain why the continent of Antarctica has shown Net Zero warming for the last seven decades and almost certainly much longer. The lack of warming over a significant portion of the Earth undermines the unproven hypothesis that the carbon dioxide humans add to the atmosphere is the main determinant of global climate.
Under ‘settled’ science requirements, the significant debate over the inconvenient Antarctica data is of necessity being conducted well away from prying eyes in the mainstream media. Promoting the Net Zero political agenda, the Guardian recently topped up readers’ alarm levels with the notion that “unimaginable amounts of water will flow into oceans”, if temperatures in the region rise and ice buffers vanish. The BBCgreen activist-in-chief Justin Rowlatt flew over parts of the region and witnessed “an epic vision of shattered ice”. He described Antarctica as the “frontline of climate change”. In 2021, the South Pole had its coldest six-month winter since records began in 1957, a fact largely ignored in the mainstream. One-off bad weather promoter Reuters subsequently ‘fact checked’ commentary on the event in social media. It noted that a “six-month period is not long enough to validate a climate trend”.
A recent paper from two climate scientists (Singh and Polvani) accepts that Antarctica has not warmed in the last seven decades, despite an increase in the atmospheric greenhouse gases. It is noted that the two polar regions present a “conundrum” for understanding present day climate change, as recent warming differs markedly between the Arctic and Antarctic. The graph below shows average Antarctica surface temperatures from 1984-2014, compared to a base period 1950-1980.
