Holocene (11,700 to 8,200 years ago) Arctic (Svalbard) temperatures “were up to 9°C higher than today” according to the authors of a new Nature journal study. At that time CO2 was thought to only hover around 260 ppm.
Svalbard then cooled as CO2 rose for the next 8,000 years – a negative correlation that wholly contradicts the rising-CO2-drives-Arctic-warmth narrative.
Nonetheless, climate models are predicated on the assumption rising human CO2 emissions (RCP 8.5) will lead to a warming of ~8°C by 2100.
