Scientists extend a 15-station East Antarctica record from 1986 to 2017 and find a -0.7°C per decade cooling (-1.4°C total) until 2006, but no trend from 2006-2017. 

Doran et al (2002) reported “a net cooling on the Antarctic continent between 1966 and 2000”.

Obryk et al. (2020) – with P.T. Doran a co-author – have extended the Doran et al. (2002) record to 2017 and found the -0.7°C cooling that lasted from 1986 to 2000 persisted until 2006. A recovery since 2006 has been observed, but not enough to be documented as statistically significant.

Turner et al. (2020) report cooling of the Antarctic Peninsula since about 2000 and no net warming in East Antarctica since the early 1980s.

Hrbáček and Uxa, 2020 report a “significant air temperature decrease started around 2000 along most of the Western AP [Antarctic Peninsula].” Specifically, “the north‐eastern AP region exhibited a MAAT more than 1°C lower in the period 2006–2015 compared to 1996–2005, and autumn (MAM) air temperature was even about 1.5°C lower.”

Fatras et al., 2020 find “a cooling of -0.60°C/decade of the air temperature for Greenwich Island” (Antarctica) from 1998 to 2015.

In summary, scientists have been consistently documenting significant cooling trends throughout the Antarctic continent in recent decades despite the common media portrayals of rapid Antarctic warming in response to human activities.

    My conclusion is then the climate in that area of the Antarctic is pretty stable over the measured time period. Well well what a surprise.

    One ‘official’ climate cycle (that is FAR too short) only shows the normal amount of weather variations and not much else.
    Still it does show that all the alarmists, Hansen, and the IPCC were wrong about imminent rapid warming happening very soon as they did from the late 1980s onward.
