The IPCC-endorsed anthropogenic global warming (AGW) paradigm finds a warming Antarctica results in more precipitation locked up as ice on the continent. This contributes to reducing sea levels: a -1.2 mm/year−1 mitigation of sea level rise over the next 80 years. In the 4th IPCC report, Working Group 1 (the physical science) reported that as […]

Alfred Wegener Institute: Sea ice development in both polar regions at normal level Arctic On 31 January, 2021, the sea-ice extent in the Arctic was 14.29 million km², roughly the same level as in the previous two years. In terms of the long-term trend for the month, January 2021 comes in at 7th place with […]

By Kirye and Pierre Today we update 12 stations located at the eastern side of Antarctica, where surface temperatures are colder than those located near the peninsula: Chart: NASA-GISS. Below the NASA data from the 12 stations are plotted going back almost 4 decades, to 1983. The first chart has 4 of the stations, and […]

NASA mean annual temperature data going back a quarter century show no warming over Antarctica By Kirye and Pierre Gosselin Where’s the warming and ice melt? Today we revisit 13 critical stations located on and around the Antarctic Peninsula. They are important because alarmists like to tell and scare us that the ice mass on […]

The survivable temperature thresholds for terrestrial animals in both hemispheres affirm recent millennia were much warmer with less sea ice than today. Antarctica hasn’t warmed in the last 70 years (Singh et al., 2020). The Southern Ocean surrounding Antarctica has been cooling and sea ice has been expanding since 1979 (Fan et al., 2014; Qian […]

In 2020, more than 400 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Over 400 scientific papers published in […]

By Kirye and Pierre Gosselin Before looking at Antarctica Peninsula, we first take a look at Greenland, which also is considered by the global warming alarmists to be part of the most threatening tipping points. If the ice on Greenland ever melted, like they warn it will, sea levels globally would rise some 6 meters. […]

Only a few thousand years ago, when CO2 levels were both stable and low (~265 ppm), the (1) Arctic had far less ice and more vegetation than it does now and (2) the massive rate of ice melt in Antarctica rendered modern melt rates negligible by comparison. A new study (Cherezova et al., 2020) reveals […]

As recently as 2000 to 1000 years ago, spanning the Roman to Medieval Warm Periods, East Antarctica was 5-6°C warmer than it is today. The consequent ice melt resulted in >60 meters higher water levels in East Antarctica’s lakes. East Antarctica has been rapidly cooling in recent decades, with magnitudes reaching -0.7°C to -2.0°C per […]

Today we present two papers on climate reconstruction using proxy data. One about East Antarctica and the other about belize. Hat-tip reader Mary Brown.

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”. Image Source: Doran et al., 2020 Obryk et al. (2020) – with […]

A new temperature reconstruction indicates today’s sea surface temperatures are colder than all but a few millennia out of the last 156,000 years. A Southern Ocean site analyzed in a new study (Ghadi et al., 2020) has averaged 1-2°C during glacials and 4°C during interglacials. Today, with a 410 ppm CO2 concentration, this location has […]
