Current climate alarmist fervor can be wholly undermined by the magnitude of change for the Antarctic ice sheet in recent decades. It’s IPCC AR6 Day (10 August, 2021) – a day devoted to celebratory alarmism. Here’s the larger perspective. The most concerning aspect of global warming is often identified as the threat of rising sea […]

From 1979-2018 East Antarctica cooled -0.70°C/decade (-2.8°C), West Antarctica cooled -0.42°C/decade (-1.68°C), but the Antarctic Peninsula warmed 0.18°C/decade (0.72°C). Thus, as a whole, the Antarctic continent has cooled by about -1.5°C to -2°C during the same period CO2 rose from 337 to 410 ppm. Zhu et al., 2021 “The temperature trend from ERA5 is consistent […]

Except for a few pockets of warming along the West Antarctic coast, surface air temperatures have cooled profoundly across East Antarctica – most of the continent, as well as the surrounding Southern Ocean – in the last 40 years (1979-2018). About 30% of the cooling can be explained by Madden-Julian Oscillation forcing. Atmospheric CO2 concentrations […]

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 […]

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 […]

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. AMO behind sea surface temperatures First we look at a paper authored by a team of German scientists: “Great Blue Hole (Lighthouse Reef, Belize): A continuous, annually-resolved record of Common Era […]

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 […]

In recent decades there have been “notable cooling trends” throughout many regions of the globe according to several new studies. A year ago NoTricksZone (NTZ) announced Greenland Has Been Cooling In Recent Years – 26 Of Its 47 Largest Glaciers Now Stable Or Gaining Ice. Six months ago NTZ cited several scientific papers indicating The […]

In her latest panic attack, teenage Swedish climate activist Greta Thunberg – citing the Guardian – once again appeared to be proclaiming the end of the world was a step closer when she tweeted Antarctica has set a new record high temperature: 20,7°C on Seymour Island off Antarctica… https://t.co/OiIdlQIl6A — Greta Thunberg (@GretaThunberg) February 13, […]

By Kirye and Pierre Gosselin Today we plot NASA Version 4 data for 19 Antarctic stations going back to 1988 (including volcanoes areas of West Antarctica and Peninsula), see map below. The 19 stations were chosen because they have both Version 3 and Version 4 data available. We plot the data on 4 different charts […]
