Share this…FacebookTwitterBy 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 […]

Share this…FacebookTwitterOnly 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) […]

Share this…FacebookTwitterAs 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 […]

Share this…FacebookTwitterScientists 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) – […]

Share this…FacebookTwitterA 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 […]

Share this…FacebookTwitterIn 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 […]

Share this…FacebookTwitterOver the past 40 years of satellite observation, Antarctic sea ice defied global warming predictions and gained impressively. The mean temperature of the southern ice cap also shows no warming. In 2017, after decades of inconvenient rise, sea ice extent suddenly fell to record low level and panic activity among global warming alarmists began […]

The scientists found that the ice shelf is prograding (expanding), and not breaking apart like some alarmist scientists feared earlier. Image: cropped from Wikipedia. Hat-tip: Mary Brown […]

By Kirye and Pierre Gosselin We keep hearing how the ice at the poles is supposedly disappearing rapidly, yet a look at the latest data show this is not the case. Polar ice has remained steady for the last […]

Share this…FacebookTwitterGreenland’s largest glacier (Jakobshavn) has quite abruptly thickened since 2016. The thickening has been so profound the ice elevations are nearly back to 2010-2011 levels. The nearby ocean has cooled ~1.5°C – a return to 1980s-era temperatures. The world’s glaciers have not been following along with the CO2-driven catastrophic melting narrative. Alaska For example, […]
