Share this…FacebookTwitterThe northern North Atlantic’s sea ice records derived from ice cores and marine sediments consistently affirm there was far less sea ice during the Early/Mid Holocene than in 2000 CE. Even 17th to 19th century sea ice coverage was similar to (or less than) today’s. A 2020 study (Geirsdóttir et al.) indicated peak Holocene […]

Share this…FacebookTwitterPaleoclimate data indicate there was less Arctic sea ice during the pre-industrial period than in modern times, or when CO2 concentrations were 100 ppm lower than today (280 vs. 380 ppm). Scientists (Diamond et al., 2021) assert that during the 18th and 19th centuries Arctic sea ice extent minimum (September) values averaged 5.54 million […]

Share this…FacebookTwitterA new study (Kumar et al., 2021) reports the “overall SST trend in the Weddell Sea is negative” since 1979 and this has occurred in tandem with “the expansion of SIE [sea ice extent].” Another new study (King et al., 2021) reports the oldest temperature stations in Antarctica show a cooling/non-warming trend since 1956.

Share this…FacebookTwitterIn his 1975 book The Genesis Strategy, the late climate scientist Dr. Stephen Schneider reviewed contemporary climate modification proposals to reduce the severe 1960s and 1970s droughts, floods, and extreme weather…which were at that time associated with the ongoing global cooling. One proposal was to eliminate the Arctic’s sea ice by having aircraft dump […]

Share this…FacebookTwitterSea ice has been declining in the Canadian North Atlantic since the 1970s, and yet the harp seal population has been estimated to have risen from a little over 1 million in 1971 to about 7.5 million in 2012 to 2019. But model projections suggest the seal populations will decrease in the future due […]

Share this…FacebookTwitterIt was previously thought the northern limit for Southern Hemisphere sea ice was 55°S. But recent declines in surface air temperatures in southernmost South America have led to sea ice formation creeping 80 to 100 kilometers further north than previous estimates. Since 2000, sea ice has been extending well into 54°S. The southernmost tip […]

Share this…FacebookTwitterThough it has dropped since its peak in 1979, Arctic sea ice extent in March has remained stable since 2005. There are two months that are of particular interest in the Arctic: September, when sea ice reaches its minimum, and March, when it reaches its maximum. Gains 504,000 sq km. Today we look at […]

Share this…FacebookTwitterScientists (Liu et al., 2021) have assessed the Pacific North American (PNA) pattern, “largely a mode of internal variability,” is “an important driver of western Arctic sea variability and trends”. The heat-redistributing PNA pattern recently shifted from a negative (1980s) to positive (1995-) phase. This internal shift “induced significant increases in poleward heat” transport, […]

Share this…FacebookTwitterResearch on polar bear sightings using a systematic “regional marine mammal sightings programme” during 2005-2018 reveals there were 1,433 polar bears sightings from 2005-2011 compared to 2,569 during 2012-2018 around Svalbard. The perspective that polar bears are endangered by global warming because reduced sea ice limits their seal-hunting opportunities is again contradicted by real-world […]

Share this…FacebookTwitterThe 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; […]

Share this…FacebookTwitter 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 […]

Share this…FacebookTwitterA wealth of new research in glacier and sea ice extent show modern Iceland is 2-4°C colder than all of the last 8000 years except for a slightly colder late 19th century. Even the 1700s were warmer with less ice than today in and around Iceland. A new study (Geirsdóttir et al., 2020) now […]
