New Study: Southern Hemisphere Sea Ice Now Extends ~80 km Farther North Than Prior Estimates

It 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 of […]

March Sea Ice: Arctic Stable 16 Years, Gains 504,000 Sq Km Since 2017! Antarctic Above Mean!

Though 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 Arctic […]

New Study: 75% Of Recent Arctic Sea Ice Decline Is ‘Accounted For’ By An Internal Variability Pattern (PNA)

Scientists (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, explaining […]

New Study Finds A 79% Rise In Polar Bear Sightings Since 2005 As Their Arctic Habitat Dramatically Expands

Research 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 observations. […]

Seals, Mammoths, Horses, Waterfowl…All Tell Us Claims Of Exceptional Modern Warmth Are Bull Hockey

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 […]

Modern Iceland’s Climate Is Colder With More Ice Than Any Other Time In The Last 8000 Years Except The 1800s

A 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 affirms […]

Astrophysicist Asserts The Globe Will Cool ~1°C During 2020-2053 Due To An Oncoming Grand Solar Minimum

During the last Grand Solar Minimum (17th century), global surface temperatures dipped to the coldest of the last 10,000 years – about 1.4°C colder than today. Dr. Zharkova, an astrophysicist, has determined another imminent drop in solar activity will lead to a 1°C cooling in the coming decades. From 1645 to 1710, the Sun went […]

New Northern North Altantic Study Finds The Coldest Period With The Most Sea Ice Of The Last ~85 Years…Is Today

Ecological conditions for 3 temperature- and sea ice-sensitive species show the sub-Arctic North Atlantic has been cooling and gaining ice since 1940. In recent months, several scientific publications have documented a dramatic cooling trend in the subpolar North Atlantic, with temperatures plummeting 2°C since 2008 (Bryden et al., 2020) or -0.78°C per decade since 2004 […]

Climate Alarmist Claim Blown to Smithereens: Unlikely That Warm Arctic Leads To Cold Winters

Image: NASA (public domain) By Die kalte Sonne Do you remember the wild story that cold winters in Central Europe are supposedly a consequence of the Arctic turbo-heating? A great sideshow hypothesis in those years when winters were suddenly colder than expected. A study by Dai & Song 2020 has now brought the idea back to […]

New Study Indicates Iceland Must Have Been 3°C Warmer During The Early Holocene To Match The Glacier Record

During the Early Holocene, when CO2 levels lingered near 260 ppm, ice core records suggest surface temperatures in Iceland were about 3°C warmer than today. Iceland’s extensive lakes and glaciers topography provides a verifiable history of the region’s paleoclimates. For example, scientists can infer summer temperatures 3°C warmer than today in Iceland to account for […]
