New Study: Antarctic Ice Sheet Melt Will Lead To Widespread Cooling, Sea Ice Expansion

New Study: Antarctic Ice Sheet Melt Will Lead To Widespread Cooling, Sea Ice Expansion

Scientists have counter-intuitively determined that a melting Antarctic ice sheet serves to mitigate global warming. The anticipated accelerated melting of the Antarctic ice sheet (AIS) will mean massive amounts of freshwater will enter the Southern Ocean (SO) over the next one hundred years. According to a new study‘s panoply of SOFIA (Southern Ocean Freshwater Input […]

Antarctic Elephant Seal Breeding Site Affirms There Was Far Less Sea Ice During Medieval, Roman Periods

Antarctic Elephant Seal Breeding Site Affirms There Was Far Less Sea Ice During Medieval, Roman Periods

DNA evidence suggests the limit of Antarctic sea ice was ~2000 kilometers farther south than it is today 2500 to 1000 years ago. Elephant seals can only breed in the Southern Ocean’s subantarctic, sea ice free waters. For example, today’s largest colony breeds on Macquarie Island (54.5°S). Scientists (Wood et al., 2025) have now identified […]

New Study: 43 Years Of An Increasing Antarctic Sea Ice Trend

New Study: 43 Years Of An Increasing Antarctic Sea Ice Trend

According to a new study, the recent short-term (2011-2022) decreasing Antarctic sea ice concentration (SIC) trend has not offset the overall 43-year (1979-2022) trend of increasing Antarctic SIC. The strongly negative sea surface temperatures and SIC correlation coefficient (-0.73) indicates the waters around Antarctica have undergone a long-term cooling trend.

Scientists 'Unexpectedly' Find The Declining Sea Ice Trend Since 1980 Has Radiatively Cooled The Earth

Scientists ‘Unexpectedly’ Find The Declining Sea Ice Trend Since 1980 Has Radiatively Cooled The Earth

The alarmist narrative that says disappearing sea ice serves to enhance and worsen global warming may now be discarded. For decades it has been assumed the sea ice concentration (SIC) reduction trend in the the Arctic over the first 30 years of the satellite era (1979-2007, with a flat trend since then) would lead to […]

The Barents Sea Was Seasonally Ice Free For Much Of The Holocene...Today It's Ice-Covered Year-Round

The Barents Sea Was Seasonally Ice Free For Much Of The Holocene…Today It’s Ice-Covered Year-Round

More evidence has emerged suggesting there is more sea ice in the Arctic today than nearly any time in the last 8000 years. According to a new study, biomarker evidence suggests the Barents Sea (Arctic) was seasonally “ice free” from ~8000 to ~2100 years ago, or back when the CO2 concentration was said to be […]

'Global' Warming? Little Ice Age Cooling And Sea Ice Expansion Is Still Ongoing Across Antarctica Today

‘Global’ Warming? Little Ice Age Cooling And Sea Ice Expansion Is Still Ongoing Across Antarctica Today

New research indicates there has been no reduction in sea ice in Antarctica’s Robertson Bay (Ross Sea) during the last century. Instead, the frigid Little Ice Age and its expanded sea ice conditions continue unabated through the 20th and 21st centuries. Between ~8000 and 3500 years before present the Antarctic ice sheet experienced several millennia […]

New Study: Antarctic Sea Ice Has Been Increasing Since The 1970s...Due To Internal Decadal Variability

New Study: Antarctic Sea Ice Has Been Increasing Since The 1970s…Due To Internal Decadal Variability

“Since the late 1970s, Antarctic sea ice area (SIA) has slowly increased, despite significant global warming. The increase in Antarctic SIA occurred largely between 2000 and 2014.” – Bonan et al., 2024 Scientists attribute the long-term (1979-2022) expanding Antarctic sea ice trend, as well as the abrupt decline in sea ice extent from 2016 to […]

New Study Finds Arctic Warming, Declining Sea Ice May Be A 'Benefit' To Polar Bears And Ringed Seals

New Study Finds Arctic Warming, Declining Sea Ice May Be A ‘Benefit’ To Polar Bears And Ringed Seals

The polar bear plight has quietly disappeared from the catastrophic global warming narrative. According to new research, the body condition of polar bears and ringed seals (their prey) has been stable to improving from 2008-2022 despite Arctic warming and sea ice decline during this period. This is the opposite of what was predicted to happen, […]

Arctic Sea Ice 'Choke Points' Reducing NW Passage Shipping Season Length By 5-14 Weeks Since 2007

Arctic Sea Ice ‘Choke Points’ Reducing NW Passage Shipping Season Length By 5-14 Weeks Since 2007

Global warming was supposed to open up Arctic region shipping routes, making the Northwest Passage easier and less risky to traverse. Per a new study, the opposite has happened. As we reported earlier this year, while a declining trend in Arctic sea ice was observed from the 1990s to 2007, there has been no trend […]

The Embarrassing Pause In Arctic Sea Ice Loss Has Lasted 17 Years, Defying IPCC, NSIDC Predictions

The Embarrassing Pause In Arctic Sea Ice Loss Has Lasted 17 Years, Defying IPCC, NSIDC Predictions

“[S]ince the dramatical decline of the ice extent in 2007, the summer Arctic sea ice area has not declined further.” – Astrup Jensen, 2023 Scientists have been using the year 2007 as the starting point for assessing Arctic sea ice trends for nearly a decade. A 2015 study published in Nature Climate Change reported a “near-zero […]

The Narrative That Polar Bears Need Sea Ice To Catch Prey Has Collapsed As More Evidence Piles Up

The Narrative That Polar Bears Need Sea Ice To Catch Prey Has Collapsed As More Evidence Piles Up

Arctic regions with 6+ months of sea ice coverage today were ice-free nearly year-round 9,000 to 5,000 years ago (2°C warmer) and 130,000 to 115,000 years ago (7-8°C warmer). And yet polar bears survived these periods. Per a new study, today’s Scandinavian Arctic climate is so cold it is actually “comparable” to that of the […]

New Study: Modern Sea Ice Extent Is Nearly The Highest In 9000 Years Across the Arctic

New Study: Modern Sea Ice Extent Is Nearly The Highest In 9000 Years Across the Arctic

Millennial-scale Arctic sea ice reconstructions do not corroborate alarmist claims of unprecedented sea ice losses in modern times.  Using sea ice biomarker proxy (IP25), scientists (Kolling et al., 2023) have determined that the sea ice extent in the Labrador Sea was nearly absent throughout the year (close to 0.0 μg/gTOC) for much of the last […]
