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

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

Share this...

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 […]

Share this…FacebookTwitterThe southwestern US was nearly a desert from about 9000 to 5000 years ago, when Holocene peaks in aridity, surface temperature, and wildfire rates occurred. Arctic sea ice was at its lowest extent of the Holocene during these years. Image Source: Lachniet et al., 2020 A new extensively-referenced study (Lachniet et al., 2020) reviewing […]

3 More New Studies Show Modern Arctic Sea Ice Extent Is Greater Than Nearly Any Time In The Last 10,000 Years

3 More New Studies Show Modern Arctic Sea Ice Extent Is Greater Than Nearly Any Time In The Last 10,000 Years

Share this…FacebookTwitterFor years scientists have been using biomarker evidence (IP25, PIP25) to reconstruct the Arctic’s sea ice history. The evidence shows modern (20th-21st century) Arctic sea ice is at its greatest extent since the Holocene began. Scientists (Wu et al., 2020) have determined that from about 14,000 to 8,000 years ago, when CO2 lingered near […]

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

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

Share this…FacebookTwitterDuring 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 […]

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

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

Share this…FacebookTwitterEcological 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 […]

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

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

Share this...

Share this…FacebookTwitter 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 […]

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

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

Share this...

Share this…FacebookTwitterDuring 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 […]

New Research: Polar Bears' Seal Diet Hasn't Changed...Their Body Condition Is Best After Sea Ice Breaks Up

New Research: Polar Bears’ Seal Diet Hasn’t Changed…Their Body Condition Is Best After Sea Ice Breaks Up

Share this…FacebookTwitterThe perspective that polar bears  are endangered by global warming because reduced sea ice limits their seal-hunting opportunities is contradicted by observations of (a) polar bears thriving (body condition) during melt season, and (b) no trends in reduced seal consumption by polar bears in the 21st century. From the 1880s to 1940s, the Arctic’s […]
