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 […]

Can’t Be CO2! Scientists Surprised, Discover Mississippi Basin Was Almost 4°F WARMER 700 Years Ago

Another paleo-climatological study reveals that the Mississippi river basin was 2°C warmer than today 700 years ago, another indication that the Medieval Warm Period (MWP) was warmer globally than today. This is bad news for the zealot backers of the man-made global warming hypothesis. Today as atmospheric CO2 concentrations climb beyond 400 ppm, climate alarmists […]

New Study: Coral Bleaching ‘Repeatedly Occurred’ Throughout The Warmer-Than-Today Mid-Holocene

Mid-Holocene South China Sea maximum temperatures were ~3.5°C warmer (33.5°C vs. today’s 29.9°C) about 5000 yrs ago, when corals experienced an “optimum coral growth period”. There were “numerous coral bleaching episodes” even when temperatures weren’t as high, as coral bleaching is naturally occurring. Key points from a  new study (Wang et al., 2021) that throws […]

Proof Of Warmer Earlier Climate! Swiss Geologist Studies 10,800-Year Old Tree Trunk Under Alps Glacier

Previously hidden under a Swiss glacier, a 10,800-year old tree trunk was discovered and tells us the Alps were much warmer in the early Holocene than today. Online SRF Swiss Broadccasting recently reported on a fascinating find in the Swiss Alps: a more than 10,000 year old tree trunk that had been until recently buried […]

What Global Warming? 148 New (2020) Scientific Papers Affirm Recent Non-Warming, A Degrees-Warmer Past

Scientists continued defying the “unprecedented” global warming narrative by publishing nearly 150 papers  in 2020 that show large regions of the Earth (a) haven’t warmed in recent decades, (b) were as-warm or warmer within the last several centuries, and/or (c) were 1-7°C warmer than today just a few millennia ago. Here is the link to […]

Huge Database Of Studies Documenting Meters-Higher Mid-Holocene Sea Levels Swells Again In 2020

In 2020, scientists continued to publish papers affirming global sea levels are today about 2 meters lower than they were a few thousand years ago. During the last interglacial (~116 to 128 thousand years ago), when CO2 peaked at just 280 ppm but surface temperatures were so much warmer that much less water was locked […]

Dozens Of Scientists Reveal Most Of The Planet Is COLDER TODAY Than Most Of Past 8000 Years

Undisputed temperature reconstructions from around the world show the planet was much warmer over most of the Holocene (past 10,000 years) than it is today.  Kenneth recently wrote how 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.  Only the […]

New Research Shows The Oceans Can ‘Spontaneously’ Warm 8°C In Under 100 Years ‘Without External Trigger’

Scientists are increasingly finding that abrupt, decadal-scale temperature changes of multiple degrees Celsius can arise unforced and spontaneously. The surface temperatures for the Greenland ice sheet have been known to warm 8 to 16°C “within decades or less” – yes,  fewer than 10 years – due to “unforced oscillations.” In other words, no external forcing […]

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 […]

Scientists: Antarctica Ice Sheet Thinned 400 Meters 5000 Years Ago, And Natural Oceanic Cycles Drive Climate

Today we present two papers on climate reconstruction using proxy data. One about East Antarctica and the other about belize. Hat-tip reader Mary Brown. AMO behind sea surface temperatures First we look at a paper authored by a team of German scientists: “Great Blue Hole (Lighthouse Reef, Belize): A continuous, annually-resolved record of Common Era […]
