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

Share this...

Share this…FacebookTwitterScientists 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 […]

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

Share this...

Share this…FacebookTwitterIn 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 […]

Alarmism Dies In The Great Barrier Reef As New Study Documents Reef Growth Since The 1970s

Share this…FacebookTwitterA new study affirms coral reefs grow when seas are warm and rising. Growth “shuts off” during colder, falling sea level periods. Consequently, the Great Barrier Reef has experienced growth in the last 150 years – especially in recent decades. During the Last Glacial Maximum (~30,000 to 15,000 years ago), when Great Barrier Reef […]

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

Share this...

Share this…FacebookTwitterUndisputed 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 […]

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

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

Share this…FacebookTwitterScientists 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 […]

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…FacebookTwitterScientists report they must “exclude atmospheric pCO2 as a direct driver of SST variations” after finding the Atlantic Ocean’s surface was multiple degrees warmer than today from 90 to 20 thousand years ago, or when CO2 concentrations hovered below 200 ppm.  Another new study (Hou et al., 2020) casts even more doubt on the […]

New Study Finds CO2 Reached 1980s-2000s Levels About 4,000 Years Ago In Japan

New Study Finds CO2 Reached 1980s-2000s Levels About 4,000 Years Ago In Japan

Share this…FacebookTwitterCO2 reached 1980s (352 ppm, average) to 2000s (380 ppm, max) levels 2500-5500 years ago in Japan per stomata records. Scientists (Wang et al., 2020) have determined stomatal evidence can uncover large short-term CO2 fluxes of 50-100 ppm within a century or less. Measurements from a forest near Mt. Kurikoma, Japan, reveal minimum to […]

Past Climate More Complex Than Previously Thought, Says Germany’s Alfred Wegener Institute

Share this...

Share this…FacebookTwitterAtmospheric CO2 just doesn’t change on a whim and cause global temperature to follow along in response.  Press release from The Alfred Wegener Institute (AWI): Irregular Appearances of Glacial and Interglacial Climate States During the last 2.6 million years of Earth’s climate has altered between glacial and interglacial states. As such, there have been […]

Share this…FacebookTwitterReconstructions of past temperatures show much colder periods with higher CO2 levels or as-warm or warmer periods with much lower CO2 levels. A new study (Paus, 2020) indicates modern July temperatures center around 7.5 to 8°C in the Scandes Mountains (Norway). Today’s CO2 atmospheric concentration has reached 410 ppm. During the latter stages of […]

A new study (Cherezova et al., 2020) […]
