Scientists Admit Cloud Radiative Properties Are 3D But Studies 'Ignore' This And Use 1D Simulation Data

Scientists Admit Cloud Radiative Properties Are 3D But Studies ‘Ignore’ This And Use 1D Simulation Data

Modeling the main factors driving climate is riddled with and precluded by observational error. Some scientists now acknowledge this. Clouds are a main factor – even the “most important factor” – controlling changes in the Earth’s radiation budget, or climate (Sfîcă et al., 2021, Lenaerts et al., 2020).

Reminder: Historical Natural Warming Rates Dwarf Modern Climate Change

Reminder: Historical Natural Warming Rates Dwarf Modern Climate Change

Greenland has not warmed (net) in the last 90 years. From 80,000 to 20,000 years ago Greenland warmed by 10-15 Kelvin within a span of “a few decades” 24 times (Kypke and Ditlevsen 2024). These abrupt warming periods occurred without concomitant CO2 concentration changes. And, of course, without human interference. Image Source: Kypke and Ditlevsen […]

Central Italy Was 3-4°C Warmer Than Today About 10,000 to 12,000 Years Ago

Central Italy Was 3-4°C Warmer Than Today About 10,000 to 12,000 Years Ago

In a new study, scientists use the new “ostracod-clumped isotope thermometer” to reconstruct a much warmer Late Pleistocene/Early Holocene Mediterranean climate. Today’s average summer and winter temperatures are 22°C (21.4°C) and 8°C, respectively, at Central Italy’s Lake Trasimeno. Around 11,000-12,000 years ago, when CO2 hovered in the 220-230 ppm range, summer temperatures averaged 25°C, sometimes […]

New Study: Large Atmospheric Pressure Swings May Explain Past Hothouse-Icehouse Climates, CO2 Levels

New Study: Large Atmospheric Pressure Swings May Explain Past Hothouse-Icehouse Climates, CO2 Levels

Atmospheric pressure may have been over 2.0 bar during the Jurassic, which may explain why Antarctica was a densely vegetated rainforest during that time. It has long been understood that atmospheric pressure is one of the primary determinants of a planet’s temperature, with higher pressure (for example, Venus at 92 bar) yielding warmer climates due […]

New Study: East Antarctica's Ice Sheet Thickening, Gaining Mass - Especially Since The 1980s

New Study: East Antarctica’s Ice Sheet Thickening, Gaining Mass – Especially Since The 1980s

A collection of 85-year-old photographs reveal “growth and stability” of the East Antarctic ice sheet. Per a new study, more than 2200 historical aerial photos of a 2000 km stretch of ice in East Antarctica have been recently uncovered. The rare images reveal what the glaciers in this region looked like in 1937. Interestingly, the […]

New Study: Western Greenland Was '1.5-2°C Warmer Than Today' During Medieval Warm Period

New Study: Western Greenland Was ‘1.5-2°C Warmer Than Today’ During Medieval Warm Period

A new West Greenland temperature reconstruction (Strunk et al., 2024) finds the region was 1.5 to 2°C warmer than today from 560 to 1100 CE, encompassing the Medieval Warm Period (MWP). The LOI (vegetation abundance) record reflects a much wetter, greener landscape during the MWP. Image Source: Strunk et al., 2024

The Claim 'Exxon Knew' Their Products Induced 'Catastrophic Climate Impacts' In The 1970s Is Bunk

The Claim ‘Exxon Knew’ Their Products Induced ‘Catastrophic Climate Impacts’ In The 1970s Is Bunk

In the 1970s and 1980s ExxonMobil did not know that their reports would be so wrongly misinterpreted in the 2010s. Since 2015, when “investigative journalists” uncovered reports written in the late 1970s by ExxonMobil’s Science Advisor J.P. Black, it has been a common talking point in alarmist circles to insist that “Exxon Knew” about the […]

Megafossil Carbon Dating Indicates Sweden Was 2-3°C Warmer Than Today During The Last Glacial

Megafossil Carbon Dating Indicates Sweden Was 2-3°C Warmer Than Today During The Last Glacial

“Modern warming is within natural Holocene climate variability” – Kullman and Öberg, 2024 From about 16,800 to 6000 years ago warmth-dependent tree species grew 300-700 altitudinal meters higher than they do today on Mt. Åreskutanthan, Swedish Scandes. Due to the well-known warmth threshold for boreal tree species and the lapse rate (0.6°C per 100 m), […]

New Study: China's Loess Plateau 7-8°C Warmer Than Today For Much Of The Last 4000 Years

New Study: China’s Loess Plateau 7-8°C Warmer Than Today For Much Of The Last 4000 Years

Scientists refer to the Middle and Late Holocene’s much warmer and wetter regional climate as “favorable,” “optimal” and “the best.” New research from a Loess Plateau study site identifies mean annual temperatures as 9.86°C today, while annual precipitation averages 531 mm. These values are shown to be among the coldest and driest of the last […]

New Study: Warming Temperatures In China The 'Main Factor' Explaining Rising Crop Yields

New Study: Warming Temperatures In China The ‘Main Factor’ Explaining Rising Crop Yields

In what shouldn’t even be news, scientists have discovered warmth and rising CO2 are beneficial to crops, whereas cold and falling CO2 lead to declines in crop production. Scientists have determined the “main factor” directly improving post-1960 crop yields across China is a warming climate (Chen and Sun, 2024). Warming expands the growth area for […]

HadCRUT Has Now Fully Removed 0.15°C From The 1940s Warmth 'Blip' As Proposed In 2009 E-mails

HadCRUT Has Now Fully Removed 0.15°C From The 1940s Warmth ‘Blip’ As Proposed In 2009 E-mails

The amplitude of the recorded warmth in the 1940s was always a problem for purveyors of the human-caused global warming narrative. So the 1940s temperatures have been artificially cooled to make this less of a problem. In 2009, overseers of the HadCRUT global temperature data discussed “correcting” the “1940s warming blip” in e-mails that they […]

New Study Finds An Extremely Low CO2 Climate Sensitivity For The Arctic And Antarctic

New Study Finds An Extremely Low CO2 Climate Sensitivity For The Arctic And Antarctic

The phenomenon of increasing the concentration of greenhouse gases (water vapor, carbon dioxide, methane) is assumed to lead to sharply rising temperatures in polar regions, or “polar amplification.” As it turns out, it doesn’t. Per a new radiative forcing model (Notholt et al., 2024), increasing CO2 from pre-industrial to present levels (278 to 400 ppm) […]
