Yet Another Model-Based Claim Of Anthropogenic Climate Forcing Collapses

Yet Another Model-Based Claim Of Anthropogenic Climate Forcing Collapses

Share this...

Share this…FacebookTwitterHigh-resolution climate models have projected a “decline of the Atlantic Meridional Overturning Circulation (AMOC) under the influence of anthropogenic warming” for decades (Lobelle et al., 2020). New research that assesses changes in the deeper layers of the ocean (instead of “ignoring” these layers like past models have) shows instead that the AMOC hasn’t declined […]

New Study Finds A 79% Rise In Polar Bear Sightings Since 2005 As Their Arctic Habitat Dramatically Expands

New Study Finds A 79% Rise In Polar Bear Sightings Since 2005 As Their Arctic Habitat Dramatically Expands

Share this…FacebookTwitterResearch on polar bear sightings using a systematic “regional marine mammal sightings programme” during 2005-2018 reveals there were 1,433 polar bears sightings from 2005-2011 compared to 2,569 during 2012-2018 around Svalbard. The perspective that polar bears  are endangered by global warming because reduced sea ice limits their seal-hunting opportunities is  again contradicted by real-world […]

More Evidence Surfaces That Fires Are Far Less Common Today Than In The Past

More Evidence Surfaces That Fires Are Far Less Common Today Than In The Past

Share this...

Share this…FacebookTwitterTwo new studies suggest fires in Australia and the northwestern US raged with great frequency and regularity until 500 to 900 years ago, when fire records rapidly declined to the present. In the Northern Territory of Australia the highest fire incidence ~4600 to 4000 years before present co-occurred during a time of “high effective […]

New Study Finds 25-45% Of The Instrumental Warming Since The 1950s Is Due To Urbanization, Not CO2

New Study Finds 25-45% Of The Instrumental Warming Since The 1950s Is Due To Urbanization, Not CO2

Share this…FacebookTwitterWhy have sea surface temperatures and proxy temperature reconstructions so strongly diverged from the instrumental land record in recent decades? Because “0.36 ± 0.04 °C” of non-climatic warming from roofs, asphalt, machines, vehicles…artificially enhances the post-1950s global temperature trend. A new analysis (Scafetta, 2021) suggests: • Urban Heat Island (UHI) effects can raise city temperatures 6-9°C […]

Share this…FacebookTwitterThe 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; […]

The Globe's Total Greenhouse Effect Forcing Has Been On A Declining Trend For Decades

The Globe’s Total Greenhouse Effect Forcing Has Been On A Declining Trend For Decades

Share this...

Share this…FacebookTwitterCO2’s impact on the total net greenhouse effect (GHE) or longwave (LW) forcing trend has been offset by the dominant impact of cloud cover since the 1980s.  It is now widely accepted that changes in clouds, naturally driven by changes in atmospheric circulation, “may be the most important parameter controlling the radiation budget, and, […]

Robust Measurements Show The Northern Hemisphere's Atmosphere Cooled -0.6°C In 5 Years 60 Years Ago

Robust Measurements Show The Northern Hemisphere’s Atmosphere Cooled -0.6°C In 5 Years 60 Years Ago

Share this…FacebookTwitterCovering 92% of the Northern Hemisphere’s (NH) atmosphere, between 150,000 and 200,000 measured temperatures per month indicated the NH cooled by -0.60°C from 1958-1963. From the equator to 30°N, the cooling was -0.81°C. Climate activists have since eliminated this cooling from the record. Image Source: Starr and Oort, 1973 Temperature measurements indicating the NH […]

Molecular Physicist's New Publications Add To The List of Over 130 Low CO2 Climate Sensitivity Papers

Molecular Physicist’s New Publications Add To The List of Over 130 Low CO2 Climate Sensitivity Papers

Share this...

Share this…FacebookTwitterSeveral more estimates of extremely low CO2 climate sensitivity have been added to the database in the last year. The collection of scientific papers that assess a very low (under 1°C for a doubling of CO2) or a non-quantified, but negligible climate sensitivity has swelled to over 130. In 2015, when it was first published, […]

Share this…FacebookTwitter In 2020, more than 400 scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. Over 400 scientific papers […]

Scientists Find CO2 Levels Must TRIPLE To Have An 1800% Smaller Climate Impact Than Clouds Do

Scientists Find CO2 Levels Must TRIPLE To Have An 1800% Smaller Climate Impact Than Clouds Do

Share this…FacebookTwitterOceans cover 71% of the Earth’s surface. An analysis of CO2’s radiative effect on ocean temperatures finds CO2 forcing is negligible even after reaching a concentration of 1,071 ppm. In the tropical oceans, 500 to 1,000 W/m² of solar radiation uniformly heats the first 2 meters of the ocean surface by 2 Kelvin in […]

Another New Study Says Warming And CO2-Induced Greening Leads To COOLING Of Land Surface Temperatures

Share this...

Share this…FacebookTwitterSince the 1980s, warming and rising CO2 fertilization have spawned a global-scale greening trend. This leads to an “Earth greening-induced cooling effect” of land surface temperatures. In the last 9 months we have highlighted a study (Haverd et al., 2020) asserting rising CO2 and warming are the dominant drivers of Earth’s strong post-1980s greening […]

Share this…FacebookTwitterMid-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 […]
