'A Significant And Robust Cooling Trend' In The Southern Ocean From 1982–2020 Defies Climate Models

‘A Significant And Robust Cooling Trend’ In The Southern Ocean From 1982–2020 Defies Climate Models

Share this…FacebookTwitterA new study reports there has been a -0.3°C cooling in the Southern Ocean since 1982 per multiple observational data sets. The authors detail the “failure of CMIP5 models in simulating the observed SST cooling in the Southern Ocean.” The Southern Ocean is today about 1-2°C colder than it has been for nearly all […]

Alarmists: Clouds May 'Disappear Forever' With Warming. Observations: Clouds Increase As It Warms.

Alarmists: Clouds May ‘Disappear Forever’ With Warming. Observations: Clouds Increase As It Warms.

Share this…FacebookTwitterA new study finds the modeling-based claim that cloud cover changes are only responding to anthropogenic CO2 forcing as a feedback – and not functioning independently as a forcing – has (again) been contradicted by observations. Since this is a water planet, and since clouds are formed when water vapor turns into water droplets, […]

2 More New Studies Reaffirm The CO2-Drives-Climate-Change Paradigm Has A Magnitude Problem

2 More New Studies Reaffirm The CO2-Drives-Climate-Change Paradigm Has A Magnitude Problem

Share this…FacebookTwitterIt takes 10 years and 22 ppm for CO2 to amass just 0.2 W/m² in total surface energy flux. In contrast, short-wave cloud radiative forcing fluctuations vary in amplitude by ±300 W/m² within hours. Earth’s surface energy imbalance is said to have been positive, +0.6 W/m², during the first decade of this century (Stephens […]

Hundreds More Papers Published In 2021 Support A Skeptical Position On Climate Alarm

Share this…FacebookTwitterIn 2021, several hundred more 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. These scientific papers affirm the […]

2021: The Year Scientists Increasingly Ascribed Shortwave-Modulating Cloud Variability As A Climate Driver

2021: The Year Scientists Increasingly Ascribed Shortwave-Modulating Cloud Variability As A Climate Driver

Share this…FacebookTwitter“Clouds may be the most important parameter controlling the radiation budget, and, hence the Earth climate.” –  Sfîcă et al., 2021 It has become more and more common for scientists to attribute modern radiation budget (climate) changes to variations in cloud cover. This should not be surprising. It’s been pointed out (van Heerwaarden et […]

Great Barrier Reef Warming, Coral Bleaching Driven By Cloud Radiative Forcing, Not Humans

Great Barrier Reef Warming, Coral Bleaching Driven By Cloud Radiative Forcing, Not Humans

Share this…FacebookTwitterFor decades Great Barrier Reef (GBR) warming and coral bleaching have often been assumed to be driven by human greenhouse gas emissions and/or El Niño events. But a new study finds a much larger and more robust correlation between natural cloud cover modulation of solar radiation, shallow-water warming, and bleaching. It has taken over […]

The 'Hypothesis' That Longwave (Greenhouse Gas) Forcing Drives Greenland Ice Melt Is Wrong

The ‘Hypothesis’ That Longwave (Greenhouse Gas) Forcing Drives Greenland Ice Melt Is Wrong

Share this…FacebookTwitterScientists publishing in GRL once again affirm that in recent decades the dominant mechanism driving surface melt for the Greenland ice sheet has been downwelling shortwave radiation modulated by clearer skies (fewer clouds) and natural wind pattern changes. Greenland’s ice melt has not been driven by “longwave heating” from greenhouse gases in the last […]

In A Few Days Clouds Affect Earth's Radiation Budget By More Than CO2 Does In 270 Years

In A Few Days Clouds Affect Earth’s Radiation Budget By More Than CO2 Does In 270 Years

Share this…FacebookTwitterScientists continue to affirm the critical role of clouds in modulating the Earth’s energy budget, and, hence, the climate. The total net forcing of the entirety of the CO2 influence on climate has been less than 2 W/m² since 1750 (Feldman et al., 2015). Image Source: Feldman et al., 2015 On a per-decade basis, a […]

2001-2019 Warming Driven By Increases In Absorbed Solar Radiation, Not Human Emissions

2001-2019 Warming Driven By Increases In Absorbed Solar Radiation, Not Human Emissions

Share this…FacebookTwitterThree new studies affirm the increase in absorbed solar radiation associated with decreased reflection by clouds (albedo) has been the “root cause” of the positive Earth Energy Imbalance and global warming since the early 2000s. Scientists (Loeb et al., 2021) have determined the rather uncertain positive trend in Earth’s Energy Imbalance (EEI) from 2005 […]

Thunderous New “Atmosphere” Publication: “Warming Of Last 20 Years Mainly Caused By Cloud Changes”

Share this…FacebookTwitterScience never quits. New findings by German researchers challenge IPCC claim that greenhouse gases have driven recent warming. Data point to low cloud cover changes.  =================================== Warming of the last 20 years mainly caused by cloud cover changes By Fritz Vahrenholt and Hans-Rolf Dübal (Translated, edited and subheadings by P. Gosselin) Hans-Rolf Dübal and […]

New Study Inadvertently Slays The Narrative: Emissions Reductions From Lockdowns Added WARMING!

New Study Inadvertently Slays The Narrative: Emissions Reductions From Lockdowns Added WARMING!

Share this…FacebookTwitterIt has been assumed COVID lockdowns and their associated reductions in human CO2 emissions would be a “step in the right direction” with regard to climate change mitigation. But a new study finds the particulate (aerosol) pollution reductions from less industrial and transportation activity in Europe during the months of March to May (2020) […]

Models In Turmoil: Underestimation Of Satellite-Based Cloud-Aerosol Interaction "Hampering Climate Change Projections"

Models In Turmoil: Underestimation Of Satellite-Based Cloud-Aerosol Interaction “Hampering Climate Change Projections”

Share this…FacebookTwitterClimate scientists have been underestimating the role of aerosol-cloud interactions, a new study suggests, thus again throwing climate models into disarray… accurate future climate projections unlikely. A new paper by Hailing et al appearing in Nature Communications found a “significant underestimation of radiative forcing by aerosol–cloud interactions derived from satellite-based methods.
