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...

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...

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...

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...

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...

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...

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...

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.

Magnitude Of Recent Surface Solar Radiation Forcing Over US Is Tens Of Times Greater Than From CO2

Magnitude Of Recent Surface Solar Radiation Forcing Over US Is Tens Of Times Greater Than From CO2

Share this...

Share this…FacebookTwitterOver the US, the modest change in cloud cover from 1996-2019 predominantly drove the +11.77 W/m² surface solar radiation forcing during 1996-2012 (then -2.35 W/m² from 2013-2019). These “brightening” and “dimming” magnitudes easily overwhelm the values associated with an annual 2 to 2.5 ppm rise in CO2 forcing (0.2 W/m² per decade). When cloud […]

Paradigm-Busting New Study Affirms CO2 Doesn't Drive Climate - Water, Clouds Do

Paradigm-Busting New Study Affirms CO2 Doesn’t Drive Climate – Water, Clouds Do

Share this...

Share this…FacebookTwitterA professor of hydrology from the University of Athens eviscerates the “naïve” paradigm that says the natural state of Earth’s climate is constancy and stability, only changing when an “external agent” (i.e., a rapid increase in fossil fuel emissions ) acts upon it. Instead, (a) water is the main element driving climate and (b) […]

Scientists Continue To Affirm Rising Incoming Solar Radiation Drives Recent Warming In Europe

Scientists Continue To Affirm Rising Incoming Solar Radiation Drives Recent Warming In Europe

Share this...

Share this…FacebookTwitterTwo new studies refer to the natural decline in cloud and aerosol reflectivity and consequent rise in incoming solar radiation or sunlight duration as the explanation for warming trends across Europe. CO2 is not even mentioned as a factor in climate change. Scientists point out that, for Europe, “the decrease in cloud cover is […]

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

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, […]

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 […]
