Detection Of A CO2 Climate Signal In Radiative Forcing Is Again Foiled By Clouds

Detection Of A CO2 Climate Signal In Radiative Forcing Is Again Foiled By Clouds

Share this… Facebook TwitterIt so difficult to constrain errors in identifying the cloud impact on Earth’s radiation budget that the orders-of-magnitude smaller radiative impact of CO2 cannot be distinguished from noise. According to a new study using CERES data, the observed biases in detecting the radiative effects of clouds on climate are 2.5 to 6.25 […]

Scientists: Only 10% Of The 1984-2017 Greenhouse Gas (Longwave) Forcing Was From CO2

Scientists: Only 10% Of The 1984-2017 Greenhouse Gas (Longwave) Forcing Was From CO2

Share this… Facebook TwitterA late 2021 study finds water vapor and temperature changes accounted for 90% of the changes in clear-sky downwelling longwave or greenhouse effect forcing since the mid-1980s. CO2 forcing assumed a mere bit-player role. The seminal Feldman et al. (2015) study concluded it takes 10 years and a 22 ppm increase in […]

New Study: A Post-2000 Increase In Absorbed Solar Energy 'By Far The Largest Contribution' To Warming

New Study: A Post-2000 Increase In Absorbed Solar Energy ‘By Far The Largest Contribution’ To Warming

Share this… Facebook TwitterScientists have once again affirmed the 2000-2020 total greenhouse effect (longwave) forcing has been declining in recent decades just as absorbed solar radiation has been increasing due to cloud albedo modulation. The latter explains the net positive Earth Energy Imbalance (EEI) and consequent global warming during this period. Recently we detailed the […]

Scientists: The Global Warming Since 1985 Cannot Be Attributed To CO2 Forcing

Scientists: The Global Warming Since 1985 Cannot Be Attributed To CO2 Forcing

Share this… Facebook TwitterCloud modulation of shortwave radiation and greenhouse effect forcing has largely been the determining factor in the global warming of the last 45 years. Not CO2. CO2 forcing and its effect on surface temperatures is detailed in analyses of changes in clear-sky radiation only because all-sky radiation effects that include clouds (and […]

'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… Facebook TwitterA 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 […]

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… Facebook TwitterA 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 […]

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… Facebook TwitterIt 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 […]

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

Share this… Facebook TwitterIn 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 […]

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… Facebook Twitter“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 […]

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… Facebook TwitterFor 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 […]

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… Facebook TwitterScientists 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 […]

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… Facebook TwitterScientists 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 […]
