Glaring Inconsistency In Estimating CO2 vs. Solar Forcing Suggests CO2 Impacts Are Wildly Exaggerated

Glaring Inconsistency In Estimating CO2 vs. Solar Forcing Suggests CO2 Impacts Are Wildly Exaggerated

From about 11,000 to 9,000 years ago the summer solar irradiance absorbed by the Earth’s surface has been estimated to be 40-60 W/m² greater than today from latitudes 40°N to 70°N (Ullman et al., 2015). These values seriously undermine the claim CO2 is the driver of climate change. Image Source: Ullman et al., 2015 Despite […]

German Physicist: Human CO2 Emissions Responsible For 0.05°C Of The Global Warming Since 1750

German Physicist: Human CO2 Emissions Responsible For 0.05°C Of The Global Warming Since 1750

Professor Herman Harde, an environmental physicist, has authored a new position paper on the follies of assuming humans significantly impact the climate. As detailed in his 2017 paper, Dr. Harde concludes the “anthropogenic contribution to the actual CO2 concentration is found to be 4.3% [a figure derived from IPCC AR5], its fraction to the CO2 […]

Analysis Of Data Going Back 40 Years Shows CO2 Has No Effect On Forest Fires,…Burned Area Plummets Since 2000

In a previous post, Trend in Global Fires, data analyst Zoe Phin showed the global fire trend for the last 21 years. Since then, Zoe has taken it it a step further and found a source with more data going back to 1982: from a project funded by European Space Agency. RHere. Actual data is downloaded […]

New Research Applying Scientific Method Shows The Perception CO2 Causes Global Warming 'Can Be Excluded'

New Research Applying Scientific Method Shows The Perception CO2 Causes Global Warming ‘Can Be Excluded’

Instead of focusing on probabilistic percentages and constructed correlations between two events in efforts to determine potential causality, 4 scientists have revisited the requisite conditions for causality in applying the scientific method. They find “the common perception that increasing CO2 causes increased [temperature] can be excluded because it violates the necessary condition for this causal […]

Continued Use Of Combustion Vehicles Leads To 'Much Lower' Lifetime CO2 Emissions Than Driving EVs

Continued Use Of Combustion Vehicles Leads To ‘Much Lower’ Lifetime CO2 Emissions Than Driving EVs

A new study finds “the total CO2 emissions will be much lower with continued use of the old but operational combustion car instead of buying a new electric one.” Image Source: Neugebauer et al., 2022 It has long been assumed that replacing internal combustion engine (ICE) vehicles with electric vehicles (EV) will lead to dramatically […]

EU's 'Carbon Neutral' Policy Of Burning Forests For Fuel Spews 28% More CO2 Emissions Than Burning Coal

EU’s ‘Carbon Neutral’ Policy Of Burning Forests For Fuel Spews 28% More CO2 Emissions Than Burning Coal

“Burning woody biomass increases atmospheric CO2 levels for decades. Burning forest biomass for power generation emits more CO2 per-unit of final energy than burning fossil fuels, including coal.”  – Bloomer et al., 2022 Image Source: IGSD It is scientifically well known that (a) “the carbon emission from wood fuel is bigger by half than that […]

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

It 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 et […]

Defying Modeled Expectations Again: The CO2 Airborne Fraction Has Been Declining Since 1959

Defying Modeled Expectations Again: The CO2 Airborne Fraction Has Been Declining Since 1959

The ratio of the annual CO2 increase divided by the annual fossil fuel emission rate increase is referred to as the “airborne fraction.” It has long been assumed the airborne fraction should increase as fossil fuel emissions increase. But the opposite has happened. Scientists have expressed consternation that the airborne fraction of anthropogenic CO2 emissions […]

Deliberately Alarmist 'The Last Time CO2 Was This High' Claims Are Rooted In Guesswork, Not Science

Deliberately Alarmist ‘The Last Time CO2 Was This High’ Claims Are Rooted In Guesswork, Not Science

Recent reconstructions suggest CO2 concentrations may have ranged between 150 and 600 ppm (or more) throughout the last 4 million years. We routinely see screaming headlines such as CO2 in the Atmosphere Climbs to Highest Level in 4.5 Million Years or Carbon Dioxide Levels Reach Highest Point in Human History. However, these claims that modern […]

Atmospheric Physicist: CO2 Explains 0.1°C Of 1975-2000 Warming - 'One Fifth Of The IPCC Assumption'

Atmospheric Physicist: CO2 Explains 0.1°C Of 1975-2000 Warming – ‘One Fifth Of The IPCC Assumption’

A new study uses existing temperature and CO2 records and albedo/natural variability attribution to suggest most of the recent warming is natural. The climate sensitivity to CO2 forcing is just over 0.2°C for a 100 ppm concentration increase. Dr. Syun-Ichi Akasofu is an “expert in aurora physics, solar physics, geophysics, and magnetosphere” and the founder […]

Higher CO2 Concentrations Mean Better Plant Water Use, Enhanced Photosynthesis, Expanding Sahel

Higher CO2 Concentrations Mean Better Plant Water Use, Enhanced Photosynthesis, Expanding Sahel

William Astley’s comment on CO2 and photosynthesis has been upgraded to a post (subheadings added).  Rich green North German park. Photo by P. Gosselin  Higher CO2 concentrations offer even more advantages By William Astley Better water use by plants In addition to increasing crop yields, increased CO2 enables plants to live in regions were there […]

CO2 A Blessing: Just 1 PPM Increase Means Up To 0.8% Greater Crop Yields, New Study Shows

CO2 A Blessing: Just 1 PPM Increase Means Up To 0.8% Greater Crop Yields, New Study Shows

Higher CO2 means more food, new study confirms As much as the global warming alarmists like to claim that warmer mean global temperatures are nothing but catastrophic, we know that warmer temperatures indeed offer a number of advantages. Source: Food and Agriculture Organization Among them is agricultural output and global greening. Warmer temperatures not only […]
