More Research Affirms The Human Role In Global Warming Has Been Strongly Overestimated

AGW proponents use subjective forcing models and unmeasured estimates of past solar activity to claim humans drive warming. A scientist’s (Larminat, 2023) reassessment finds the Sun can drive climate, equilibrium climate sensitivity (ECS, 2xCO2 + feedbacks) is 1.14°C, and human forcing is overestimated. Because there have been no direct measurements of solar activity until the […]

The Narrative That Polar Bears Need Sea Ice To Catch Prey Has Collapsed As More Evidence Piles Up

The Narrative That Polar Bears Need Sea Ice To Catch Prey Has Collapsed As More Evidence Piles Up

Arctic regions with 6+ months of sea ice coverage today were ice-free nearly year-round 9,000 to 5,000 years ago (2°C warmer) and 130,000 to 115,000 years ago (7-8°C warmer). And yet polar bears survived these periods. Per a new study, today’s Scandinavian Arctic climate is so cold it is actually “comparable” to that of the […]

Paleoclimate Reconstructions Continue To Document A Much Warmer-Than-Today Holocene

Paleoclimate Reconstructions Continue To Document A Much Warmer-Than-Today Holocene

According to a new study, eastern Mediterranean summer temperatures were 1.5°C to 3°C “greater than the present” from about 11,000 to 7,000 years ago, when CO2 levels were approximately 265 ppm. Then the temperatures “followed a gradual decline towards present-day conditions”. “The MTWA also showed an increasing trend from 9 ka and reached a maximum of […]

2 More New Studies Undermine Alarmist Claims That Corals Are Harmed By Warming

2 More New Studies Undermine Alarmist Claims That Corals Are Harmed By Warming

Warmer sea surface temperatures are associated with coral growth, not decline. According to a new study, coral growth was slow during the ~1°C colder Little Ice Age (LIA), but grew rapidly as sea surface temperatures (SSTs) warmed after 1850. Warmth is associated with coral growth, whereas colder SSTs are linked to growth rate decline. “The […]

New Study Now Claims We Humans Heat The Atmosphere Just By Exhaling

New Study Now Claims We Humans Heat The Atmosphere Just By Exhaling

“Where hydrocarbon chains (food types) are consumed by humans and turned into CH4 [methane] … global warming potential is no longer neutral, and human respiration has a net warming effect on the atmosphere.”  – Prada et al., 2023 Image Source pexels.com (stock photo) According to a new study, humans “contribute to global warming” by exhaling […]

From Now To 2100 Emission Reduction Policy Costs Greatly Exceed Any Net Benefit From Averted Warming

From Now To 2100 Emission Reduction Policy Costs Greatly Exceed Any Net Benefit From Averted Warming

The benefits of not meeting Paris Accord emissions-reduction targets outweigh the costs associated even with worst-case-scenario global warming throughout the 21st century. A new comprehensive analysis (Tol, 2023) weighs the cost-benefit of meeting Paris Accord emission policy targets to keep global warming in check, or under 2°C. The analysis reveals that even in the best […]

SE Asian Sea Levels Were 3-4 Meters Higher Than Today 7-4 Thousand Years Ago

SE Asian Sea Levels Were 3-4 Meters Higher Than Today 7-4 Thousand Years Ago

Comprehensive data analysis shows relative sea levels were anywhere from 1 to 7 meters (~3.9 m) higher than present throughout the Mid-Holocene at 15 of 16 assessed sites across Southeast Asia. A new study (Li et al., 2023) compiles highstand records from sites spanning Thailand, Vietnam, Singapore, Malaysia, Borneo, Sunda Shelf, Makassar Strait…and indicates that […]

Another Day, Another Scientific Paper Insists 'Global Warming Is Not Caused By Increased CO2'

Another Day, Another Scientific Paper Insists ‘Global Warming Is Not Caused By Increased CO2’

“…the rate of change in CO2 concentration is controlled, not by emissions, but by the global temperature” – Emrén, 2023 A new study published in the International Journal of Global Warming once again questions the popular narrative that says humans can control the temperatures of the ocean and melt the polar ice sheets by engaging […]

New Study: The 'Global Tropics As A Whole' Were As Warm Or Warmer Than Today 10,000 Years Ago

New Study: The ‘Global Tropics As A Whole’ Were As Warm Or Warmer Than Today 10,000 Years Ago

“…by about 10 kyr ago, regional MST values consistently approached or exceeded today’s value of about 23°C” – Baxter et al., 2023 According to a new temperature reconstruction published in Nature, the Horn of Africa and “global tropics as a whole” were “1.6°C warmer than today” throughout the Early and Middle Holocene. This is “consistent […]

New Study: 67% Of Scientific Papers Can Be Said To Reject The AGW Hypothesis…

…when using the same assumption-based methodology to arrive at the conclusion only 0.5% of scientific papers reject AGW. In a new study, six scientists (Dentelski et al., 2023) effectively eviscerate a methodologically flawed 2021 study (Lynas et al.) that claims 99.53% of 3,000 scientific papers examined (by subjectively classifying papers based only on what is […]

New Study Finds The Post-1900 CO2 Rise Has Not Discernibly Altered The Greenhouse Effect

New Study Finds The Post-1900 CO2 Rise Has Not Discernibly Altered The Greenhouse Effect

Variations in the greenhouse effect are predominantly modulated by water vapor and cloud cover. CO2’s role in the greenhouse effect is so minor it cannot be discerned. For decades scientists have reported that a CO2 concentration of about 300 ppm can only increase the downwelling longwave radiation (DLWR), or greenhouse effect, by about 1.5 W/m² […]

New Study: CO2 Emission Rates From Natural Sources Are Up To 6 Times Larger Than From Humans

New Study: CO2 Emission Rates From Natural Sources Are Up To 6 Times Larger Than From Humans

Analysis of CO2 residence times suggest 65% to 96.5% of the CO2 concentration increase since 1958 is natural. According to a new study, the claim that increases in atmospheric CO2 are driven exclusively by humans relies on a made-up, disparate accounting model, with the residence time for natural emissions 3 to 4 years (which is […]
