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 […]

New Study: Modern Sea Ice Extent Is Nearly The Highest In 9000 Years Across the Arctic

New Study: Modern Sea Ice Extent Is Nearly The Highest In 9000 Years Across the Arctic

Millennial-scale Arctic sea ice reconstructions do not corroborate alarmist claims of unprecedented sea ice losses in modern times.  Using sea ice biomarker proxy (IP25), scientists (Kolling et al., 2023) have determined that the sea ice extent in the Labrador Sea was nearly absent throughout the year (close to 0.0 μg/gTOC) for much of the last […]

New Study: Antarctic Sea Ice Completed Half Its Deglacial Retreat 1000s Of Years Before CO2 Began Rising

New Study: Antarctic Sea Ice Completed Half Its Deglacial Retreat 1000s Of Years Before CO2 Began Rising

The timing of the dramatic Antarctic sea ice decline during the last deglaciation suggests solar forcing and sea ice retreat “instigated” century-scale climate warming and atmospheric CO2 change. This would appear to challenge the perception CO2 plays a causal role in glacial-interglacial sea ice and climate changes. From ~21,000 to 19,500 years ago, when CO2 […]

New Study: East Asian Sea Ice Extent Increasing Since 2005 ... Region Is Now Colder Than 1700s-1800s

New Study: East Asian Sea Ice Extent Increasing Since 2005 … Region Is Now Colder Than 1700s-1800s

Yet another region of the world fails to cooperate with “global” warming instructions. New research (Zhang et al., 2023) finds the sea ice extent has undergone an overall increasing trend from 2005-2021 in the Sea of Japan, Yellow Sea, and Bohai Sea. “Over the past 17 years, the maximum sea ice extent in the marginal […]

Scientists: Nearly 4 Decades Of Climate Model Failure Undermines Confidence In Future Predictions

Scientists: Nearly 4 Decades Of Climate Model Failure Undermines Confidence In Future Predictions

IPCC models rooted in assumptions that we humans can and do control the Atlantic Ocean’s circulation with our daily-activity CO2 emissions have been wrong since the mid-1980s. Why should we still believe in them? The latest IPCC report continues to say it is “very likely” the Atlantic Meridional Ocean Circulation (AMOC), a fundamental climate parameter, […]

New Study Finds Most Of Antarctica Has Cooled By Over 1°C Since 1999...W. Antarctica Cooled 1.8°C

New Study Finds Most Of Antarctica Has Cooled By Over 1°C Since 1999…W. Antarctica Cooled 1.8°C

Significant 21st century cooling in the Central Pacific, Eastern Pacific, and nearly all of Antarctica “implies substantial uncertainties in future temperature projections of CMIP6 models.” – Zhang et al., 2023 New research indicates West Antarctica’s mean annual surface temperatures cooled by more than -1.8°C (-0.93°C per decade) from 1999-2018. In spring, the West Antarctic Ice […]

A 'Major Surprise' Nature Study Finds Phasing Out Fossil Fuels Will Lead To Decades Of Warming

A ‘Major Surprise’ Nature Study Finds Phasing Out Fossil Fuels Will Lead To Decades Of Warming

“We would expect from a 100% switchover from fossil fuels to zero-emission renewables…net radiative heating would increase drastically.” – Nair et al., 2023 Using observational data gleaned from COVID-19 lockdowns in South Asia, scientists publishing in a Nature journal (Nair et al., 2023) have now determined the ongoing switch to zero greenhouse gas (GHG) emissions […]

New Study: Lower Bound Uncertainty In Aerosol Forcing 10 Times Larger Than 10 Years Of CO2 Forcing

New Study: Lower Bound Uncertainty In Aerosol Forcing 10 Times Larger Than 10 Years Of CO2 Forcing

“Despite two decades of advances in many aspects of aerosol-climate science, aerosol climate forcing uncertainty is virtually undiminished. Yet, reducing this uncertainty is critical for any effort to attribute, mitigate, or predict climate changes.” – Kahn et al., 2023 According to a new study, the lower-bound uncertainty in natural aerosol forcing from wildfire smoke, desert […]

New Reconstructions From Brazil, China, Europe Indicate No Net Warming In Recent Centuries

New Reconstructions From Brazil, China, Europe Indicate No Net Warming In Recent Centuries

Paleoclimate studies continue to undermine claims of “unprecedented” global warming in the modern era. A new temperature reconstruction (Oliveira Silva Muraja et al., 2023) for Brazil reveals there has been no net modern warming since the 1400s. Image Source: Oliveira Silva Muraja et al., 2023 Another new temperature reconstruction (Yue et al., 2023) indicates there […]

Physicists: CO2 Only Affects 10% Of IR In 3% Of The Troposphere

Physicists: CO2 Only Affects 10% Of IR In 3% Of The Troposphere

There are many scientifically invalid assumptions in the “greenhouse gas hypothesis” that the editors of a journal, Earth System Dynamics (ESD), now insist they will never again allow to be subjected to critical analysis in future publications, as the editors of this journal are committed to only publishing studies agreeing with the “consensus.” In a […]

97,404 Direct CO2 Measurements From 1826-2008 Indicate Humans Do Not Drive CO2 Change

97,404 Direct CO2 Measurements From 1826-2008 Indicate Humans Do Not Drive CO2 Change

Per a new study, atmospheric CO2 levels rose to 383 ppm in the 1940s mostly as a consequence of soil respiration processes and sea surface temperature warming. Any anthropogenic contribution to this CO2 peak “can be largely excluded.” When assessing the historical atmospheric CO2 concentration, direct measurements of chemically analyzed air samples are at least […]
