New Study Finds Global Cities Have Warmed Due To Rising Solar Surface Forcing Since 1986

New Study Finds Global Cities Have Warmed Due To Rising Solar Surface Forcing Since 1986

The globe’s cities are warming primarily due to declining albedo, not CO2 radiative forcing. According to a comprehensive new study published in Remote Sensing of Environment, CO2 fertilization has led to an enhanced greening trend in 72.6% of cities across the world since 1985, accelerating to 89.2% since 2001. Per the authors, this greening trend […]

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

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 […]

New Studies: Selection Bias In Datasets Advances A False Narrative The Sun Has No Climate Impact

New Studies: Selection Bias In Datasets Advances A False Narrative The Sun Has No Climate Impact

Solar forcing may have a 4 to 7 times greater effect on climate change than current climate models indicate, which may mean modern climate change is predominantly natural rather than anthropogenic. Anthropogenic global warming (AGW) attribution may be significantly dependent on the choice of dataset. Advocates of AGW may only use Total Solar Irradiance (TSI) […]

New Study: 'Atmospheric CO2 Is Not The Cause Of Climate Change' ... The Next Glaciation Has Begun

New Study: ‘Atmospheric CO2 Is Not The Cause Of Climate Change’ … The Next Glaciation Has Begun

CO2 “only affects a small range of long-wave re-radiation from the surface of the Earth,” and there “seems to be no connection between carbon dioxide and the temperature of the Earth.” − Harris, 2023 New research published in the MDPI journal atmosphere by Dr. Stuart A. Harris asserts past and modern climate changes are natural […]

New Study: Earth Will Cool By 1°C Over The Next Decades Due To The Upcoming Grand Solar Minimum

New Study: Earth Will Cool By 1°C Over The Next Decades Due To The Upcoming Grand Solar Minimum

“The first modern GSM1 [Grand Solar Minimum] occurs in 2020 – 2053 with the cycle amplitudes reduction to 80% in cycle 25, to 30% in cycle 26 and to 70% in cycle 27 from the maximum amplitude of cycle 24.” − Zharkova et al., 2023 Per a new study, Earth’s Total Solar Irradiance (TSI) has […]

New Study: 'Natural Climate Drivers Dominate In The Current Warming'

New Study: ‘Natural Climate Drivers Dominate In The Current Warming’

More and more evidence is emerging that the modern warming trends are naturally driven, not anthropogenic. Per CERES observations the surface incident shortwave (SW) radiation anomaly increased by +1.61 W/m² from 2001 to 2019, and +1.75 W/m² from 2001 to 2021 (Ollila, 2023). This SW increase is likely due to natural variations in cloud cover […]

New Study: Up To 87% Of Modern Warming Can Be Explained By Variations In Solar Activity

New Study: Up To 87% Of Modern Warming Can Be Explained By Variations In Solar Activity

Nearly all of the alleged anthropogenic link to climate change can be removed simply by exchanging and/or replacing biased temperature and solar activity data sets. A new study authored by 37 scientists in the journal Climate finds using rural-only Northern Hemisphere temperature data (i.e., removing artificial, non-climatic urban heat effects) reduces the post-1850 warming trend […]

Solar Variability Linked To Climate Change...CO2 Not 'The Primary Driver For Nearly All Of Earth's History'

Solar Variability Linked To Climate Change…CO2 Not ‘The Primary Driver For Nearly All Of Earth’s History’

A new study exposes the uncertainty in solar activity reconstructions, but suggests solar models explain climate changes far better than atmospheric CO2 concentrations. Proxy model estimates of the impact of solar variability on climate are highly uncertain. For example, estimations of the increase in solar irradiance over the last 400 years range anywhere from 0.75 […]

New Study: Shortwave Climate Forcing Increased From 2001-2018, Explaining The Warming

New Study: Shortwave Climate Forcing Increased From 2001-2018, Explaining The Warming

Yet another observational study determines changes in Earth’s reflectiveness, or planetary albedo, may be primarily responsible for 21st century climate forcing. Earth’s radiation budget at the top of atmosphere (TOA) is predominantly controlled by internal changes in cloud cover. A declining albedo – linked to declining cloud cover – corresponds to an increase in the […]

New Study: Observational Data Affirm 95% Of Post-1970s Warming Is Not Linked To CO2 Increases

New Study: Observational Data Affirm 95% Of Post-1970s Warming Is Not Linked To CO2 Increases

Of the warming trends in Poland and greater Europe, “only about 4–5% are explained by an increase in CO2 concentration.”  –  Marsz et al., 2022  Internal changes to the thermal structure of the ocean transmit decadal-scale changes in the atmospheric circulation and consequent surface air temperature via its modulating impact on the variation in the […]

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

Scientists 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 satellite-observed decline in […]

Scientists: Enhancing Earth's Surface Reflectiveness 32x More Effective Than Eliminating GHG Emissions

Scientists: Enhancing Earth’s Surface Reflectiveness 32x More Effective Than Eliminating GHG Emissions

Adding reflectors to roofs and pavements and similar strategies could globally reflect 87 W/m² more incoming solar radiation than is reflected on an annual basis currently, cooling the surface. In contrast, the sum of the accumulated annual anthropogenic radiative forcing from greenhouse gases (GHG) since 1750 is 2.72 W/m². A new study analyzes the effectiveness […]
