Share this… Facebook TwitterCO2 “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 […]

Share this… Facebook TwitterMore 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 […]

Share this… Facebook TwitterNearly 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 […]

Share this… Facebook TwitterA 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 […]

Share this… Facebook TwitterYet 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 […]

Share this… Facebook TwitterOf 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 […]

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 […]

Share this… Facebook TwitterAdding 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 […]

Share this… Facebook TwitterFrom 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 […]

Share this… Facebook TwitterThere has been a “strong upward trend” in solar radiation over the European continent since the 1980s driven by natural ocean circulation factors responsible for “triggering and controlling the entire chain of events in climate processes.” A new study references Dr. Michael Mann’s claim that “changes in SST and heat resources in […]
