Natural atmospheric circulation patterns (like the Western Tibetan Vortex, or WTV) drive total cloud cover (TCC) change, which, in turn modulate the the amount of downward solar radiation reaching the surface. Over southwest Asia, or the Tibetan Plateau, scientists (Wang et al., 2026) indicate the satellite-observed increase in downward shortwave (DSW) “is the primary driver” […]

“The results indicate that extremes in heat-related metrics for daily T [Max] in the summer have not increased and in fact often show modest declines since 1899, due mostly to the early heat events during 1925-1954.” – Christy, 2026 The contiguous United States (CONUS) has the most reliable and comprehensive long-term daily maximum and minimum […]

“The trend of September Arctic sea ice extent for the most recent two decades 2005-2024 is -0.35 and -0.29 million km² per decade according to the NSIDC and OSISAF sea ice indices respectively…these trends are not statistically significant from zero at a 95% confidence level.” − England et al., 2025 Despite several peer-reviewed, “overly alarmist” […]

There is nothing unprecedented or even significant about modern warming magnitudes or rates. Antarctic ice cores are routinely used to represent not only global-scale CO2 records, but global temperature records over the last 800,000 years. Interestingly, if we compare modern Antarctica to paleo Antarctica we learn “no continent-scale warming of Antarctic temperature is evident in the […]

Climate changes fostered by “unforced natural climate variability” may be more than an order of magnitude larger than the climate changes commonly attributed to anthropogenic forcing. In a new study, scientists have attempted to identify the mechanisms explaining Greenland’s many historical (~80,000-11,700 years ago) climate changes that amounted to 10-15°C “in a decade or two.” […]

“[T]he fraction of [fossil] fuel-related emissions still remaining in the air (about 23 ppm out of 425 ppm at the end of 2024) cannot have any climatic effect.” – Veyres et al., 2025 A few years ago Dr. Koutsoyiannis and colleagues used equations associated with the chemistry of temperature-driven organic respiration to demonstrate that, since […]

In his latest newsletter, German professor Fritz Vahrenholt reports how the global average temperature has decreased in June and early July 2025, and has seen a downward trend since January 2025. The deviation from the long-term average of satellite measurements is +0.48 degrees Celsius, with values continuing to drop in July. Despite this global development, […]

Even if the entirety of the modern CO2 concentration increase is due to human activity, the impact (pressure) on global temperatures amounts to no more than 15-18%. In a new study, geology professor Dr. Wojciech Stankowski has summarized some of the reasons why the prevailing narrative that says humans can drive climate change by burning […]

“Since the late 1970s, Antarctic sea ice area (SIA) has slowly increased, despite significant global warming. The increase in Antarctic SIA occurred largely between 2000 and 2014.” – Bonan et al., 2024 Scientists attribute the long-term (1979-2022) expanding Antarctic sea ice trend, as well as the abrupt decline in sea ice extent from 2016 to […]

The radiation budget changes shaping trends in global dimming (cooling) and global brightening (warming) are driven by cloud cover changes, which are themselves modulated by internal deep ocean processes. A new study assesses the associated factors in North Atlantic climate variations, noting how critical clouds are in modulating Earth’s Energy Imbalance (EEI). “Cloudiness is the […]

Per a new study, the last 200 years of global warming are associated with cloud cover decline, and this decreasing cloud albedo can be linked to “the dominant roles of external forces – volcanic, solar, and oceanic – in their mutual influence after the LIA [Little Ice Age].” Scientists have repeatedly reported a satellite-observed (CERES) […]

“The main factor governing the annual increase in atmospheric CO2 concentration is the SST [sea surface temperature] rather than human emissions.” – Ato, 2024 Another day, another new scientific paper has been published reporting efforts to curb anthropogenic CO2 emissions are “meaningless.” In this study multiple linear regression analysis was performed comparing SST versus anthropogenic […]
