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 […]

Greenland has not warmed (net) in the last 90 years. From 80,000 to 20,000 years ago Greenland warmed by 10-15 Kelvin within a span of “a few decades” 24 times (Kypke and Ditlevsen 2024). These abrupt warming periods occurred without concomitant CO2 concentration changes. And, of course, without human interference. Image Source: Kypke and Ditlevsen […]

“Modern warming is within natural Holocene climate variability” – Kullman and Öberg, 2024 From about 16,800 to 6000 years ago warmth-dependent tree species grew 300-700 altitudinal meters higher than they do today on Mt. Åreskutanthan, Swedish Scandes. Due to the well-known warmth threshold for boreal tree species and the lapse rate (0.6°C per 100 m), […]

It’s the oceans, stupid (not CO2)! The latest climate information video released by the Germany-based European Institute for Climate and Energy (EIKE) presents a recent paper by Huang et al appearing in the journal Geophysical Research Letters: “Contrasting Responses of Atlantic and Pacific Tropical Cyclone Activity to Atlantic Multidecadal Variability” The paper examines the influences […]

Yet another region of the world has failed to cooperate with then anthropogenic global warming narrative. Asad et al., 2024 “The longest 10 years’ warm periods were observed during the early decades of the twentieth century (AD 1918–1927…)…” “The five hottest years (based on 7.33 °C ± 0.99 °C) were AD 1896 (9.80 °C), 1892 […]

The radiative effect of natural wildfire aerosol forcing alone can be said to fully cancel out the total accumulated forcing from 170 years of CO2 increases in the current climate. It has been estimated that the total change in climate forcing (radiation imbalance) from the 1750 to present CO2 concentration increase has been 1.82 W/m². […]

CO2-induced global warming was supposed to intensify the hydrological cycle and extreme precipitation. It hasn’t. New research (Mitchell and Knapp, 2024) at a southeastern United States study site indicates there has been no significant trend in either total precipitation or intense rainfall events (IRE) over the last 250 years (1770-2020). However, there was more IRE […]

A -0.005°C temperature change over a span of 60 years in northern Pakistan (Himalaya region) is ostensibly having “adverse impacts in multiple sectors.” The first sentence of a new paper’s (Khan et al., 2024) abstract claims: “Hindu Kush Himalaya region is experiencing rapid climate change with adverse impacts in multiple sectors.” But in the body […]
