If the error and uncertainty associated with determining the extent to which natural factors (aerosol forcing, downwelling shortwave variability) affect climate are factors of ten times larger than the presumed effects of human activity, then we cannot definitively say human activity is driving climate change. It takes 10 years and 22 ppm for CO2 forcing […]

Precipitation records can be directly associated with climate changes and thus temperature changes. And for “all over the UK and Ireland” there has been no detectable rainfall patterns that could be linked to rising CO2 throughout the Industrial Era. The Rainfall Rescue project used volunteers to digitize 66,000 pages containing 5.28 million hand-written monthly rainfall […]

There are four main reasons why Antarctica’s Larsen C Ice Shelf may be melting. None of them involve human forcing or CO2 concentration changes. Scientists have recently completed an exhaustive 20-year study of the “most significant causes of melting” of the Larsen C Ice Shelf in the Antarctic Peninsula. They have concluded the 4 main […]

Alarmist climate research centers like the Potsdam Institute and the unquestioning media have been claiming for years that the Jet Stream is weakening, hence this would lead to greater weather extremes across the northern hemisphere due to blocking. Responsible for this of course is man-made global warming. Hat-tip: The Klimaschau But a recent paper by […]

Cloud modulation of shortwave radiation and greenhouse effect forcing has largely been the determining factor in the global warming of the last 45 years. Not CO2. CO2 forcing and its effect on surface temperatures is detailed in analyses of changes in clear-sky radiation only because all-sky radiation effects that include clouds (and the real-world atmosphere […]

Since 2000 there has been a natural reduction in net air-sea fluxes at the same time there has been rapid warming in the Indian Ocean. This affirms anthropogenic surface forcing cannot explain the recent warming in at least half the global ocean. The Indian Ocean covers approximately 20% of the ocean surface, but this basin […]

Of all the possible reasons for a warming Arctic since 2002, it has been determined that “the clear-sky downward long-wave radiation caused by water vapor” is the dominant cause. A new study says that when it comes to downwelling long-wave, water vapor, clouds, and temperature are the main factors determining its intensity. “As is well […]

A new study uses existing temperature and CO2 records and albedo/natural variability attribution to suggest most of the recent warming is natural. The climate sensitivity to CO2 forcing is just over 0.2°C for a 100 ppm concentration increase. Dr. Syun-Ichi Akasofu is an “expert in aurora physics, solar physics, geophysics, and magnetosphere” and the founder […]

In 2021, several hundred more scientific papers were published that cast doubt on the position that anthropogenic CO2 emissions function as the climate’s fundamental control knob…or that otherwise serve to question the efficacy of climate models or the related “consensus” positions commonly endorsed by policymakers and mainstream media sources. These scientific papers affirm the position […]

The net climate forcing from albedo changes can account for the increase in ocean heat content in recent decades. Scientists (Goode et al., 2021) have determined Earth’s albedo declined from 1998-2017, driving a +0.5 W/m² net increase in absorbed solar radiation, a positive energy imbalance. Image Source: Goode et al., 2021 The authors report it […]

A new study affirms Europe’s worst one-year droughts of the 21st century (2003, 2015, and 2018) have been far less severe than the 50+ consecutive years of “megadroughts” linked to the solar-minima-induced coldest decades of the 15th to 19th centuries. There is a clear link between cooler temperatures and aridity documented in the scientific literature […]

Dozens of rapid warming and cooling periods episodically occurred throughout the last glacial. However, they have often been dismissed as local-only events. A 2020 study published in Science robustly affirms steeper-than-today warming periods spanned both hemispheres and 23 of 25 were “globally synchronous.” Geologists have long recognized that Greenland abruptly warmed up by 5 to […]
