A professor of hydrology from the University of Athens eviscerates the “naïve” paradigm that says the natural state of Earth’s climate is constancy and stability, only changing when an “external agent” (i.e., a rapid increase in fossil fuel emissions ) acts upon it. Instead, (a) water is the main element driving climate and (b) the […]

A new study asserts that when Greenland naturally warms by multiple degrees per decade, this “abrupt climate variability can result entirely from unforced or noise-induced oscillations of the coupled atmosphere-ice-ocean system.” This means the recent modest climate changes for Greenland may easily fall within the scope of an unforced natural variability pattern. In the last […]

Africa climate variability linked to natural oceanic and solar cycles, a new study affirms. No mention of CO2. Image source: “Decadal and multidecadal natural variability of African rainfall“. A new study analyzes patterns of natural rainfall variability and can provide crucial assistance to African countries in seasonal rainfall forecasting for agriculture and protection against droughts […]

An assessment of the 1856-2012 drought frequency/intensity along the US West Coast leaves no role for human activity in hydroclimate. Across the globe, no clear precipitation trends have been observed in the last several decades (Nguyen et al., 2018) Image Source: Nguyen et al., 2018 Instead of an intensification of the hydrological cycle projected by […]

In 2020, more than 400 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. Over 400 scientific papers published in […]

Scientists are increasingly finding that abrupt, decadal-scale temperature changes of multiple degrees Celsius can arise unforced and spontaneously. The surface temperatures for the Greenland ice sheet have been known to warm 8 to 16°C “within decades or less” – yes, fewer than 10 years – due to “unforced oscillations.” In other words, no external forcing […]

The forcing uncertainties and lack of observational measurements in the top-to-bottom global ocean preclude an assessment that modern warmth is due to anthropogenic activities. Key points from a new paper (Gebbie, 2021): • 93% of the changes to the Earth’s energy budget, manifested as warming of the Earth system, are expressed in the global ocean. […]

A new assumption about carbon budgets reveals climate scientists have been vastly underestimating (by a factor of 2) the amount of carbon absorbed by the ocean for decades. Every past carbon budget estimate has been twice as wrong as the current estimate. When it comes to the ocean heat fluxes and source vs. sink carbon […]

A new paper reveals that climate models have failed to take important natural factors, such as the North Atlantic Oscillation, into account in their climate models on which leaders have been basing their policies. A new paper in Nature says NAO not taken adequately into account by climate models. Image: see video (German) here. Paper […]

Günther Aigner released a German video with the title “Die Alpengletscher im Klimawandel: Status quo“ (The Alps glaciers in climate change: status quo). Hat-tip: Die kalte Sonne Today global warming alarmists insist blaming climate change on man-made CO2 emissions. Yet, everywhere we look it’s difficult to find any correlation between CO2 and warming. Pre-industrial history […]

It is claimed Earth’s surface has warmed by 1°C in the last 140 years – which is a supposedly rapid climate change. But a new study suggests the Northern Hemisphere surface naturally cooled by 1°C in 8 or 9 years, then warmed up again by 1°C within decades during the Late Antique Little Ice Age. […]

A new study documents the dominance of internal variability in decadal-scale global temperature changes and suggests we may experience a global cooling trend during the next 15 or even 30 years despite rising greenhouse gases. Maher et al. (2020) acknowledge that internal variability in global surface temperature variations is “a difficult concept to communicate” because […]
