Share this…FacebookTwitterIt 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 […]

Share this…FacebookTwitter 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 […]

Earlier this year we highlighted a study that says coral reefs “thrive” near seafloor volcanic vents where CO2 concentrations reach 60,000 to 95,000 ppm. Image Source: PHYS.ORG Urchins basking […]

Share this…FacebookTwitterScientists suggest relative sea level changes are well-correlated with natural variability and accelerated sea level rise is a “recurring feature” of what has been observed for over 300 years. Five of six studied regions along the North American Atlantic coast show declining sea level rates (mm/yr) in recent decades. After retreating into the sea […]

Share this…FacebookTwitterGlacier surges of 100s of meters within mere months have been occurring throughout High Mountain Asia (the Karakoram region, especially) for decades, even centuries. It’s the Karakoram “anomaly”, and it’s thought to be “natural”. So why are the regions where glaciers are retreating thought to be responding to unnatural climate changes? The advancing glaciers […]

The “forced acceleration pattern” assumed to be associated with anthropogenic global warming “has not emerged”. Image Source: Hamlington et al., 2020 Negative or negligible sea […]

Share this…FacebookTwitterFor CO2 to be considered a driver of Earth’s temperatures, changes in CO2 that uni-directionally correlate with temperatures should not be an exceptional occurrence. Yet a causal link from CO2 radiative forcing to temperature changes could hypothetically be inferred for just 2.6% of the last 425 million years. A detailed analysis (Davis, 2017) of […]
