Marine species subjected to high CO2 extremes – 8,891 to 95,000 ppm – in their natural environments may not be adversely affected. They may even “thrive”. 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 in […]

In a new climate reconstruction for the Tibetan Plateau (Liang et al., 2020), scientists report a) the highest Holocene temperatures occurred about 8,500 to 6,000 years ago; b) “century-scale climate fluctuations” correlate “statistically and visually” with solar forcing estimates; and c) “we are in the middle of the 500-yr-long relatively warm period” and “this natural […]

Scientists 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 until […]

Glacier 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 of […]

From 1993 to 2018, the satellite altimetry sea level changes reveal both positive and negative accelerations, align with oscillatory patterns, and are dominated by internal variability (e.g., PDO, ENSO). 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 level […]

By Die kalte Sonne The past winter in central and northern Europe was quite warm. Why is that? The Norwegian Centre for Climate Research CICERO explains it in an article from 6 January 2020: Unseasonal temperatures for Norway The unusual warm temperatures this winter and forecasts indicating milder winter conditions for January, February and March […]

In 2019, more than 440 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. Image Source: Collins et al., 2019 […]

Though the media like to tell their audience that man-made climate change is leading to more extreme weather, the data don’t support it. In fact, one could easily argue that Japan’s climate is more agreeable today. By Kirye in Tokyo and Pierre Gosselin No trend in long-term annual precipitation Over the past 100 years, for […]

For 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 temperature […]

As reported in 4 separately-published papers, scientists have discovered a mechanism whereby islands can build themselves up naturally, thwarting the threat of sea level rise. Tuck et al. (2019) affirm the “implications of island building are profound, as it will offset existing scenarios of dramatic increases in island flooding.” Earlier this year, Duvat (2019) identified […]

A recent study finds that Africa’s freshwater storages are driven by natural variability. Image: ScienceDirect Hat-tip: Mary Brown The authors examined GRACE satellite data and also found that Central Africa’s water storages are partially controlled by deforestation, and in northern Africa are controlled by groundwater extraction. What follows is the paper’s abstract, which does not […]

Amazing: A proxy study of Laos finds natural variability in hydrometeorology, a little Ice Age, and other substantial climate changes in the pre-greenhouse gas era. Who would have thought! (sarcasm) Hat-tip: NTZ reader Mary Brown. University of California Irvine researcher Jessica Wang and her team of researchers find plenty of natural climate variability in Southeast […]
