Share this…FacebookTwitterIn 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 […]

Share this…FacebookTwitterDuring the Early Holocene, when CO2 levels lingered near 260 ppm, ice core records suggest surface temperatures in Iceland were about 3°C warmer than today. Iceland’s extensive lakes and glaciers topography provides a verifiable history of the region’s paleoclimates. For example, scientists can infer summer temperatures 3°C warmer than today in Iceland to account […]

Share this…FacebookTwitterAt the end of the last glacial, when CO2 concentrations hovered around 250 ppm, there were abrupt warming and cooling events in the Spanish mountains (Béjar range) with magnitudes of 3°C within decades. Peak temperatures were at times warmer than today. It has often been claimed that abrupt warming and cooling events with amplitudes […]

Share this…FacebookTwitterNew paleoclimate records from Europe, Scandinavia-Russia, China, and the northeastern USA indicate there has been no unusual modern warming. Instead, these newly published reconstructions show warmer periods and more rapid centennial-scale warming events occurred in past centuries, or when CO2 concentrations were much lower than they are now. United States In the late 1990s […]

While the video’s main focus is on Germany, it presents several key points that tell us why natural factors are just as much at play, if not more. Sea surface temperature […]
