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…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…FacebookTwitterAn observational analysis of photometric evidence suggests solar forcing of Earth’s atmosphere could vary by as much as ±4.5 W/m² since 1750, which is “far larger than the IPCC estimate of −0.30 to +0.10 W/m²” (Judge et al., 2020). A 2017 study suggested the solar activity during the “modern maximum period from 1940 to […]

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…FacebookTwitterReforestation removes CO2 from the atmosphere. Reforestation substantially cools the Earth’s land surfaces. Therefore, reforestation offers a “meaningful opportunity for local climate mitigation and adaptation”. So why are we focused on CO2 mitigation via reduction in fossil fuel use? Cooling the surface via reforestation A few months ago NoTricksZone featured a new study that […]

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 […]
