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…FacebookTwitterBoth during the last interglacial (~120,000 years ago) and from roughly 2000 to 7000 years ago, relative sea levels were from 6-10 meters to 1-3 meters higher than they are today, respectively. For a list of over 100 other scientific papers indicating sea levels across the world were multiple meters higher when Earth’s CO2 […]

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 […]

Share this…FacebookTwitterGeologist Dr. Sebastian Lüning just released a video that challenges the claim that today’s warming is unusual and caused mostly by human activities. 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 […]

Share this…FacebookTwitterTwo new papers use tree ring proxy evidence to suggest modern European temperatures are neither unusual nor higher than they were during the Medieval Warm Period. Image Source: Esper et al. (2020) Esper et al. (2020) have produced a new temperature reconstruction for Southern Europe to complement past reconstructions for Northern and Central Europe. […]

Share this…FacebookTwitterSeveral new studies use evidence from temperature-sensitive plant species and megafauna remains to reconstruct an Arctic climate that was 6°C to 22°C warmer than today when CO2 concentrations lingered near 300 ppm. Navigating the Arctic Ocean William Barentsz discovered Arctic Svalbard as he sailed through an open-water Arctic Ocean using a wooden boat in […]

Share this…FacebookTwitterA new 5680-year tree-ring temperature reconstruction for southern South America (Lara et al., 2020) reveals (a) no clear warming trend in recent decades, and (b) the 18th and 19th centuries (and many centennial-scale periods from the last 5680 years) had much warmer temperatures than today.

Share this…FacebookTwitterIn 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.

Share this…FacebookTwitterA new reconstruction (Martin et al., 2020) shows peak mean annual temperatures (14°C) were 7°C warmer than today (7°C, 2009-2017) ~7800 years ago in France. In the last 200 years temperatures have fallen by ~3°C. Image Source: Martin et al., 2020 Another new study (Caillouet et al., 2019) finds little to no signficant climate […]

Share this…FacebookTwitterThe onslaught of paleoclimate evidence for warmer-than-now Mid-Holocene climates – when the Earth’s sea levels were meters higher than they are today – stormed through 2019. There were 107 scientific papers published this past year indicating today’s warmth isn’t even close to being unusual or unprecedented when compared to the climates of the last […]
