Share this… Facebook TwitterCorals thrive in multiple-degrees-warmer-than-today waters and their growth is stunted in cooler environments. The warnings peddled by climate alarmists often characterize Earth’s 500 billion corals as critically endangered by modern global warming. But the science itself says corals have been and continue thriving in the Current Warm Period – just as they […]

Share this… Facebook TwitterA new analysis has Poland’s July temperatures hitting 20.6°C in Medieval times, whereas they’re only 17.4°C today. The temperature record for this region also shows today’s temperatures are not much different than they were during the Little Ice Age. Another chart contained in the study (Pleskot et al., 2022) shows North America’s […]

Share this… Facebook TwitterThe cryosphere is failing to cooperate with the anthropogenic global warming narrative that says rising greenhouse gas emissions should be catastrophically melting Arctic ice. Scientists (O’Regan et al., 2021) report Ryder Glacier in north Greenland has advanced 2,881 m from 1948-2015 given its advancing rate of 43 m/yr-1. Its modern ice extent […]

Share this… Facebook TwitterThe IPCC’s latest report uses a hockey stick-shaped reconstruction of global temperatures that wholly contradicts previous records produced by the same PAGES 2k and Oceans 2k consortiums from 4 years earlier. In 2015, the PAGES 2k Consortium published an updated (“corrected”) 0-2000 AD global reconstruction that showed a large portion of the […]

Share this… Facebook TwitterChina’s climate history includes multiple climate warming and cooling fluctuations of 4°C within centuries, with cold periods aligning with declines in solar irradiance. According to a new study (Zhang et al., 2021), northern China’s coldest temperatures of the last 5000 years occurred 300 calibrated years before present (cal yr BP), coinciding with […]

Share this… Facebook TwitterReconstructions of past temperatures show much colder periods with higher CO2 levels or as-warm or warmer periods with much lower CO2 levels. A new study (Paus, 2020) indicates modern July temperatures center around 7.5 to 8°C in the Scandes Mountains (Norway). Today’s CO2 atmospheric concentration has reached 410 ppm. During the latter […]

Share this… Facebook TwitterIt didn’t receive much a attention in 2015, but a comprehensive Nature journal study of 0-2000 A.D. global sea surface temperatures shows 1) climate changes occurred more than twice as fast during the Little Ice Age (LIA) than since 1800, 2) the entire first millennium was >1 standard deviation (s.d. unit) warmer […]

Share this… Facebook TwitterCoastal history analyses increasingly suggest sea levels are lower today than at any time in the last 7000 years – even lower than the 1600s to 1800s. Recently we compared cartology from the 17th to 19th centuries to direct aerial images of coastal positions today. Rather surprisingly, there seemed to be more […]

Share this… Facebook TwitterScientists (Bragato and Holzhauser, 2019) find natural catastrophes like tornadoes and earthquakes and pandemics like plague, cholera, and influenza “concentrate in the periods of ice expansion in Europe” whereas periods of economic expansion and a lower incidence of natural catastrophes and pandemics occur during deglaciation phases, or warm periods. Century-scale cooling can […]

Share this… Facebook TwitterAmazing: 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 […]

Share this… Facebook TwitterNewly published macrofossil discoveries from 4 papers strongly suggest that modern warmth may still be about 3°C colder than nearly all of the last 10,000 years. Image Source: Leunda et al. (2018) 1. Permafrost is still present today in a region that was permafrost-free throughout the Holocene (until the onset of the Little […]

Share this… Facebook TwitterEven though CO2 concentrations hovered well below 300 ppm throughout most of the Holocene, newly published paleoclimate reconstructions affirm that today’s surface temperatures are only slightly warmer (if at all) than the coldest periods of the last 10,000 years. This contradicts the perspective that temperatures rise in concert with CO2 concentrations. Bottom Graph […]
