Share this…FacebookTwitterScientists (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 be elicited […]

Share this…FacebookTwitterIn the last few years, hundreds of peer-reviewed scientific papers have been published linking changes in solar activity to Earth’s climate (2016, 2017, 2018). The evidence for a robust Sun-Climate connection continues to accumulate in 2019. When it comes to the Sun’s influence on climate, one conclusion is certain: there is no widespread scientific […]

Share this…FacebookTwitterA new reconstruction of Arctic (NW Greenland) sea ice cover (Caron et al., 2019) reveals modern day sea ice is present multiple months longer than almost any time in the last 8000 years…and today’s summer sea surface temperatures s are among the coldest of the Holocene. Yet another new study (Caron et al., 2019) […]

Share this…FacebookTwitterGreta Thunberg lives in Sweden. According to peer-reviewed science, Sweden was at least 3°C warmer than it is today about 6000 to 9000 years ago, when CO2 concentrations lingered around 265 ppm. At 410 ppm CO2, 21st century Sweden is colder now than almost any time in the last 9000 years. Image Source: Grudd, […]

Share this…FacebookTwitterCO2 concentrations have risen from 310 ppm to 410 ppm since the 1930s. However, there has been no net change in Arctic or Greenland temperatures during these last 90 years. During the Pliocene, CO2 also ranged between about 300-400 ppm, but the Arctic was 15-22°C warmer and sea levels 25 meters higher than today. […]

Share this…FacebookTwitterA growing proportion of Sweden’s energy is derived from burning biomass (wood), which increases CO2 emissions 65% and 285% more than coal and natural gas energy generation, respectively. And yet because governmental policy – not science – has (wrongly) declared biomass burning “renewable” and “carbon neutral”, Greta Thunberg’s Sweden is falsely credited with reducing […]

Share this…FacebookTwitterGreenland’s ice sheet mass losses have significantly decelerated since 2013 – a reversal from the rapid retreat from the 1990s to 2012 driven by cloud forcing and the NAO (Ruan et al., 2019). The post-2013 “relatively stable” ice sheet even gained mass during 2017-’18 (Andersen et al., 2019). Ruan et al., 2019 Decelerated […]

Of the 53 total tide gauges, 45% (24) are negatively accelerating, 14 document falling sea levels, and just 11 have sea levels rising more than 3 mm/yr. Image Source: Boretti, 2019 […]

Last year, Dr. Rex J. Fleming, a former NOAA climate scientist who earned both his Master’s and Ph.D in meteorology, published a paper (Fleming, 2018) in the Environmental Earth Sciences journal […]

Share this…FacebookTwitterNASA has conceded that climate models lack the precision required to make climate projections due to the inability to accurately model clouds. Clouds have the capacity to dramatically influence climate changes in both radiative longwave (the “greenhouse effect”) and shortwave. Cloud cover domination in longwave radiation In the longwave, clouds thoroughly dwarf the CO2 […]

Share this…FacebookTwitterIn recent decades, the Earth’s seas have been rising at a rate of under 0.8 mm/year (8 cm per century) according to estimations of the sum of contributions to sea level rise. In contrast, sea levels rose at rates of more than 40 mm/year ~10,000 years ago. Relative sea level rise can be calculated […]

According to scientists (Yan et al., 2019), coral reef ecosystems thrive in centennial-scale warming phases such as the Medieval Warm Period and Current Warm Period, whereas they experience population declines (“switch-off” episodes) during […]

Share this…FacebookTwitterHigher frequencies of drought and extreme rainfall are assumed to be associated with modern climate change. But long-term studies in both hemispheres indicate extreme precipitation patterns were more common prior to the 20th and 21st centuries. Natural variability dominates precipitation patterns so thoroughly that an anthropogenic signal cannot be detected in observed records. Internal […]

According to scientists, the overwhelming majority of the “significant increases in tropical forests and the forests of North America, Eurasia, and China” since the early 1990s can be attributed to the combination of CO2 fertilization (56%) and climate change (35%).

The authors of a new study (Jiao et al., 2019) point out that temperature changes in the Tianshan mountains are “mainly influenced by the solar activity via the mean minimum temperature within approximately 11-year periods.” Despite some warming since […]
