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…FacebookTwitterTwo more additions to the steadily accumulating evidence CO2 plays an insignificant to negligible role in climate change have recently been published in the scientific literature. 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…FacebookTwitterThe CO2 greenhouse effect presumably perturbs the Earth’s energy budget by driving trends in downwelling longwave radiation from the top of the atmosphere, which in turn drives changes in surface temperatures. Two scientists (Zeppetello and Battisti, 2019) have observed the opposite: perturbations in surface temperatures are what drive changes in downwelling longwave. Consequently, they […]

Climate models rooted in the assumption that fossil fuel emissions drive dangerous warming dismiss these modeling failures and project temperature increases of 3° – 10°C by 2100 for these same regions […]
