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…FacebookTwitterTwo University of Turku (Finland) physicists have determined a) the climate’s sensitivity to a doubling of CO2 is 0.24°C, b) the human contribution to the warming of the past century is only about 0.01°C, c) the IPCC and climate modeling dramatically overestimate CO2’s climate impact, and d) variations in low cloud cover control the […]

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 […]

Share this…FacebookTwitterAccording to the calculations of Dr. James Hansen, the radiative influence derived from the increase in CO2 during the last deglaciation was so negligible that it equated to “a third of energy required to power a honey bee in flight” (Ellis and Palmer, 2016). Image Source: Ellis and Palmer, 2016 Between about 22,000 and […]

Share this…FacebookTwitterThe Greenhouse Effect On Hiatus An unheralded but significant 2016 scientific paper – “A Hiatus in the Greenhouse Effect” – is now publicly available. It had previously been paywalled. Scientists have found the greenhouse effect’s (GHE) influence on planetary temperatures went on “hiatus” during 1992-2014. The estimated GHE radiative influence for these 22 years […]

Share this…FacebookTwitterThere are large regions of the globe where observations indicate there has been no warming (even cooling) during the last decades to century. 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 […]

Share this…FacebookTwitterClimate models postulate that increasing CO2 concentrations will intensify the Earth’s water cycle. This intensification is believed to eventually result in dangerous (3°C and up) global warming. Observational evidence has thus far falsified these IPCC-endorsed claims.

Share this… Facebook Twitter In two new papers, scientists affirm a strong connection between solar activity and the Earth’s climate, as temperatures are said to be 3 times more sensitive to solar forcing than CO2 forcing.

New calculations reveal that the climate’s sensitivity to a […]

Share this… Facebook Twitter The abysmal track record of computer models in simulating climate trends has increasingly been highlighted in the scientific literature. Recently published papers indicate that in some cases climate models actually get it right zero percent of the time (Luo et al., 2018; Hanna et al., 2018), or that hydrological models are off […]
