Share this…FacebookTwitterAccording to a new paper, the Earth’s ocean heat content time derivative (OHCTD) has been decreasing (-0.26 W/m²/decade) since 2000, coinciding with a similar deficit in the Earth’s energy imbalance (EEI). The authors acknowledge such trends are “surprising” considering greenhouse gas emissions have risen. Image Source: Dewitte et al., 2019 Earth’s energy budget imbalanced? […]

Share this…FacebookTwitterCO2 concentrations rose from 345 ppm to 398 ppm in the 29 years from 1985 to 2014. Mainstream scientists sympathetic to the anthropogenic global warming (AGW) paradigm have nonetheless reported the overall greenhouse effect forcing has been flat to declining throughout this period. 1. Cess and Udelhofen, 2003 Due to the downward trend in […]

Share this…FacebookTwitterFor CO2 to be considered a driver of Earth’s temperatures, changes in CO2 that uni-directionally correlate with temperatures should not be an exceptional occurrence. Yet a causal link from CO2 radiative forcing to temperature changes could hypothetically be inferred for just 2.6% of the last 425 million years. A detailed analysis (Davis, 2017) of […]

Share this…FacebookTwitter Within the last few years, over 50 papers have been added to our compilation of scientific studies that find the climate’s sensitivity to doubled CO2 (280 ppm to 560 ppm) ranges from <0 to 1°C. When no quantification is provided, words like “negligible” are used to describe CO2’s effect on the climate. The […]

Share this… Facebook Twitter It’s been acknowledged by mainstream scientists for years now that at certain locations on planet Earth, rising carbon dioxide levels cause cooling. It’s now been determined that rising CO2 also causes “negligible” cooling (or warming) depending on the season. A few years ago a seminal paper (Schmithüsen et al., 2015) was […]

Share this… Facebook Twitter CO2 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 […]

Share this… Facebook Twitter Two 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 […]

Share this… Facebook Twitter Two 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 […]

Share this… Facebook Twitter The 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 […]

Share this… Facebook Twitter In the first 5½ months of 2019, over 200 scientific papers have been 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 […]

Share this… Facebook Twitter According 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 […]

Share this… Facebook Twitter The 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 […]
