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…FacebookTwitterIn the last 35 months, 350 peer-reviewed scientific papers have been published containing documented evidence that undermines the popularized conception of a slowly-cooling Earth followed by a dramatic hockey-stick-shaped recent uptick, or an especially unusual global-scale warming during modern times. During 2017 and 2018, there were over 250 papers published in scientific journals documenting the […]

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…FacebookTwitterToday, 30% of the globe’s CO2 emissions come from China. In 10 years, China’s emissions alone will match the rest of world’s emissions combined. China continues to build hundreds of coal plants today. So why are the rest of us spending $600 billion every year on CO2 emissions mitigation? China overtook the United States […]

Share this…FacebookTwitterFour reconstructions from the central and western High Arctic reveal July temperatures were about 1-2°C warmer than today during most of the 1st millennium and Medieval period (Tamo and Gajewski, 2019). A few years ago, a chironomid reconstruction of Boothia Peninsula in the Canadian Arctic (Fortin and Gajewski, 2016) revealed not only were today’s […]

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 Scientists find three Arctic (Svalbard) lakes were all ~7°C warmer than they are now about 10,000 years ago – when CO2 concentrations were only 260 ppm. According to a just-published Geophysical Research Letters paper (van der Bilt et al., 2019), not only were surface temperatures 7°C warmer than today in High […]

Share this… Facebook Twitter Surprisingly accurate nautical maps created the 17th to 19th centuries strongly suggest coastal land area in both hemispheres were quite similar to today’s. There is even evidence relative sea levels were higher than now back then. Image Source: Etsy.com Globally, coasts have grown since the 1980s Between 1985 and 2015, satellite […]

But Mars has surface temperatures that are about -75°C colder on average than Earth’s because atmospheric density, or pressure, is the “game changer” largely determining planetary temperatures.

Share this… Facebook Twitter The Arctic’s western Barents Sea (Storfjordrenna) surface temperatures now range between 2-4°C. Sea ice persists in the region for 10 months of the year. A new study finds this same region was sea ice-free, 10°C warmer than today (13°C), and SSTs rapidly rose and fell by degrees C per century during […]

Share this… Facebook Twitter Observational uncertainty, errors, biases, and estimation discrepancies in longwave radiation may be 100 times larger than the entire accumulated influence of CO2 increases over 10 years. This effectively rules out clear detection of a potential human influence on climate. The anthropogenic global warming (AGW) hypothesis rides on the fundamental assumption that […]
