Share this…FacebookTwitterA recent study appearing in Nature, “Current Atlantic Meridional Overturning Circulation weakest in last millennium“, authored by Caesar et al, hints at a global climate system on the verge of tipping out of control. According to their findings, the weakening of the so-called Atlantic Meridional Overturning Current (AMOC) in the 20th century is “unprecedented”, […]

Share this…FacebookTwitter In 2020, more than 400 scientific papers were 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 mainstream media sources. Over 400 scientific papers […]

Share this…FacebookTwitterOceans cover 71% of the Earth’s surface. An analysis of CO2’s radiative effect on ocean temperatures finds CO2 forcing is negligible even after reaching a concentration of 1,071 ppm. In the tropical oceans, 500 to 1,000 W/m² of solar radiation uniformly heats the first 2 meters of the ocean surface by 2 Kelvin in […]

Share this…FacebookTwitterDespite sea level rise, a 2019 global analysis (Duvat, 2019) found 89% of 709 island coasts have been either stable or growing in size in recent decades. A new Maldives-only study (Duvat, 2020) finds rapid (>3 to >50%) coastal growth in 110 of 186 Maldives islands from 2005 to 2016. Just 5 islands – […]

Share this…FacebookTwitterEarly in 2011, NTZ readers and I entered a climate bet with Rob Honeycutt and climate warming dogmatist Dana Nuccitelli. The bet, which I dubbed the Honeycutt Climate Bet for Charity, was whether globally the 2011-2020 decade would be warmer or cooler than the previous 2001-2010 decade. Myself and and a number of NTZ […]

Share this…FacebookTwitterThe forcing uncertainties and lack of observational measurements in the top-to-bottom global ocean preclude an assessment that modern warmth is due to anthropogenic activities. Key points from a new paper (Gebbie, 2021): • 93% of the changes to the Earth’s energy budget, manifested as warming of the Earth system, are expressed in the global […]

Share this…FacebookTwitterIt didn’t receive much a attention in 2015, but a comprehensive Nature journal study of 0-2000 A.D. global sea surface temperatures shows 1) climate changes occurred more than twice as fast during the Little Ice Age (LIA) than since 1800, 2) the entire first millennium was >1 standard deviation (s.d. unit) warmer than today, […]

According to the much ballyhooed data, temperatures in Europe in September this year were on average 0.2 degrees Celsius higher than in the previous record September 2018. The […]

Share this…FacebookTwitterToday’s global ocean temperatures hover around 15°C on average. About 400 to 500 million years ago, Earth’s ocean temperatures averaged 35-40°C and atmospheric CO2 concentrations were “5-10x higher than present day values” (Henke et al., 2018). During this period, the marine biosphere thrived (Voosen et al., 2019). Image Source: Henke et al., 2018 Image […]
