Share this…FacebookTwitterA long-term (50 years) study of a Great Barrier Reef (GBR) ecoystem finds corals may quickly recover from El Niño disturbances. According to scientists (Yan et al., 2019), coral reef ecosystems thrive in centennial-scale warming phases such as the Medieval Warm Period and Current Warm Period, whereas they experience population declines (“switch-off” episodes) during […]

Share this…FacebookTwitterHigher frequencies of drought and extreme rainfall are assumed to be associated with modern climate change. But long-term studies in both hemispheres indicate extreme precipitation patterns were more common prior to the 20th and 21st centuries. Natural variability dominates precipitation patterns so thoroughly that an anthropogenic signal cannot be detected in observed records. Internal […]

Share this…FacebookTwitterSatellite observations indicate the Earth has become much greener in recent decades. According to scientists, the overwhelming majority of the “significant increases in tropical forests and the forests of North America, Eurasia, and China” since the early 1990s can be attributed to the combination of CO2 fertilization (56%) and climate change (35%).

Share this…FacebookTwitterYet another region of the globe has not warmed (net) for the last 333 years. The authors of a new study (Jiao et al., 2019) point out that temperature changes in the Tianshan mountains are “mainly influenced by the solar activity via the mean minimum temperature within approximately 11-year periods.” Despite some warming since […]

Image Source: Mikkelson et al., 2018 A new paper (Axford et al., 2019) reveals NW Greenland’s “outlet glaciers were smaller than today from ~9.4 to 0.2 ka BP” (9,400 to 200 years before 1950), and that “most of […]

Share this…FacebookTwitterThe world was much warmer and greener with meters-higher sea levels just a few thousand years ago. Between 9000 to 6000 years ago, when global temperatures were 4-6°C warmer than they are today, the Sahara was a tree- and lake-covered haven teeming with megafauna and human civilizations (Manning and Timpson, 2014).

Share this…FacebookTwitterClaims that modern temperatures are globally warmer than they were during Medieval times (~800 to 1250 A.D.) have been contradicted by a flurry of new (2019) scientific papers. Southern Ocean/SE Pacific (SSTs) The Medieval Warm Period (1100 years BP) was 1.5°C warmer than today (14°C vs. 12.5°C) in the SE Pacific or Southern Ocean. […]

Share this…FacebookTwitter Image Source: National Academy of Sciences, Understanding Climatic Change About 45 years ago, the “consensus” in climate science (as summarized by Williamson, 1975) was quite different than today’s version. 1. The Medieval Warm Period was about 1°C warmer than present overall while the “largely ice-free” Arctic was 4°C warmer, allowing the Vikings to […]

Share this…FacebookTwitterA few decades ago it was “consensus” science that CO2 levels had reached 400 ppm (and even up to 500 ppm) during the Early Holocene, with rising amplitudes of greater than 200 ppm and rates of 65 ppm in less than a century. Then the “consensus” opinion changed. In 1982 it was still quite […]

Share this…FacebookTwitterScientists have found sea levels on India’s eastern coast were still 1-1.5 m higher than today as recently as 500 to 300 years ago and 3-4 m higher than today between 6000 to 4000 years ago. Seas rose and fell by multiple meters (-5 m to +3 m) within 1250 years until as recently […]

Rising CO2 leads to Antarctic cooling.

Share this…FacebookTwitterA new paper finds the performance of test-taking (cognitive, decision-making) “astronaut-like” subjects exposed to 5000 ppm CO2 was “similar to or exceeded” the performance of those exposed to baseline (600 ppm). This study follows up on a 2018 paper that determined submariners exposed to 15000 ppm CO2 performed just as well as subjects exposed […]

Share this…FacebookTwitterGeothermal heat flux can foment upper mantle temperature anomalies of 800–1000 °C, and these extreme heat intensities have been found to stretch across 500 km of central-east Greenland. This could result in “a significant contribution of ice melt to the ice-drainage system of Greenland” (Artemieva et al., 2019). Evidence of more than 100,000 formerly or […]

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…FacebookTwitterIn the coral habitats of the Western Indian Ocean, SSTs have cooled by -0.8°C since the 1980s (Watanabe et al., 2019). It has long been established that exposure to extremely low temperatures induce coral bleaching and high mortality rates just as much as warm SSTs do. Further, colder periods – which are associated with […]
