Share this…FacebookTwitterA new in-press journal pre-proof paper by Hallmann et al examines reef response to sea-level and environmental changes in the Central South Pacific over the past 6000 years. Hat-tip: Reader Mary Brown The paper documents that sea levels globally saw a single short-lived sea-level highstand between 4100 and 3400 yr before present and coral reefs […]

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, […]

Share this…FacebookTwitterOur friend “SnowFan” here looks at the claims that September 2020 was the warmest ever recorded. It turns out that other measurement advanced satellites don’t agree. 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 […]

Share this…FacebookTwitterA new assumption about carbon budgets reveals climate scientists have been vastly underestimating (by a factor of 2) the amount of carbon absorbed by the ocean for decades. Every past carbon budget estimate has been twice as wrong as the current estimate. When it comes to the ocean heat fluxes and source vs. sink […]

Share this…FacebookTwitterBy Die kalte Sonne (German text translated by P. Gosselin) The Federal Ministry of Transport is looking at the temperature of the North German seas. Is that really the right Ministry for this? And why has the Green Party’s Steffi Lemke put forth this question? Before we take a closer look, let’s first clarify […]

Share this…FacebookTwitterExtensive hake (fish) skeletal remains in ocean waters too cold for this species to occupy today suggest past ocean temperatures were several degrees warmer. Fish habitats are limited by specific temperature boundaries. In a new study, for example, Wheeland and Morgan (2020) found there was a pronounced ocean warming from the 1980s to late […]

Share this…FacebookTwitter The radiative impact of CO2 on the ocean’s thermal skin layer cannot penetrate deeper than 0.01 mm. This effectively eliminates the potential for CO2 to be a driver of global warming. According to mainstream anthropogenic global warming (AGW) science, 93% of global warming is manifested in the 0-2000 m oceans. Just 1% of global […]

The cooling persists year-round and extends from the surface down to depths of 800 m. Image Source: Bryden et al., 2020 A year ago […]
