It 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, and […]

Our 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 service […]

Today’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 Source: […]

Today we present two papers on climate reconstruction using proxy data. One about East Antarctica and the other about belize. Hat-tip reader Mary Brown. AMO behind sea surface temperatures First we look at a paper authored by a team of German scientists: “Great Blue Hole (Lighthouse Reef, Belize): A continuous, annually-resolved record of Common Era […]

A 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 carbon […]

By 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 the […]

Extensive 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 1990s […]

Image cropped from Met Office here. By Die kalte Sonne (German text edited by P. Gosselin) On June 3, 2020, npj Climate and Atmospheric Science published a study by Athanasiadis et al. 2020, in which the authors investigated the question of whether changes in the frequency of blocked weather situations in the North Atlantic and […]

Elsevier has accepted a new paper by Lüdecke et al, 2020, showing natural oceanic and solar cycles play a large role in modulating Europe’s climate. Offers new chances for robust midterm temperature prognoses. The paper, in press, journal pre-proof, analyzes natural variability in European monthly temperatures on decadal and multidecadal timescales and their possible drivers. […]

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 warming […]

From 2008 to 2016 a widespread cooling ranging from 0.6°C to more than 2.0°C has chilled effectively the entire oceanic region from E. Canada to N. Iceland to S. Europe. 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 scientists […]

According 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? Global […]
