Discovery: Past Global Warming was more Extreme, Temperatures of 12–14C, today equivalent is around 1–2C

Ars Technica: New technique shows old temperatures were much hotter than thought. Results imply Earth may be more sensitive to carbon dioxide than previously known. In a paper recently published in Science, Professor Nele Meckler of the University of Bergen and colleagues argue that the climate between around 35 and 60 million years ago may have been…

Climate tipping-point potential and paradoxical production of methane in a changing ocean

Authors: Hongyue Dang, Jia Li Dang, H. & Li, J. Sci. China Earth Sci. (2018) 61: 1714. https://doi.org/10.1007/s11430-017-9265-y Access and read the PDF with inline linkages, and reference list here. Abstract The global warming potential of methane (CH4) is about 30 times stronger than that of carbon dioxide (CO2) over a century timescale. Methane emission is hypothesized…

Cleaner Air, The Ocean, and Global Warming

Reductions in sulfur dioxide (SO2) emissions in recent years, for cleaner air, mainly in South East Asia due to a severe manufacturing sector slowdown and pollution policy changes (1,2) may attribute to current warming, since the phenomena called global dimming is involved. The first policies to address air pollution in the 20th century, originated after…

A potential future world scenario, driven by rapid regional changes

As someone who follows the climate topic for several years, I’ve to conclude that we are still far away from taking climate change seriously. Around 10 years ago there were rather minor groups of concerned scientists and bloggers, while the media was giving “a balanced view” to the so called deniersphere. This went on for…

Climate change could suffocate life on planet Earth

EurekAlert (Release): Falling oxygen levels caused by global warming could be a greater threat to the survival of life on planet Earth than flooding, according to researchers from the University of Leicester. A study led by Sergei Petrovskii, Professor in Applied Mathematics from the University of Leicester’s Department of Mathematics, has shown that an increase in…

Research links abrupt paleoclimatic change to possible methane hydrate destabilization

Using a core sample from the Santa Barbara Basin, UCSB researchers decipher the history of paleoclimate change with surprising results By Julie Cohen (UCSB): Global climate change isn’t new — the phenomenon has been around for millions of years. But now, a core from the ocean floor in the Santa Barbara Basin provides a remarkable…
