Evidence of Human-Caused Climate Crisis Has Now Reached ‘Gold Standard’-Level Certainty, Scientists Say

This article was originally published by Futurism. Read the original article. New analysis of 40 years’ worth of satellite data shows that it’s a near-certainty that humanity is actively causing global climate change. Climate deniers often claim, in the face of overwhelming evidence, that the planet is heating up and natural disasters are becoming more intense and common just because that’s the way it is …

We’re committing ourselves to many thousands of years of a warmer world if we don’t take action quickly. We’re pumping carbon dioxide into the atmosphere at a rate nine to 10 times higher than the GHG emitted during the Paleocene-Eocene Thermal Maximum (PETM), 56 million years ago

Total human carbon dioxide emissions could match those of Earth’s last major greenhouse warming event in fewer than five generations, new research finds. A new study finds humans are pumping carbon dioxide into the atmosphere at a rate nine to 10 times higher than the greenhouse gas was emitted during the Paleocene-Eocene Thermal Maximum (PETM), a global warming event that …

Doubling of Arctic methane with earlier spring rains from warming in the Arctic

Arctic Bogs Hold Another Global Warming Risk That Could Spiral Out of Control: As warming brings earlier spring rains in the Arctic, more permafrost thaws, releasing more methane in a difficult-to-stop feedback loop, research shows. By Phil McKenna Inside Climate News, FEB 19, 2019 The study appears in the journal Geophysical Research Letters. A doubling of the rate of methane released in the Arctic …

2019 climate science links

Jeff Tollefson’s 2018 piece in Nature, “Can the World Kick its Fossil-Fuel Addiction Fast Enough?” Maybe. “The good news is that clean-energy technology is at last making substantial strides. The bad news is that the pace isn’t nearly quick enough.” For a fun-to-read, technologically-informed, and cheerful view, see Angus Hervey’s four-part 2018-19 “deep dive” into the energy riddle in Future Crunch, “Homo …

January 2019 climate research

WRI, Jan 2019 Every month, climate scientists make new discoveries that advance our understanding of climate change’s causes and impacts. The research gives a clearer picture of the threats we already face and explores what’s to come if we don’t reduce emissions at a quicker pace. Our blog series, This Month in Climate Science, offers a snapshot of the month’s significant …

Climate thresholds closer than we think: oil-moisture variability notably reduces the present land carbon sink, and their results show that both variability and drying trends reduce it in the future

Soil-moisture variability notably reduces the present land carbon sink, and their results show that both variability and drying trends reduce it in the future Julia K. Green, Sonia I.
