Our environment involves many different systems, and some of them are close to changing in drastic ways, for human time scales irreversible. Exceeding 1.5°C global warming could trigger multiple climate tipping points Science (Study): Climate tipping points are conditions beyond which changes in a part of the climate system become self-perpetuating. These changes may lead…
A new study concludes that our planet is dimming, a response likely due to rising temperatures. Warmer oceans seem to be generating fewer bright clouds, in turn less sunlight is reflected back into space – a feedback. Measurements of data spanning two decades, of the reflectance or albedo of Earth based on the earthshine that illuminates the Moon…
The study, “Interacting tipping elements increase risk of climate domino effects under global warming” by Nico Wunderling, Jonathan F. Donges, Jürgen Kurths, and Ricarda Winkelmann from the Potsdam Institute finds potential severe consequences from continued climate change. The Guardian has a study breakdown, which can be accessed here. Analysis shows significant risk of cascading events even at 2C…
A joint research team from Brazil and France, spearheaded by professor Marcelo Ketzer and his colleagues from the Linnaeus University uncovered methane gas leakage from gas hydrate dissociation in the Southern Hemisphere for the first time. The study authors suggest that the leakage is tied to climate change, more specifically to ocean warming. Along the…
Flood basalts and mass extinctions – ancient hyperthermals as analogs for anthropogenic climate change. Oceanic Anoxic Event (OAE) and mass extinctions are considered to be hyperthermals – usually associated with flood basalt eruptions.[2] Phases of rapid global warming, known collectively as hyperthermals.[1] Flood basalts are a subset of large igneous provinces (LIPs), the terms flood basalt…
Soil layers of permafrost that scientists expected to remain frozen for at least 70 more years have already begun thawing. NOTES In the Canadian Arctic, layers of permafrost that scientists expected to remain frozen for at least 70 years have already begun thawing. The once-frozen surface is now sinking and dotted with melt ponds and…
Thom Hartmann interviewed climate scientist Michael Mann in July 2019, here is a summary of it with a scope on our emissions, sea level rise, and what happens in the Arctic. SPEAKER Michael E.

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…
