The Tyndall Centre for Climate Change Research notes that there are no signs of a decrease in global CO2 emissions. Tyndall Centre: Global carbon emissions in 2022 remain at record levels – with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team.…
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…
Nature (February 2022): “Methane levels are growing dangerously fast,” says Euan Nisbet, an Earth scientist at Royal Holloway, University of London, in Egham, UK. The emissions, which seem to have accelerated in the past few years, are a major threat to the world’s goal of limiting global warming to 1.5–2 °C over pre-industrial temperatures, he…
Climate impacts on global agriculture emerge earlier in new generation of climate and crop models: Potential climate-related impacts on future crop yield are a major societal concern. Here we report new twenty-first-century projections using ensembles of latest-generation crop and climate models. Results suggest markedly more pessimistic yield responses for maize, soybean and rice compared to…
The study “Increasing heat and rainfall extremes now far outside the historical climate” found that the climate warmed 0.25C during the last decade, resulting in increased rainfall and heat extremes. Abstract Over the last decade, the world warmed by 0.25 °C, in-line with the roughly linear trend since the 1970s. Here we present updated analyses showing…
Twenty three reports from various agencies offer candid descriptions of how climate change is already affecting the federal government’s work and the various threats the U.S. is facing. Impacts include increases in floods and droughts, more pests and disease affecting America’s food supply, while affordable housing is increasingly at risk from both extreme weather events…
These results indicate that climate tipping is an imminent risk in the Earth System. Even the safe operating space of 1.5 or 2.0 degrees above present generally assumed by the IPCC might not be all that safe. According to the precautionary principle, we must consider abrupt and irreversible changes to the climate system as a real risk – at least until we understand these phenomena better.
Climate scientist Stefan Rahmstorf speaks on climate tipping points.
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…
