Amazon rainforest at a critical threshold: Loss of forest worsens climate change

  2024-02-14 in Phys.org - News and Articles on Science and Technology

The Amazon rainforest could approach a tipping point, which could lead to a large-scale collapse with serious implications for the global climate system. A new Nature study by an international research team including scientists from the Potsdam Institute for Climate Impact research (PIK) reveals that up to 47% of the Amazonian forest is threatened and identifies climatic and land-use thresholds that should not be breached to keep the Amazon resilient.

A few weeks ago, a study by Copenhagen University researchers Peter and Susanne Ditlevsen concluded that the Atlantic Meridional Overturning Circulation (AMOC) is likely to pass a tipping point already this century, most probably around mid-century. Given the catastrophic consequences of an AMOC breakdown, the study made quite a few headlines but also met some skepticism. Now that the dust has settled, here some thoughts on the criticisms that have been raised about this study. ...

An earth system model shows self-sustained thawing of permafrost even if all man-made GHG emissions stop in 2020 - Scientific Reports

The risk of points-of-no-return, which, once surpassed lock the world into new dynamics, have been discussed for decades. Recently, there have been warnings that some of these tipping points are coming closer and are too dangerous to be disregarded. In this paper we report that in the ESCIMO climate model the world is already past a point-of-no-return for global warming. In ESCIMO we observe self-sustained thawing of the permafrost for hundreds of years, even if global society stops all emissions of man-made GHGs immediately. We encourage other model builders to explore our discovery in their (bigger) models, and report on their...

This tipping risk increases even if in the longer term the global temperature would stabilize within the Paris range. Avoiding an overshoot would hence limit the risks, the researchers conclude.

Tipping elements in the Earth's climate system

  2021-12-12 (or before) in PNAS - Proceedings of the National Academy of Science

The term “tipping point” commonly refers to a critical threshold at which a tiny perturbation can qualitatively alter the state or development of a system. Here we introduce the term “tipping element” to describe large-scale components of the Earth system that may pass a tipping point. We critically evaluate potential policy-relevant tipping elements in the climate system under anthropogenic forcing, drawing on the pertinent literature and a recent international workshop to compile a short list, and we assess where their tipping points lie. An expert elicitation is used to help rank their sensitivity to g...

Economists' erroneous estimates of damages from climate change

  2021-08-22 (or before) in arXiv.org e-Print archive

Economists have predicted that damages from global warming will be as low as 2.1% of global economic production for a 3$^\circ$C rise in global average surface temperature, and 7.9% for a 6$^\circ$C rise. Such relatively trivial estimates of economic damages -- when these economists otherwise assume that human economic productivity will be an order of magnitude higher than today -- contrast strongly with predictions made by scientists of significantly reduced human habitability from climate change. Nonetheless, the coupled economic and climate models used to make such predictions have been influential in the international climat...

New Research Explores the Costs of Climate Tipping Points, and How They Could Compound One Another - Inside Climate News

Calculating the future cost of global warming is one of society’s most urgent challenges. And that math will depend on the speed of major shifts in Earth’s climate system, like the complete loss of summer Arctic sea ice or the disintegration of the West Antarctic Ice Sheet, which could raise sea level much faster and […]

On avoiding dangerous anthropogenic interference with the climate system: Formidable challenges ahead

  2021-07-04 (or before) in PNAS - Proceedings of the National Academy of Science

The observed increase in the concentration of greenhouse gases (GHGs) since the preindustrial era has most likely committed the world to a warming of 2.4°C (1.4°C to 4.3°C) above the preindustrial surface temperatures. The committed warming is inferred from the most recent Intergovernmental Panel on Climate Change (IPCC) estimates of the greenhouse forcing and climate sensitivity. The estimated warming of 2.4°C is the equilibrium warming above preindustrial temperatures that the world will observe even if GHG concentrations are held fixed at their 2005 concentration levels but without any other anthropogenic forc...

Interacting tipping elements increase risk of climate domino effects under global warming

  2021-06-04 (or before) in ESD

<p><strong class="journal-contentHeaderColor">Abstract.</strong> With progressing global warming, there is an increased risk that one or several tipping elements in the climate system might cross a critical threshold, resulting in severe consequences for the global climate, ecosystems and human societies. While the underlying processes are fairly well-understood, it is unclear how their interactions might impact the overall stability of the Earth's climate system. As of yet, this cannot be fully analysed with state-of-the-art Earth system models due to computational constraints as well as some missing and uncer...

Social tipping dynamics for stabilizing Earth’s climate by 2050

  2020-01-22 (or before) in PNAS - Proceedings of the National Academy of Science

Achieving a rapid global decarbonization to stabilize the climate critically depends on activating contagious and fast-spreading processes of social and technological change within the next few years. Drawing on expert elicitation, an expert workshop, and a review of literature, which provides a comprehensive analysis on this topic, we propose concrete interventions to induce positive social tipping dynamics and a rapid global transformation to carbon-neutral societies. These social tipping interventions comprise removing fossil-fuel subsidies and incentivizing decentralized energy generation, building carbon-neutral cities, div...
