Nature Artikel: Climate tipping points — too risky to bet against
Timothy M. Lenton, Johan Rockström, Owen Gaffney, Stefan Rahmstorf, Katherine Richardson, Will Steffen & Hans Joachim Schellnhuber

The growing threat of abrupt and irreversible climate changes must compel political and economic action on emissions.
"... The Intergovernmental Panel on Climate Change (IPCC) introduced the idea of tipping points two decades ago. At that time, these ‘large-scale discontinuities’ in the climate system were considered likely only if global warming exceeded 5 °C above pre-industrial levels. Information summarized in the two most recent IPCC Special Reports (published in 2018 and in September this year) suggests that tipping points could be exceeded even between 1 and 2 °C of warming (see ‘Too close for comfort’). ..."

Energiezukünfte. Wissen, beraten, gestalten
Wie kann die Transformation des Energiesystems gelingen? Die Wege dahin sind vielfältig und stellen eine zentrale Herausforderung dar. Für die Technikfolgenabschätzung stellt sich die Frage: Wie kann und wie soll Wissen über mögliche Zukunftspfade in der Forschung generiert und gesellschaftlich diskutiert werden?

OneEarth/Stanford: Impacts of Green New Deal Energy Plans on Grid Stability, Costs, Jobs, Health, and Climate in 143 Countries

A global effort to transition to 100 percent renewable energy by 2050 would cost nations $73 trillion upfront — but the expense will pay for itself in under seven years, according to a new report from researchers at Stanford University. The study also found that the shift to a zero-carbon global economy would create 28.6 million more full-time jobs than if nations continue their current reliance on fossil fuels.

On September 10, 2019, the Global Commission on Adaptation released its flagship report,
Adapt Now: A Global Call for Leadership on Climate Resilience.

The report puts forward a bold vision for how to transform key systems to be more resilient and productive. It is designed to inspire action among decision-makers, including heads of state and government officials, mayors, business executives, investors and community leaders.

Report authors found that adaptation can produce significant economic returns, as well as numerous social and environmental benefits. Specifically, the analysis found that investing $1.8 trillion globally in five areas from 2020 to 2030 could generate $7.1 trillion in total net benefits. The five areas include: early warning systems, climate-resilient infrastructure, improved dryland agriculture, mangrove protection and resilient water resources. These areas represent only a portion of the total investments needed and total benefits available.
