Limiting climate risks for finance: Central banks and science publish scenarios
06/07/2021 - To improve climate related risk management in the financial sector and facilitate a smooth transition toward a sustainable economy, over 90 central banks and financial market supervisors organized in the Network for Greening the Financial System joined forces with science. Together, researchers and financial experts now published an updated set of scenarios of an orderly transition, delayed transition, and climate policy failure. They show how early greenhouse gas emissions reductions can minimize both physical and financial risk. In contrast, delayed action or no action would inevitably drive up costs in the medium to long term. The analysis provides sectoral and regional detail to help financial institutions adapt their investment strategies.

Tipping elements can destabilize each other, leading to climate domino effects
06/03/2021 - Under global warming, tipping elements in the Earth system can destabilize each other and eventually lead to climate domino effects. The ice sheets on Greenland and West Antarctica are potential starting points for tipping cascades, a novel network analysis reveals. The Atlantic overturning circulation would then act as a transmitter, and eventually elements like the Amazon rainforest would be impacted. The consequences for people would reach from sea-level rise to biosphere degradation. Interactions in the network can lower the critical temperature thresholds beyond which individual tipping elements begin destabilizing on the long-run, according to the study – the risk already increases significantly for warming of 1.5°C to 2°C, hence within the temperature range of the Paris Agreement.

Parts of Greenland may be on the verge of tipping: new early-warning signals detected
05/18/2021 - Scientists have detected new early-warning signals indicating that the central-western part of the Greenland Ice Sheet may undergo a critical transition relatively soon. Because of rising temperatures, a new study by researchers from Germany and Norway shows, the destabilization of the ice sheet has begun and the process of melting may escalate already at limited warming levels. A tipping of the ice sheet would substantially increase long-term global sea level rise.

Few realistic scenarios left to limit global warming to 1.5°C
05/14/2021 - Of the over 400 climate scenarios assessed in the 1.5°C report by the Intergovernmental Panel on Climate Change (IPCC), only around 50 scenarios avoid significantly overshooting 1.5°C. Of those only around 20 make realistic assumptions on mitigation options, for instance the rate and scale of carbon removal from the atmosphere or extent of tree planting, a new study shows. All 20 scenarios need to pull at least one mitigation lever at "challenging" rather than "reasonable" levels, according to the analysis. Hence the world faces a high degree of risk of overstepping the 1.5°C limit. The realistic window for meeting the 1.5°C target is very rapidly closing.

Hydrogen instead of electrification? Potentials and risks for climate targets
05/06/2021 - Hydrogen-based fuels should primarily be used in sectors such as aviation or industrial processes that cannot be electrified, finds a team of researchers. Producing these fuels is too inefficient, costly and their availability too uncertain, to broadly replace fossil fuels for instance in cars or heating houses. For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense. Universally relying on hydrogen-based fuels instead and keeping combustion technologies threatens to lock in a further fossil fuel dependency and greenhouse gas emissions.

Fair climate policy could help reduce extreme poverty
04/27/2021 - Ambitious climate policies could help to reduce extreme poverty in developing countries. This is the result of a new study by scientists of the Potsdam Institute for Climate Impact Research (PIK) – a result that is in contrast to wide-spread assumptions that climate change mitigation comes with a trade-off for poverty reduction. To turn climate policies and poverty reduction into a win-win situation for planet and people, a progressive redistribution of emission pricing revenues and a fair international burden sharing are key.

The new EU climate target will increase carbon prices and could phase out coal power in Europe as early as 2030
04/27/2021 - Tightening the EU emissions trading system (EU ETS) in line with the EU Green Deal would dramatically speed up the decarbonization of Europe's power sector – and likely cause a demise of the coal industry. In a new study a team of researchers from Potsdam, Germany has quantified the substantial shifts Europe's electricity system is about to undergo when the newly decided EU climate target gets implemented. Higher carbon prices, the authors show, are not only an inevitable step to cut emissions – they will also lead much faster to an inexpensive electricity system powered by renewable energies.

Solar panels are contagious - but in a good way: study
04/21/2021 - The number of solar panels within shortest distance from a house is the most important factor in determining the likelihood of that house having a solar panel, when compared with a host of socio-economic and demographic variables. This is shown in a new study by scientists using satellite and census data of the city of Fresno in the US, and employing machine learning. Although it is known that peer effects are relevant for sustainable energy choices, very high-resolution data combined with artificial intelligence techniques were necessary to single out the paramount importance of proximity. The finding is relevant for policies that aim at a broad deployment of solar panels in order to replace unsustainable fossil fueled energy generation.
