Rainy days harm the economy

12/01/2022 - Economic growth goes down when the number of wet days and days with extreme rainfall go up, a team of Potsdam scientists finds. Rich countries are most severely affected and herein the manufacturing and service sectors, according to their study now published as cover story in the renowned science journal Nature. The data analysis of more than 1.500 regions over the past 40 years shows a clear connection and suggests that intensified daily rainfall driven by climate-change from burning oil and coal will harm the global economy.

Climate policy: How to protect emissions trading from excessive financial speculation

12/15/2021 - CO2 emissions trading – a key element of EU climate policy – can be protected from distortions driven by financial speculators, a new report shows. The price for CO2 emissions allowances in the EU cap-and-trade scheme has almost tripled in the course of this year, and is now subject to unprecedented volatility levels. Financial speculation is increasingly blamed for this price rally, but evidence is lacking whether this can actually endanger the functioning of the trading system for the most relevant greenhouse gas. The researchers propose tools to detect speculation, evidence a substantial risk from a new breed of investors, and suggest improvements for market oversight.

Too dry, too hot, or too wet: Increasing Weather Persistence in European Summer

12/06/2021 - Global warming makes long lasting weather situations in the Northern hemisphere‘s summer months more likely – which in turn leads to more extreme weather events, a novel analysis of atmospheric images and data finds. These events include heatwaves, droughts, intense rainy periods. Especially in Europe, but also in Russia, persistent weather patterns have increased in number and intensity over the last decades with weather extremes occurring simultaneously at different locations.

Accelerated renewables-based electrification paves the way for a post-fossil future: study

11/25/2021 - Cost-slashing innovations are underway in the electric power sector and could give electricity the lead over fossil-based combustion fuels in the world’s energy supply by mid-century. When combined with a global carbon price, these developments can catalyse emission reductions to reach the Paris climate targets, while reducing the need for controversial negative emissions, a new study finds.

New study: World map of the most important protected areas to avert a climate catastrophe

11/18/2021 - New research out today from Conservation International maps the places on Earth that humanity must protect to avoid a climate catastrophe. These ecosystems contain what researchers call “irrecoverable carbon,” dense stores of carbon that, if released due to human activity, could not be recovered in time for the world to prevent the most dangerous impacts of climate change.

High impact climate events: Better adaptation through earlier prediction

11/16/2021 - The prediction of high impact climate phenomena can be substantially improved by a new mathematical approach that analyses the connectivity and patterns between geographical locations, scientists say in a new publication. This can potentially save thousands of lives and avoid billions in economic losses. Prediction times for events like El Niño, monsoons, droughts or extreme rainfall could be increased substantially, to a month or in some cases even a year in advance, depending on the type of the event. The new framework can thus become key for improving adaptation to the global warming crisis.

The Ripple Factor: Economic losses from weather extremes can amplify each other across the world

27/10/2021 - Weather extremes can cause economic ripples along our supply chains. If they occur at roughly the same time the ripples start interacting and can amplify even if they occur at completely different places around the world, a new study shows. The resulting economic losses are greater than the sum of the initial events, the researchers find in computer simulations of the global economic network. Rich economies are affected much stronger than poor ones, according to the calculations. Currently, weather extremes around the world are increasing due to greenhouse gas emissions from burning fossil fuels. If they happen simultaneously or in quick succession even at different places on the planet, their economic repercussions can become much bigger than previously thought.

Unprecedented rise of heat and rainfall extremes in observational data

10/7/2021 - A 90-fold increase in the frequency of monthly heat extremes in the past ten years compared to 1951-1980 has been found by scientists in observation data. Their analysis reveals that so-called 3-sigma heat events, which deviate strongly from what is normal in a given region, now on average affect about 9 percent of all land area at any time. Record daily rainfall events also increased in a non-linear way – on average, 1 in 4 rainfall records in the last decade can be attributed to climate change. Already today, extreme events linked to human-caused climate change are at unprecedented levels, the scientists say, and they must be expected to increase further.
