Weather extremes such as heat waves that up to now were highly unusual are likely to become the new normal, according to a report by the Potsdam Institute for Climate Impact Research (PIK) now launched by the World Bank. Climate Change impacts are already being felt today and will grow even if warming is limited below 2 degrees. However, with unabated warming of probably 4 degrees within our century, the consequences increase drastically. The report is the third in a series, entitled “Turn down the heat” by the World Bank.
The new report focuses on how climate impacts and social vulnerability interact, or how the poor are hit hardest in Latin America and the Caribbean, Middle East and North Africa, and East and Central Asia.
“The impacts in the various regions around the world are enormously diverse, yet two things become clear in our report: almost no region will ultimately be safe, and the risk for the people on the ground is greatest in places where several impacts overlap,” says Christopher Reyer of PIK who coordinated the report that is a result of a cooperation with Climate Analytics (CA) and the UK Overseas Development Institute (ODI). “In cities in the Andes mountains, for instance, populations are likely to experience seasonal water scarcity, while in the same time food prices will increase and extreme weather events create additional stress.”
**Analyzing science to nderstand the risks**
It is this risk perspective that is a defining characteristic of the “Turn down the heat” reports, says Reyer. “We analyze existing climate science findings to identify which are the impacts that really make a difference.” Bill Hare, also a lead author of the report, adds: “Assessing the entire chain of climate impacts - for example, how heat waves trigger crop yield declines and how those trigger health impacts - is key to understanding the risks that climate change poses to development.”
The results are worrying. In the Caribbean, coral reefs are threatened of significantly higher probabilities of annual bleaching already at 1.5-2 degrees warming, affecting fisheries, tourism and coastal hurricane protection. At 4 degrees, most of the land area in all regions studied will be affected by highly unusual and potentially devastating heat extremes.
**“Impacts hit the global poor” - but there are options for action**
“Tackling climate change is a matter of reason, but also of justice,” says the report’s lead-author Hans Joachim Schellnhuber, director of PIK. “Global warming impacts in the next decades are likely to hit those hardest that contributed least to global greenhouse gas emissions: the global poor.” Developing countries are expected to experience the most severe climate impacts, notably in the tropics, while lacking the means to build resilience. And within these countries, again those parts of the population with the least means are most vulnerable to additional stress.
Climate change impacts hence “make it more difficult to reduce poverty and put in jeopardy the livelihoods of millions of people. They also have serious consequences for development budgets, and for institutions like the World Bank Group, where our investments, support and advice must now also build resilience and help affected populations adapt,” says Jim Yong Kim, President of the World Bank Group. “The good news is that we can take action that reduces the rate of climate change and promotes economic growth, ultimately stopping our journey down this dangerous path. World leaders and policy makers should embrace affordable solutions like carbon pricing and policy choices that shift investment to clean public transport, cleaner energy and more energy efficient factories, buildings and appliances.”

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
