global warming

What do people mean when they talk about the “1.5°C goal” in the context of climate change? What is the origin of this value and how is it quantified? What happens if we exceed it – is there any way back down below a global warming of 1.5°C? In this text, we look at the emergence of the 1.5°C goal of the Paris Agreement and explain why we need to keep it within reach.

Managing the hazards and risks posed by floods includes precautionary measures, preparation for a flood, hazard prevention during an event and post-event management, including reconstruction. The uniform application of flood risk management has been ensured in the EU-Flood Risk Management Directive since 2007.

Floods are natural events, they form on a regular basis and are an integral part of the water cycle. The occurrence of floods depends on the strength of precipitation, the characteristics of the catchment area and the morphology of the river itself. Humans can influence and intensify floods, their course and effects.

Climate change will affect the frequency, intensity and regional occurrence of extreme weather events and lead to gradual climatic changes. Although impacts appear locally at first, they spread beyond political borders due to the global physical and economic interconnectedness. A new UBA report provides an overview of the potential impact chains of global climate change on the German economy.

The Paris Agreement set the international goal of limiting global warming to 1.5°C. To achieve this, it is essential to rapidly reduce greenhouse gas emissions towards zero. Additional measures are needed to remove CO2 from the atmosphere, such as reforestation. However, UBA advises against betting on untried, risky technologies.

According to the IPCC, global warming must be limited to 1.5 degrees Celsius in order to mitigate the risks. An UBA position paper outlines how the EU climate policy could be aligned with this goal. Already by 2020, the parties to the Paris Agreement are to submit their updated national climate contribution to limit global warming. Up to now, far less has been promised than would be necessary.

Capital investments which target the energy, transport and building sectors can help to limit the rise in Earth’s temperatures to less than 2 degrees. A new UBA study proposes the criteria by which public financial institutions like development banks should proceed and identifies which projects should no longer be funded.
