Climate-related risks depend on the speed of future warming. An increase to 2,0 degrees leads to significant changes, according to the IPCC.

Human activity has so far caused global warming to be 1,0 degrees from the pre-industrialization level. If this trend continues, global warming may reach 2030 degrees in 1,5. A rise to 2,0 degrees could have devastating effects. Sustainability is all the more important Lifestyle and the conscious use of natural resources.
The consequences of global warming for natural and human systems are clearly visible. Many land and marine ecosystems have changed due to global warming. Heat extremes, heavy rainfall and drought are the tangible consequences. In coastal areas also threaten salinisation and flooding.
Future climate-related risks depend on the rate of warming
An increase in global warming to 2,0 degrees would have far-reaching consequences. In particular, sea-level rise and glacier melt would expose the environment and humans to dangerous climate change. Limiting global warming to 1,5 degrees requires rapid change in all sectors of society, IPCC's World Climate Council stated in its "Special Report on Limiting Global Warming to 1,5 Degree".
It is about a drastic reduction of emissions in the areas of energy, industry, buildings, transport in cities and in the countryside. How far the path to zero emissions is, shows a number from the World Energy Outlook of BP: Humanity is currently emitting around 33 billions of tons of greenhouse gases each year. 66% of them are caused by six nations alone, including Germany.

In order to limit global warming to 1,5 degrees, 2030's emissions would have to be reduced by 2010 percent by the year 45 - and by 2050 by the latest, carbon dioxide emissions would have to be carbon neutral.
This can be achieved, for example, through the use of renewable energies or the afforestation of forests. According to Petteri Taalas, Secretary-General of the World Weather Organization, the technical means are given that ambition is lacking.
The following graphic from the BP Energy Outlook clearly shows the causes of the greenhouse gases. Energy consumption, growing population and wealth are leading to further increases in carbon dioxide levels under current conditions until 2040. Reduction by 40% or more can be achieved primarily through CO2-reduced energy consumption and increased efficiency in the industrial and transportation sectors. Above all, through the use of renewable energies and a low-carbon production and infrastructure.

Climate change impacts and responses are closely linked to sustainable development that reconciles social wellbeing, economic prosperity and environmental protection.
Politics, people and business are equally in demand. The Sustainable Development Goals of the United Nations (Agenda 2030United Nations Sustainable Development Goals (SDGs) provide a recognized framework for assessing links, including poverty eradication, inequality reduction and climate change mitigation. This can create many positive synergies.
But every single person is also in demand and can help to slow down climate change. In everyday life alone, there are countless ways to start with little things to save our planet. Please read our infographic with the 5 Ultimate Tips for Climate Protection.
