From natural science to social science, from risks to solutions, from identifying Planetary Boundaries to managing Global Commons: The Potsdam Institute for Climate Impact Research PIK is advancing the frontier of integrated research for global sustainability, and for a safe and just climate future. A member of the Leibniz Association, the institute is based in Potsdam, Brandenburg and connected with the global scientific community.

Drawing on excellent research, PIK provides relevant scientific advice for policy decision-making. This is O — for a safe tomorrow.

Global Warming And Its Effects

Almost all of industry energy needs in Europe can be satisfied with clean power by Replacing fossil fuels with low-CO2 electricity is key to stabilize our climate. However, industry electrification leads to greenhouse gas emissions reductions only if power generation gets greener.

Ocean floor deposits and model calculations have confirmed that in the past 3 million years, the global mean temperature has never been more than two degrees above pre-industrial levels, with fluctuating CO2 levels in the atmosphere. Since the beginning of industrialization, more CO2 has accumulated in the atmosphere through the burning of coal, oil and gas than probably ever before in the past 3 million years.

Global Warming And Its Effect On The Global Environment

Effecst Thus, in our current century, there is real threat that without effective climate policy the 2-degree limit of global warming will be breached for the first time — with far-reaching consequences. Around a quarter of the greenhouse gases emitted worldwide are from agriculture and forestry including, for example, deforestation. This makes land use one of the biggest sources of emissions, like especially methane and CO2, and thus a driver of climate change. However, it is also itself strongly affected by climate impacts, because, for example, there are more frequent regional crop failures due to droughts or heavy rainfall.

Land use is therefore an important part of the solution to the climate problem. Better land use management — for example through more efficient use of fertilizers, reforestation or the renaturation of peatland soils — as well as a reduced demand for animal products can help to stabilize our climate.

Researchers use computers to solve large multidimensional equations and thus simulate processes in the Earth system. These https://amazonia.fiocruz.br/scdp/blog/woman-in-black-character-quotes/the-growing-issue-with-childhood-obesity.php models contain our knowledge of the physics of the planet. Whether they reliably reproduce temperature curves in past cold and warm periods can be checked using data from measurements or from natural climate archives such as ice drill cores. Models can then be used to calculate future developments - always based on certain assumptions, for example about the increase in CO2 emissions.

The result are projections: not predictions, but complex if-then statements. People around the world are being hit hard by Corona - nothing about this tragedy is positive. The emission of CO2 has decreased because in many places airplanes and factories have stood still.

However, the amount of greenhouse gas in the atmosphere is not decreasing because so much CO2 has already accumulated there; it will last and stay there for thousands of years.

Also, the stabilization of our climate cannot under any circumstances be achieved by a socially devastating reduction of our economy, as we https://amazonia.fiocruz.br/scdp/blog/culture-and-selfaeesteem/political-factors-that-affect-international-business.php now observe in some places due to the pandemic. Rather, the solution must be a targeted transformation of our economy — towards clean technologies.

Some parts of the earth system show Hu,ans threshold behavior: If they are stressed beyond their respective critical limits by human-made climate change, strong and sometimes unstoppable and irreversible changes can occur — they topple over, to put it simply.]
