Die Überlebensfrage der
Wenn es um Zukunft geht, scheint das Jahr 2100 die Grenze zu sein, bis zu der wir uns Gedanken machen. So hat der Pariser Klimagipfel festgelegt, dass bis zum Ende unseres Jahrhunderts die Klimaerwärmung um höchstens zwei Grad ansteigen soll. Was aber ist 2130, ein Jahr, das einige der heute Geborenen erreichen werden oder gar 2200, das viele Kinder der heute Geborenen noch erleben können?
Wer den Klimawandel ernst nimmt, muss den bisher angenommenen Zeithorizont erweitern.

The question of humanity's survival
When it comes to the future, the year 2100 seems to be the limit to which we think. For example, the Paris climate summit has stipulated that by the end of our century, global warming should increase by no more than two degrees. But what is 2130, a year that some of those born today will reach, or even 2200, which many children of those born today will still be able to experience?
In Bismarck's time, a German person lived to be 46 years old on average. Today, we will live to be about 83 years old on average, and many of those born today will live to be 100 and older. Biologists assume that our inner clock is set for about 150 years if we behave sensibly.
Anyone who takes climate change seriously must extend the time horizon assumed so far.
We can hardly think a thousand years ahead. But it should be 100 to 200 years. Because climate change affects many generations after us. Looking just 80 years ahead is not enough in a subject that has become a matter of humanity's survival. We should at least be interested in how hot it may get until the middle of the next century. That is the time our grandchildren and great-grandchildren will experience.
If we want to limit global warming to 1.5 degrees plus compared with 1880, which would already mean millions of climate refugees, we have just ten years left in which to emit greenhouse gases. If we do not want global warming to rise above two degrees, which would mean hundreds of millions of climate refugees in this century, we would - according to the current findings of climate research - still have 25 years to become climate neutral. But at present we are heading for global warming of about five degrees by the end of the 21st century.
As long as we continue to burn fossil fuels, the temperature will continue to rise. That means we're burning the future of our grandchildren and great-grandchildren. If we burn all the fossil fuels in the ground today, we are burning ourselves. I don't want to be my grandson then.
One thing is certain: ...global warming will remain a matter of survival for many centuries and millennia.
By 2020, the Arctic will be on average almost ten degrees warmer than the average of the last hundred years. This is why the permafrost soils in Siberia are thawing dramatically right now, releasing methane. A methane molecule is more than 20 times more harmful to the climate than a CO2 molecule. What we are doing today for or against climate change will have effects on centuries and millennia.
Not only is the Arctic already melting today three times faster than glaciologists feared ten years ago, but the Antarctic is also melting dramatically. As a tuition for Mr Trump and the German AfD: The Arctic is at the top and the Antarctic at the bottom and the Earth is not a disc!
If the Arctic and Antarctic melt away completely, the sea level will rise by up to 70 metres. Good luck then to Hamburg, Bremen and Bremerhaven.
In a new book ("Protect the Environment - The Dalai Lama's Climate Appeal to the World"), which will have been written together, the Dalai Lama reminds us that in just a few decades the melting of ice in the Himalayas will mean an unimaginable water catastrophe for two billion Indians and Chinese, because the largest rivers in Asia have their source in the Himalayas and will have less and less water in the future because of the melting of ice there.
The Greenland ice will reach its tipping point at the latest when global warming will have increased by 1.8 degrees. Climate scientists fear that the shifting of the Gulf Stream, further clearing of the Amazon forest or continued burning forests in Australia would be additional tipping points, and once they are reached there is no turning back.
It is up to us today to prevent the worst from happening in the next ten years if we want to keep our civilisation. That is the grace period we still have for the 100% switch to renewable energies. Probably never before in human history has a generation had so much power, but also so much responsibility for the next generations over centuries and millennia.
That is why we must now invest the state aid due after the Corona crisis in building a green and sustainable economy. Anything else is irresponsible.
