Bad weather, heavy rains, thermal records - today we feel the first effects of global warming. The UN Intergovernmental Panel on Climate Change (IPCC) published a report that outlined its possible consequences, Die Welt reported.. Humanity must act immediately, experts urge.

"Three years ago, 196 countries made very serious commitments under the Paris Climate Agreement. The goal is to limit global warming to 1.5 degrees Celsius compared to the pre-industrial era. This is possible only if large-scale measures are taken to reduce the emission of carbon dioxide into the atmosphere, ”notes publication author Sarah Maria Breh.

According to the IPCC report, which will be published on Monday, by 2030 it is necessary to reduce carbon dioxide emissions by 45% compared with 2010, and by mid-century to zero.

"As a result of industrial activity, heating, power generation, construction, traffic and agriculture, a person ejects so much CO2 into the air" that he begins to accumulate there, heating up the planet. This is the "greenhouse effect", two thirds of the blame for which lies on carbon dioxide, the journalist reports.

According to Niklas Hoene, professor of ecology at the University of Wageningen (Netherlands), in order to reduce carbon dioxide emissions to zero by 2050, it will be necessary to make significant changes in all spheres of human life. "We need to change our behavior - technical solutions alone will not be enough," he is sure..

That's the problem. We have long known what should be changed, the author writes. "Fly less, consume less meat, drive less often. As for Germany, here we are talking primarily about reducing the amount of coal burned ".

"For politicians, climate goals pose a problem. Who wants to tell their voters that they now have to give up cheap flights on vacation or beef at an attractive price? Who wants to quarrel with industry and major energy companies? Hardly anyone is ready today to limit himself in many respects only because scientists warn mankind about the destructive consequences of our way of life in the future.. However, - the author notes, - we are talking not about the future, but about the present ".

The effects of global warming are already felt today.. These are extreme weather conditions, the rise of the level of the World Ocean, and the melting of the ice of the Arctic.

"For a long time, scientists tried to calculate the effects of climate change using statistics," the article says.. "But events have always been ahead of us. While we were doing calculations, something was already happening, "says Anders Levermann of the Potsdam Institute for Climate Research. For five years now, researchers have been working on the analysis of physical cause-effect chains of weather disasters.. These studies give a chance to make, though rough, but timely forecasts, noted further.

As Leuvermann observes, if humankind fails to reduce warming to 1.5 degrees Celsius or the current boundary is exceeded, "our world will change dramatically. And we will face a climate about which we know nothing ".

The report lists possible changes: the sea level will rise by 10 cm by the end of this century - if another 2 degrees of warming occurs, not 1.5. The Arctic is likely to remain without ice at least once every 10 years, all coral reefs will die. "But even if it is taken for granted that the Earth warms up by 2 degrees, in the next 10 years, the same measures should be taken as to achieve the original goal," said Levermann.

Most scientists are skeptical about the fact that mankind will be able to achieve the goal of 1.5 degrees Celsius. According to Jacob Wahsmut from the Fraunhofer Institute, mankind in the coming years will emit such amount of greenhouse gases into the atmosphere that temperatures will rise by more than 1.5 degrees and in this case global warming can be stopped only by using negative emissions, removing carbon dioxide from the atmosphere. "Today we do not have the technical capabilities to do this," the article says..

"One thing is clear: our life will change in a fundamental way. In any case, "- the author summarizes.
