Two key statements, the report of the IPCC, both are not really new. And that is the disturbing message of the report.
The sea level is rising faster than previously thought. This is a key message of the fifth World Climate Report, which the IPCC presented this Friday in Stockholm.
The biggest climate change, the sea level increased according to the report by the end of this century, at least 26 centimeters. In the worst case, there are 82 centimeters. “While heating the oceans and melting glaciers and ice sheets, global sea level will continue to rise, but faster than we have seen in the last 40 years,” said one of the co-chairs of the relevant Working Group 1, the Chinese climate scientists Qin Dahe .
The second key message that the international community is threatening their goal of limiting global warming to two degrees to clear miss. The temperatures on earth could by 2100 – depending on the scenario – increase by 1.5 to 4 degrees Celsius above pre-industrial era. 0.8 degrees which are already achieved. If the temperature increases by more than two degrees above pre-industrial era scientists fear uncontrollable environmental consequences.
“climate chancellor Angela Merkel must be again,” the president of the German Nature and Environment, Hartmut Vogt man said, in a first reaction to the report. In November, the annual World Climate Conference will take place in Warsaw. It is already the thirteenth. With probability bordering on certainty, it is also there be no real breakthrough.
Kiribati prepares for the fall before
Only on Wednesday, the President of Kiribati, Anote Tong, strongly warned against the destruction of his Pacific island nation. “Sea level rise threatens the survival of our people,” Tong said before the UN General Assembly in New York.
“What we are currently experiencing on the low-lying atolls, is just a warning of what we will experience. Nobody will be spared. We can not continue to abuse our planet.” The fight against climate change will not currently occurring committed enough, so Tong. “We are disastrously off course.”
His country stronglyneed the help of the international community to deal with the consequences of climate change and to prepare the people of Kiribati on his uncertain future, Tong said. For example, his government was already in further developing the professional skills of the inhabitants of Kiribati. “We want them to have the opportunity to emigrate with dignity.”
“Climate skeptics lose a battle”
that climate change is man-made, doubt only hard science deniers. The IPCC is itself than in its previous report in 2007 that man has in his new report, more secure, the main responsibility for global warming. The UN body had not provided the chance in the fourth assessment report, 90 percent, he now described the theory as “extremely likely.” – A term that describes a probability of 95 percent
the final of the World Climate Report had negotiated government officials and researchers since Monday. It is traditionally a matter mitigate certain statements or to prevent such a slowdown. The German government officials were reportedly traveled, for example, with the mission to Stockholm, to prevent the reporting of a “pause” in global warming is the question.
fact, a slowdown in the global warming observed – that is indisputable. The so-called climate skeptics, behind which lobby groups are not uncommon, although this slowdown take this opportunity to announce the end of climate change. The arguments are always the same: Carbon dioxide is good for the vegetation and have greater influence no influence on the climate, the temperature of the sun will
.However
of science are those positions at most a marginal phenomenon. On now published the first part of the new world climate report 259 lead authors have been working for four years, supported by hundreds of other researchers. According to the UN climate chief Christiana Figueres, the new climate report is a “wake up call”. The skeptics who deny a climate change would “just lose a battle,” said the head of the UN Climate Secretariat.
warming does not run straight
“Climate change does not take a break,” said Guy Brasseur, one of the main authors of the last report and director of the Climate Service Center in Hamburg. The earth by greenhouse gases continue to take a lot of energy from the sun. “Only they warmed currently just not so much the layers of air above the ground, but the oceans.”
any case, the increase in the air temperature does not run straight, but is subject to fluctuations: If only the curve of the last 15 years, look at them, will think that the global temperature decrease. Over the last 100 years, however, it is clear that global warming is increasing steadily.
climate calculations, therefore, consider changes in 30 years, and not short-term fluctuations, says Brasseur. “I think in the last report, we have not made such phenomena clearly. This was a mistake by the science,” the researcher says.
Many questions are still open
More about
the melting ice of glaciers and Poland take on heat, and the sun shine in its own cycle. Both, however, can not explain the current downturn in air temperature rise, says Brasseur.
climate scientists concede quite that many questions are still open. “The big question mark is mainly the oceans, but also the clouds and dust particles in the atmosphere,” says climate researcher Ulrich Cubasch, a professor at the Free University of Berlin and one of the two main authors of the introduction of the new Climate Report.
The general direction of future global warming but is confirmed in any case. Today there are more detailed knowledge, so that the new report would break down global warming regions on stronger than the last. “We are constantly making new projections taking into account new data, especially from new ocean probes and satellites,” said Cubasch. “That then the answers of today are not the same as 20 years ago is clear, otherwise we would have to save the work ourselves.”
The full report appears on this Monday. Parts 2 and 3 of 5 World Climate Report deal with the effects of climate change and policy options to slow him down. They will be presented in spring 2014 in Japan and Berlin.
