Breaking News - Study warns glacier melting already passed the point of no return

Nothing that humans do now will limit the melting of glaciers over the next 100 years, according to new research.Scientists from two European universities concluded that 'even if all emissions were curtailed' the melting of glaciers during the following 100 years would not be stopped.However, the researchers did confirm that humans' actions now can impact climate change in the long run.The new analysis was published in Nature Climate Change.The Paris Agreement brought about a pledge from 195 nations to hinder the rising global average temperature.The participating countries agreed to limit this rise to about two degrees Celsius higher than pre-industrial levels.The countries decided to limit it to one-and-a-half degrees above those levels if possible.The new report confirmed that 'this should significantly reduce the risks of climate change'.But the researchers behind the new study wanted to determine how this would potentially affect glaciers.They learned that - at least until 2118 - it will not make a difference; only after the next 100 years will researchers see the effects of these efforts on melting glaciers.Glaciologist Georg Kaser, who worked on the new report, said: 'Melting glaciers have a huge influence on the development of sea level rise.'In our calculations, we took into account all glaciers worldwide - without the Antarctic and Greenland ice sheets and peripheral glaciers - and modeled them in various climate scenarios.'The new study said that 15 kilograms of glacier ice are the cost of one kilogram of emitted CO2.'Whether the average temperature rises by two or only one-and-a-half degrees Celsius makes no significant difference for the development of glacier mass loss over the next 100 years,' the report said.Researcher Ben Marzeion explained that about 36 percent of all ice stored in today's glaciers will melt with or without further greenhouse gas emissions.'That means more than a third of the glacier ice that still exists today in mountain glaciers can no longer be saved even with the most ambitious measures,' Marzeion said.But in the long run, the distinction between the two degrees goal and the one-and-a-half degrees goal makes a difference, the report said.Kaser said: 'Glaciers react slowly slowly to climatic changes. If, for example, we wanted to preserve the current volume of glacial ice, we would have to reach a temperature level from pre-industrial times, which is obviously not possible.'In the past, greenhouse gas emissions have already triggered changes that can no longer be stopped. This also means that our current behavior has an impact on the long-term evolution of the glaciers - we should be aware of this.'The report said that if nations want to make a tangible difference that can stop the melting of glaciers they need to be aware of what just one kilogram of CO2 emissions does to the environment.Marzeion said: 'Calculated on the basis of an average car newly registered in Germany in 2016, this means that one kilogr AutoNews- Source:
