ASATUNEWS - United Nations ( UN ) would recommend member states to reduce greenhouse gas emissions drastically . This is to meet international goals to reduce the impact of global warming .
Based on current emissions trends , the projected global temperatures rise 2 degrees Celsius above pre-industrial levels . This increase will occur in less than 30 years , according to a summary of the draft report seen by The Wall Street Journal .
The projections indicate that the global temperature rise above 2 degrees would potentially increase the risk of natural changes that are too large , such as the melting of the Greenland ice sheet .
Countries should reduce emissions by at least 40 % by 2050 from the 2010 level of emissions in order to have a 50-50 chance to avoid these changes , concluded a report prepared for the Intergovernmental Panel on Climate Change ( IPCC) .
The report will be presented in Berlin on Sunday tomorrow as the third part of a four- part comprehensive report of the IPCC.
In its report , the IPCC is also likely to provide an option to combat climate change , such as expanding the use of renewable energy and storing greenhouse gases underground .
Jean - Pascal van Ypersele , vice- chairman of the IPCC and the Université catholique de physicist at Louvain in Belgium , declined to comment on the report with specifics . However, van Ypersele said the scope of the report is broader than just an assessment of the challenges faced in reducing the impact of global warming .
" This report will show that humans already have all the means to be able to change the path of life " which now is leading to global warming , he said .
Earth has warmed about 0.8 degrees Celsius since 1900 , according to climate scientists . In 2010 , some 200 countries agreed to reduce emissions so that the Earth does not penetrate the two-degree limit .
" In the last 10 years , emissions have increased dramatically , " said Bob Ward , policy and communications director at the Grantham Research Institute on Climate Change and the Environment in London . " Opportunities to [ avoid ] the rise of two degrees is still open , but [ the effort to achieve it ] will be more expensive . "
Carbon dioxide is the main greenhouse gas , and is one of the biggest sources of electricity production . According to the draft IPCC report , if there is no substantial improvement in electrical efficiency , direct emissions from " energy supply sector global" predicted " will go up two or three times that in 2050 .
