An influential panel of UN scientists has warned in a major report that time is running out to tackle global warming. The panel urges governments to act immediately, warning that there could be as few as eight years left to avoid a dangerous global average rise of 2C or more. The warning came in the third report this year from the Intergovernmental Panel on Climate Change (IPCC) which was published May 4 in
The experts maintain that energy efficiency, renewable electricity sources and new technology to dump carbon dioxide underground can all help to reduce greenhouse gas emissions. In their report the scientists say that most of the technology needed to stop climate change in its tracks already exists, but that governments must act quickly to force through changes across all sectors of society. Delays will make the problem more difficult, and more expensive.
The report concluded that significant progress could be made in the next 25 years with known technologies and policy shifts, but would still need to be followed by a century-long transition to new energy sources that come with no climate impacts. The report concluded that if the world continues on its present course, emissions will rise by 25 to 90 per cent by 2030 compared to 2000.
