The Intergovernmental Panel on Climate Change (IPCC) has issued its the most extensive warning on the risks of rising global 
temperatures.The panel released their report after three years of research and a week of intense debate between scientists and government officials at a meeting in South Korea.
The report says the world is now completely off track, heading towards increase of 3 degree Celsius.
The report pleads to keep the target of 1.5 degree Celsius above pre-industrial level. And for this, the report suggests that rapid, far-reaching and unprecedented changes in all aspects of society are required.
The report concludes by saying that though the target will be hugely expensive, but the window of opportunity remains open.
