Australia and the rest of the world must virtually eliminate the use of coal for electricity within 22 years if there is to be a chance to save even some of the Great Barrier Reef, the world's most authoritative climate science body has warned.

| Extreme weather events will become more common and severe as temperatures increase. |
In a report authored by more than 90 scientists, and pulling together thousands of pieces of climate research, the UN's Intergovernmental Panel on Climate Change (IPCC) said global emissions of greenhouse gas pollution must reach zero by about 2050 in order to stop global warming at 1.5 degrees Celsius.
At current rates, they said 1.5C would be breached as early as 2040, and 2C would be breached in the 2060s.
If that happens, temperatures over many land regions would increase by double that amount. And at 2C of warming, the authors warn the world would risk hitting "tipping points", setting a course towards uncontrollable temperatures.
