Farmers and those involved in tourism are expected to face the most challenges when it comes to tackling global warming.

The Intergovernmental Panel on Climate Change is warning the world has just a decade to limit future temperature rise to 1.5 degrees, and avoid calamitous impacts of climate change.

Lead report author Bronwyn Hayward told Mike Yardley it will be challenging to reach net zero carbon emissions by 2050.

"It is particularly challenging for farmers because it's asking for 35 percent cuts to methane from 2010. Also, the transport industry will face challenges, especially a country that depends on tourism."
