It's feared global warming could see temperatures rise by as much as 3 degrees by the end of the century.
A new report by the world's leading climate experts is due to be published later this afternoon.
The Intergovernmental Panel on Climate Change will issue a series of policies and actions that could stave off the worst effects of global warming.
In 2018, scientists warned emissions must be halved by 2030 to try to hold temperature increases to 1.5 degrees Celsius.
Former President of Ireland, and leading climate activist Mary Robinson, says there's huge potential to prevent further climate change, but the current forecast is disastrous.
"It's a paradox, we are literally on the cusp of a cleaner, healthier fairer world.
"We can get there, but we're headed for a 2.4 degrees world of warming at best, if all the governments, corporations, and investment did everything that they currently promised."
"It's more likely to be a 2.7 or even three degrees, which is catastrophic."
