A global group of around 11,000 scientists have endorsed research that says the world is facing a climate emergency.
Here’s are six steps the researchers show should be taken to make a major difference -
Energy: Politicians should impose carbon fees high enough to discourage the use of fossil fuels, they should end subsidies to fossil fuel companies and implement massive conservation practices while also replacing oil and gas with renewables.
Short-lived pollutants: These include methane, hydrofluorocarbons and soot - the researchers say that limiting these has the potential to cut the short-term warming trend by 50% over the next few decades.
Nature: Stop land clearing, restore forests, grasslands and mangroves which would all help to sequester CO2.
Food: A big dietary shift is needed say researchers so that people eat mostly plants and consumer fewer animal products. Reducing food waste is also seen as critical.
Economy: Convert the economy's reliance on carbon fuels - and change away from growing the world's gross domestic product and pursuing affluence.
Population: The world needs to stabilise the global population which is growing by around 200,000 a day.
