The UN Emissions Gap report indicates that if only “current policies” are implemented the world could warm by up to 3.1C. This would be “catastrophic” for the world according to the UN, leading to dramatic increases in extreme weather events including heatwaves and floods.

Despite the recent deployment of clean tech in the U.S. and other countries, the world is still on course to hurtle past the temperature goals in the Paris Agreement, a U.N. report issued Thursday warns.

The United Nations Environment Programme has called for a 42% cut in annual global greenhouse gas emissions by 2030 to limit warming to 1.5 degrees Celsius, urging G20 nations to heighten their climate action.

In a report on the emission cuts needed to limit global warming to 1.5°C, the UN said the goal would 'soon be dead' without a global mobilisation on a scale and pace never seen before.

World on track for ‘catastrophic’ 3.1C of global warming this century, UN warns - International goal to limit warming to 1.5C will ‘soon be dead’ without a massive mobilisation to cut climate emissions,
