The United Nations UN says while plans submitted by most signatories to the Paris Agreement will reduce global greenhouse gas emissions, they are still not ambitious enough to limit global temperature rise to 1.5 degrees Celsius by the end of the century.

The UN gave the warning in a report published by the UN Climate Change.

The current combined National Determined Contributions NDCs meaning the countries’ national efforts to tackle emissions and mitigate climate change are leading the planet to at least 2.5 degrees of warming.

This is a level deemed catastrophic by scientists at the Intergovernmental Panel on Climate Change IPCC.

In 2019, the IPCC indicated that to curb global warming, CO2 emissions needed to be cut by 43 per cent by 2030, compared to 2010 levels, but current climate plans show a 10.6 per cent increase instead.
