COP29 The world must reach carbon neutrality much sooner than planned.

World leaders offered conflicting views on how to tackle climate change at a UN-led meeting on Wednesday, as a new report warned the world must reach carbon neutrality much sooner than planned. Planet-warming carbon dioxide emissions from oil, gas and coal rose to a new record this year, according to preliminary research by the Global Carbon Project, an international network of scientists.

The news came as leaders gathered in Azerbaijan for the COP29 climate talks, aiming to reach an agreement to increase funding to help poorer countries adapt to climate shocks and transition to cleaner energy.

To keep the Paris Agreement's ambitious target of limiting warming to 1.5 degrees Celsius within sight, the world would now need to achieve net zero CO2 emissions, research has found _to the end of the 1930s - instead of 2050. (Laurent THOMET, more at phys.org)
