Now or never: UN report urges rapid action on climate change

Substantial reductions in the use of fossil fuels are needed to tackle the climate crisis, a new UN report has warned. Meeting goals agreed by countries to limit temperature rises to 1.5C or below 2C to avoid the worst impacts of climate change requires rapid, deep and immediate greenhouse gas emissions cuts in all areas, it says. The UN’s Intergovernmental Panel on Climate Change (IPCC) science body has released the third part of its sixth assessment report, spelling out how to cut emissions by switching to increasingly cheap renewables and fuels such as hydrogen, as well as energy efficiency, capturing carbon and planting trees.
