Earth to warm up to 2.9C even with current climate pledges: UN
economictimes.indiatimes.comUN said Monday, urging G20 nations to boost emissions cuts.
The UN Environment Programme's annual Emissions Gap report is released just ahead of crucial COP28 climate talks in Dubai and will feed into the global response to a sobering official «stocktake» of the failure to curb warming so far.
With this year expected to be the hottest in human history, UNEP said «the world is witnessing a disturbing acceleration in the number, speed and scale of broken climate records».
Taking into account countries' carbon-cutting plans, UNEP warned that the planet is on a path for disastrous heating of between 2.5C and 2.9C by 2100.
Based just on existing policies and emissions-cutting efforts, global warming would reach 3C.
But the world continues to pump record levels of greenhouse gases into the atmosphere, with emissions up 1.2 per cent from 2021 to 2022, UNEP said, adding that the increase was largely driven by the burning of fossil fuels and industrial processes.
UNEP chief Inger Andersen said G20 nations the world's wealthiest economies responsible for around 80 percent of emissions need to lead on reductions, but noted some were in «snooze mode».
