A sweeping new UN-sponsored review of climate science published Monday shows global temperatures are rising faster than at any other point in the past 2,000 years — and that atmospheric carbon dioxide concentrations were higher in 2019 than at any time in at least 2 million years.
The report, by the Intergovernmental Panel on Climate Change (IPCC), says the world will cross a crucial temperature threshold (a rise of around 1.5 degrees Celsius) as early as 2030, one decade sooner than expected. Moreover, some devastating consequences of global warming are now unavoidable.
