Drastic cuts to fossil fuel use. Growing forests and eating less meat. These are just some of the actions needed in this decade to contain global warming to 1.5 degrees Celsius above preindustrial temperatures, a major report by the U.N. climate science agency said Monday.

The result: global emissions are on track to blow past the 1.5ºC warming limit envisioned in the 2015 Paris Agreement and reach some 3.2ºC by century's end. "It's now or never," IPCC report co-chair Jim Skea said in a statement with the report – the last in a three-part series by the IPCC, with the next review cycle not expected for at least another five years.While other recent IPCC reports addressed the latest findings in climate change science as well as ways for the world to adapt to a warmer world, Monday’s tackled ways of curbing emissions – making it one of the more contentious reports of the pack for governments.

"Different countries have different interests," IPCC co-author and climate scientist Jan Minx. "Everyone wants to make sure that their concerns are addressed ... but scientists have the last word." "Most people assumed that demand reduction could be accomplished through efficiency improvements," said economic anthropologist Jason Hickel at the London School of Economics. "But the evidence we have now suggests that will not be enough in and of itself."
