UK scientists say the fires in Australia are a taste of what the world will experience as temperatures rise. Australia is now about 1.4C warmer than the global average temperature was in the pre-industrial period.
“These are impacts we are seeing for one degree of global climate change. The impact will get worse as long as we don’t do what it takes to stabilise the world’s climate,” said Prof Corinne Le Quéré, from the University of East Anglia in Norwich.
“And what it takes is to bring CO2 and other long-lived greenhouse gases down to net zero emissions. If we don’t do it, we will have much worse impacts – so what we are seeing in Australia is not the new normal, it’s a transition to worse impacts.” As the climate becomes drier and hotter, future fires in the Amazon could be more damaging than last year’s, according to a new study. Authors of the study project that the amount of forest burned could double by 2050 and consume 16% of the rainforest. That outcome would imperil the Amazon’s ability to fight climate change, to the point that the forest could begin contributing more planet-warming gases than it absorbs.
