The current study shows one thing above all: it will be very, very tight for the 1.5-degree limit. It is almost irrelevant whether the budget is used up in six years – as this study suggests – or in ten years, as previously thought, if emissions remain the same. It's extremely tight either way. And that's not a new finding."
"But that in no way means we should give up, quite the opposite. It shows that every ton of carbon dioxide saved is all the more important because the budget is so extremely tight. And even if the multi-year average temperature increase exeeds 1.5 degrees, it's good to have saved as many emissions as possible beforehand, because every ton saved leads to less global temperature increase and therefore less damage."
"Even if the 1.5 degrees is exceeded for a period of time, the global mean temperature could decline down once emissions are reduced to zero and more CO2 is removed from the atmosphere. For that, too, it's beneficial if less was emitted beforehand."
"The extreme temperatures and accompanying droughts, storms and extreme weather events of this past year in particular have shown that we simply cannot adapt to uncontrolled climate change. This study is another call to go into emergency mode and do everything we can to reduce greenhouse gas emissions as quickly as possible.
