The News That Matters about the Nuclear Industry Fukushima Chernobyl Mayak Three Mile Island Atomic Testing Radiation Isotope

Climate action is going in the right direction, but what now? What is a realistic aim?

 The world’s 1.5°C climate goal is slipping out of reach – so now what?
Scientists say it is still theoretically possible to limit global warming
to 1.5°C, but realistically that now seems practically impossible.

Should we admit our failure and double down on holding warming below 2°C? As
scientists frequently point out, 1.5°C isn’t a cliff edge. It isn’t a
precisely calculated moment at which we know we will hit tipping points
that turn the Amazon into a savannah or commit Antarctica’s ice sheets to
a rapid collapse.

While most scientists maintain that 1.5°C is still
technically possible, the majority of those New Scientist spoke to think
the goal will be missed. The idea of conceding that prospects for hitting
1.5°C are dead might seem irredeemably gloomy.

But it is worth remembering
the path we were on before the world adopted the goal in 2015. Five years
earlier, climate pledges globally had us on track for up to 5°C of warming
by 2100, an apocalyptic level that would be almost impossible to adapt to,
given that we are already struggling to do so after heating Earth by just
over a degree.

Humanity shifted the goalposts at Paris, prioritising 1.5°C
over 2°C. We have made significant progress to even have a chance of
landing somewhere between the two. History may yet judge failure on 1.5°C
as a success, given how much the rallying cry has dragged societies in the
right direction.
