We're screwed

 ... The only question is, how badly.

2023 was the hottest year on record, 1.48C above the pre-Industrial Revolution average.

The planet was 1.48C hotter in 2023 compared with the period before the mass burning of fossil fuels ignited the climate crisis. The figure is very close to the 1.5C temperature target set by countries in Paris in 2015, although the global temperature would need to be consistently above 1.5C for the target to be considered broken.

Scientists at the EU’s Copernicus Climate Change Service (CCCS) said it was likely the 1.5C mark will be passed for the first time in the next 12 months.

So, very roughly, 0.1C pre decade for the last 150 years.

The Guardian also reproduces this nice graph:


Obviously, those still banging the denialist drum will claim 'natural variation' - but note the period from the 80s to the 90s.  Then there were several exceptional years (so many you might wonder if the term 'exceptional' is the right one).  Fast forward to 2000-2010 period - every year of that decade was as hot or hotter than the 'exceptional' years of the 80s.  

If the trend holds, it takes a decade for the exception to become the norm.  So when the Guardian points out "the global temperature would need to be consistently above 1.5C for the target to be considered broken" that will be 'achieved' by 2034.

We've got a rapidly diminishing opportunity to limit the disaster engulfing us.  But it is diminishing very, very rapidly.
