Why we should forget about the 1.5C global heating target

The goal of 1.5C by 2030 is arbitrary and now unachievable – yet working to prevent every 0.1C rise can still give us hope

Bill McGuire is professor emeritus of geophysical and climate hazards at UCL

Keeping the global average temperature rise (since pre-industrial times) below 1.5C is widely regarded as critical if we are to sidestep dangerous, all-pervasive climate change.

To have a fair chance of keeping this side of 1.5C, emissions have to fall by 45% in little more than 90 months, and I am on record as saying that this is practically impossible. But it’s worse than that. It is perfectly feasible that we will crash through the 1.5C guardrail even earlier.

yet working to prevent every 0.1C rise can still give us hope

Hope of what?  That we've been working against a natural cycle?  The simple fact of the matter is that on a geologic time scale - which is the only time scale that matters when considering global attributes like climate - the global mean temperature is still below average.  Accordingly, the global mean temperature should be rising, and it is a profoundly anti-ecological position to take to claim that we should be opposing that rise.

What we should be doing is adjusting our global, aggregate, behaviors to take into account the likely effects of the rising global mean temperature, such as disincentivizing the construction of unprotected residential structures in low-lying and coastal areas.
