Writing in the journal Nature ahead of COP28, a team of Met Office scientists has emphasized that—surprisingly—there is currently no formally agreed way of defining the current level of global warming relevant to the Paris Agreement.
They have proposed a solution.
While the global average temperature in a particular year is well-known, this will not be suitable as an indicator of whether the “Paris 1.5″ has been breached or not, because the Paris Agreement refers to long-term warming, not individual years.
But no alternative has yet been formally agreed.
Without an agreement on what will count as breaching the Paris 1.5, there may be confusion and delay in responding.
