As nations approach the critical 1.5 degrees Celsius threshold outlined in the Paris climate agreement, scientists are racing to establish a standardized method for tracking global warming. Currently, there is a lack of consensus on how to measure warming effectively, which complicates early warnings about climate change impacts. An expert team from the World Meteorological Organization (WMO) is working on this issue, with recent findings indicating that current warming stands between 1.34 and 1.41 degrees above preindustrial levels, aiming to provide reliable metrics for future assessments.
"The world can't seem to agree on when the planet will exceed a key temperature threshold in the Paris climate agreement...there is no official metric for determining when the world has crossed that line into increasingly catastrophic impacts."
"The World Meteorological Organization first convened the team of around 10 experts last summer to look at the different methodologies and devise a more accurate way to measure current warming."
"Some of their preliminary findings are detailed in the WMO's latest State of Climate report, which estimates that current global warming is somewhere between 1.34 degrees and 1.41 degrees compared with the 1850-1900 average."
