Arbitrariness at work.
Global temperature rise could exceed “safe” levels of two degrees Celsius in some parts of the world in many of our lifetimes if greenhouse gas emissions continue to increase, two research papers published in the journal Nature warned…
“Large parts of Eurasia, North Africa and Canada could potentially experience individual five-year average temperatures that exceed the 2 degree Celsius threshold by 2030 — a timescale that is not so distant,” the paper said.
Two years ago, industrialized nations set a 2 degree Celsius warming as the maximum limit to avoid dangerous climate changes including more floods, droughts and rising seas, while some experts said a 1.5 degree limit would be safer.
And do they know that the upper limit really isn’t 1.43678o Celsius or, for that matter, 4.76803o Celsius?
