That old nebulous concept is invoked again: ‘the science’. It aims to sound like infallible authority, but that’s not what real science is. Talk of “uncharted territory” reminds us that most of Earth’s climate history also falls into that category. Made-up temperature limits based on the use of global averaging have little meaning in reality, as some politicians appear to have noticed.

Climate negotiators meeting in Dubai last month pledged to chart a course for stabilizing the climate system using good science, says Fred Pearce at Yale Environment360.
But many scientists say these promises are at best ill-defined and at worst a travesty of good science — vague and full of loopholes.
The U.N. climate conference in Dubai agreed on an action plan for two key objectives: to keep the world on track to limit global warming to 1.5 degrees C (2.7 degrees F), and to stay below this threshold by achieving net-zero greenhouse gas emissions by 2050.
Negotiators pledged that both objectives would be pursued “in keeping with the science.”
But neither of the objectives have agreed definitions that would allow a judgment on whether they have been achieved.
