"Many officials and climate activists claim we have only 12 years to act on global warming.
Where does this figure come from?
A 2018 Special Report by the Intergovernmental Panel on Climate Change (IPCC).
The second sentence of that document reads, "Global warming is likely to reach 1.5 degrees C between 2030 and 2052 if it continues to increase at the current rate."
The 12-year figure comes from subtracting the year of the report, 2018, from the earliest possible date of 1.5 degrees C warming, 2030.
The problem is that this was a statement about the past, dressed up to suggest that it's about the future.

It's not about what will happen; it's extrapolating from what has already happened.
Actual temperatures in 2030 will depend on whether warming speeds up or slows down, and also on whether the year is warmer or colder than the long-term trend.
Why the 22-year range?...Read all and watch the video.
