Another part of this story is the failure of media to deal with
the idea of total emissions versus per capita emissions.
Not exact matches
Hence, we get a strong
idea of total methane
emissions over all source sectors but get much less information about individual sectors.
The
idea of a «carbon budget» that ties an amount
of future warming to a
total amount
of CO2
emissions is based on a strong relationship between cumulative
emissions and temperatures in climate models.
To simplify the
idea — if 95 %
of atmospheric CO2 is natural but we do not know how much overall the natural
emissions amounts change over time, but we do know they change, it is easy to see that a 10 % change in natural
emissions would have potentially great change to
total CO2.
