On the other hand, despite the overwhelming evidence that
global warming will transform the Earth's climate for centuries, with fearful consequences for human health and wellbeing (not to mention the survival

The report makes the most
of countries» commitments and a possible
global agreement, while ignoring the soaring
emissions from China and failing to recognise that the lower

The numbers are striking:
in the 1990s, as the market integration project ramped up,
global emissions were going up an average
of 1 percent a year; by the 2000s, with «emerging markets» like China now fully integrated into the world economy,
emissions growth had sped up disastrously, with the annual rate
of increase reaching 3.4 percent a year for much
of the decade.
Continuing
growth in the developing nations and economic recovery
in the industrialised countries drove the record - breaking 5.8 % increase
in global CO2
emissions to the all - time high
of 33.0 billion tonnes, even though these have not returned to pre-recession levels
in most industrialised countries.
The annualised average
growth rate

of 1.9 % for the preceding two decades back to 1990.
Then, on October 6, more than 190 countries agreed to offset much

global growth in aviation
emissions starting
in 2020.
Much
