December 2002 Canada
Canada has ratified the Kyoto protocol, paving the way for Russia
to also ratify and for the agreement to finally come into force.
This would give real meaning to the protocol, despite the absence
of the US and Australia.
December 2002 Scratched

year in the UK for 350 years and the 2nd warmest globally since

governments to commit to GHG reduction targets. They cite their
greater need for economic advancement as justification.

Levy (CCL). The CCL is designed to drive up energy efficiency and
reduce GHG emissions, but some business leaders think it is too

run on compressed air alone. The car will have almost zero GHG emissions
and be very cheap to run. It is said to have a top speed of 65 mph.
September 2002 By

warming will continue even if GHG emissions are cut, albeit at a
slower rate. Their model helps to demonstrate man's forcing of climate
in the last 50 years.

reported that many Southern Ocean invertebrate species may become
extinct if warming predictions for the region are correct.

Kyoto target of 55 per cent of global greenhouse gas emissions is

on Tony Blair and other leaders at the Johannesburg World Summit

rice paddies can be lowered by increasing rice yields. It seems
that, where yields are low, more carbon is available for methanogenesis.
