A ''very, very specific'' climate conference concerning
two layers of the earth's atmosphere concluded yesterday in
The Stratosphere-troposphere Processes and their Role in
Climate (SPARC) general assembly brought together about 280
international and about 20 national scientists.
Sparc co-chairman Dr Greg Bodeker, who is based in Alexandra,
said themes of the conference included the many different
components of the climate system, which cannot be looked at
''in isolation'', and the importance of the link between the
stratosphere and troposphere in climate.
''It just becomes obvious that you can't make long-term
predictions about climate change without taking into account
the stratosphere,'' Dr Bodeker said.
He said climate scientists used to ignore the stratosphere,
which is higher, and only include the troposphere in their
models but it was ''increasingly apparent'' they needed to be
thought of as a ''coupled system''.
The conference included poster viewings and lectures on
topics including the link between aviation and climate,
stratosphere and ocean interactions, the hiatus of global
warming and why sea ice in the Arctic is decreasing whereas
it is increasing in the Antarctic.
A particularly interesting talk, Mr Bodeker said, came from a
Google representative who discussed a project the company was
undertaking called Project Loon.
It began in 2013 in New Zealand with an experimental pilot
programme and aims to provide internet connectivity to remote
areas using a network of balloons floating in the
