Eminent theoretical physicist and climate sceptic Freeman Dyson
interviewed by emailin last Friday's Independent by their
science editor Steve Connor.
Dyson is famous for his work in the field of quantum
electrodynamics, in which he made a
major advance in 1948. Now retired, he is a member of the
academic advisory board of the climate sceptic thinktank the Global Warming Policy
In an occasionally testy email exchange, The Independent sought
to tease out Dyson's position on climate change. We took a look at
what he said.
"the computer models are very good at
solving the equations of fluid dynamics but very bad at describing
the real world. The real world is full of things like clouds and
vegetation and soil and dust which the models describe very
This statement implies that computer models do not take into
account the impact of clouds, vegetation, soil and dust on
temperature trends. This is
Climate models are mathematical representations of the
interactions between the atmosphere, oceans, land, ice and sun.
This is a complex task, which means that there are limitations to
the certainty that scientists give to model predictions. These
uncertainties are factored into the predictions made
by the IPCC, and are made obvious in their reports.
