"Climate change sceptics and fossil fuel companies that have lobbied
against action on greenhouse gas emissions have squandered the world's
chance to avoid dangerous global warming, a key adviser to the
government has said.
"Professor Bob Watson, chief scientist at the Department for
Environment and Rural Affairs, said a decade of inaction on climate
change meant it was now virtually impossible to limit global
temperature rise to 2C. He said the delay meant the world would now do
well to stabilise warming between 3C and 4C.
Watson backed controversial calls for research into geoengineering
Such an effort could divert attention and funds from efforts to cut
techniques, such as blocking the sun, as a way to head off dangerous
temperature rise – one of the most senior figures so far to do so. "We
should at least be looking at it. I would see what the theoretical
models say, and ask ourselves the question: how can we do medium-sized
experiments in the field?"
carbon and switch to cleaner technology, he said. "I think it should
be a real international effort, so it isn't just the UK funding it."
