Intergovernmental Panel on Climate Change chairman Rajendra Pachauri said the general observation that climate change was bringing about an increase in extreme weather events was valid but scientists needed to provide much finer detail.
“Frankly, it is difficult to take a season or two and come up with any conclusions on those on a scientific basis,” Dr Pachauri said.
“What we can say very clearly is the aggregate impact of climate change on all these events, which are taking place at much higher frequency and intensity all over the world.
“On that there is very little doubt; the scientific evidence is very, very strong. But what happens in Queensland or what happens in Russia or for that matter the floods in the Mississippi River right now, whether there is a link between those and climate change is very difficult to establish. So I don’t think anyone can make a categorical statement on that.”
