Top Australian scientists spoke at an online conference this morning about climate change and the International Panel on Climate Change.
Professor Steven Sherwood, from the Climate Change Research Centre at the University of New South Wales says that the few things that are definitely certain should compel people to action.
“Relatively few things are certain, but these things should compel people to action. They are: (a) human activities (mainly fossil fuel burning) are increasing greenhouse gas levels, (b) increased greenhouse gas levels have a warming effect, and (c) we are observing warming at the rate calculated from this effect. None of this is contestable.”
