At its annual gathering in Canberra today, the Federation of Australian Science and Technological Societies will tell politicians that the campaign being run against scientific evidence of man-made climate change ''is undermining the national building work of all scientists''.

Its own campaign, respect the science, will seek to broaden the understanding of how science works.

"The valuable and credible work of all scientists is under attack as a result of a noisy misinformation campaign by climate denialists. It's in the nation's interests that our political leaders now lead the community forward on this critical issue," the federation's chief executive officer, Anna-Maria Arabia, said.

The New Zealand Prime Minister, John Key, will address a joint sitting of Parliament today. Mr Key is a conservative but his government has introduced an emissions trading scheme.

The Prime Minister, Julia Gillard, will be hoping for some boost from Mr Key's visit as her government struggles over plans to put a price on carbon.

Yesterday, the Climate Change Minister, Greg Combet, held further talks with the Greens as the two parties strive to reach agreement on a starting price for carbon and the levels of industry compensation.

The independent MP, Rob Oakeshott told the Ten Network's Meet the Press that consideration must be given to the already high-cost of living.
