THE HEAT IS ON

In the years ahead, climate change will have a significant impact on every aspect of the daily lives of all human beings -- possibly greater even than war. Shifting precipitation patterns and ocean currents could change where and how food crops grow. If icecaps melt and low-lying areas are flooded, as is predicted, entire populations could be forced to move to higher ground. The tsunami of 2004 and Hurricane Katrina, in 2005, provided vivid examples of what large-scale climactic catastrophes entail.

This is a historic moment. Australia's Parliament has put the nation's first carbon price into law. With this vote, the world has turned a pivotal corner in the collective effort to solve the climate crisis. This success is the result of the tireless work of an unprecedented coalition that came together to support the legislation, the leadership of Prime Minister Gillard, and the courage of legislators to take a vote that helps to safeguard the future of all Australians.

I have spent enough time in Australia to know that their spirit of independence as a people cannot be underestimated. As the world's leading coal exporter, there's no doubt that opposition to this legislation was fierce. But through determination and commitment, the voice of the people of Australia has rung out loud and clear.

Today, we celebrate. Tomorrow, we do everything we can to ensure that this legislation is successful.

Unusual winter weather in the atmosphere high above the Earth's surface caused an "unprecedented" loss of protective ozone over the Arctic this year, scientists say.

The ozone layer in the stratosphere, located about 15 to 35 kilometres above the Earth's surface, protects the Earth from the sun's ultraviolet rays and harmful effects such as skin cancer. While an ozone hole has formed in the stratosphere over the Antarctic each spring since the mid 1980s, a paper published in Nature on Sunday marks the first time scientists have reported a comparable loss over the Arctic.
