Big Australian heat no passing episode

As this century progresses, the record high temperatures experienced across Australia in the past few months will no longer be dangerous departures from the norm, but a regular feature of Australian summers. This is one of the conclusions reached in a draft of the fifth assessment report of the United Nations Intergovernmental Panel on Climate Change (IPCC), which was leaked and published online last month.

We need a movement to win real action on climate change

The science that informs us about climate change is becoming more and more alarming.

The National Snow and Ice Date Center said on March 23: “On March 7, 2011, Arctic sea ice likely reached its maximum extent for the year, at 14.64 million square kilometers (5.65 million square miles).

“The maximum extent was 1.2 million square kilometers (463,000 square miles) below the 1979 to 2000 average of 15.86 million square kilometers (6.12 million square miles), and equal (within 0.1%) to 2006 for the lowest maximum extent in the satellite record.”
