In hot water

Let us hope that our ingenious scientists succeed in finding and protecting special “climate refugiums” in which some marine life may survive global warming until humans stabilise the climate again (Richard A. Lovett, “Seeking refuge”, April 9-15). However, it is obvious that every country must co-operate with that global action for it to succeed. The latest Intergovernmental Panel on Climate Change report warns it is now or never for climate action and it must become central in every society. Australia especially must show how we can do that in our imminent federal election.
