Last year around this time, much of Australia was suffering through a record heat wave that had many worrying that global warming had ushered in a new unyielding era of heat and drought. Maybe so....
Australia is shattering the records set just last year, according to the London Independent, which points out that Australians emit more carbon per person than even the United States....More than any nation in the world.
The nation is in the midst of a 12-year drought that has severely cut into its wheat crops at times, and the heat is reaching extremes (try 114 degrees F in Adelaide) that more than 20 have died in the latest heat wave.
We typically look to the Arctic to look for early signs of global warming. But excessive summer heat, and drier more persistent droughts are harbingers of things to come as well.
