SHARKS are expected to be a regular feature at beaches around Australia as climate change takes a grip on what is expected to be the hottest summer on record.

A 4.1m tiger shark was spotted in Queensland as the state’s biggest ever shark recently.

There have been more shark attacks in the past three years in the country than ever before.

Climate control also poses problems to agriculture making the free trade of food crucial if the world hunger crisis is to be effectively tackled according to Agriculture Minister Tony Burke says.

Mr Burke said productivity improvements in farming would not deal with climate-change-driven extreme weather events that would wipe out entire crops.

”Subsistence [farming] doesn’t get you there in food security if you have the risk of entire crops being wiped out through more major weather events,” Mr Burke told The Age recently. ”Allowing food to move is the essential element of food security.”
