(Allen, Seaman & Delascio, 2009) Australia’s climate has warmed a lot more since 1910 by the average of 0.9’C. it has been rising dramaticllay since 1950’s.the daytime temperatures have increased by 0.8’C whereas in the night time, we experience 1.1’C more heat than the people living in 1900’s. (BOM & CSIRO, 2014). In 2004 more than 234 newspaper articles have concluded that we may have, in fact, reached the tipping point for the climate change. Walker (2006) believes that this man made climate change has caused havoc on the earth’s atmosphere and the most striking of all the components is the arctic. Farthest north is the carapace of sea ice over the Arctic Ocean. South of that is the vast ice sheet that covers Greenland. And then there is the ocean conveyor belt, which originates in a small region of the Nordic seas and carries heat and salt around the world.
