Global warming and climate change are our biggest threats.
These are as few comments form a recent article. Imagine our climate if it was 6 degrees hotter. 43 degree days could be the norm in summer in a few decades.
"We now know that 19 of the world's 20 hottest years have occurred since 1980 - the three hottest have all occurred since 1998. We know that icecaps are melting, coral reefs are being bleached, floods are more frequent and glaciers are disappearing, and that we can expect more powerful hurricanes, drier land, more frequent fires and the extinction of a growing number of species.
This week, a report by the Australian National University, commissioned by the Federal Government, found that by 2100 temperatures could increase by almost 6 degrees - much more than originally estimated."
