Once you start to look into the guts of climate change you find that just about every scientific institution in the world is conducting research on the issue.

In particular, Australia, because of its ancient geography, soil profile and distinctive weather patterns, is more adversely affected by climate variability than some other continents.

Climate change is such a huge issue that it requires strong, concerted, consistent and enduring action by governments.
