some will tell you that the hot weather in Australia is no big deal. but this article points out that earlier heat events in Australia in the 20th century did not stay that hot for this long.
we have a word: "unprecedented"- it means "this never happened before." Whenever you see that in terms of hot weather, it is another piece of evidence. the evidence piles up. One hot day does not prove global warming, but a century of increasing temperatures across a planet do.

The surface of the Earth, as measured by global mean temperature, has warmed by about one degree Celsius during the past hundred years, and the decade from 2001 to 2010 has been the warmest we have recorded.
This warming has been strongly attributed to increasing greenhouse gases from human activities. While there are a number of influences on the climate system, such as changing solar radiation and changing atmospheric aerosols, it is very clear that warming has been dominated by increased carbon dioxide levels.
Future warming of the climate due to greenhouse gas emissions will very likely lead to further increases in the frequency of unusually hot days and nights and continued declines in unusually cold days and nights.
These changes will result in weather events which are increasingly beyond our prior experiences.
Of course, these are just actual climate scientists. Some denialist will show up to show fake graphs from an anonymous blog citing other anonymous bloggers and non-science pseudonymous bloggers funded by fossil fuel lobbyists. After all, if you can rely on lobbyists you can dismiss 100+ years of actual science.
Still doesn't make it global warming Chris.
No Larry,
A weather event is just a weather event!
"For example, the report cites “strong evidence†that manmade global warming has “roughly doubled†the probability of extreme heat events, such as the record hot summer of 2011 in Oklahoma and Texas. It also notes that sea level rise is exacerbating storm surge problems along the East and Gulf Coasts, and that sea level rise played a role in exercerbating the impacts of Hurricane Sandy."
Also,
"First and foremost, the report strongly states that human activities — mainly the burning of fossil fuels for energy, which emits heat-trapping greenhouse gases — are changing the climate in ways that are already harming the U.S."
The science is clear.
For the policy to deal with that science we can be honest and take responsibility, or we can be dishonest and deny the science.
The choices we make say a lot about us.
