Okay, the liquid water is beneath 1.5 km of solid ice at the South Pole, but it is there!
It’s also incredibly salty [one reason why it isn’t frozen], but its discovery opens up huge new areas of research because it means that Mars really was much wetter in the past. I’m no geologist or climatologist, but I can’t help wondering what happened to Mars to turn it into the barren rock it is now. If there’s any chance that our own Earth can go the same way, we need to know.
Sitting here with the aircon turned on, and a hot north wind blowing outside, it’s hard not to be afraid, especially after seeing this graph:
The graph charts temperatures over the last 100 years – from 1910 to 2010. Not surprisingly, blue represents years of below average cold and red represents years of above average heat. And no, it wasn’t your imagination – summers really have been getting hotter.
My growing up years [1950s to 1970s] were mild. We did get the odd hot day in Melbourne. We even experienced the odd heatwave, but they were unusual events. I know, because we did not even own a fan back then! Now, I can’t imagine living without an air-conditioner.
Unfortunately, heat is not the only thing that’s changed. Nor will it be the only thing that gets worse. I highly recommend reading the complete report from the Climate Council:
You can also read an abbreviated, ‘highlights of’ article about the report here:
Now think about these facts – every year for the last three years has been the hottest on record. That means since we’ve been measuring and recording temperature.
According to the Climate Change deniers and skeptics, what we’re experiencing is just another ‘cycle’ in the earth’s climate history. We’ve had ice ages, now we’re having a period of heat. The one thing they’re not ‘having’ is that this period of heat might be caused by humans rather than natural fluctuations.
So let’s take that perspective to its natural conclusion: the world may be getting hotter and climate may be getting more extreme, but it’s not our fault so there’s nothing we can do about it except ‘suck it up’ [and hope we all survive].
To me, that is the most terrifying, defeatist outlook possible. Yes, it does allow for ‘business as usual’, but only because disaster is inevitable so we may as well make money while we can.
By contrast, almost all of the actual climate change scientists say that this distopian outlook is not inevitable. It will take a lot of work, and things will get worse before they get better, but there’s a good chance that we’ll survive…if we clean up the mess we’ve made.
As one of the canaries in the coal mine, I much prefer the optimistic outlook, don’t you?
But why do I imply that Australians are canaries in the coal mine? Isn’t that fate reserved for the island nations of the Pacific?
Um, no, actually. Australia has quite a delicate climate. Yes, I know, how can deserts and bushfires be delicate? What I mean is that we already experience extremes thanks to our geography which means that climate change will have less work to do to make extreme turn into unbearable.
But it is the Australia inhabited by this generation’s grandchildren, 2090, where the heat will really be on, if greenhouse gas emissions worldwide fail to meet current reduction targets.
By that year the report predicts Darwin will have a staggering 265 days each year above 35C.
That quote was taken from the news.com.au article, but the data comes from the Climate Council report [linked above].
Melbourne won’t fare so badly in terms of temperature, but we’ll have other worries – such as increased droughts and a great many more bushfires. If we continue with business as usual, life will be close to unbearable for our children and their children. This is not some dystopian, science fiction plot line I’ve come up with to give you all a good scare. This is real, my friends, and becoming harder to fix with every day we procrastinate.
Back in 2009, eight years ago now, Malcolm Turnbull lost the leadership of the Liberal Party because he supported the Rudd, Labor government, in its attempts to get a Carbon Pollution Reduction Scheme up and running. Many Australians honoured Turnbull for that, seeing him as a politician of integrity. Many Australians supported his return to the leadship of the Liberal party for the same reason. I know I did. 😦
But where is Turnbull now? Shackled to the idiology of the ultra Right, that’s where. These Conservatives do not believe in human induced climate change. As a result, they fight tooth and nail to keep Australia from shifting to a low or neutral carbon economy [read renewables instead of coal]. If Turnbull wants to stay in power, he has to appease these deniers and skeptics.
Well guess what? Turnbull has been appeasing these deniers and skeptics. The latest ‘clean’ coal proposals are the greatest betrayal possible because Turnbull must know that the holy grail of clean coal will never be achieved. Even with the most stringest technologies currently available [which would make electricity from coal more expensive not less], coal fired power plants would still produce more emissions than gas fired power plants. Yes, gas. Not solar, not wind, not wave or geothermal, but gas.
I no longer believe that Malcolm Turnbull is a man of integrity. He has what he wanted all along – the Prime Ministership – and he’ll betray everything he believes in to keep it. Thanks, Malcolm. I hope your stay at Kirribilli House is short.
