It is so easy for any discussion of climate change to get lost in numbers so we thought we might take the time to put some of the numbers that get thrown about into a human perspective.
16,000,000,000,000 watts This is the amount of fossil fuel powered energy humans consume each year. That’s about a third of the energy that is released each year by plate tectonics, the geological process that moves continents around the globe and creates mountains!
28,000,000,000 tonnes This is the amount of CO2 that is released globally each year. That’s enough to cover the entire surface of Australia to a depth of 2 metres!
300,000,000,000,000 watts This is the amount that the world’s oceans are heating by each year due to human induced climate change. That’s the same heat as would be released by detonating 5 Hiroshima sized nuclear bombs every second of every day for an entire year.
$8 The estimated cost per week per household that a new report from the University of Melbourne says would be required to transform the entire Australian electricity production system to renewable energy by 2020. That’s two to three cups of coffee per household per week or a mere 3 percent of Australia’s GDP.
40 percent This is the emission reduction target that the ACT legislative assembly’s own inquiry suggested could be achieved in the ACT at zero net cost. In the ACT we can’t remodel the Australian electricity generation system by ourselves, but we can still be leaders. We can show the rest of Australia that serious action on climate change is possible. We can light the way for the rest of Australia to follow.
Climate change is a real and serious problem. But real and serious solutions do exist. Working together we can solve our climate crisis. But the time to act is now.
The ACT cabinet is on the very cusp of deciding what target it will introduce into the Legislative Assembly. We need to write, phone, fax and email them to tell them that any target less than 40 percent is aiming too low. To make this easier and to help you engage with your elected representatives we have created a page that provides instructions on contacting your representatives and tips on letter writing.
And pens aren’t the only weapon you can pick up to fight climate change. After the unfortunate illness of our ‘knit against climate change’ organiser put all things woollen on the back-burner for a while, they are starting to gain momentum again. Two knit-ins have been held at Tilley’s and some real progress is being made. To get involved join our knitting Google group here.
Finally, the statistics in this post were all taken from the new Zero Carbon Australia report. It makes fascinating reading if you have the time.
