On August 18th 2014, Facebook told TIME that 2.4 million Ice bucket challenges had taken place – a figure which had more than doubled from 1.2 million in 5 days! When I sent a friend a picture of me doing the IBC they commented that it was a huge waste of water (sometimes you can’t do right for doing wrong). But, speaking globally, is this a significant waste of our fresh water resource?
My friend and colleague Erik Dalhuijsen passed along a link to this website in which a number of scientists express their fears about climate change. It’s quite a sobering read but there is an element of hope attached for each of the stories of fear. In particular I liked what Will Steffen, an Earth System Scientist at the University of Florida, University of Missouri and Australian National University had to say:
The thing people don’t realise, is getting emissions down is not only feasible but economically promising and will actually lead to a better life. The narrative needs to change, it’s not all doom and gloom. Yes, it will be another massive transformation in human history, but it will lead to a cleaner environment, to more jobs, and an easier lifestyle.
In order to make any substantial impact on the CO2 emissions with CCS (Carbon Capture and Storage) we need to be injecting about 3.5 billion tonnes per year (Pacala & Socolow, 2004) into saline aquifers and depleted hydrocarbon reservoirs. Based on the information available from this MIT Database we are currently achieving less than 0.1% of this volume.
