Be afraid. Be very afraid
Earlier this week, I read an article in Scientific American that had an ominous warning ‘global warming is close to becoming irreversible’. In typical cautionary climate-speak there’s a hope stated that “we can cap temperature rise to two degrees”. This is followed by a more subtle message, “we are on the cusp of some big changes”.
‘On the cusp of changes’ is an understatement. There are a half-dozen possible tipping points, crossing any of which gets us into scary unchartered territory. Ocean acidity and coral die-off; drying the Amazon rainforest; run away growing fossil fuel use; loss of ice sheets; large scale melting of permafrost: and the biggest tipping point of all – our amazing inability to come anywhere near an agreement limiting global GHG emissions and warming.
The article argues that unless we seriously curb the rate of growth of GHG emissions within the next 10 years, we will cross tipping points that lead to significant and irreversible global warming. And yet, all that was agreed at COP17 in Durban last year is for countries to reach an agreement by 2015 for action that will not start until 2020. Too little too late, according to the science.
The world will likely only see 450 ppm CO2 concentrations from our rear-view mirror as we hurtle down the express lane to at least 550 ppm CO2 and a 5 degree warming. What the article doesn’t say is that we will need to figure out how to geo-engineer some sort of amelioration. Good luck with that. We can’t agree on the much easier aspects of limiting GHG emissions; how will we ever agree on something as complicated as managing the planet’s climate?



The complexity of climate change issue is a challenge for most mainstream media, which increasingly seek the shortest possible sound bite to interest an audience with a very limited attention span. Yet a recent example illustrates the importance of looking past the headlines to understand the importance and true meaning of scientific announcements. The article featured the optimistic headline: “
Henry Ford once famously said that if he had asked his customers what they wanted they would have asked him for a faster horse. If he had listened to his customers, the Ford Motor Company may never have existed, or would be called the Ford Faster Horse Company. The automobile became what is called a “disruptive innovation” meaning that it radically displaced the incumbent technology (the horse and carriage) by not listening to the demands of mainstream consumers, but trying to uncover their real needs.
