And now it’s global COOLING! Record return of Arctic ice cap as it grows by 60% in a year
- Almost a million more square miles of ocean covered with ice than in 2012
- BBC reported in 2007 global warming would leave Arctic ice-free in summer by 2013
- Publication of UN climate change report suggesting global warming caused by humans pushed back to later this month
They say a picture is worth a thousand words, this one really exemplifies the case:
I babble about global warming from time to time as a ‘skeptic‘, but it seems to me that there is increasing hard data that show things are failing to perform as expected. Given that models are well-known to be nearly worthless (largely because chaos theory practically requires them to be incapable of functioning when we can’t accurately measure the starting conditions or adequately quantify all the changing variables), it is quite amazing to me how quickly people have jumped on the end-of-the-world band wagon (though I babble about the apocalypse all the time so I shouldn’t be the pot calling the kettle black). Models are great in an academic sense and certain models can identify broad trends that occur much of the time, but models tend to be nearly worthless at specifics. Sure, we can posit that in the long run the increase in CO2 will cause a higher level of global temps, perhaps even several degrees, but that is over the course of thousands of years. In the shorter term (centuries) other weather oscillations might totally cancel out (or reverse!) the long-term trend, for periods of decades or longer.
Don’t forget: the long-term (next 10,000 years) we are slated to go back to our ‘normal’ climate of an ice age. That is almost a certainty since that cycle has been well documented to be based on solar system-wide cycles, so we might soon wish we has ‘too much’ CO2 in our atmosphere. We certainly don’t want to sequester any CO2 too well!
