'We've nothing to worry about – climate change is just a
myth'. I'm quite sure you have heard that said before. But is it? Climate change scepticism is nothing new. Most aspects have been contested both in the media and in academia. You might like to know that sea
level rise doesn't escape the net either. To gain a more reliable view we should
take a look at the bigger picture rather than just cherry picking particular
studies that might back-up our argument or by looking at small time scales
without thinking about how these might appear differently if we examined more
data.
Luckily, scepticism is not such a bad thing. As F. Scott Fitzgerald’s quote ‘Conflict itself has
a value beyond victory and defeat’ suggests, something can be gained from
opposing arguments and debate. Jerry Mitrovica, Professor of Geophysics at Harvard,
thinks the value in his field is that sceptics ‘force us to look at sea level
with a renewed interest and insight that will help us go into the future’. His
talk given at an interdisciplinary climate change meeting in 2011 can be watched below.
While I would encourage you to watch as
it was informative and relatively easy to understand, I will try to sum
up the key arguments of sceptics which the talk is structured around.
- 2 mm/year is not anomalous – sea level has been rising at this rate for thousands of years.
- Sea level change varies dramatically from place to place – melting ice sheets cannot be the culprit.
- Even so, 2 mm/year is small and stable.
I don’t want to give the game away
straight away (in case you want to watch the talk) so my next post in a few
days time will explore how Mitrovica challenges the claims of sceptics and where
this leaves societies at risk.
Did you know that some American states have considered banning the use of terms such as sea-level rise, e.g. north Carolina!

This seems crazy! Thanks for drawing my attention to this blog - apparently Virginia and Texas have attempted similar things. I certainly need to look at the issue in more detail and it also fits well with my recent posts regarding America and its politics.
