One of the recent posts on Watts Up With That (WUWT) is by Joseph D’Aleo, CCM, Weatherbell Analytics and is called global warming theory has failed all tests so alarmists return to the 97% consensus hoax. I’ve written enough about the 97% consensus issue, so won’t say anymore here other than calling it a hoax seems somewhat unjustified.
Basically, the WUWT post lists 25 failures of global warming theory. I had considered trying to rebut some (or all) of these statements, but there’s a problem. Virtually none of the 25 failures listed in the post includes any kind of reference or citation. I’ve been reading quite extensively on the subject, but I can’t work out where the information is coming from. It’s quite possible that there are publications that have indeed made the predictions that this post now claims have failed, but that may not necessarily be relevant. I don’t even know if the supposed claims about global warming were made in peer-reviewed papers, media reports, or government reports. Essentially, a post like that on WUWT has no real value since you can’t easily confirm or deny the claims being made.
What the WUWT post does seem to do is conflate global warming with climate change (the list includes failures of the models, climategate, the survival of polar bears, levels of rainfall,…). It’s certainly my view that we should be putting more effort into distinguishing between global warming and climate change. The evidence for global warming is extremely strong (satellite measurements, ocean heat content, arctic ice volume, global surface temperature), while the evidence for climate change is less certain. Using that the climate hasn’t changed as supposedly suggested isn’t enough to indicate that global warming theory has failed. It might suggest that our understanding of climate change is flawed, but even that isn’t certain given that I can’t really identify where the claims refuted in the WUWT post were made.
I realise that I haven’t provided citations and references in the post, so am – to a certain extent – guilty of the same deficiency as the author of the WUWT post. If anyone would like to know more about the evidence for global warming, I’m happy to provide it through the comments.
