That's what I though as well, but after I went investigating, I found out that actually, Antarctic sea ice levels were at record highs, which basically means that glaciers were melting more than usual (and shedding huge pieces of ice into the sea) - apparently because of winds bringing more hot air from northern (hotter) regions.
That's not against the rules per se, but there have been lots of sock puppets used on global warming topics.
Rather than acknowledge the uncertainty, climate scientists like Michael Mann appear to be trying to create the illusion that their climate models are more accurate than they really are. For example here is a slide from a 2012 presentation he gave: https://climateaudit.files.wordpress.com/2013/03/hansen1988-...
Notice that he simply lops off the temperatures after 2005 because they don't neatly fit the curve! It's bizarre to see. It's this sort of behaviour from climate scientists that initially piqued my skepticism.
When I first started looking into the CAGW debate with any scrutiny I honestly believed I would find skeptics using fake data pumped out by right-wing think tanks. Instead I found what appears to be fake data pumped out by government agencies. Go figure.
Don't get me wrong - I don't think these individuals are pumping out fake data on purpose. For example, they may believe in global warming so strongly that when the data doesn't show the expected warming they a) wonder why the data isn't showing more warming, b) come up with a plausible sounding reason as to why the data isn't showing more warming, then they c) 'fix' the data via a series of 'adjustments'. Also known as confirmation bias and group-think.
It turns out that a significant portion of the recorded warming is due to these data adjustments. We're talking as much as 20% or more, depending on the data-set. That should also raise some red flags.
Been meaning to get to a better reply. As to sources, in the case of temperature adjustments, it's all there in the mainstream data-sets. I could point you to some skeptical sites that are picking the data apart if you like. There are some newspaper articles on this, all right wing outlets of course. It seems both sides only print the stuff that caters to their audience.
For example, relating specifically to the article, I could simply point out that the REGIONAL Western Antarctic melting is most certainly due to volcanic activity and that Antarctic ice levels were at all time record highs for much of last year. The article doesn't even mention the recent record-breaking ice levels?! Doesn't that seem strange? It seems any information that doesn't confirm the prevailing view is neatly filtered out. It's bizarre to watch, but strangely fascinating.
I could show you that the lynch-pin of the CAGW argument is simply assumed in the climate models. It is highly uncertain, unproven, and is not born out by observation. It's easy to do and relies entirely on mainstream climate science.
And for all this I get called a "climate denier", a term that is meant to associate me with "holocaust deniers". From your article: "DH0. Name-calling. - This is the lowest form of disagreement, and probably also the most common."
Yes, it is the most common response I get from CAGW advocates. Ironic, isn't it?
