Indeed, the only constant in climate is change, trending one way for a while and then another—generally depending on solar and ocean temperature cycles, such as El Nino and La Nina.
The melting of the northern ice cap, for instance, comes and goes, while the southern ice cap (known as Antarctica) isn’t melting at all. Look at this photo of the American and British submarines surfaced at the North Pole in 1987.
If that situation was definitive, 24 years later there would be no ice there. Instead, we’re being warned again, by the usual government-funded climate “experts”, the tax-hungry pols and their media cronies, that the northern ice is melting. Sure is a slow melt.
UPDATE: Meanwhile, the continental USA has not warmed in a decade, summers (despite this past one in Texas) are getting cooler and winter is getting colder. And that is according to the feds.
THE TEXAS SCRIBBLER 
I am starting to believe that there indeed are some signs of the GW. Check this out:

(Via Francis). I still would like to see some incontrovertible proof of the change being anthropogenic, but it seems that there is some warming. Whether the trend will continue is another question.
The Berkeley Earth analysis is in dispute.
I don’t think there’s any question that there’s been warming overall in the past century (though the feds say not in the USA in the past decade), the question has always been the degree to which people (coal-fired electric power plants, SUVs, etc.) are the culprits—and I don’t believe anyone has yet proven they are the main ones.
