I came across a reference to this older item on the Skeptical Science site: Going Down the Up Escalator, Part 1. It discusses the difference between cherrypicking relatively brief intervals during which global temperatures have cooled (which is what climate-change deniers do), and looking at the consistent long-term upward trend (which is what climate scientists do). It includes this neat graph, which sums things up nicely:
See those descending blue lines in the “skeptics” version? Those represent the “cooling” that shcb likes to go on about. See that overall rising red line in the “realists” version? That’s the trend that matters.
