Now there is still a warming trend but the moral of the story is to keep an open mind before you commit to radical action.
Meanwhile Coyote Blog has this piece of wisdom: "The GISS today makes it clear that these adjustments only affect US data and do not change any of their conclusions about worldwide data. But consider this: For all of its faults, the US has the most robust historical climate network in the world. If we have these problems, what would we find in the data from, say, China? And the US and parts of Europe are the only major parts of the world that actually have 100 years of data at rural locations. No one was measuring temperature reliably in rural China or Paraguay or the Congo in 1900. That means much of the world is relying on urban temperature measurement points that have substantial biases from urban heat."
