With just philosophy, we can have a great argument on the meaning of this curve. Does the past out-weigh the present? I'm staying out of that, but the ice volume is doing well. The volume is the best indicator of whether the world is getting colder, but this chart is a totally made-up thing. There is no satellite radar that can determine the thickness of the ice for a volume calculation. They just integrate the temperatures to get the product.
When the summer comes, we'll get lots of news on how the Greenland ice sheet is melting. Fine, let the warmies have their fun.
pps. nooa has not come out with the world temps. If they don't like it, it takes a week to 'work out the kinks'. :)
