There are natural cycles that have been going on forever in the world. What we're doing now, with our experiment of putting a lot of carbon dioxide in the atmosphere, is introducing trends on top of those cycles. The warming that we've experienced recently in the northwest Atlantic has signals of both. We are seeing both a trend and the apex of a warm cycle on top of that trend. When the two add together, you get really rapid warming, which is what we've experienced.
The challenge going forward is that it's certainly possible that we might cool down a little bit as we go into, perhaps, a cooler phase of one of the major cycles in the North Atlantic, but that cool period will not be as cool as the cool periods in the past. Right now it looks like the climate projections, especially the newer, higher resolution climate projections, are suggesting warming rates very similar to what we've experienced over the last 15 to 30 years, which is that this region will continue to warm at about four times the global average rate.
