Dr. James McCarthy testified at a Senate hearing on Wednesday that the temperature deep in the ocean is increasing. This is very important. Water is very difficult to warm up and the amount of water in the world’s oceans is very large. So, it would take a very great deal of energy to noticeably warm the oceans. But, that is just what is happening.
Dr. McCarthy’s testimony (as well as the rest of the day’s hearing) can be seen here.
I wonder how the global warming deniers will try to spin this one.
