Most of the energy of global warming is stored in the oceans and it is an enormous amount of extra energy that has ben stored between 1970 and 2003: 200,000,000,000,000,000,000,000 Joules. Which correspond to 40 billion atomic Hiroshima bombs (which is about 5 bombs per person of today earth population), or to 200 million ordinary thunderstorms, or to to 4,000 ordinary hurricane days.
Glacial melting is not only depending of human activities, it naturally suppresses the naturally occurred CO2 amplified feedback and should be expected to alter, but since 1970 the ice is rapidly melting all around the world.
If we are lucky, the industrial emissions is responsible for all this warming and melting. The worse alternative is that the 3 million year record of atmospheric carbon dioxide is going to act upon the top of what is already alarmingly high.
