The planet went for 10,000 years with a CO2 level of about 260 ppm in the atmosphere. Since the industrial revolution, in less than 300 years the CO2 level has gone to about 425 ppm - an increase of over 60%. In tha same time, the oceans have warmed by just under one degree C - an insignificant change, right? Wrong - it is a change in stored heat energy almost beyond human comprehension. The Tsar Bomba is the largest nuclear device ever detonated on Earth. The energy released was 3,300 times more powerful than the bomb that devastated Hiroshima. To raise the temperature of the oceans by another 1 degree C, we would need the equivalent of 26,300 Tsar Bombas — assuming perfect transmission of heat energy, which entropy prevents. Global warming is the Second Law of Thermodynamics in operation. Climate change is the First Law. Get used to it.
