Should AGW sceptics understand what they are talking about? Of course! Let’s have a look at the critical view of Alan Carlin expressed in a recent post (Dec.30,2016): “Why Climate Alarmists Have Missed the Big Picture”. He claims that “There is evidence that very minor changes in the incidence of sunlight on Earth can and have resulted in plunging Earth and all its living cargo into new ice ages”. It is not the sun but the oceans, and Alan Carlin, as a sceptic for many years, should know it.
Back in 2009 Alan Carlin, an economist and senior analyst at the EPA (US Environmental Protection Agency), became a sudden celebrity with the surfacing of a few e-mail messages that seemed to show that his contrarian views on global warming had been suppressed by his superiors (NYT). It seems he did not use his new influence well, but ignored further on the relevance of the oceans in climate matters, as outlined HERE, HERE & HERE.
However, Alan Carlin rightly warns about the major climatic risk, namely “that Earth will plunge into a new ice age, with global temperatures ultimately reaching perhaps 6 to 8°C below current temperatures.” Presumably lower annual temperature of just 1-2°C, are enough for a serious threat, and the oceans are so cold that it can happen within a few months or years.
