Harold Ambler comments on An Open Letter to Climate Change Denialists « Legal Planet: Environmental Law and Policy

10. We are always one volcanic eruption away from sudden, problematic cooling. That is among the reasons that NASA has spent so much money researching vulcanism during past solar minima (the other reason being to obfuscate the fact that the Sun largely drives Earth’s climate). Warmth has historically been good for Earth’s people. One reason that we are all here arguing about this today is that we live at what most consider to be the tail end of an interglacial. The Dark Ages were to a great degree begun by a single volcanic eruption in 535: Krakatoa.

11. Farmers in Canada and the Northern Plains of the USA are struggling due to the June frosts this year. Ice wine has been produced in Brazil for the first time this year.

12. The coldest temperature ever recorded in the state of Maine — -50 degrees Fahrenheit — was measured this year. Ask your friends in New England what winter has been like for the past two years.

13. The changeover of the Pacific Decadal Oscillation to its negative phase two years ago has ushered in a new climate regime. When the Atlantic Multidecadal Oscillation switches to its cool negative phase as well (anticipated in 2015, but it has flirted with negative values already this year), people will LAUGH about the time when so many feared global warming.
