climate sceptic argument

Via a new blog started up this summer, Fool me Once (sounds like wishful thinking ;-), proprieter Alden has graciously permitted me to embed a most excellent video he has produced on arctic sea ice. He is covering a standard denialist talking point, that arctic sea ice has/is recovering, so the concepts will not be unfamiliar to any regulars here, but the very clear trains of argument and great use of data and graphics make this well worth watching. The original posting is here. His other post from about a month ago, is similarily clear and compelling. (Warning: video starts automatically,…
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic.Objection: We all live on a thin crust that floats on a huge ball of molten iron, and at its core, the Earth's temperature is over 5000oC! It's pretty far fetched to think a few parts per million of CO2 can have a bigger effect that all that heat! Answer: Although there is nothing wrong with the statement that the Earth is truly very hot at its center (actually as hot as the surface of the sun) the notion that it is a significant source of heat at the…
This is just one of dozens of responses to common climate change denial arguments, which can all be found at How to Talk to a Climate Sceptic.Objection: The so called "Greenhouse Effect" which is the underpinning of the entire theory of anthropogenic global warming claims that greenhouse gases in the upper atmosphere absorb outgoing long wave radiation from the surface and reradiate it back, thereby warming the climate. But the upper atmosphere is colder than the lower atmosphere and the surface and the second law of thermodynamics clearly requires that heat flow from warmer areas of a system…
