I just checked - they all died last summer.

As the theory goes, rising carbon dioxide levels from human activity causes some temperature rise which causes more water to evaporate. Because water vapour is the dominant greenhouse gas, the additional water vapour absorbs even more energy, so global temperatures rise even, more causing still more water to evaporate and so on in an amplifying spiral. In this way the roughly half degree direct impact from doubling carbon dioxide is claimed to be amplified to three degrees or more. An interesting theory, but now consider the following scenario; We know the earth rotates about an axis tilted about 23 degrees relative to the sun. This is what causes the seasons and what sets the Tropics of Cancer and Capricorn. Imagine a location on the Tropic of Capricorn (23 degrees south) - say Mackay in Queensland. In summer the sun is directly overhead - average solar input of around 310 watts/sq meter. In winter the sun is at maximum elevation 44 degrees - average solar input of around 220 watts/sq meter. That is a difference summer to winter of about 90 watts/sq meter which, according to Stefan's law, without any feedbacks would give a temperature difference summer to winter of about 16 degrees. The amount of positive or amplifying feedback claimed by the IPCC would inflate that about 6 times to more than 90 degrees C, extinguishing all life in Mackay. http://jennifermarohasy.com/blog/ Warmest Regards Bonzo -- You know of course that in most parts of the world, pain is a second language, people understand it better than words because you can get right to the point. - Capt Real Estate |
