So says another “scientist” (computer modeler) who’s predicting that Global Warming will make the earth significantly different by 2100.
UP TO two-fifths of the Earth will have a hotter climate by the end of the century, according to a study that predicts the effects of global warming.
The changes — which will have a devastating effect on biodiversity in areas such as the Amazon and Indonesian rainforests — will wipe out numerous animals that are unable to move to stay within their preferred climate range. They will have to evolve rapidly or die out.
Lead author John Williams, of the University of Wisconsin, said: “How do you conserve the biological diversity of these entire systems if the physical environment is changing and potentially disappearing?”
Professor Williams’ team used emissions scenarios set out by the Intergovernmental Panel on Climate Change to predict changes in temperature and precipitation.
Ugh. This guy gets loads of funding to predict the destruction of the earth. I’ve got a novel pharmacaphore and what do I get? Diddly.
Not that I’m bitter. Hey, I’ve got a great idea. My molecule will reverse global warming in 2090! I’ve got a computer projection that says it. It must be true. Give me $300,000.
As for vetting– Williams assumes that increased CO2 will increase the global temperature and that the polar cold zones will vanish, and animals will have to move north. Unless they live in the tropics, he says.
And why is that important, you ask me? Why don’t the tropics change with increased CO2? Humidity!
Water is a much better greenhouse gas than CO2, so Williams attributes the equatorial variability to water and ignores it, even though 70% of the planet is covered in water and has similar humidity variations to equatorial zones!
Isn’t that important? Isn’t the fact that global warming by CO2 is only significant in arid climates something that knocks a big hole in anthropomorphic global warming?
Let me put it this way. If the relative humidity over the oceans is about 70%, then the heat trapping of CO2 is insignificant because at that point the energy trapped by water dwarfs that of carbon dioxide. We can make a broad assumption that coastal climates and islands have humidity that’s similar to that of the ocean. We can also assume that the most drastic changes in humidity occur during winter, when the cooler air carries less water and the heat-trapping ability of CO2 is relevant. So we’re looking at a 3-6 month period where the earth absorbs enough energy in the Northern Hemisphere (and in the Southern Hemipshere during a different time period) to warm the Earth substantially and irreversibly, all thanks to CO2 amounts which have steadily risen.
So these cold, arid regions are trapping heat and then transferring the heat to the other 75% of the planet. That’s a mind-boggling amount of energy to be transferring, especially from regions that are humid, given that the heat capacity of water is nearly 2.5 times that of carbon dioxide.
If you’re having trouble with the idea, imagine that you have an egg on skillet, but you’re using a laser to heat 20% of that egg, and your goal is to cook that egg. Eventually the egg will cook, but what happens to the area where you’ve focused the laser? Yes, it’s burnt. Crispy.
The same thing should be happening to dry, arid climates. Because there has to be so much energy transferral to make an impact on the global temperature in order to make the planet hotter, the areas that are heating should be heating to gross excess, and we’re not really seeing that. We see areas that are hotter, like the Siberian winter, but the energy shift from -50 F to -45 F, while large, when diffused over a planetary surface, is minimal, especially with secondary vectors of heat loss.
So, if we go back to the egg example, if we’re cooking an egg evenly, the heat has to applied to the whole surface, not just bits and parts. And only one thing can do that– the sun. So we’re looking at either solar variability, which has been denied repeatedly, even though the sun’s activity has been noticeable, and the effect of clouds in reflecting sunlight on a universal, average scale. Less clouds, more heat, and vice versa.
