Global Warming could make Humans EXTINCT within 50 years
Kill mechanisms list
Global Warming could make the human race EXTINCT. The #1 kill mechanism is famine. See “The Long Summer” by Brian Fagan and “Collapse” by Jared Diamond. Shifting winds and warmer oceans have already created a weird moving checkerboard of drought and flood that has interfered with agriculture here and elsewhere.
The extra heat has caused heat related deaths already.
The book “Six Degrees” by Mark Lynas says: “If the global warming is 6 degrees centigrade, we humans go extinct.” The book lists several kill mechanisms, the most important being famine and methane fuel-air explosions. Other mechanisms include fire storms.
“Under a Green Sky” by Peter D. Ward, Ph.D., 2007 says H2S bubbling out of hot oceans is the final blow at 6 degrees C warming.

I thought the left supported the extinction of the human race.
So where are the supporters of this article? Where are the voices of the rabid AGW alarmists? Please! Take a shot! Step up and try to defend this garbage!
There’s nothing but silence….

“Which is the bigger business, preaching about global warming as a result of human excesses or the current manufacturing conglomerates of the world collectively producing products for human consumption? Then, who has the bigger reason to lie?”
Since the Klimate Kranks don’t produce a tanglible product to sell and are essentially leaching off the “current manufacturing conglomerates of the world,” who effectively generate the world’s wealth, one has to assume that it is the klimate kranks that have more motivation to “lie”.
What is it exactly that the “current manufacturing conglomerates of the world” are supposed to be “collectively” lieing about? The nearest I can tell the “current manufacturing conglomerates of the world” don’t speak in a common voice and don’t have a “collective” philosophy on any particular subject. The only people that I see promoting an consensus agenda are the Klimate Kranks.
RE: Denslow: (June 30, 2010 at 3:55 am ) “I thought the left supported the extinction of the human race.”
I think that finding is the purview of those guilt-complex extremists who have reverted to pure nature worship.
The article’s medley of catastrophists have one common theme: Big spending to solve the world’s problems.
More relevant than Earth going Venus might be U.S. going Greece, with unpayable debt, a collapsed bond market and printing presses in meltdown. When is Hanson due to retire?

Minor quibble based on my tender sensibilities, but could you please avoid the wording “U.S. going Greece” in the future due to a certain grammatically similar phrase? I’d appreciate it, thanks.
They are lucky there isn’t a comments secion or he would be eaten alive.
“U.S. going Greece” just means that the citizens are being [snip] by the government.
Well just maybe they might be right about the massive famines to come.
After all, it is many decades now since Scientific American magazine published a special subject issue, on energy usage and its effect on human societies.
In one paper the authors studied the relationship between energy input to a “Society”; at any and all levels of development and sophistication; from the most primitive subsistence societies; to the most industrially developed ones.
Their data showed unequivocally, that energy input equates to food production output. A remote Eskimo village adding firearms, and the energy of bullets along with snowmobiles and fossil fuels to their range of equipment; were able to increase their capture rate of seals and other food supplies for example.
No matter the level of enterprise; all over the world, energy was replaced by food at pretty much the same exchange rate. Only a couple of places sat noticeably off the common exchange rate line, in the direction of being more efficient or productive. Those two places were France and New Zealand; and both were largely due to unique weather/climate conditions in those regions. In any case; combined they hardly move the world’s food supply; simply too small a capacity in the global picture.
So the message is clear and has been for decades. If the world’s major breadbaskets do not get the energy they need; they simply will not be able to produce the food that the world needs. Of course the USA, Russia, and probably Canada figure prominently in those places that can produce food; and Canad is severely hampered by a short growing season; because of the current colder climate. A little global warming could do wonders for Canadian food productivity. Global cooling will be disastrous; and the same for Russia/Siberia.
So some of those dire famine warnings vould happen; but if they do; they will be entirely man caused by stupid energy policies; not by any climate change.

Paul Birch says “For cities in warmer climates, white roofs would beneficially mitigate the UHI effect, which can be quite unpleasant.”
…
I have thought it through. It is not zero sum. From no white to all white, there would be a net increase in albedo of order 10% (to ~90% from ~50% over the ~25% of urban area covered by roofs). Under clear skies, this would mean a reduction of ~30W/m2 absorbed at the surface, or ~7C reduction in black body temperature. Nearly all of the reflected radiation will go straight back out into space (not into air conditioners) . Only under heavy cloud would it make little or no difference. Depending on the climate, we might wish either to retain or to radiate heat at night; we could get either effect by adjusting the IR emissivity of the paint. Assuming we want to radiate as much heat as possible, we might use ordinary radiator paint, which has the right spectral properties.
—…—…
OK. Yeah. Right. Sure. (Proof that 4 positives make a negative.)
Now, what about the 80% of the country that NEEDS heating in winter (black roofs = good ???) AND ALSO needs cooling in the summer time (White roofs = good ???).
Your (foolish) “ig-Noble”-prize “winner” Energy Sec Chu thinks that we should – what? – repaint every roof top across America every spring and fall?
RE: The Total Idiot: (June 29, 2010 at 6:59 am) “I may be an absolute, and total idiot… but I can make an accurate prediction. If we make no major changes in health care, all humans currently living will be dead within 150 years.”
Can you imagine the social shock that would be created if modern medical research found a method of installing a virus-like genetic patch that would halt or reverse the adult aging process.
There would be no retirement to look forward to and no prerogatives of old age. Perhaps that might increase the mean survival age to something like 150 years due to the remaining, non-age-related causes of death.

I doubt it’s 80%, but … whatever. There are various options. The simplest is repainting. In the olden days people used to whitewash their houses several times a year, so this would be quite possible, if tedious. Or you could have two canopies extending from the ridgepole like roller blinds, one white, one black, one for summer, one for winter; just pull on the rope to deploy. Another option would be a louvred roof, like a reversible venetian blind; do it right and the louvres replace roof tiles. A higher tech solution would be a thermosensitive paint that turns white at high temperatures and dark at low temperatures.
However, even if you just use white paint, it’s the summer UHI that’s most unpleasant; for the winter you can just wear more clothes or turn the heat up a bit.
This isn’t some hairshirt man-is-evil idea; it’s an idea to make your cities more comfortable. If you’d prefer to suffer, fine.
In our part of the world there is a great pollution which cause the great threat of global warming and cause death. we people should take care of it and do more and more planting to get rid of it.
