I expect in a few years to be out in shirt sleeves in January. Global warming is going to be big for Canada. Invest in Canucks. Remember, you heard it here first.

No, the truth of the matter is that when the glaciers and permafrost melt, the water will trickle South, converting the barely populated nether regions of Canada in to pestilent, malarial swamps. After all, that's how the Great Lakes were formed. As for warming, you do remember that folks lived in Western Greenland in 1100AD, raised grain and cattle, and it was considerably warmer than now.

Which inhabited areas? Most of the world's population these days lives in warm or hot climates. -- Transpose mxsmanic and gmail to reach me by e-mail.

When it comes to human physiology, comparisons and relative temperatures are not terribly meaningful. It's the absolute conditions that count, because the requirements of human physiology are fixed, not relative to external conditions. Thus, 35 C is hot, even if there are places where it is 50 C. People in a temperature of 35 C will suffer equally no matter what the temperatures are elsewhere on the planet. The level of danger is the same as well. > I have worked in fabrication yards in all 3 cities and > havent much sympathy with your whining.

The effect is small in a gravitational field, thanks to convection. It is indeed a problem in zero gravity, and this has been recognized for some time. > With a fan and ambiant temperature below 37, you get cooling from the > cooler air passing by, as well as more efficient sweat evaporation sicne > you are constantly brought air that is not fully saturated with water > (aka: rtelative humidity < 100%). In high humidity or with low wind speeds, this is not sufficient to keep you cool. As the temperature and humidity rise, the wind speed necessary to completely carry off all body heat rises to impractical levels. Worse yet, since most of the cooling is evaporative, you lose water at a truly alarming rate in a hot wind, even though you may feel less sweaty. The water has to be constantly replaced, and the mere act of sweating is very tiring to the organism over time. > With ambiant temperature above 37, the fan will not push cooler air, > but will stuff push air that will help perspiration evaporate and keep > you cool. Not cool enough. You need cooling from evaporation sufficient to compensate for the air temperature above core temperature, and then even more in order to remove excess heat. That is very difficult to achieve. > And note that when it is very humid, temperatures do not often rise > above body temperature. They rise regularly far above body temperature, and even slight humidity is intolerable at high temperatures. > The really hot temperatures generally happen in > dry climates where your perspiration works fine. Not so. In Phoenix it can be 46 and humid; your perspiration does not work fine. > When it is 45 in Bagdhad, there is still more people dying from > american military presence than from heat. I'm sure the Israelis are working to beat this record. When it is 37 in Paris, there are more people dying from the heat than from any American military presence. -- Transpose mxsmanic and gmail to reach me by e-mail. |
