I read in the papers today that in 150 yrs, the Sea of Korea-Japan will get so hot that ALL the fish that we are familiar with now will become extinct in that area. According to scientists who examined the sea temperature records, the Sea temp. has been rising at an astounding rate of 0.087 degrees centigrade per yr on average. This, after 150 years, becomes 0.087 x 150 = 8.7 + 4.35 = 13.05, ie. 13.05 degrees centigrade higher than it is now, rendering the Sea inhabitable in today's standards. There must be numerous other consequences directly affected by the temperature rise.
1) More mosquitos: this would bring in tropical malaria, instead of the temperate to sub-tropical varieties we fear today.
2) increased food poisoning
3) rising soft drink prices due to the heavier work load on the coolers
...etc.
What I am most concerned about is the general efficiency of the heat engines that serve our transportation/electricity needs.
With a 13.05 degree centigrade increase, the heat engines that run our automobiles and the conventional power stations generating electricity will be running at a vastly reduced heat-to-electricity (power station) and heat-to-mechanical energy (transmotives) efficiencies. That is because the energy conversion from heat to electricity or mechanical engery is directly governed by the temperature difference between the high temp. reservoir and the low temp. environment. The 13.05 degrees will come as a blow to the engines and generators, raising the price of energy and accelerating fossil fuel consumption to make up for the reduced heat efficiency, resulting in even greater global warming. What a vicious cycle ! Any engineers or physicists out there who can tell what the actual impact will be :?
