The condition is still long. However, very foolish if we ignore global warming. The temperature of planet Earth continues to show upward trend. If the increase is too much, most of the human population spread must now move their homes or rely on air conditioning to avoid death.
"Currently, we have air conditioning for comfort. However, if the conditions continue like this, air conditioning will work to save lives, "said Steven Sherwood, chairman of the research team from the University of New South Wales in Sydney, as quoted by Discovery News, 15 December 2010.
Conditions that, Sherwood said, is not going to happen in the near future. "However, ignoring the global warming potential that is currently happening is a stupid act," he said.
Sherwood said that human beings can not survive if the skin temperature exceeds 35 degrees Celsius within a period of several hours nonstop. Although many people who live and even work in an environment temperature of 45 degrees Celsius or more, the sweat makes the skin they stay cold. Condition, the weather was not too humid.
Technically, humans can survive if the wet-bulb temperatures below 35 degrees Celsius. For information, wet-bulb temperature is the temperature recorded from the thermometer is covered with wet clothes and get proper ventilation.
"Limit the wet-bulb is basically a point where a person will experience overheating even if they are in a naked condition in the shadow, in wet conditions, and stand in front of a big fan," said Sherwodd.
Currently, Sherwood said, no one place on Earth that has a wet-bulb temperature over 30 degrees Celsius. However, if there is an increase in global temperatures reached 11 degrees, then there will be many areas of the Earth which will have a wet-bulb temperature over 35 degrees Celsius at certain periods throughout the year.
According to climate models used by the research team, these areas include the eastern United States, the entire Indian sub-continent, most of Australia, and some Chinese.
If current conditions continue, it is estimated, the earth's temperature will rise between 4 to 7 degrees Celsius in the coming year 2100. And if global warming trends do not change, the next 2300 years, Earth would be too hot. Not only for humans, but also for all other mammals, including animals.
Really hot temperature conditions ever experienced the Earth about 55 million years ago. At that time, most of the mammals perished and only a few species of dinosaurs that survived. (Umi) Read also: 10 Best celebrity blasphemed 2010
