ALSO WHAT IS YOUR OPINION ON GLOBAL WARMING
Man%26#039;s effect is a recent phenomenon of the last 150 years. In 1850, it is estimated there were 1 billion humans on planet Earth. By 1925, only 75 years later, there were 2 billion. But they were vaporizing mountains of coal and oceans of oil, in addition to burning grass and wood and animal dung. They had untold numbers of machines vaporizing fossil fuels, pumping tons of carbon into the planet%26#039;s ecosystem.
In just 37 more years (1962) there were 3 billion humans, and millions of cars and trucks and boats and planes and lawnmowers and tractors and...you get the idea. In only 14 more years (1976) there were 4 billion humans, and by 1986 (only 10 more years) there were 5 billion.
For some reason the latest estimates are that there are only 6 and one-half billion. After the rapid increases of the last 150 years I don%26#039;t know why that would be true, although millions have died in wars and drought.
But even if you take man out of the equation, global climate change is something Mother Nature does on her own. The last 11 thousand years (since the end of the last ice age) where man evolved the global lifestyle we have in 2008 have been abnormally stable.
There was a period called the %26#039;Little Ice Age%26#039; where the Earth cooled (1300%26#039;s to 1800%26#039;s I think), killing crops and disrupting life for many people, but other than that it has been a fairly stable period.
But in the 600,000 years prior to it there were much hotter periods and much colder periods lasting 100%26#039;s, maybe 1,000%26#039;s of years at a time. That wide-ranging climate change is Mother Nature%26#039;s norm; and it%26#039;s likely she%26#039;ll get back to it. Man may push Her to the %26#039;tipping points%26#039; that cause it. Our sheer numbers and the quantity of our carbon pollutions are significant factors.
The relatively short period of man%26#039;s increase from 1 billion to 6 and a half billion, and vaporization of mountains of coal and oceans of oil could be attention-getters. www.garyeandrews.com www.sustain360.org
Since these people are the ones that claim to care the most.
Then they should set the biggest example.
The fact that they set such a poor example tells the rest of us that one, global warming is a hoax or two the ones that claim to care the most really don%26#039;t.
Average global temperatures may increase by 1.4-5.8ºC (that%26#039;s 2.5 - 10.4º F) by the end of the 21st century. Although the numbers sound small, they can trigger significant changes in climate. (The difference between global temperatures during an Ice Age and an ice-free period is only about 5ºC.) Besides resulting in more hot days, many scientists believe an increase in temperatures may lead to changes in precipitation and weather patterns. Warmer ocean water may result in more intense and frequent tropical storms and hurricanes. Sea levels are also expected to increase by 0.09 - 0.88 m. in the next century, mainly from melting glaciers and expanding seawater . Global warming may also affect wildlife and species that cannot survive in warmer environments may become extinct. Finally, human health is also at stake, as global warming may result in the spreading of certain diseases such as malaria, the flooding of major cities, a greater risk of heat stroke for individuals, and poor air quality.
