Millennia pass and our population numbers soar. ... Disease as "nature's" population correction, rapid die-off from famine, disease, etc. are now an insufficient correction of over-population. these forms of die-off are not very efficient or effective in the long run. That is to say, human populations respond to stresses of this nature with remarkable resilience. ... The U.S., with only 4% of the world's population, creates 25% of its greenhouse gases. ... Mr Reinstein, 58, attended the conference as a representative of the Canadian Electricity Association, and was! ...

Global Warming - Its Implications on the Human Population Though there is some scepticism that climate change is a result of human actions, it is unlikely to be a natural event. ... These figures are not consistent with a natural trend, and, when one considers the tens of thousands of years in which humans have inhabited the earth, and that humans have really only started burning fossil fuels heavily since the industrial revolution, and the fact that the world's population is only going to increase, this number is dauntingly enormous. ...

Atmospheric Structure The gaseous area surrounding the planet is divided into several concentric spherical strata (31k jpeg) separated by narrow transition zones. The upper boundary at which gases disperse into space lies at an altitude of approximately 1000 km above sea level. More than 99% of the total atmospheric mass is concentrated in the first 40 km from Earth's surface. Atmospheric layers are characterized by differences in chemical composition that produce variations in temperature. Troposphere The troposphere (14k jpeg) is the atmospheric layer closest to the planet and c...
