Global warming this time began more then 250 years ago when we first discovered how to run factories and power them with coal-fired steam engines. At that time there were about 1 billion people on earth. Since then industrialisation, electricity generation and transport have been pumping carbon dioxide into the atmosphere so that there is more than there ever was before.
A:Since the increase in coal-burning at the start of the Industrial Revolution, and accelerating with the advent of the internal combustion engine.A:
The warming of our planet and retention of heat has been going on for millions of years. If you are thinking about the current warming cycle we have been experiencing, that began 10,200 years ago.
Since the middle of the 20th Century and earlier.
Global warming refers to the long term increase of the earths temperature. It is directly linked to climate change but is not an interchangeable term for it.
Currently scientists are uncertain as to how global warming would affect tornadoes. This is further complicated by a lack of complete, long-term tornado records. So far no substantial link has been discovered.
If global warming continues, not that long from now.
Since the industrial revolution from about 1800 man has been releasing enormous amounts of CO2 into the atmosphere causing the green-house effect and leading to global warming. The process has accelerated as the population of the Earth grows and more countries get industrialised.

Global Warming, that is the warming of the earth since the beginning of the Industrial Age, began when man discovered fossil fuels some 250 years ago. There were commercial coal mines in the US state of Virginia in 1740.
1. How long will it stays? 2. How can we be able to succeed over global warming? 3. What can we do to stop it totally?
The American Policy Center (APC) say this because they are global warming skeptics. They believe that global warming is not happening.
Global warming is long term changes - increases - in the global temperature.The increases in the global temperature are being caused by the accelerated greenhouse effect. That is, more greenhouse gases in the atmosphere (methane, but largely carbon dioxide from our burning of fossil fuels like coal, oil and gas) capture more of the sun's heat and warm the atmosphere. This extra warming is global warming.

No because the Kyoto protocol assumes human beings are responsible for global warming. This is unlikely to be the case because the earth has gone through numerous cycles of warming and cooling going back long before human beings were a significant presence on this planet. Ever heard of the Ice Ages? There were several. Global warming and cooling are a function of solar activity and people can't control the sun.
Shortly after the '70's when the same fools lost the argument about the coming ice age.
no one knows for how long it will take for them to die out but i hope its not for a long time. they were going to die with hunting but now that is controlled by law and now global warming i think they are doomed.
