Global warming or climate change, (don't forget it can also cool), is what has been happening for at least hundreds of millions of years.
The earth goes in and out of ice ages fairly regularly and we are in one now, it started about 2.6 million years ago.
During ice ages the climate can also fluctuate greatly, about 700,000 years ago it was much warmer than now, even 1,000 years ago it was a little warmer, so yes, between and during ice ages it will become warmer at times.
1000 years ago there was no global warming, just the normal warming of the earth by the sun. Global warming started when we discovered fossil fuels and started burning them seriously, at the beginning of the Industrial Revolution, about 250 years ago. This burning released age-old carbon dioxide that had been hidden underground for 300 million years. Carbon dioxide is a greenhouse gas, so extra gas in the atmosphere captures more heat, and this is global warming.
Global warming is adding heat to the oceans and the atmosphere. This extra heat is energy, which adds power to the winds. If the normal wind patterns change, then rain-bearing clouds may travel to different places, changing the amount of rainfall an area receives.
I do not believe that the normal air pressure of the Earth as a whole is terribly effected by so called "global warming". Maybe at higher altitudes where the air is actually "thinner(less oxygen content) there may be some effects but it is probably negligible.
Considering that the warmer temperature is melting the permafrost and releasing huge amounts of methane, the change in sea temperature is changing the climate patterns causing drought, the ocean levels have risen it may well be too late. The best we can hope for is to adjust to a new "normal" that isn't too hard on our species.
The major amount of human activities contribute to Antarctica's global warming. They add excessive amounts of greenhouse gases to the atmosphere. Green house gases pile up in the atmosphere and capture the heat that would, in a normal manner, escape into outer space.
It is normal to be at least a little skeptical of global warming. The biggest reason for this is that it is hard to appreciate what is often times a very slight increase in yearly temperature.
No, high temperature is normal for summer.
technically, the world won't go back to normal i fwe stop global warming. But if we plant trees and actually care about the environment like stop littering, we may be able to reverse its effecrs.
The realities of global warming are hotly debated in many scientific circles. Some scientists insist that statistics show the warming trend had stopped and temperatures had returned to normal by 2002. Others insist the worldwide warming trend continues to this day. Available data seems to indicate that if there is a global warming trend, the overall rise in temperature will be no more than 2 or 3 degrees F, and possibly much less.

To some extent, global warming is a natural event. Carbon dioxide is a naturally occurring greenhouse gas. At normal concentrations, it, along with other greenhouse gases, helps maintain global temperatures at a level that is comfortable for humans and other animals that have adapted to the present climate. Throughout human history until the Industrial Age, atmospheric carbon dioxide levels were in the range 260-280 parts per million (ppm) and never higher than this. This is the natural part of global warming. By adding new carbon dioxide to the atmosphere, which we do by burning fossil fuels such as coal, oil and natural gas, and by cement manufacture, we interfere with the natural process and create enhanced global warming, which is not natural.
then the normal amount if carbon dioxide will rise in the atmosphere.so then the gas will absorb long wave radiation causing global warming.
Gasoline, or petrol, is a fossil fuel. When it is burned it releases carbon dioxide (CO2). This CO2 is not part of the normal carbon cycle which moves carbon in and out of the atmosphere. This is CO2 that has been hidden away underground for millions of years. Releasing this is adding more gases to the greenhouse effect, which is why the earth is warming all over. This is global warming.
The normal greenhouse effect keeps the earth warm enough for life.The enhanced, or accelerated greenhouse effect, is causing global warming.
No. The normal cycle of the earth heating and cooling happens over thousands of years. This current global warming has been sudden and rapid, since we began burning fossil fuel at the start of the Industrial Revolution, but more especially in the last 60 years.
Global warming is adding heat to the oceans and the atmosphere. This extra heat is energy, which adds power to the winds. If the normal wind patterns change, then rain-bearing clouds may travel to different places, changing the amount of rainfall an area receives.
There are no real effects. There is no evidence that global warming is real or, that its happening. The truth is during the civil war we experiences a minor ice age and the earth lost a few degrees, now we are just gaining them back. The earth is not heating up it's simply going back to normal temperature.
