Global warming is a long term effect, from a human perspective. One of the last major changes in atmospheric carbon occurred about 50 million years ago, and is known as the "Azolla Event." Azolla was an arctic freshwater fern that pulled CO2 from the atmosphere, then sank to the sea floor where that carbon was sequestered. Over several hundred thousand years atmospheric CO2 fell dramatically, precipitating an ice age.
Today humans have been busy digging up ancient coal beds and pumping oil lying buried for millions of years, and burning it. The CO2 released by this activity is expected to linger in the atmosphere for many centuries, gradually increasing earth's temperature. The rise in CO2 has been extremely rapid, from a geologic perspective, and is likely to remain in our atmosphere thousands of years--possibly a few million years.

What is global warming activity?
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.
How long has global warming taken place?
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.
What has led to global warming?
In eons past earth warmed and cooled for a variety of reasons, most notably due to long term oscillations in orbital periods known as "Milankovitch Cycles." At the present time global warming is due primarily to the consumption of fossil fuel. Humans release over 30 billion (30,000,000,000) tons of CO2 into the atmosphere from the oxidation of fossil carbon (primarily coal and petroleum) each year, where this heat trapping gas accumulates.
When will there be no more ice caps?
If global warming continues, not that long from now.
How long has global warming been a problem?
Since the middle of the 20th Century and earlier.
How does global warming cause long-term changes in the global temperature?
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.
What were the short and long term effects or the eureka stockade?
the elong and short term effects on the eureka stockade was that there was more global warming.
What are the short term and long term consequences of ozone depletion for Antarctica?
Short term can cause personal problems. Long term can cause global warming.
Controversies such as those surrounding global warming and ozone depletion involve long-term prediction and therefore are undecidable in the short term?
Yes they are long term. They cannot be predicted for short term.

What do you wonder about global warming?
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?
Why does the APC say that it is impossible to predict that something like global warming can happen so long from now?
The American Policy Center (APC) say this because they are global warming skeptics. They believe that global warming is not happening.

Is global warming another term for the greenhouse effect?
No. The greenhouse effect is the process by which certain gasses, called greenhouse gasses, help to trap heat within Earth's atmosphere. This effect has been in place for as long as Earth has had an atmosphere and is necessary for life to exist. Without it, the planet would freeze over. Global warming is primarily the result of an enhanced greenhouse effect, caused by extra geenhouse gasses entering the atmosphere.
What is global warming and what are you doing on earth to influence global warming?
Global warming is the long-term increase in the Earth's average temperature. Right now human greenhouse gases, mainly from burning fossil fuels, are causing global warming by increasing the greenhouse effect. The way to slow global warming is to reduce our greenhouse gas emissions. On an individual level, people can accomplish this by using less energy at home (almost half of the energy in the USA is produced by burning coal), and by driving less. On a larger level, people can support efforts to put a price on carbon emissions.
