How old is global warming?
The theory of global warming became popular in the early 70's. As for how old actual global warming is, is debatable. Some argue that global warming is a natural cycle the earth goes through every so many centuries.
How many years has global warming been there?
The greenhouse effect has been keeping the earth warm for millions of years. But the global warming that the world is worrying about now started about 260 years ago, at the beginning of the Industrial Revolution (around 1750), when man started digging up coal and oil and burning it for industry, transport and to generate electricity.This fossil fuel burning releases age-old carbon dioxidethat had been hidden underground for 300 million years. This extra CO2 is too much for the carbon cycle to deal with so it remains in the atmosphere, getting warmer and warmer as the months go on.
How long has global warming effected the earth?
Approximately 4 billion years, give or take a few million years. Since the beginning, the earth has gone through continuous warming and cooling periods. For instance, about 200 million years ago dinsoaurs were roaming around the jungles of Colorado. Global cooling might have been their downfall. More recently, glaciers covered most of Wisconsin about 700,000 years or so ago. Since then there have been as many as 10-12 glacial advances and retreats. The most recent major glacial advance peaked out about 20,000 years ago, then global warming set in and glaciers retreated for about 10,000 years after which there was a slight glacial advance. The earth warmed again and peaked around 5,000 years ago. The warming period since the last major glacial advance was when man started developing agriculture, and have more time to invent stuff. About 2000 years ago there was a minor glacial advance in some areas, then warming. About 500-600 years ago the "little ice age" began with cooling temps that lasted to the mid 1800's. Since then it has been warming except for a cool down from about 1940-1970 when some scientists thought we were going into another "ice age". Since the mid 70's things have been warming rapidly. This warming has been a great opportunity for some folks to blame all global warming on human activities. So far I don't think anyone really knows for sure, but whatever the cause, it could have profound effects on all life on earth, just as it always has.
How is global warming affecting temperatures?
Global warming occurs when the greenhouse gases in the atmosphere capture the sun's heat reflected off the earth. More and more carbon dioxide retains more and more heat. This is increasing the temperature of the world.
Could governments have done more in the past to prevent global warming?
Yes, we have known about global warming since about the middle of last century, but governments have been slow to act. Politicians rarely can see beyond the next election, and action on global warming takes some years before we see a result. Now, as global warming and its effects are beginning to be more obvious governments may act.
Does global warming bounce?
No, global warming has been rising steadily since the beginning of the Industrial Revolution. Most of the warming has taken place in the last 80 years, but there is no bounce.
What is the number of years of data needed to predict Global warming?
Scientists have been using the data over the last 250 years (since the start of the Industrial Revolution) to monitor the rise of Global Warming.
What is the average winter temperature in Montana?
about 0F, but with global warming the last few years have been about 25F.
Why is the earth so warm in the last 10 years?
Global warming. Do you go to school.

What is the last age in simcity creator?

How has the Earth's natural warming system been thrown out of balance over the last 200 years?
earths natural warming system been thrown out of balance over the last 200 years
What are two signs of global warming on the planet within the last 100 years?
Within the last 100 years there has been a 1 degree Fahrenheit temperature increase in the United States. The warming is uneven. Alaska has warmed about 5 degrees since 1960.Sea levels have risen globally by 1.8 mm per year for the last 100 years.
Did global warming bother humans just after the ice age?
After the ice age, humans likely did not directly recognize or attribute global warming as a concern. Instead, they would have been more focused on adapting to the changing environment and finding ways to survive in the new climatic conditions. The concept of global warming as a result of human activities is a more recent understanding.
How many global warmings have been taking place all around the world?
There have been various periods of warming and cooling through the history of the earth. They typically last for thousands of years, often tens of thousands. At the moment there is only one global warming taking place. This one has been happening since 1850 and is the fastest the world has ever seen.
Is global warming a rapid or slow change?
Global warming is a rapid change. The earth's temperature has risen very fast in the past 50 years, compared to the very gradual rise over the past 12,000 years, the time of the last Ice Age.
What are some examples of climate?
The change from the last Ice Age till now. This took 12,000 years.The present climate change caused by the global warming that has been happening since the Industrial Revolution. This rapid warming has been most noticeable over the past 50 years.
