I keep hearing all this talk about global warming and I'm curious to learn when it supposedly began to happen. Was it 20 years ago, 50, 500, 2000?

Its a bunch of hoo-ha. You must believe everything Al Gore spews.

Global warming is a bad term to use
The warming refers to the suns rays being trapt in the earths atmoshpere by a rise in CO2 in the atomsphere.
They are called greenhouse gaes because they trap the Suns heat in the atmosphere.
Now, this is good until it reaches a certain pint and that is where we are today.
Global Warming actually means global climate change.
Here in California we are having the dryest winter seasons in recent history while on the east coast record snowstorms are occuring.
Global Warming- the bad one- has been going on since industrization in America in the 1850's - but the good one is a natural occurance with Ice Ages and Dry Ages.
8 of the last 10 years have been in the top 10 hottest years on record since 1800.
If that isnt conclusive I don't know what is.

In California in the past 25 years it has warmed 2 degrees in all the urban areas. Out in the country side the average temps are still the same. So says a recent study by the Univ of Cal and the weather burea. Conclusion? Quit putting down concrete and asphalt.

Once the scientists that were screaming Ice age, realized nobody cared, to make $$$ they changed it to global warming. Mid Apr it snowed in Pa. Global warming is a hoax

According temperature trends inferred from ice core data, the current warming trend began about 20,000 years ago.

11,000 years ago, at the end of the Wisconsonian Stage of the Pleistocene Epoch. There used to be 2 miles of ice sitting atop of Wisconsin and it has retreated to where it is today.

It's complicated because a number of things affect climate. Check out this graph:

Global warming as we know it began about 1970, when man's increase in greenhouse gases got very large, coupled with a decrease in man's emission of particles ("sulphate") because of pollution controls on that.

Are you asking about the latest case or the countless times it has happened before, along with global cooling.

billions of years ago - it keeps on cycling - in fact i n the last 30years Mars is in the middle of a warming - could it be solar or perhaps we on earth are also wrecking another planet - the answer is mass suicide of the human race

"global warming" has been going on since the planet was created. it is always going through hot and cold spells.
