This is a question about GLOBAL WARMING, not POLLUTION. They are completely seperate topics.

I agree that we pollute the Earth, so you don't need to tell me that.

man, we have been in a stage of global warming since the end of the ice age

Greenhouse gasses keep our planet Earth warm and habitable. If not for the greenhouse effect of our atmosphere our planet would be a giant frozen iceball. During the long history of our planet there have been episodes of global warming and global cooling. While planetary pertubations and variation in solar output have played some role in this, most of the variation has come from changes in atmospheric gasses. Sometimes evolutionary processes have contributed to this (evolution of phytoplankton, evolution of gymnosperms, etc.) and sometimes geological events like supervolcanic eruptions.

Volcanoes affect the atmosphere because they put carbon dioxide into the air, which traps heat and leads to global warming. The greatest volcanic activity the Earth has ever seen, 251 million years ago (mya) covered Siberia in lava flows several hundred feet deep (Siberian traps) and caused the Earth's temperature to rise 26 degrees F. The result was the sudden extinction of 90-96% of all life on our planet (Permian/Triassic mass extinction event). The geological sediments following this era are known as the "dead zone." A less extreme supervolcanic event warmed Earth 14 mya bringing about tropical forests in Europe. All polar ice melted and Florida was under 200 feet of water (go look for marine fossils at Cargill Mines in Florida sometime). Another supervolcanic event ended the Pleistocene Ice Age.

Human activity, such as the burning of fossil fuels, puts a lot of carbon dioxide into the air, enough so that we now mimic a supervolcanic event. Unless we want to see the consequences of a Florida 200 feet under water or the sudden extinction of 90% of species, perhaps we should then take global warming more seriously.

We are responsible for about 2 % of the warming from the extra carbon dioxide (Mostly from Al Gore's jet), the other 98% comes from mother nature especially the ball of fire that is 333,000 times the size of the earth , the volcanoes in Hawaii , Mexico and maybe a cow in India who ate too much curry .

"...humans are responsible for global warming?..."

Absolutely NOT..! Global warming / cooling is a *natural* cycle that Earth has experienced countless times in the past. Hard scientific evidence proves this. The current cycle is going to happen no matter what mankind does or Al Gore says.

Yes, because of the data. Here's a short summary. It includes all of the usual suspects, the sun, volcanoes, etc. I don't know why people think climatologists don't include data on those things in their analyses. Of course they do.

Longer version (also includes the sun and volcanos):

Scientists have seen much stranger things than global warming (like Einstein's relativity or quantum mechanics) proved to be true by data. So the data, not "logical" arguments, is what they go by. The data is why the vast majority of scientists agree that it's real and mostly caused by us. Data about that here:

I always have known that exactly people are responsible for global,because they pollute the athmosphere,condaminate water!We as human damage the world!

If there were no humans the earth would be warming anyhow. Humans may be contributing to the warming but that's not proven.

Not totally .... In fact no one can say how much we're actually contribute to it. Solar output has gone up about .2% in the last 40 years and Mars and Pluto are heating up also... Here's a 2003 article and people seem to ignore these kinds of facts.

I'm sure we played our part. But to my understanding volcanic eruptions and methane gas plays a big part in ozone depletion
