Not so much. Global warming and cooling has been ongoing for as long as there's been an earth. There's concrete evidence of warmer periods than we have now and much colder ones. I say, it's mostly a natural cycle.

The earth *is* a living entity, if you think about it. The last ice age ended 12,000M years ago (there is no 'accurate' time, so it's each to their own where you might collect information from.) Using that figure, then it's taken that long for earth to warm to it's current state. Recent figures caused by Greenhouse Gases, which are hotly debated, are said to be causing the earth to warm. Also, consider that the last ice age was the last ice age, there have been more than one ice age according to Science. That puts the planet into a state of flux *if* we consider that it's gone through more than one ice age and 'recovered' (for want of a better ex<x>pression). That being the case, then it raises the argument that even though the earth's surface is getting hotter, the *same* thing could have happened many millions of years ago when mankind had not, at that time, existed.<br />
<br />
It depends where you stand on the issue. I tend to lean to believing that the planet 'lives' and this is a stage it's going through. Greenhouse Gases is hardly built on a sound foundation if we consider that early studies and data collected came from no more than 5 Scientists and their findings. Global Warming is ba<x>sed on these findings; many argue that those findings aren't a strong enough case to prove that Global Warming caused by Greenhouse Gases, rather than a natural occurance, is a fact.<br />

What I believe is that the earth naturally works on a very specific system so putting things into the atmosphere that don't belong there are having an effect. I also think it's silly that people are content to argue about global warming as if the question wasn't simply about limiting the amount of toxins we create in our own environment. Even if the unusually dramatic shift in temperature is not cause by pollutants, do you really think, the fact that most of those substances are proven to be detrimental to us, flora, and fauna, isn't?

Yes.<br />

People get confused about that fact that our climate has changed many times over the long years our planet has existed, and they pooh-pooh global warming and say that it is natural. That is the whole point. What we are doing is causing the temperature to change very quickly and it is a result of our activity.<br />
<br />
The bottom line is, it is a self correcting problem.

If you increase the population of any species ,.but especially humans,.you will get a reaction from the environment..The amount we consume and burn ,.especially over the last 200 years,.its no surprise that the atmosphere is affected..There are many measurement6s which have never been seen before ,including the sheer number of humans and the average impact we now have...<br />
The amount of oil ,coal ,and gas we burn each day is phenomenal..<br />
Add to that the destruction of so much ecosystem ,in a myriad of ways ,and its no wonder that Nature is in a spin..You cannot just trash a place and expect for it not to trash you back.<br />
People may argue if its caused by humans or not,.but in the end ,the results will be the same.
