Excellent point, a number of civilizations have collapsed due to climate change. None of which were triggered by mankind.Actually if you look at say, the great empires, what we see is a decline when things get too hot.
The Egyptians were followed by the Greeks and then the Romans. As things changed so too did the areas able to sustain great empires.
Are equatorial countries at the top of the GDP pile? No, in fact it is mostly countries in milder climates, Europe, China, Japan, North America, etc.
What is this? Climate change primary school edition?
Who is saying climate change hasn't happened in the past? No one, not a single person. So why are you trying to make a point as if people have said this?
There are two things.
Climate change and MAN MADE climate change. You see the difference?
One is natural, the Earth goes through phases. What happens happens. However with man made climate change we can't say what the impact might be....
if man can impact the climate like you say
then there is no need for natures "what happens happens"
Why?
We can impact, we just can't control.
We do probably impact the climate a bit. And if you know the cause -- it MIGHT be preventable. CO2 has a diminishing effect on the GreenHouse. For every degree in temperature you get from increases in temperature -- you need TWICE as much CO2 to get the next degree. And water vapor is by far the LARGEST GHouse gas contributor. The GW theory states that man-made emissions are just the "trigger" to a runaway GH effect. That's the part of GW that is hotly debated and certainly not settled.
Well, there are 7 billion people on the planet. Within a few decades this will rise.
China has about 1.3 billion people, and rising, quickly. The one child policy is rocking because of social issues, the Chinese are getting richer, they're using three times more oil now than 15 years ago and this is with half the country still in relative poverty. India has the potential to get richer, as do many other countries, and with this comes more consumption of fuel and more pollution.
We don't really understand what's happening with CO2. Some suggest that the sea is taking in a lot of this CO2 mitigating the impact, but then what happens if the sea suddenly can't take it any more and all this CO2 suddenly increases by four, five, six fold or more?
Yes, water vapor is the biggest greenhouse gas. But it's always been there. The Greenhouse effect exists for a reason and we've developed as a world within these parameters. But we're changing these parameters and we don't know what is going to happen. If something goes wrong, there is no turning back.
