They're not. Without going into detail and at the risk of over-simplifying...
The planet has a maximum average global temp of 35°C and a minimum temp of 5°C. Several times in the past it's approached these temps following millions of years of warming or cooling. If the planet gets too hot or cold trigger mechanisms kick in and reverse the trend. There is of course one small problem here, the planet is currently operating beyond it's natural parameters and isn't behaving as it should.
If things are brought into check then we've about 10 million more years before global temps reach a low, then we've got about 60 million more years before they reach the next high. It's part of the natural (approx) 125 million year ice age cycle. Although it may seem strange, in the larger scheme of things the planet is heading deeper into an ice age and has been for a little over 50 million years. The recent warming, in geological timescales, is a blip in an otherwise downward temperature trend.
Across the surface of the planet there is a range of approx 80°C from the warmest place (Ethiopia) to the coldest place(Antarctica). There could be very significant temp changes and much of the planet would still remain perfectly habitable.
If temps fell significantly we'd see a migration towards the equator, if they rose significantly the migration would be toward the polar regions.
Turning to your specific point about GW. No-one can say just how much the temps will rise over the next X number of years but we can assign maximum and minumum values that provide a range. This has been done many times, ignoring the fringe and unreliable predictions they all arrive at a value of between a 2 and 5°C rise in temps within the next 100 years. This will have serious implications but it will most definitely not be the end of humanity or anything even close to it.

We are melting from about 10.000.000 years, the sea level rises 100 metres in past 100.000 years.
when Greenland and Antarctic continent melts the sea level will be more 100 metres, then would have passed more then 5.000.000 years.
At this moment the world will begin to freeze for more 15.000.000 years.
This cycle is continuous and the mankind do not have the power to slow or speed the nature course, because our solar system is governed by out space forces.
We with all technology affordable do not stop or slow a simple cloud

we have other ways to keep warm. Hydro electricity, nuclear energy, both of which dont send hydrocarbons into in atmosphere
check out al gores movie... (he really takes info and make it seem a lot worse than it actually is)
but id say within the next 15 years we wont be causing as much global pollutions.
id say we'll be fine.

Not for a long time. Which doesn't mean that we shouldn't care. There are also many other negative effects of Global Warming that are already having affecting people.

You or your children will see it if we do not change course.
The rise in temperature is not going to be the main cause of human death resulting from the current man made climate change.
Most human deaths will be caused by the wars over the use of water & food production as the climate change continures to disrupt food production and world populations have to migrate to avoid the rising sea levels.

I don't know where Trevor gets his "facts". In fact, the world is in an Ice age with glacial and interglacial periods. The cycle of warming and cooling is approximately 100,000 years. This cycle is most likely the result of continents moving to the poles and from variations in our orbit and axis of rotation. It is known as the Milankovitch Cycle. We have been warming and we are nearing the zenith as demonstrated by the bottom graph of the attached link. We should begin cooling in a geologically short period of time. In a few billion years, our sun will turn into a giant and if our ancestors survive to then, they will need to move.

Never, but read on.
It won't be a Hollywood style disaster. Gradually coastal areas will flood and agriculture will be damaged. But it will be very bad. Rich countries will cope, but it will take huge amounts of money. In poor countries many people will die of starvation, but not all of them.
Most scientists say, in 20-50 years. But we need to start right now to fix it, fixing it will take even longer than that.
Really good website for more information here:

Lots of numerical scientific data proving it real here:

IDK but that is so stupid about global warming! People dont care and they dont realize what they are doing! We humans need to make the world a better place and we need to cut down on doing that!

hmmmmmmm
its gonna be awhile
they say that Thoreau wrote charts of when flowers bloomed
in 1850 or so
they say from that , temps are 4.5 F higher than they wre then
so 45 degrees higher in 1500 years, folks will need a swim when its 145F
