Global Warming?

Question

if we dont stop making the world hotter and making the Ozone disinigrate.do you think their will be a living human or animal in the year 3000 or do you think that the earth will become to hot and everyone will die of extreme heat or the world will flood of the polar ice caps melting.

Answer 1

I don't think the situation is quite that dire, but, hey, what do I know?

Scientists aren't able to predict that far into the future because so much can change. However, there's only so just much fossil fuel for us to burn, so there's a limiting factor right there. My thought is that when we burn it all, we'll be back to the atmospheric CO2 situation before the catastophic event that killed and buried the dinosaurs about 65 million years ago.

Here's a graph showing temperature over the last 65 million years: http://en.wikipedia.org/wiki/Image:65_Myr_Climate_Change.png

The graph shows temp rising to an average 12 degrees (C) warmer than we have today. That's about 22 degrees (F). That's an average increase. I can't even begin to guess what that means in terms of number of days with temperature over 120 degrees (F) or even over 125 degrees (F) over how much of the planet, but I don't think summers will be much fun. The polar ice caps completely melt at about half that increase (6 degrees (C), same picture). So they will be gone.

The Greenland Ice sheet, representing about 10% of the world ice, would raise sea level by about 6.5 meters if it melted. (http://www.newscientist.com/article/dn9717-greenland-ice-cap-may-be-melting-at-triple-speed.html ), so if it all melts, it would raise sea level by about 65 meters. This does not include the thermal expansion of the water at the higher temperature. But anyway, we have a ball park figure and 65 meters is not going to flood the world.

Remember, this is a WORST CASE SCENARIO. And I see people surviving through it. But I don't think life is going to be as cushy as it is now.

Answer 2

Global warming is a fact however,we are increasing the rate of warming relatively slowly. Scientist say that we will increase our global temperature by 3 degrees in 100 years. This will raise sea level by about 1 meter. Add that up over 500 years and we have a bit of a problem. It's hard to say the intensity of damage we will leave for our future generations. I have faith that as soon as we are willing to recognize the problem then we will be willing to come up with practical solutions to the problem. The first step is to take responsibility for our actions.
My answer to your question is optimistic. I feel scientist will be able to reverse and compensate for our damage in the future. I also believe that we will stop our destruction, but only after our part in global warming is causing severe problems.

Answer 3

With the negative view u have there is nothing I can do for u.

Answer 4

The earth & mankind will be just fine..
The sky is not falling...
