Our Nasa scientists have measured this in
How fast can this go? Right now, I think our best measure is what happened in the past. We know that, for instance, 14,000 years ago sea levels rose by 20m in 400 years - that is five metres in a century. This was towards the end of the last ice age, so there was more ice around. But, on the other hand, temperatures were not warming as fast as today.
How far can it go? The last time the world was three degrees warmer than today - which is what we expect later this century - sea levels were 25m higher. So that is what we can look forward to if we don't act soon. None of the current climate and ice models predict this. But I prefer the evidence from the Earth's history and my own eyes. I think sea-level rise is going to be the big issue soon, more even than warming itself.

I have read several times about the rising of the sea levels and I have to wonder whether some of our purchase decisions as a world are actually speeding up the process. I understand the effects of global warming caused by our dependence on gasoline but what do you think about other purchases? We create so much waste. What about the purchase of pesticide treated foods over organic foods? What about the amounts of rubber we purchase hwo we dispose, or don't dispose of, our waste and other garbage articles? Would it be possible to change the imminent destruction you've quoted if we were all to start making different purchases? Or are we already at a point where the reversal of this problem can't be solved by our shopping choices? Whether there's an answer for this or not, it is an interesting thought and hopefully it can spur some interesting thoughts.
Here in our place, the weather is acting really weird. We’re expecting humid weather and scorching heat of the sun. What happens instead are heavy rains, super cold weather, and it’s really windy.
