Thread: Global Warming

What are your thoughts about global warming? please state your reason for your answer?

Well its fact that global warming is happening, the debate is over if its man made or a natural event. Do i think the 1 degree (fahrenheit) its risen in the last 100 years to be a big deal. No.

I think it's a serious matter. You have the polar ice caps melting and the great coral reef slowly decaying. It might not look like a "big deal" right now, but wait a few more years and it'll become clear as day. If a scientist whose life's work is monitoring the arctic or great coral reef says there is something wrong, then I'm going to listen carefully to what they have to say. It would be irresponsible not to.

I don't think its as bad as people think... i mean, 90% of the ice is below the water right? and ice takes up more space than water... so if the polar caps melt, will the water level rise or fall? or stay the same?

As for CO2, its well documented that theres only like 0.038% of CO2 in the atmosphere... and if we removed all of that, plant life would die... plants NEED CO2 to live... (wood is almost half carbon)

The level will stay the same.

How can you say that? The water will clearly rise. The oceans levels have already started to rise with what has melted so far, water doesn't just appear out of no-where and make the oceans rise, it's coming from the polar caps.

You realize in the 1960's and 1970's alot of scientists where worried about another ice age. Nothing really has been proven as far sea level changes (how much how little when and where) It would take almost 20 thousand years to melt a little over 50% of the ice that is left causing around 100-120 feet in sea level rise.

20k years? we will probaly be more worried about global cooling by then .

Theres just so many things that humans havent worked out yet...

Apparently the magnetic field of the earth is supposed to swap every 100,000 years... and its been 680, 000 years since the last one, so we're really badly overdue....

Apparently theres hundreds of tonnes of asteroids and such that burn up in our atmosphere daily, and add to the earths mass... if all of that fell to the bottom of the ocean it might make a little difference to the ocean level...

Theres so many factors, science is only just beginning to work things out...

corynn and goo ball, you all are wrong. To keep referencing back to the 1970s won't help anything. Climate change is real and is backed up with data. Sea levels WILL rise due to polar ice caps melting. I explained this in another global warming thread. Ice that is not in water (land masses) such as antarctica will crack and fall into the ocean causing sea levels to rise.

Also, there is another serious matter that could arise. When fresh water that is trapped in the form of ice at the poles melts and enters the ocean, the salt levels in the ocean will decline. The decline in salt levels will disrupt ocean currents and possibly disrupt entire climates. Warm ocean currents bringing warm air to Europe could stop and Europe could be many degrees colder than it is right now.
