Is global sea level rise further proof that global warming has not stopped? We%26#039;ve now established that there%26#039;s no evidence that global warming has stopped.

http://answers.yahoo.com/question/index;...

One answerer in the question linked above claimed that decreasing sea levels are proof that the planet has stopped warming. However, his source indicates otherwise:

http://sealevel.colorado.edu/current/sl_...

As you can see, since 1994 the global sea level has increased 3.2 mm/yr. As a reference, over the past 2000 years the rate was approximately 0.1-0.2 mm/yr, and over the past 100 years was 1-2 mm/yr.

As the answerer noted, the two primary causes of sea level change are ocean temperatures (thermal expansion) and amount of land ice. Both are obviously related to global warming.

So considering the fact that sea levels continue to rise, is this not further proof that global warming continues?

gcnp - correct, I should have said %26quot;evidence%26quot; rather than %26quot;proof%26quot;

Dave - so first deniers argued that global warming had stopped in 1998, then 2001, then 2003, and now 2005? Next you%26#039;ll be arguing it stopped yesterday LOL!

(Discussion of sea level begins on p 408)
(see FAQ 5.1 on p 409 for decent summary)

And I hate to carp, but it%26#039;s not proof, it%26#039;s evidence. Very strong evidence, but still only evidence.

Edit: Jim, you remind me of this:

(for what it%26#039;s worth, the Kent Univ. cartoon archive is a great thing to while away an hour or so bouncing around. The collection of David Low is just phenomenal.)
Is there anything on the attached chart that you disagree with. Do you think humans caused the rise 16,000 years ago, or the steady rise since 10,000 years ago. Is there anything you believe that isn%26#039;t alarmists?

The Sea Levels are dropping.

The Oceans are cooling ftp://ftp.ncdc.noaa.gov/pub/data/anomali...

and the globe is no longer warming http://hadobs.metoffice.com/hadcrut3/dia...

If the increased CO2 in the atmosphere is increasing the greenhouse effect and trapping more heat, then where is all this extra energy going?

Wow you made a lot of bold assumptions... most of which aren%26#039;t even correct.

1. We haven%26#039;t established that global warming continues... fact is the world is cooler now than it was 5 years ago.

2. Decrease or increase in sea levels doesn%26#039;t say anything about global warming. Too many thing impact sea levels. Decrease in river beds for flood control creates and increase in sea levels... eroding land mass that is then carried into the oceans increases sea levels... alot of thing impact sea levels that have nothing to do with warming or cooling of the planet. In fact some of the things people love to claim increase sea level don%26#039;t, such as melting of the polar ice cap.... people love to claim the north pole ice melt is increasing the sea levels, in fact the opposite is true go fill a glass with ice and then put water in it so the water is just to the top of the glass... now let it melt... guess what the water never overflowed, because ice is less dense than water ice actually caused the water level to be higher when the ice melted the more dense water allowed the level of water in the glass to shrink.

So when sea levels rise you can ask why, but don%26#039;t assume it has anything to do with temps it could be other reasons.

The modest (.6deg.C) rise in temperature over the past 100 years is indicative of global warming, yes. And because of it there is bound to be some glacial and land-ice melting, though not on a large scale obviously because the rise is minimal.

What needs to be recognized is that the temperature increase was a natural phenomenon. The earth warms, and the earth cools all the time. Sometimes gently, other times alarmingly. Changes range from unnoticable to ice-age levels.

Because of the natural events that cause these fluctuations, and considering that man is either not a partner or so minimal in any cause we should overlook and forget what%26#039;s happened. We have no responsibility for natural events, nor should we be acting to change them.

If sea levels have actually risen (some evidence also shows they haven%26#039;t), it is only because of natural trends and is not proof of anything man-made.
I didn%26#039;t open the second link because we all know that sealevels haven%26#039;t risen enough to reach Colorado.
