On global warming

[Saintaw]

Saw this stuff they did at greanpeace, took pictures at the same spot some pictures were taken some 50 years ago in the Arctic region. Check it out.

Even if it is from greenpeace, it's food for thought, I think.

I don't argue a warming trend, but....glaciers move.  What was farmland a mere 400 years ago is still covered by ice in many places.

Last I heard there have been several ice ages and warming trends for the earth. I thought that was the natural progression of things. I guess an environmentalist would conider change a bad thing and we'd all be running from dinosaurs if they had their way.

Perhaps we should also stop trying to cure disease as that is one of the major tools that nature uses to "thin" the population. We don't want to make a virus extict now do we?

Check out this guys site as a counter point to the Greenpeace stuff.

Best thing about global warming.

Or you can see what our Government is saying: EPA on Global Warming

According to the National Academy of Sciences, the Earth's surface temperature has risen by about 1 degree Fahrenheit in the past century, with accelerated warming during the past two decades. There is new and stronger evidence that most of the warming over the last 50 years is attributable to human activities. Human activities have altered the chemical composition of the atmosphere through the buildup of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide. The heat-trapping property of these gases is undisputed although uncertainties exist about exactly how earth’s climate responds to them. Go to the Emissions section for much more on greenhouse gases.

Don't be so quick to stick your head in the sand.

LOL, I swear I made the sand comment before reading gofasters post.

The glaciers ARE melting at an unprecidented rate.


Alaskan glaciers melting rapidly

FAIRBANKS, ALASKA - Melting has reduced former mountains of ice in Alaska to relative molehills more quickly than was expected, scientists say.

The researchers used an airborne laser device to survey 67 major glaciers. They found the rate of volume loss has doubled since the early 1990s.

You'll need to stick you head a bit further into the sand.

MT, is this the only 100 year period in which the surface temperature of the Earth has changed by 1 degree?  Is this the hottest the surface temperature has been since life existed on the planet?  Since humans existed?

[Nifty]

Thrawn, how fast did the glaciers from the last ice age melt?

What have been the perceived effects of the Alaskan glaciers melting now?

[Wlfgng]

every scientist, and most people, know the Earth has gone through climactic changes including ice ages and hot periods.

Nothing new there

what IS new is the RATE at which this is happening.

I think most people would rather not face it.  It's easier to just cruise through life without worrying about it.  But at what point does it 'catch' up with us?

Ready for the realities of this in our lifetime ?

Are you a climatologist? What makes you think your questions are relevant, or have not already been addressed? Are you suggesting that the EPA, NASA and other reputable groups have concluded that there is a human effect on the climate due to greenhouse gases, without asking those same questions?

"The findings suggest Alaska's glaciers contribute more to global sea-level rise than estimated – at least 9 per cent during the past century. "


I'm at work right now.  I'll try and find an answer to your first question on my next break.  If you have the time, feel free to try and find it yourself.

Remember, the surface temperature over the past century has been increasing at a geometric rate.

[Fatty]

Wlfgng that's why you don't marry her.  There will always be more.

[Nifty]

Where did I ever argue humans right now are not affecting the rate of change?

I'm actually hoping they have asked those questions and you have seen the answers so you could relay the answers, or point out your source.  It'd be interesting to see how the 1 degree increase of the past 100 years compares with other 100 years throughout the earth's history.   By finding comparable time periods, and examining the changes that happened within those time periods, perhaps someone could extrapolate the effects that the current trend might produce.

wlfgng, you're exactly right.  That's why I asked, how does the rate now compare with other rates in the past?  MT just told me how much it went up in the past year, not how it compared to the past.  I don't know.  I asked.  What's wrong with asking?  Same with Thrawn.  Glaciers are melting fast.  What's the effect?  Rising water levels?  Not here in the Gulf of Mexico.  Not noticeable at any rate.
