Using science, facts and data? You should be ashamed! Let me see if I can guess the usual responces

Scientists only monitor a small percentage of world glaciers so their numbers are not accurate!

Scientists knew in the 1970's that we were moving into an Ice Age and we are experiencing global cooling!

The sun is causing it! Unusual sunspot activity is warming all the planets up!

It's cyclic! The planet naturally warms and cools.

Mankind cannot effect the environment because god made it and god would never allow mankind to destroy his work!

Did I miss any?

Warming will be good.

It's too late to do anything anyhow.

		<FONT size="5" color="#008000">What is mass balance? </FONT>Crucial to the survival of a glacier is its mass balance, the 
				difference between accumulation and ablation (melting and 
				sublimation). Climate change may cause variations in both 
				temperature and snowfall, causing changes in mass balance. 
				Changes in mass balance control a glacier's long term behavior. 
				It is the most sensitive climate indicator on a glacier.  A 
				glacier with a sustained negative balance is out of equilibrium 
				and will retreat. A glacier with a sustained positive balance is 
				out of equilibrium and will advance.  A glacier that cannot 
				retreat to a new point of equilibrium due to negative balances 
				will disappear.</B></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.nichols.edu/departments/glacier/global%20glacier%20mass%20balance.htm"><div align="center"><img src="http://content7.clipmarks.com/blog_cache/www.nichols.edu/img/05EAED43-2C3A-4D56-B7F9-BBAD70B66122" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.nichols.edu/departments/glacier/global%20glacier%20mass%20balance.htm"><H2><FONT size="3">Figure 1 Annual global glacier mass balance change
