Fact 5!...?

Fact 5:
Snow from the tops of mountains are disappearing because of global warming.

Source 1:

1. The source is Bill Farrel

2. Credentials: once a NASTAR (National Standard Race) pace setter

3. The source is fairly credible.

4. The source says, "Between 1950 and 1997, springtime mountain snow cover in the Rockies was down 16 percent, the Cascades lost an average of 29 percent, and many sites in Washington, Oregon and Northern California saw springtime snow down more than 50 percent."

5&6. I believe this source because the correlation seems to be obvious and does relate to one another.


Source 2:
http://nsidc.org/news/press/20070623_PainterGRL.html

1. The source is Tom Painter

2. Credentials: scientist at the National Snow and Ice Data Center

3. The source is very credible.

4. The source says, "'Recent studies agree that with global warming, the southwest U.S. will be warmer and drier. Enhanced dust deposition is likely, further shortening snow cover duration,' Painter said. 'Ultimately, a warming climate and the dust it generates will affect river runoff and soil moisture in the mountains, not only in the western United States, but across many of the world's mountains.'"

5&6. I believe this source because the information is clearly shown that they are all related with each other.


Source 3:
http://www.ccchina.gov.cn/en/NewsInfo.asp?NewsId=4516

1. The source is He Yuanqing.

2. Credentials: it is a .gov website, it is copyrighted

3. The source is fairly credible.

4. The source says, "The main cause to the glacier retraction in Yulong Snow Mountain is global warming, according to He Yuanqing, an expert from Chinese Academy of Science. "

5&6. I somewhat believe this source because they do not provide a lot of information to back their statements up.


I believe this fact because there seems to be a lot of information that supports this fact. The correlation also seems to be very logical
