Morgan DeBoer opened a nine-hole golf course, above, at the mouth of Glacier Bay in 1998 on land that did not exist when his family settled in the area 50 years ago.

Glaciers around Juneau are receding 30 feet or more each year.

Read the article below for Tuesday 5/26. It discusses an interesting - and perhaps surprising - consequence of global warming.
