CHANGES AND LOSSES

One things we are losing are the 3000 year old glaciers in the Arctic.  Having seen the Mendehall Glacier a little over two decades ago, even flying over that beautiful agua to turquoise shading, it is seriously diminished from melting and calving.  Read more on the Juneau Icefields by clicking here.  "
1894 
The Mendenhall Glacier reached its point of maximum advance in the mid-1700s, and its terminus rested almost 2.5 miles (4 km) down the valley from its present position. It started retreating in the mid-1700s because its annual rate of melt began to exceed its annual total accumulation. The glacier's terminus currently calves into Mendenhall Lake, where the water is 220 feet (67 m) deep. The ice is retreating at a rate of 100 to 150 feet (30 to 46 m) a year. At this rate, the glacier would take several centuries to completely disappear.
For Mendenhall Glacier to advance, the icefield's snowfall needs to increase, the glacier's rate of melt needs to decrease, or both. Glacial advance would require a reversal of the current warming trends."

2008
National Geographic has pictures of the and now.

It really doesn't matter why the change has happened for the average person.  It is scientists who are studying the rate of climate change.  However, to people who live near where farming is changing, water levels are rising, and the continuation of what they have done in the family for many generations is no longer viable becomes a serious problem.

Nevertheless, life is full of changes, not just the climate but technology is making many things obsolete but more expensive and replacements. are unaffordable to many   Without retraining for new jobs, many are no longer fit for available employment.  People ,who have refused to learn what computers demand, will not understand robotics.  They may take over jobs people used to have, but they still need people to run them, telling them what to do.

The most difficult part about change is that so many people view it as a loss rather than a gain, That, to me, is one of the major elements to distinguish Republicans from Democrats...the ability to adjust to change without great resistance.
