Climate change continues to pose a major threat to polar bear survival.  Polar bears, whose native range largely lies within the Arctic Circle, depend on sea ice for nearly all of their life cycle functions.  And rising global temperatures are causing that sea ice to disappear.

The changing climate has many effects upon the world’s ecosystems, some of which are surprising.  One of these relates to the effect of the increasing melting of ice in the Arctic.  The ice melt is leading to more life in the Arctic sea.

An oasis is an isolated area of vegetation in a desert, typically surrounding a spring or similar water source such as a pond or a small lake.  Oases can provide habitat for animals as well as people.   Oases have long been essential for trade and transportation routes in desert areas; caravans typically travel via oases so that supplies of water and food can be replenished.

Spring is the time of the great monarch migration when the butterflies leave their wintering grounds in Mexico and head north to Canada.  As we have been saying for quite some time, fewer and fewer butterflies have been making the trek each year.  Twenty years ago, a billion monarchs swarmed the winter site in Mexico.  In 2013, the number was down to 33 million.
