Editor's Column

The Late Great Glacier

The End of the Ice 
by Laura Johnson, President

Temperatures Rising

There is a big difference between weather and climate. Climate is what you expect. Weather is what you get. But through millennia the climate can be as variable as the weather.

The Once and Future Salt Marsh

Changing climate causes rising sea levels and alters coastal marshes. In the past, marshes merely migrated inland. Now they’re often blocked from doing so by coastal development. 
by Robert Buchsbaum

Long Trail in the Sky

The phenomenon of long-distance bird migration probably has origins that began long before the last glacier even began its advance, though current patterns may have been established after the glacier retreated some 11,000 years ago.

Climate Change in the Age of Denial

In spite of the fact that sea levels are rising worldwide and remote glaciers are melting dramatically, there are still people—some of them in influential positions—who do not believe in global climate change.

The Myth of the Unchanging Forest

The so-called forest primeval was always in transition in response to climate changes. Now, with warming trends advancing more rapidly than ever before as a result of human activities, how do we preserve natural communities?

How Glaciers Make Warblers

Moving southward in retreat from the advancing glacier, and cut off by vast tongues of ice, various populations of warblers were split apart, and evolved into subspecies and entirely new species.

Our Favorite Landform

The famous drumlin of Drumlin Farm is one of many such glacially created geologic features spread all across the region surrounding Boston. As were many drumlins in the past, ours is used for grazing. 
by Ann Prince

Learning from the Glacier

Landforms around the Northeast were altered by the glacial advance and retreat over a period of millennia. Now climate and ultimately the landscape we know are changing faster than ever before. But how do we create the political will to act on changes that will play out over a generation?

Not Taking the Heat 

Mass Audubon is significantly reducing its own carbon footprint, working to help others do the same, and considering the health of ecosystems in the face of climate change impacts in Massachusetts.
