The ‘bird’ has flown!

The ‘bird’ has flown! Voices are raised in celebratory cheers from the southernmost continent to across the U.S. Our first ALAMO float is deployed! Now we can begin to answer some of the big questions on this mysterious ice/ocean interface.

‘Ghost Ice Shelves’ and the Third Antarctic Ice Sheet

The Antarctica Peninsula has been referred to as Antarctica’s third ice sheet. Following behind the East and West Antarctic ice sheet in size, one might be inclined to minimize its importance in the effects of melting Antarctic ice, on changes in sea level and other impacts, but that would be an imprudent mistake. The peninsula is Antarctica’s most northern spit of land; like a crooked finger it stretches out beckoning towards the southern tip of South America and her warmer climate.

A Front Row Seat on the Ocean Floor

Ocean scientists are, in their hearts, explorers. Our group aboard the R/V Atlantis may be more infected with the exploration bug than most. The first goal of our expedition makes that clear: We aim to map regions of the seafloor never before seen by human eyes.

The Domino Effect

Ice shelves can behave like dominos. When they are lined up and the first one collapses it can cause a rippling effect like dominos. We have seen this with the Larsen Ice Shelves. Named in series, the Larsen A, B and C shelves extended along the northeastern edge of the West Antarctic Peninsula, and covered a large swath of coastline as recently as twenty years ago.

Pine Island Ice Shelf

A First Meeting with an Old Friend

If you have studied the impacts of climate on Antarctica you have encountered Pine Island Glacier. Tucked in at an angle under the West Antarctic Peninsula handle, this seemingly innocuous glacier has been making headlines for years as one of the fastest flowing ice stream glaciers on Earth.

Year by Year, Line by Line, We Build an Image of Getz Ice Shelf

Changes in Antarctic ice have been dominated by the interaction of the ice and the ocean, and because ice shelves extend out into the water they are vulnerable to melt from the warmer ocean water. Melt can affect them in two ways, through thinning along their length and through causing a retreat of the “grounding line.”

How to Prep a City for Climate Change

Cities around the world already have begun responding to climate change, and a new report from the Earth Institute provides a deep analysis about the risks they face and a detailed look at what some cities are doing about it.

Putting Garbage to Good Use with Waste-to-Energy

Burning garbage to produce electricity is a strategy for sustainable waste management that is finding favor in Europe and China. Why isn’t it practiced more in the U.S.?

The Coming Great Quakes in India and Bangladesh?

A new film takes viewers from the eastern highlands of India to the booming lowland metropolis of Dhaka, the capital of Bangladesh–and explores an ever-more detailed picture of catastrophic earthquake threat that scientists are discovering under the region.

Richard Plunz will talk about the newly revised edition of his "History of Housing in New York City" Wednesday, Oct. 19, at 6:30 p.m. at the Museum of the City of New York. For details and to register, visit the museum’s website.

Housing in New York City: Updating the History

“Beyond doubt the large question facing New York housing production today has to do with a market that can not provide for the half of our households that are low income.”
