We can’t immediately link Hurricane Sandy itself to climate change, says climate scientist Cynthia Rosenzweig, but the flooding damage we can. Partly due to global warming, sea level has climbed about a foot in the NYC area over the past century, giving storm surges a “step up” along the coast.

In 2011, global sea levels fell below the long-term trend of sea level rise, but as La Niña waned late in the year, global ocean levels began rising rapidly.

Except for some La Niña-cooled regions of the tropical Pacific and a few other cool spots, the upper ocean held more heat than average in 2011 in the Pacific, Atlantic, Indian, and Southern Oceans.

Climate scientist Anthony Janetos makes it clear that climate change isn't some future abstraction: real and substantial impacts on people's lives, the economy, the environment, and our valuable natural resources are already happening here in the United States.

 

In the 2011 Arctic Report Card, scientists report that the bright white surface of the Greenland Ice Sheet has grown less reflective. The darker surface absorbs more sunlight, accelerating melting.

The arrival of Hurricane Isabel in 2003 flooded the retirement home of a Chesapeake Bay couple. With sea level around the Chesapeake Bay rising faster than the global average, how are coastal residents planning for change?

Six managers of State Coastal Zone Programs and National Estuarine Research Reserves comment on their plans for adapting to climate change.

Along coasts, people are waking up to the need for adaptation to climate change. This article points the way to information for getting started.
