As Louisiana Floods, Measuring the Climate Change Effect

The heavy rains and flooding in Louisiana have been devastating. Can we attribute the severity of it to climate change? How you measure that depends on the questions you ask.

Construction in the Swamp

Despite the miserable weather and ongoing rain, we constructed a wooden structure to hold the GPS receivers, solar panels and other electronic equipment between the three wells. We worked out how and where to mount the antennas and had parts made to accomplish it. Although I had to leave before it was completed, the team persevered through the storm and now we will be monitoring ground subsidence and sediment compaction in the Mississippi Delta.

Visit to a Different Delta: the Mississippi

This summer I am in the Mississippi Delta in southern Louisiana helping to install an updated version of the compaction meters that we have in Bangladesh. The environment is quite different and we have arrived in the midst of an historic storm. Luckily for us the brunt of the storm is NW of us. So far, we are still able to work between the rain above and the mud below.

Climate and Cod

A new study finds that the climatological phenomenon known as the North Atlantic Oscillation contributes to fluctuations in the cod population off the New England coast, and could help fishery managers protect the population from future collapse.

For Climate Change, Carbon Pricing is No Silver Bullet

Many economists and policy experts believe carbon pricing is the most effective way to deal with global warming. But others argue that carbon pricing is not a silver bullet for dealing with climate change. Here’s why.

Study Warns of Surge in Heat-Related Deaths in New York City

A new study projects that as many as 3,331 people a year could be dying from the heat during New York City summers by 2080 as a result of the warming climate. That compares to 638 heat-related deaths on average between 2000 and 2006.

Wind-Blown Antarctic Sea Ice Helps Drive Ocean Circulation

Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.
