New research shows that black and white Americans responded differently when exposed to a video presentation that described Hurricane Katrina and then blamed the botched relief efforts on one of two causes: either government incompetence or racism, because the majority of Katrina's victims were black.

Three years after Hurricane Katrina devastated parts of the Gulf Coast, a new survey conducted by the Harvard School of Public Health Project on the Public and Biological Security shows that one-third (34%) of those affected by the storm report they are very prepared if a major hurricane were to strike their communities in the next six months.

There are two ways in which cooperation is the theme of a paper published this week by Mark Alliegro and Mary Anne Alliegro, scientists at the Marine Biological Laboratory’s (MBL) Josephine Bay Paul Center.

More than 1,800 people perished in the wake of Hurricane Katrina in August 2005—the largest hurricane death toll in the United States since 1928. For the most vulnerable—the urban poor with little money, no transportation and limited resources—Katrina threatened to take everything.

New Orleans residents who lost their homes in Hurricane Katrina were over five times more likely to experience serious psychological distress a year after the disaster than those who did not.

As the city of New Orleans struggles to rebuild from the devastation of Hurricane Katrina, researchers are learning more about weather and climate and their impacts on society. Scientists from the National Center for Atmospheric Research (NCAR) and many other institutions will converge in New Orleans next week to present their latest findings at the annual meeting of the American Meteorological Society.

Violent protests broke out in New Orleans today, amidst allegations that the city's proposal to tear down public housing units damaged by Hurricane Katrina, is seeped in racism.

With the help of NASA satellite data, a research team has estimated that Hurricane Katrina killed or severely damaged 320 million large trees in Gulf Coast forests, which weakened the role the forests play in storing carbon from the atmosphere.

Despite strong initial efforts to support the mental health needs of students displaced by Hurricanes Katrina and Rita, many schools have not been able to fulfill students' mental health needs over the long term, according to a RAND Corporation study issued today.

Two years ago, UC Berkeley civil engineer Bob Bea made national headlines critiquing New Orleans' levees and flood control system that failed under the onslaught of Hurricane Katrina. Now he is equally damning about the reconstruction efforts by the U.S. Army Corps of Engineers to make the city safer.

The perceived neediness of Hurricane Katrina victims is a better determinant of charitable giving than the victims' race, according to study by Christina M. Fong, research scientist at Carnegie Mellon University, and Erzo F.P. Luttmer, associate professor at Harvard University's Kennedy School of Government. The paper was published this month by the National Bureau of Economic Research (NBER).

Atlantic basin, and the reported increases in recent decades in some hurricane intensity and duration measures in several basins have received considerable attention.
