The Pentagon has taken few steps to prepare its overseas installations for climate change, a government watchdog said Wednesday. (From The Hill/ By Rebecca Kheel) -- “While the military services have begun to integrate climate change adaptation into installations’ plans and project designs, this integration has been limited,” the Government Accountability Office (GAO) said in a report [...]
Greenland (Credit: Matthew Cooper) A new UCLA-led study reinforces the importance of collaboration in assessing the effects of climate change. The research, published Dec. 5 in the journal Proceedings of the National Academy of Sciences, offers new insights about previously unknown factors affecting Greenland's melting ice sheet, and it could ultimately help scientists [...]

Climate change is real. It’s caused by greenhouse-gas pollution released by human industrial activity. Its consequences can already be felt across every region and coastline of the United States—and, unless we stop emitting greenhouse gases soon, those consequences will almost certainly get worse. Those are the headline findings of the Climate Science Special Report, a sweeping and more than 800-page examination of the evidence. The report was published Friday by four agencies of the U.S. government and academics from across the country.
Climate change could lead to sea level rises that are larger, and happen more rapidly, than previously thought, according to a trio of new studies that reflect mounting concerns about the stability of polar ice.
The east coast of the United States is slowly but steadily sinking into the sea. This is the result of a recent study which took a variety of factors into account when determining the continuous sinking of the eastern seaboard. This will result in more frequent and severe flooding events in the future as the sea encroaches upon coastal communities and homes. This is all the more relevant as Hurricane Irma inundates the southeast coastline with rising storm surge.
Sea-level rise isn’t just happening; it’s accelerating. And some areas of the United States—like Florida—are seeing “hot spots” where the ocean can creep up six times faster than average. Those are the findings of two new studies published yesterday, which have potentially troubling implications for urban planners trying to address sea-level rise. They also help explain why residents of Florida and North Carolina have seen sharp increases in coastal flooding in recent years.
In 2014, a team of researchers led by a paleobiologist from the University of Missouri found that clams from the Holocene Epoch (that began 11,700 years ago) contained clues about how sea level rise due to climate change could foreshadow a rise in parasitic trematodes, or flatworms. The team cautioned that the rise could lead to outbreaks in human infections if left unchecked. Now, an international team from Mizzou and the Universities of Bologna and Florida has found that rising seas could be detrimental to human health on a much shorter time scale. Findings from their study in northern Italy suggest that parasitic infections could increase in the next century, if history repeats itself.
The world saw headlines about one of the largest icebergs ever calved a few weeks ago. But a smaller one on the other end of the globe might have bigger consequences. The chunk of ice, which broke free in the Arctic last week, is more worrisome to climate scientists who are watching one of Earth's largest glaciers shed pieces in a way that stands to raise sea levels.
For nearly a century, the O'Shaughnessy seawall has held back the sand and seas of San Francisco's Ocean Beach. At work even longer: the Galveston seawall, built after America's deadliest hurricane in 1900 killed thousands in Texas. These are just two examples of how America's coasts -- particularly those with large urban populations -- have been armored with humanmade structures.
