Sea level rise rate for 2009-2010
March 23, 2015

The coastal sea levels along the Northeast Coast of North America show significant year-to-year fluctuations in a general upward trend. Analysis of long-term tide gauge records along the North American east coast identified an extreme sea-level rise event during 2009–2010. Within this relatively brief two-year period, coastal sea levels north of New York City jumped by up to 128 mm.

Hurricane frequency in model runs
February 2, 2015

Climate extremes such as hurricanes and typhoons can cause death and destruction for communities around the world. Scientists are interested in studying both the predictability and possible future changes in the frequency and intensity of such storms.

Hurricane storm track

Tropical cyclones are among the most devastating storms on Earth. Tropical cyclone activity in the North Atlantic displays large interannual variability in both number and track density. Recent studies show that global high-resolution models have remarkable skill in simulating the interannual variability in cyclone counts, implicating strong control by sea surface temperatures patterns.

To understand the increased number of cold extreme events in recent years, a study conducted by an international team of US and Korean scientists suggests that the recently drastic reduction of Arctic sea ice cover could be the key driver.

Two color graphs
November 3, 2014

Researchers investigated the response of Atlantic Meridional Overturning Circulation (AMOC) to the rise of atmospheric CO2 in the NCAR Climate System Model version 3, with the focus on the different responses under modern and glacial periods.
