The Earth's wettest regions are likely to get wetter while the most arid will get drier due to warming of the atmosphere caused by increased levels of carbon dioxide, according to a new NASA analysis of more than a dozen climate models.
Superstorm Sandy pummeled the East Coast six months ago, and, as with other natural disasters, the Federal Emergency Management Agency was there from day one, finding people temporary shelter and later supporting rebuilding efforts.
FEMA also has a lesser-known role. It oversees the creation of flood maps, which model the risk of flooding in different areas during storms. These maps are also used to set building codes and flood insurance rates. In New York and New Jersey, FEMA is updating those maps, and so far many homeowners don't like what they are seeing.
