Antarctica is rising much faster than expected, revealing that the hot rock of the mantle hundreds of miles below the icy continent is flowing much faster than expected, and so rebounding quickly to the loss of glacial ice, researchers say.

In 2011, many places in Texas and Oklahoma recorded more than 100 days over 100 degrees. Heat and drought contributed to more than $10 billion in agricultural losses alone. "Communities are drying up", Texas rancher Kevin Igo says.
