In a bruising open letter to President Obama, the Massachusetts Institute of Technology is urging the administration to give up its bungled, politically-driven green energy program to focus exclusively on new taxes and industries aimed at fixing global warming.

“You have the power and the opportunity to lay the groundwork for a new clean-energy policy that will help us avoid the worst consequences of climate change,” said the letter, published in the MIT Technology Review. “It is quite possible that if this is not done over the next four years, it will be too late.”
