Yesterday marked the deadline for nations to send their commitment letters to the U.N. and reaffirm the promises made at the Copenhagen Climate Conference. Perhaps surprisingly most of the nations turned their homework in on time. The letters outline various voluntary plans and pledges to cut carbon emissions but will these promises be enough to prevent the temperature from rising 2 degrees Celsius? Patt talks with the U.N.’s top climate adviser to Secretary-General Ban Ki-moon, Janos Pasztor about who is keeping good on their promises and if those promises are good enough.
