The announcement by the U.S. and China was important for several reasons: Together they account for around 40 percent of global GHG emissions, according to the Union of Concerned Scientists; there had heretofore been few signs of a Chinese willingness to commit to capping emissions; and it raised hope that future global negotiations might actually yield an agreement to rein in emissions enough to keep the average global temperature from rising more than 2 degrees Celsius.

Christy is correct to note that the model average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence on global temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep oceans).
