Chris Mooney, Washington Post: The climate change simulations that best capture current planetary conditions are also the ones that predict the most dire levels of human-driven warming. Under a high warming scenario in which large emissions continue throughout the century, the models as a whole give a mean warming of 4.3 degrees Celsius (or 7.74 degrees Fahrenheit), plus or minus 0.7 degrees Celsius, for the period between 2081 and 2100. But the best models gave an answer of 4.8 degrees Celsius (8.64 degrees Fahrenheit), plus or minus 0.4 degrees Celsius. Overall, the change amounted to bumping up the projected warming by about 15 percent.
