October 2014 was the warmest October on record, and the year-to-date-period January - October was Earth's warmest such period since record keeping began in 1880, said NOAA. They also rated the past 12 months--November 2013 through October 2014--as the warmest consecutive 12-month period among all months since records began in 1880; 2014 will be the warmest calendar year on record if global temperatures in November and December merely match their average values recorded since 2000.

As we discussed the report in class the message that emerged from the report is that if we do not reduce our carbon dioxide emissions by several 10s of percent, in the next 1 – 3 decades, then the warming and its impacts will become large enough that adaptation is not incremental; that is, adaptation will not, simply, be modifying what we know how to do. In some cases adaptation will not be possible – we will have to do something new, something different. It is also true that as the warming gets larger, we move outside of the range or parameters on which our models were trained. Therefore, model guidance becomes more unreliable
