2014 will be the hottest year on record

According to data from NOAA, 2014 is sure to set a new temperature record
For those of us fixated on whether 2014 will be the hottest year on record, the results are in. At least, we know enough that we can make the call. According the global data from NOAA, 2014 will be the hottest year ever recorded.
I can make this pronouncement even before the end of the year because each month, I collect daily global average temperatures. So far, December is running about 0.5°C above the average. The climate and weather models predict that the next week will be about 0.75°C above average. This means, December will come in around 0.6°C above average. Are these daily values accurate? Well the last two months they have been within 0.05°C of the final official results.
What does this all mean? Well, when I combine December with the year-to-date as officially reported, I predict the annual temperature anomaly will be 0.674°C. This beats the prior record by 0.024°C. That is a big margin in terms of global temperatures.
For those of us who are not fixated on whether any individual year is a record but are more concerned with trends, this year is still important. Particularly because according to those who deny the basic physics and our understanding of climate change, this year wasn’t supposed to be particularly warm.
For those who thought that climate change was “natural” and driven by ocean currents, this has been a tough year. For instance, using NOAA standards, this year didn’t even have an El Niño. NOAA defines an El Niño as 5 continuous/overlapping 3-month time periods wherein a particular region in the Pacific has temperatures elevated more than 0.5oC.
Interestingly, we are currently close to an El Niño, and if current patterns continue for a few weeks, an official El Niño will be announced. But it hasn’t been yet, and if we do get an El Niño, it will affect next year more than this year. How could the hottest year have occurred then, when the cards are not stacked in its favor? The obvious and correct answer is, because of continued emission of greenhouse gases.
