Is there any possible natural reason for the entire globe to be .79 degrees warmer than last year?

This is from the UAH satellite data which Christy and Spencer assert is much more accurate than ground-based measurements and avoid Urban Heat Island distortions. The average global temperature at the surface level yesterday was .79 degrees warmer than the same date just a year ago. At this time last year we were in a El Nino pattern, now we are in a La Nina which is cooling the ocean surface, but the apparently warming of land is overwhelming that. The sun is still in a quiet period. .79 degrees in one year is a huge one-year increase (more than double the increase that the IPCC projected for each decade). I do understand that there is variation every year, but is there any possible natural reason for such extreme warming in one year especially considering that the strongest known natural variants would be contributing to cooling?
Even if some quirk in the data could explain the extreme increase on a specific date, is there a natural factor that could explain any warming versus last year?
Let's remember here: the sun has not done anything to increase temperatures, and the long run cycles are in a very slow cooling patterns. Those are not possible answers.
And this is the average of the entire world -- it is not weather in a particular place. This is the entire system.
Edward, are you aware the projections are only .2 degrees per decade? .79 degrees in a year is huge. 2-3 degrees in a decade would be catastophic. 2-3 degrees in one year is beyond imagination.
2-3 degrees in a century is the extremely rapid rate that is causing potentially catastrophic changes.
Corrected link. They've added a day and the difference is down to .75 degrees.
