Six months of 2014 (May, June, August, September, October, and December) were record warm, while April was second warmest, January, March, and July were fourth warmest for their respective months, and November was seventh warmest.
Overall, the global annual temperature has increased at an average rate of 0.06°C (0.11°F) per decade since 1880 and at an average rate of 0.16°C (0.28°F) per decade since 1970.
Top 10 Warmest Years (1880–2014)
The following table lists the global combined land and ocean annually-averaged temperature rank and anomaly for each of the 10 warmest years on record.

To conservative hippy. In a non warming world, you would expect roughly the same number of cool records to be set as there would be warm records, when averaged over an appropriate timescale. Here in Aus, and many if not most places around the world, the number of warm weather records per year greatly out numbers the cold temp records. Much of the warming in Aus is seen in increasing minimum nightly temperatures. Absolutely yes, we are warming our one and only world.

ConservativeHippie,

<<How could water from the sea possibly travel uphill under the full length of the glacier and then start melting the glacier from below?>>
It can't. The trouble is it wouldn't need to. Merely reaching the edge of the glacier would erode it more quickly. The higher the sea gets the worse the problem would be, particularly if there's fresh water below the glacier (as would happen if melting occurs on the top and water falls through the cracks) as then the sea at the edge of the glacier would slow the flow of that water, meaning there's more water under the glacier which would reduce the friction and so speed up the glacier's flow.

<<What is stopping this mystery/magical water from freezing when it makes contact with the glacier? >>
The glacier not being cold enough. I hope that clears up the mystery.

<<Aiden's description of the science causing the 'melting of the Artic' or Antarctic is a perfect example of Warmist logic. They quote "facts" with total disregard to common sense.>>
On the contrary, I'm showing far more common sense than you are. Your problem is you wrongly take "common sense" to mean "expectations", and you disregard facts that contradict it.

<<When we have an extra hot summer it's the proof of global warming but the opposite doesn't apply if we have an extra cold winter. Sun spots, the effects of La Nina and El Nino's or volcanic eruptions never mentioned as possible contributing factors effecting a change in climate.>>
Volcanic eruptions have a cooling effect. Sunspots have a small effect that seems to be diminishing. And El Niño and La Nina are the effects not the cause; global warming is expected to lead to more El Niño events.

Our hot summers are seemingly without precedent. When was the last time we could say the same about extra cold winters?

To runner, just find the statistics of hot weather caused deaths. Additional warming not a laughing matter. Also review the number of farmers in Bendigo, Shepparton district who have bulldozed fruit orchards because of fruit loss thru heatwaves.

To Spindoc,
Do you know why the sky is blue? It is the colourless oxygen and nitrogen gases in our atmosphere that temporarily grab blue light energy from the Suns light, then tosses it in all directions. Carbon dioxide does exactly the same thing with invisible IR heat energy heading out to space. Scattered in all directions, a proportion is sent back to earth, causing less heat loss at night, and consequent planetary warming. By the way, this science known by late 1890s - a long time ago. Some people take a long time to learn, or deliberately turn a blind eye.

Aiden, if the energy return is sufficient the amount of energy that
has to be input to the system is enormous with low eroei,
and it then becomes financially unviable.
Even if the input energy is free, you must take into account the
embedded energy and that is why solar and wind fail.
It cannot be escaped.
