OK, first off - do you understand what that graph is showing? It's showing temperature anomaly - ie departure from normal. Meaning it takes a reference year range for an average temperature, and plots how much the current year varies from that. Since it has a reference range that is relatively recent (ie it includes much of the recent severe warming), some of it shows "cooling". But, that's ok. Second. do you understand what the fact that most of the data points on that graph are above 0 means? That means that the vast majority of temperatures since 2005 are above the reference mean - meaning it was hot. The fact that any given year within that range is less than another is meaningless. Third, and most importantly, is the range we're looking at. Let's look at another graph:
Its reference range is 1961 to 1990, and its plotted range is 30 years, instead of 13 like in your graph. Notice the upward trend - and again, these are anomalies, or departures from normal, not absolute temperatures.
Finally, let's look at another graph:
This again shows the temperature anomaly, again with a reference range of 1961 to 1990, but with a whopping 11,300 year span. Notice the slight (that's sarcasm) upward trend at the end. That's the current situation. What we can glean from that is that it's getting pretty f*&king hot pretty f*&king fast. Here's a blurb from the associated article for that graph:
Natural variability can explain much of the temperature variation since the end of the last ice age, resulting from factors such as changes in the tilt of the Earth's axis. Over the past century, though, global average temperatures have "risen from near the coldest to the warmest levels" in the past 11,300 years, the 2013 study authors explain. Over this same period, emissions of heat-trapping gases from human activities have increased.

So, yeah, whoopy - you take a graph from the last 13 years and plot 2 Xes on it and, wow, the more recent is lower than the other. Big f-ing deal. The fact is that the earth is warming more in a shorter time period than it ever has, and it's mainly because of man-produced greenhouse gases. Deal with it.
Now comes the real shocker. This improper normalization procedure tends to emphasize any data that do have the hockey stick shape, and to suppress all data that do not. To demonstrate this effect, McIntyre and McKitrick created some meaningless test data that had, on average, no trends. This method of generating random data is called Monte Carlo analysis, after the famous casino, and it is widely used in statistical analysis to test procedures. When McIntyre and McKitrick fed these random data into the Mann procedure, out popped a hockey stick shape!
The main author, Micheal Mann, has been discredited. He used a rigged statistical analysis to produce the hockey stick.
When fed random data sets, the computer program spits out hockey sticks like clockwork.

CALL me a converted skeptic. Three years ago I identified problems in previous climate studies that, in my mind, threw doubt on the very existence of global warming. Last year, following an intensive research effort involving a dozen scientists, I concluded that global warming was real and that the prior estimates of the rate of warming were correct. I’m now going a step further: Humans are almost entirely the cause.

It's .6 degrees C.
Seems like this could be a natural cycle and we are going to go slightly up in temp and slightly down.

If you say Ball is incorrect, then we could look for a third option. I wouldn't accept Mann's work though.

word is natural cycles displace temperature around, they say the oceans are absorbing the equivalent of multiple atomic bombs of energy each and every single second, and heating up all across, impeding a lot of the potential warm up from showing due to the high specific heat of water(water can absorb lots of heat before changing one degree).
