Note that your posted chart corresponds nicely with the last several decades of intense solar activity.
Solar activity (as seen below in Cycle #24) has been diminishing recently and ice has been increasing.
If there is any mechanism of linking sun spots to global temperatures, it has to be through changes in in solar energy.
Unfortunately for you, solar energy has been going in the opposite direction of global temperatures -
so what is the mechanism of sun spots influencing global temperatures? Is it that they reduce the amount of horsepoo of the invisible magic ponies that encircle the planet?
One would think that even less pooping by your invisible magic ponies encircling the planet would still have a greater impact on upper atmosphere temperatures, which have actually remain relatively stable while the lower atmosphere, land surface temperatures and especially ocean temperature are all cooking - which is exactly what would be expected from CO2-related warming.
Here's a host of links that debunk the sun spot mythology -

My favorite is the one that shows a better correlation between sunspot activity and the number of GOP critters in the US Senate -

Fun with Correlations!
I guess your chart of decrease in sunspots at least provides some hope for the 2016 elections
This map outlines the median ice coverage since solar activity began to increase since 1981.
We've already debunked this cherry picking obfuscation. Here's a new word for you -
'Derp', noun - the constant, repetitive reiteration of an opinion that preceded evidence.
'Derpy', adjective - prior assumptions are so unwarrantedly strong that they are unaffected by evidence

The Conversion of a Climate-Change Skeptic
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.
My total turnaround, in such a short time, is the result of careful and objective analysis by the Berkeley Earth Surface Temperature project, which I founded with my daughter Elizabeth. Our results show that the average temperature of the earth’s land has risen by two and a half degrees Fahrenheit over the past 250 years, including an increase of one and a half degrees over the most recent 50 years. Moreover, it appears likely that essentially all of this increase results from the human emission of greenhouse gases.
Sure, there's still some tiny wiggle room that the warming is not anthropogenic, but only the most derpy cling to their false faith that warming isn't occurring with its subsequent consequences of ice melt and sea level rise. You're going to have a lot of explaining to do with your grandchildren - at least the ones that can tread water for hours.
