Ice cores don't give accurate temperatures. Not all data is equal.
2014 is only one year. If I cherry picked a year that was colder you would scoff at me. Why should I pay a ...[text shortened]... had it would not prove global warming is a bad thing. People can adapt to it. It is no big deal.

Where did I do that? Please show exactly where....
The temperature measurements made by people long ago after 135 years ago are an accurate enough indicator of global temperatures.
I dismissed temperature measurements made by people long ago
before 135 years ago at being reliable but pointed to other sources of data that does reliably indicate temperature BEFORE 135 years ago.

No, there is nothing flawed about the way they are using data here and using a combination of different sources of data to avoid gaps is perfectly sound and scientific and we scientists do this often. Using one source of data that is reliable for before 135 years ago and another that is reliable for after 135 years ago but not before thus the first data source covers where the second data source doesn’t is valid and is just fine and you just dismiss both because what it shows is that you are wrong.
Ice cores don't give accurate temperatures.
And, you not being an expert on this of course and haven't done a science degree on it unlike the people that have and know vastly more about it than you and I do, you know this how? Every measurement has what is called an error of measurement no matter how accurate it actually is thus to simply say it “don't give accurate temperatures” is meaningless -“accurate” by exactly how much? Within 1C? 0.1? 0.001C? Would you call within 0.001C “inaccurate” just because you don't like what it proves? The scientists that know vastly more about it than you do would have actually mathematically calculated this error of measurement and found that it still gives a very high probability that last year was the hottest year for the last few thousand years and certainly the hottest for the last 135 years. You haven't taken this mathematical calculation into account because you don't even understand the mathematics of error of measurement.
Please show your mathematical calculation complete with the right equations for error of measurement of the data to show exactly where the scientists that have done the maths of the ice core data analysis have made their maths error ....
2014 is only one year.
DIRR, It was not only “one year” but LAST year. With all else being equal, this being the warmest year indicates a warming trend.
If I cherry picked a year that was colder
can you "cherry pick" last year as being the colder year? Go on, try and do that.
Why should I pay attention to one year in the last 10?
why “10”? The last 10 years are part of the last 135 years.
Why should you pay attention to the temperature the last year of the last 135 years? -because that was the warmest year.
How much have temps increased in the past 10 years? Not much.
again, why the arbitrary choice of 10? the last 10 years have been the warmest amongst the last few decades -why ignore that just because you don't like what it implies? What about the temperature increase in the last 135 years? Why dismiss that just because you don't like what it proves?
And as for the "Not much" you say above; the global temperature doesn't have to increase by 'much" (just ~0.5C ) for this to cause a significant increase in frequency in extreme whether events (drought, floods, hurricanes, etc ) that cause deaths and costly damage.
