Does any of this matter? Does any of this mean that climate change is not real, or the Greenland ice sheet is not melting six times faster since 2002, "
1) NASA has pointed out this is normal?
"Ice cores from Summit show that melting events of this type occur about once every 150 years on average. With the last one happening in 1889, this event is right on time," says Lora Koenig, a Goddard glaciologist and a member of the research team analyzing the satellite data."

2) That ice that's melting there? It grew in the 1950s and 1960s.
"In the early 1920s and 1930s, temperatures were high, similar to that of the present, and this affected the glacial melt. At the time many glaciers underwent a melt similar or even higher than what we have seen in the last ten years. When it became colder again in the 1950s and 1960s, glaciers actually started growing,"

3) What's interesting about the NASA news release is that the actual facts of the matter are that the ice is melting exactly on time with its 150 year cycle.
You'd expect in a warming world for this to be at least one day early. But it's not, so explain to me why it's on time in a world of "unprecedented" warming.
And if it's 150 year cycle and completely on time it's not exactly "unprecedented" melting - it happens every 150 years. Somebody tried to spin the fact the melt is normal with an alarmist headline that isn't true. Mann left NASA shortly after this and it never happened again. Fwiw.
4) Arctic sea ice has been growing for 3 continuous years. NASA data:

5) It's been hotter in the past. Much.

6) Busted. http://www.telegraph.co.uk/news/earth/environment/globalwarming/11395516/The-fiddling-with-temperature-data-is-the-biggest-science-scandal-ever.html
Since 1880 you mean, that's when we began recording temperature history. From the article you posted:
" Both NASA and NOAA reported that 2014 was the warmest year since global temperatures were first recorded in 1880. "
And FYI, that temperature rise is two one hundredths a degree more than 1998 which is smaller than the margin of error. http://data.giss.nasa.gov/gistemp/FAQ.html
Epsilon is larger than that, whychus why NASA,who collected this data, says there's been "no warming this century".
Also, it depends on what dataset you look at. Th eUK Met office doesn't say it's the hottest year and the RSS and UAH satellite data show 2014 was not even close to being the warmest on record http://cdn01.dailycaller.com/wp-content/uploads/2015/01/RSSUAHdata-620x457.png
NASA and the NOAA don't say it's been the warmest year, they speak in terms of probabilities. We'll know more when they've finished checking the data in March.

Also, the results won't be in until about March 2015 an there are more than one dataset and not all peg this as the hottest yer. Even if it is, it' one year. Out of no warming this century you'll need a few more hot years to actually change the averas, it could be a random outlier. Ref: Pof. Currey at gatech, testimony before the US Senate. I hope that's as authoritative enough a "Accuweather"; she was under oath.

Now, forget 1880, lets look back 2000 years.

Also this: http://rs79.vrx.net/opinions/ideas/climate/.images/HolocenePeriods.png
It was warmer in the 1300s and warmer still around 0AD and not just warmer but significantly warmer than now.
To illustrate this I put Mann's "hockey stick" graph on top of the Danish Tree ring data and normalized the x and Y axes.It shows at a glance how much warmer it used to be:

So one cannot say with any authority 2014 was the first year. And that's not an answer to the question "why didn't is get any warmer as the CO2 rose sharply" as you can plainly see the period 2000-2010 is a flatline if you draw a line through the curve.
