Since I am not a scientist, perhaps one of you fear mongers can explain this to me....
According to this data... 2009 is NOT the warmest year on record as the article Dung posted states.
Also, why are they using 1951-1980 as the 'base' period?
Also, why did NASA admit 1934 was the warmest year on record (this was stated before 2009), when the data on here does not seem to show that?
Also, why does Hansen continue to block FOIA requests for the raw data?
I think you're confused. It's probably because you read rightwing blogs for science information.
1934 was a record hot year....in the United States. But that's not pertinent to global warming, is it?
This is what the rightwing blogs are referring to, when they mislead about 1934. Notice, this is the NCDC for united states temperatures.

And that's got nothing to do with global temperatures. Furthermore, land temperatures are not at all the most salient metric. Ocean temperatures are. Oceans actually control the climate, not land. And ocean temperatures have been rapidly accelerating, far more than land temperatures.
Regarding 2009.....2009 was the second hottest year globally, after 2005. Maybe dung or whoever it was, should apologize for being off by one year.
As for the baseline, that's probably something that is explained if you read the actual studies methodology section. I'm sure it's published on the internet, and easily accessible. I doubt anyone has time here to research it for you. I don't know anything about Hansen and FOIA, except that Tinfoil never posts anything about this crap unless it comes from a partisan rightwing blog. Which aren't reliable sources of scientific information. I suggest you check factcheck.org, who totally debunked "climategate", and maybe Hansen himself has put out a statement.
Regardless, these amount to nothing more than distractions, and the smart people who write the rightwing blogs you and tinfoil read, are deliberately misleading you. Every reputable scientific body and organization on the planet with expertise in climate science agrees that there is a high probability than humans are impacting the climate. I've been asking for years for denialists to present on single major reputable scientific organization having expertise in climate science, who concurs that humans aren't affecting the climate. And for like four years, the rightwing denialists haven't been able to give me one.
EDIT:
I went ahead and looked at the methodology for using the 1951-1980 baseline.
Really, it took like 5 minutes to find it. There's no grand conspiracy of evil liberal scientists to hide information. If ya'll would get of the rightwing blogs, this information is easily accessible to the public.
Here's the reason for using a 1951-1980 baseline. And it makes total sense to me, as it would to anyone with a rudimentary science background.
Anomalies and Absolute Temperatures
Our analysis concerns only temperature anomalies, not absolute temperature. Temperature anomalies are computed relative to the base period 1951-1980. The reason to work with anomalies, rather than absolute temperature is that absolute temperature varies markedly in short distances, while monthly or annual temperature anomalies are representative of a much larger region. Indeed, we have shown (Hansen and Lebedeff, 1987) that temperature anomalies are strongly correlated out to distances of the order of 1000 km. For a more detailed discussion, see The Elusive Absolute Surface Air Temperature.
