Based on scientific data or models which are working.... Tell us how much that man made CO2 contributed to the warming you say we are seeing. a. what warming are you referencing. b. how do you determine the percentage. c. what models are you currently using and how have you validated them. if you cant answer those questions... you yourself know your a full of shit leftist drone.
That's arguing the merits like a gentleman. A few observations regarding the OP: It's rather impossible to say definitively how cold the current spring will rank since we are in the middle of the current spring season. March was colder than average in the US, and much colder than last March. However, Global March temperature average was the 10th warmest on record. http://www.ncdc.noaa.gov/sotc/global/2013/3
Anything coming out of NOAA or NASA these days has to be suspect. They've been caught manipulating data and taking action against dissenting scientists. They have an agenda that is apparent to all.

No, but I think your birth may have been.
LOL. I guess you didn't follow the links to see the data. It's all supported. So don't make me laugh.
Bingo. It's typical warped denier bullshit. First of all, anything from WUWT is not to be taken seriously. It's a propaganda site funded by big oil/coal interests and run by an unqualified hack. So I looked at the Physics Today article that pisspoor listed. All the article does is summarize some of the bullshit critiques from hacks like Roy Spencer. It make no determination of the validity of those allegations. This is typical of the hollow BS that deniers hang their hat on. In every case, once one looks past the headline the story has no substance or credibility. If a scientist could prove that AGW is wrong, that scientist would be rich and famous. There are no respected scientists that can do such a thing. The idea that both NASA and NOAA and all the rest of the world's climate organizations would, or even could, so manipulate the data of hundreds of sources, across multiple disciplines is something only a raving lunatic would consider likely. So of course pisspoor does.
You guys can't even look at the stories. Links are provided to the NOAA data and images showing the manipulation. Stop being so political and deal with the facts. AGW is a hoax and the government (liberals) are helping to perpetuate the lie.
