the second graph shown in that denialist video says nothing about arctic sea ice in the way the NOAA data do, which go back only to 1979. They are data about ice anomalies, not ice coverage. Also, I can't find a source for that second, allegedly IPCC graph, so it may be as fraudulent as the video's argument.

NOAA data goes back to the early 1970s. The IPCC paper can be found after a fairly trivial Google search here: https://web.archive.org/web/20120428072521/https://www.ipcc.ch/ipccreports/far/wg_I/ipcc_far_wg_I_chapter_07.pdf https://web.archive.org/web/20120428072521/https://www.ipcc.... Good. So let's summarize: - someone who disagrees with you can be called names - you're ignorant of the history of NOAA - if you can't find something, then the other person is a fraud - but you claim they make fraudulent arguments anyway so that's OK Very scientific.

  You are still cherrypicking by concentrating on these data, which are not conclusive. /so, you show me part of an in-depth paper saying that there were data before 1979 .It appears there might. However, in the paper, it says there was not much variance in sea ice significantly between the 1953 and 1984, but that 1960-80 was significantly colder anomaly period. (pp 224-5). But after that... much decline. None of what you talk about it particularly relevant, given ALL the other data about melting glaciers and sea ice extents since 1990, which you carefully ignore. Look here, for example https://sites.google.com/site/arcticseaicegraphs/longterm https://sites.google.com/site/arcticseaicegraphs/longterm

    If you're living in the US, you could of course just look outside and notice that you've just had the coldest October-April period on record. But yeah, the Arctic is clearly melting.

      Anyone reading HN should understand about variance in data sets. Given you're stooping to the level of 'It's cold at the moment, at this one data point', I cannot take your conversation seriously. You can do better, and you know it.
