Some of the rhetoric around AGW denial/skepticism is that the Earth hasn't warmed in 10/16/17 years.

For example:

While this might be misleading the context of the larger trend etc, I'm wondering specifically about this claim, and what it relates to.

    It's worth mentioning in addition to the linked duplicate that the "No warming" claim only refers to surface temperatures which represent roughly 2% of the heat being accumulated on Earth. There has been no slow down in the oceans where 90% of the heat ends up. It also ignores the melting of ice, which represents a significant amount of heat with no temperature change. There has been some suspicion raised regarding this particular graph, which shows precisely a 0.00°C trend, that maybe some of the data has been fudged.

  • Just to add, the chart above, while accurate for RSS, is selectively chosen to show little warming. RSS chart from Wikipedia: en.wikipedia.org/wiki/File:Satellite_Temperatures.png and direct from the RSS website, remss.com images.remss.com/msu/msu_time_series.html RSS incorporates higher atmosphere temperatures into their models, not just surface temperatures. That's the main difference.

    1998 was freakishly hot year. If graph started just few years before that, trend would be substantially more obvious. That is exactly the reason why climate deniers start with 1998. Commented Jun 27, 2016 at 20:31
