Re Snopes- perhaps you remember this?-
"On 4 February 2017, the British tabloid Mail on Sunday (and the Daily Mail‘s online site) published an article by David Rose — a longtime proponent of climate change conspiracy theories whose analyses the scientific community widely regards as flawed and deceptive — alleging that scientists at the National Oceanic and Atmospheric Administration (NOAA) used misleading data in order to rush publication of a groundbreaking climate study and thereby “dupe” world leaders:"

"This newspaper has learnt that NOAA has now decided that the sea dataset will have to be replaced and substantially revised just 18 months after it was issued, because it used unreliable methods which overstated the speed of warming. The revised data will show both lower temperatures and a slower rate in the recent warming trend.
The land temperature dataset used by the study was afflicted by devastating bugs in its software that rendered its findings ‘unstable’."
"A final, approved version has still not been issued."
http://www.dailymail.co.uk/sciencetech/article-4192182/World-leaders-duped-manip...Now nowhere in the Snopes piece does it address the fact that both the land and and sea datasets are unusable. Or that both need replacing. Instead they insist it was a mere oversight that the data wasn't archived. It makes no difference if the data wasn't archived if both datasets are faulty.
You would think that Snopes would address this very basic issue.
As for the Karl et al 2015 paper it has a self-admitted significance of 0.1. A good significance is 0.01, a reasonable one is 0.05. 0.1 is crap.
