From a comment in /r/climatechange/:<p>>The paper does not dispute there is a warming at some rate. What they want to determine using statistics is when the rate changes; as in, the change changing faster, or the change changing slower. Although the trend is warming, there is a lot of noise, random accelerations and braking, so they claim it is statistically difficult to pinpoint when the changing change changes.<p><a href="https://old.reddit.com/r/climatechange/comments/1g6vubd/a_recent_surge_in_global_warming_is_not/" rel="nofollow">https://old.reddit.com/r/climatechange/comments/1g6vubd/a_re...</a>
