The more recent graphs https://sites.uci.edu/zlabe/arctic-sea-ice-extentconcentration/ https://sites.uci.edu/zlabe/arctic-sea-ice-extentconcentrati... (linked to in that tweet) look less immediately alarming (this year is no longer an outlier), but the general trend is still perfectly clear.
- halfdan 6y agoTwo standard deviations from the mean is an outlier.
- penteract 6y agoIt's an outlier if you assume nothing's changing, but there are better ways to say that sea ice is generally shrinking than by pointing out that the current year is an outlier. I meant that it doesn't look like an outlier if you assume arctic sea ice is decreasing (linearly?) over time (it does look like an outlier even there if you focus on October 24th).
