Scientists detect seasonal pattern to glacial earthquakes in Greenland, see signs of increase
.... In contrast, non-glacial earthquakes in northern latitudes show no such seasonal variability. In addition, the number of glacial earthquakes in Greenland increased markedly between 1993 and 2005. Annual totals hovered between 6 and 15 through 2002, which was followed by sharp increases to 20 earthquakes in 2...Sociality of sweat bees evolved simultaneously during climate change

..."Global warming is expected to be enhanced at high latitudes and, for this reason, should be detected there first.
