Not a website for me Here I find 15 hours above 0 C during that time: ftp://aftp.cmdl.noaa.gov/data/meteorology/in-situ/sum/met_sum_insitu_1_obop_hour_2019.txt == News elsewhere mentions 11 billion tons Greenland ice loss on one day (2019 Aug 1). So I mention conversion factor we are supposed to have handy. One millimeter sea level (rise) equals 364 billion tons of ice (melt).
