Remember all the news ‘hottest day in 125000 yrs’?

During one of such previous 4 interglacial periods — when *annual* global temperatures were lower than today, at least one corner of Greenland was melted - enough to raise global seas by ~½ meter.

The GreenDrill project #LDEO #Columbia uses Cosmogenic Isotopes (like Carbon-14, here Beryllium-10) to determine when parts of Greenland were ice free.
