Greenland Ice Varies, Don’t Panic
Posted on 2 Days Ago by Ron Clutz
The scare du jour is about Greenland Ice Sheet (GIS) and how it will melt out and flood us all. It’s declared that GIS has passed its tipping point, and we are doomed. Typical is the Phys.org hysteria: Sea level rise quickens as Greenland ice sheet sheds record amount: “Greenland’s massive ice sheet saw a record net loss of 532 billion tonnes last year, raising red flags about accelerating sea level rise, according to new findings.â€
Panic is warranted only if you treat this as proof of an alarmist narrative and ignore the facts and context in which natural variation occurs. For starters, consider the last four years of GIS fluctuations reported by DMI and summarized in the eight graphs above. Note the noisy blue lines showing how the surface mass balance (SMB) changes its daily weight by 8 or 10 gigatonnes (Gt) around the baseline mean from 1981 to 2010. Note also the summer decrease between May and August each year before recovering to match or exceed the mean.
