And then there is this—
Based on observation-initialized weather model runs by DMI, almost 12% of the Greenland ice sheet had more than 1mm of melt on Monday 11 April, following an early start to melting the previous day.
Scientists at DMI were at first incredulous due to the early date.
"We had to check that our models were still working properly" said Peter Langen, a climate scientist at DMI. “Fortunately we could see from the PROMICE.dk stations on the ice sheet that it had been well above melting, even above 10 °C. This helped to explain the results”. The former top 3 earliest dates for a melt area larger than 10% were previously all in May (May 5, 2010, May 8, 1990, May 8, 2006).
"Even weather stations quite high up on the ice sheet observed very high temperatures on Monday", said Robert Fausto, a scientist at GEUS who maintains PROMICE.dk melt data.
"At KAN_U for example, a site at 1840 m above sea level, we observed a maximum temperature of 3.1°C. This would be a warm day in July, never mind April." Other PROMICE stations in the network at lower levels had daily average temperatures between 5 and 10 °C.
And NOAA finally re-scaled this graph, but they're running out of room again. These lazy scientists need to get with the program.
Have a nice weekend.
