The models say that Greenland should be getting warmer. But the data shows that Greenland is getting cooler.
But the scientists are urging everyone to go with the models and not the measured data.
We are living in crazy times when “scientists” say to disbelieve the data and believe their computer models instead.
Greenland’s recent temperature drop does not disprove global warming

Unfortunately, the planet is still getting warmer.
By: Charlotte Price PerssonUsing satellite data, a group of scientists has studied the development of temperature over the past 15 years in a large part of Greenland.
More precisely, they looked at surface temperatures (the temperature close to the Earth’s surface) in a part of the country that is not covered by ice—around one fifth of the surface area of Greenland.
Intuitively, you may think that temperature throughout all of Greenland has been increasing, but that is not the case. When you look at the yearly average, the ice-free parts of Greenland show a slight drop in temperature between 2001 and 2015. With swings in temperature from year to year.
However, these results should not be interpreted as “proof” that the Earth is not warming, say the scientists behind the research, which is published in the journal Scientific Reports.
This is weather, not climate
You need to have thirty years’ worth of data before you can “talk about climate,” says Professor Bo Elberling, an environmental geochemist and senior scientist on the study.
So we should be wary of discussing these results in the context of climate change, says Elberling, who is head of the Center for Permafrost (CENPERM) at the Department of Geosciences and Natural Resource Management at the University of Copenhagen, Denmark.
“What’s interesting here is that with these new data we have a unique description of the spatial distribution of surface temperatures across the entire ice-free part of Greenland, which we couldn’t pull out of the approximately 45 weather stations that cover Greenland today,” he says.

Global warming is real
Professor Michael Tjernström, a meteorologist from Stockholm University, Sweden, agrees with this assessment.
The time series is too short to say anything about climate trends, he writes in an email to our sister site,Videnskab.dk.
“Give me a specific location and a short time series and you could get almost any trend. Over a large area and over longer time I’m sure Greenland is warming,” writes Tjernström, who was not involved in the study.
The results should be seen as a part of the natural swings in climate. While you might find a small drop in temperature at individual locations, the overall development is in one direction, he writes.
All scientists interviewed for this article agreed that the new study does not question the inescapable reality that the planet is getting warmer.
