Temperature in Greenland
Hi Everyone.
I think many
of you have heard about this big news – temperature rising in Greenland causes Greenland
ice sheets melt very quickly, and the melt in the summer 2012 could be the
fastest on records! Oh my god!!! What does it mean? What is the world telling
us? Will it be dangerous? And what does the ice melt imply the situation of
today’s Earth climate?
Recent studies
show that the weird conditions of temperature rising is Greenland are not
caused by external variability or ‘anthropogenic warming’, but from internal
variability of the climate system itself. Kobashi et al. (2011) explained the trend
of temperature in Greenland as follows;
“The Greenland temperature
trend diverges from the global trend in the last 168 years, which raises the
possibility that much of the trend is due to natural variability, not the
recent warming owing to increasing anthropogenic greenhouse gases in the
atmosphere” (cited in Kobashi et al., 2011: L21501).
Besides, Chylek et al.
(2006) observed temperatures from eight stations in Greenland and found that
although the temperatures considerably increased in the past decade, compared
to 1920s-1930s when the temperatures were higher, it represents that present Greenland
temperature is colder.

Report, 16 October 2007 |
So, now we can relieve (at least for a while) that the variation of
temperature in Greenland is not implying anything bad. However, further studies
are required and we still have to carefully observe from the records and see the
future trend of Greenland temperature which can be more abnormally fluctuant.
Who knows???
