More evidence that there is nothing particularly alarming about climate change today
Some pictures of Greenland taken in the 1930s have revealed glacier melt that is worse than that taking place today:
Recently unearthed photographs taken by Danish explorers in the 1930s show glaciers in Greenland retreating faster than they are today, according to researchers.
The photos in question were taken by the seventh Thule Expedition to Greenland led by Dr Knud Rasmussen in 1932. The explorers were equipped with a seaplane, which they used to take aerial snaps of glaciers along the Arctic island’s coasts.
It’s difficult to know exactly what’s happening to the Greenland ice in total and very different estimates have been produced in recent times. However Professor Box says that many glaciers along the coasts have started retreating in the past decade.
It now appears that the glaciers were retreating even faster eighty years ago: but nobody worried about it, and the ice subsequently came back again.
The emphasized line is priceless. Chicken Little stayed home.
Why were the glaciers on Greenland retreating faster 80 years ago?
[One scientist, Professor Jason] Box, theorises that this is likely to be because of sulphur pollution released into the atmosphere by humans, especially by burning coal and fuel oils. This is known to have a cooling effect.
Unfortunately atmospheric sulphur emissions also cause other things such as acid rain, and as a result rich Western nations cracked down on sulphates in the 1960s. Prof Box believes that this led to warming from the 1970s onward, which has now led to the glaciers retreating since around 2000.
Or, “we cleaned up the air and it got warmer”. Other scientists disagree:
Still other scientists, differing with Prof Box, offer another picture altogether of Arctic temperatures, in which there were peaks both in the 1930s and 1950s and cooling until the 1990s: and in which the warming trend which resulted in the melting seen by Rasmussen’s expedition actually started as early as 1840, before the industrial revolution and human-driven carbon emission had even got rolling. In that scenario, variations in the Sun seem to have much more weight than is generally accepted by today’s climatologists.
Variations in the Sun! Whoda thunk?
Bottom line – nothing particularly unusual or worrisome if you actually have come to the conclusion, based on the evidence at hand, that the earth goes through climate cycles. The key, of course is the fact that a warming trend that resulted in the retreat of the glaciers in the 1930s was begun almost 100 years before without the benefit of the industrial revolution and human carbon emissions.
Then there’s that lingering little scientific fact that CO2 is a lagging indicator, not a cause, of warming. The fact the alarmist side continues to love to ignore.
Anyway a little context to the “OMG the glaciers are melting”.
