NASA tells us we’re in trouble
In an incredible new visual, deterioration of our glaciers over the past 47 years can be seen.
Since 1890, the glaciers have been retreating, with only short periods of small advances, NASA said.
“The differences between 1990 (Landsat image from January 12) and 2017 (ASTER image from January 29) can be seen in the pair of images, that include the Mueller, Hooker and Tasman Glaciers, NASA wrote on its website.
“Notice the larger terminal lakes, the retreat of the ice free of moraine cover, and the higher moraine walls due to ice thinning. The images cover an area of 39 by 46 km, and are located at 43.7 degrees south, 170 degrees east.
“These images show Mueller, Hooker and Tasman glaciers on New Zealand’s South Island in January 1990 (left) and January 2017 (right). The 2017 image shows less snow cover (white to light gray) and larger lakes at the glaciers’ termini (blue).”
So the question is, why compare with 1970?
This, which Whaleoil highlighted at the time, is New Zealand research by New Zealand scientists.
A period where some of New Zealand’s glaciers grew bigger, while those worldwide were shrinking, was likely to have been due to a series of unusually of cold years, according to new research.
At least 58 New Zealand glaciers advanced between 1983 and 2008, with Franz Josef Glacier doing so almost continuously during this time.
Increased rainfall has previously been thought to be the reason.
But a study by Victoria University and Niwa scientists has found that regional climate variability was the likely explanation.
Lead author Associate Professor Andrew Mackintosh says the anomaly between what was happening in New Zealand and the trend overseas hadn’t been satisfactory explained.
So, as we wrote at the time, “In short, the weather has been the hottest yet cold, and glaciers have receded yet grown”.
Just exactly what is settled with this science?
And why do academics and scientists expect to communicate in public and not face any scrutiny?
