The Version 6.0 global average lower tropospheric temperature (LT) anomaly for October, 2021 was +0.37 deg. C, up from the September, 2021 value of +0.25 deg. C.
The linear warming trend since January, 1979 is +0.14 C/decade (+0.12 C/decade over the global-averaged oceans, and +0.18 C/decade over global-averaged land).
The UK is mourning the melt of its longest-running snow patch, dubbed the “Sphinx.”
The occasion marks only the eighth time the frosty mound has fully disappeared during the past 170 years or more, according to experts. The Sphinx’s previous melts occurred in 1933, 1959, 1996, 2003, 2006, 2017 and 2018. Prior to ’33, it is believed to have endured at least since the 1700s.
In recent weeks, the parcel of snow, located on the Braeriach mountain in the Cairngorms range of Scotland, had shrunk to about the size of a piece of letter paper, approximately 8-by 11-inches. It’s nestled in a hollow which they call Garbh Choire Mor, formed by a glacier during the previous ice age — once thought to be Scotland’s snowiest mountain nook, even during the summer.
Increasingly warmer weather due to climate change “seemed to be the logical” explanation, said Cameron — a trend also seen elsewhere in the region.
“What we are seeing from research are smaller and fewer patches of snow,” he said. “Less snow is falling now in winter than in the 1980s and even the 1990s.”
Snow has fallen less and less frequently since the 1980s, according to Cameron’s own research, commissioned last year by the Cairngorms National Park Authority. Findings suggest that by the 2080s, there may be little to no snow at all on the mountains.
