The New Little Ice Age Can Start in Montana
MONTANA — June 14, 2018
A strong cold front moved at the end of Saturday, lowering temperatures in most areas as much as 30 degrees below normal on Sunday, and on Monday in some areas the temperature fell below the freezing mark.
People said about big snow which was at the resort of Showdown in the mountains of little belt.
An unusual snowball has also been falling at the Big Sky resort South of Bozeman and along the Beartooth pass on the Montana-Wyoming border.
Finally, with regard to the advancement of the Ice Age, there are at least 17 cycles between glacial and interglacial periods. In all times they lasted longer than usual. The last was about 100,000 years ago and lasted until 25,000 years ago. Today we are in a warm interglacial period as for during the most intense part of the last Ice Age.
Nowadays a small changes in insolation driven by changes in the Earth’s orbit can push the planet into or out of an ice age through the planet’s “climate feedback” mechanisms.
But in this case the greenhouse gases have an important role in controlling climate. In particular, atmospheric carbon dioxide has to be low enough for the planet to start cooling before it could tip into an ice age.
"Now one idea is that small increases in greenhouse gases due to the expansion of agriculture that started 8,000 years ago have in fact delayed the next ice age. What’s more, if we continue emitting greenhouse gases at the same rate, we might have put off the next ice age for at least 500,000 years," say American scientists.
