Skiers have as much to lose as anyone. Glaciers are shrinking everywhere, overall there is less snow and winters are getting shorter at both ends, but especially in the spring. In a groundbreaking 2013 study, the U.S. Geological study found a 20 percent decline in Rocky Mountain snow cover since 1980.
Another research paper published just this year in meticulous Swiss fashion documented that the snow season has shortened by 37 days since 1970, with a 25 percent decline in the average maximum snow depth across the entire Swiss Alps, at all elevations. The researchers were surprised to find the decline even at the higher mountain weather stations close to famous resorts like Zermatt and Davos.
In another Christmas-themed story, I reported on a Norwegian study that showed how widespread grazing by reindeer affects the reflectivity in northern tundra regions. It turns out that when the ungulates munch shrubs and brush, they make the world cooler: Save the Reindeer, Save the Arctic.
Another sign that we may be near a climate tipping point is research from California showing that some severely burned forests just aren’t regenerating at all. The fires have become so big and so intense that all the seed stock trees are destroyed, leaving big cleared areas where there is no source for new growth — except for shrubs and brush that quickly grow to dominate the landscape and prevent new seedlings from taking root: California Forests Failing to Regrow After Intense Wildfires.
And some people think that they don’t have to worry about climate change because they heard global warming slowed down between 1998 and 2012. Not so, according to scientists who recalculated the rate of warming in the world’s oceans to show there was no hiatus: Already Debunked Global Warming ‘Hiatus’ Gets Another Dunking.
New Yale study shows funding behind the effort to mislead Americans on climate science
By Bob Berwyn
Organizations funded by ExxonMobil and the Koch brothers form the core of a disinformation network that has spawned a vast body of literature that deliberately tries to deceive the public about global warming, according to a new study published in the Proceedings of the National Academy of Science.
The research by Yale University researcher Dr. Justin Farrell closely scoured more than 40,000 texts produced by the climate change counter-movement (164 organizations), finding that organizations with corporate funding were more likely to have written and disseminated texts meant to polarize the climate change issue.

‘When it comes to climate change, scientists are people, too …’
The consensus on the reality of climate change extends beyond the field of climate science to other disciplines, according to a new study out of Purdue University, where researchers surveyed 700 scientists.
‘We should no longer accept the claim that there is warming missing higher in the atmosphere’
FRISCO — Decades of readings from thousands of measuring stations around the world show in excruciating detail how the Earth is warming under its thickening blanket of greenhouse gases, but tracking the temperature rise in the upper levels of the atmosphere has been more elusive.
But new research by Australian climate scientists, published in Environmental Research Letters, confirms strong warming in the upper troposphere, crushing yet another argument used by science-denying global warming skeptics who try to cast doubt on the overwhelming evidence of dangerous climate change.
FRISCO — Some of the world’s leading scientists say it’s time to get serious and take bold action now to ensure completion of an effective climate treaty this year.
Banding together as the Earth League, the scientists released a statement spelling out what’s needed to give the world a good chance of avoiding dangerous climate change. The first essential element is a commitment to limit global warming to below 2 degrees Celsius, which requires transition to a zero-carbon society by mid-century.
FRISCO — Debates about global warming can quickly descend into murky territory, especially if they take place in a political context. But communities looking for straightforward and nonpartisan scientific information can find from a science speakers network that includes climate experts from all 50 states.
