Will Canada’s invaluable collection of ice cores tens of thousands of years old survive a season of heated budget cuts? Nature News reports on an email appeal from a government glaciologist last week asking the Canadian research community to provide cold storage for the beleaguered collection in Canada’s Ice Core Research Laboratory. The cores have been collected throughout the Canadian Arctic in the past 40 years, including from ice caps and ice fields not represented in collections elsewhere. They comprise more than half a mile/1,000 meters of ice documenting up to 80,000 years of climate history. They’re rich with dust, gas bubbles, and chemical isotopes that reveal atmospheric and temperature conditions of past climates and past climate changes. No other lab in Canada is big enough to store them. Yet already researchers in the US—citing the collaborativeness of the Canadian researchers—are expressing their willingness to help.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily bluster—Mother Jones' journalism is driven by one simple question: Will America move closer to, or further from, justice and equity in the years to come?
