A small group of Canadian and Danish scientists have been drilling deep into the ice on Axel Heiberg Island, on the western edge of the Arctic Ocean. Ice core scientist Alison Criscitiello explains why drilling into the ice cap can give us a glimpse into the Earth’s past.

Drilling into Arctic ice to spy 20,000 years into the past

Three stories to expand your worldview, delivered daily. Matt Galloway cuts through a sea of choice to bring you stories that transcend the news cycle. Conversations with big thinkers, household names, and people living the news. An antidote to algorithms that cater to what you already know — and a meeting place for diverse perspectives. In its 20 years, the Current has become a go-to place for stories that shape and entertain us. Released daily, Monday to Friday. Some of the topics we’ve covered recently, include: the results of the Canadian Federal election — a minority Liberal government — and Canada’s new Prime Minister-elect Mark Carney. Also, Pierre Poilievre, leader of the Conservative party, who lost his seat in the Ottawa riding of Carleton but also boosted Conservative popular vote share. Meanwhile, NDP leader Jagmeet Singh, who also lost his seat, has resigned following historically low results for his party, which lost official party status in the House. Bloc Québécois leader Yves-François Blanchet kept his seat in Beloeil–Chambly, but lost about a third of its seats. Elizabeth May’s Green Party held on to her seat but she also lost her co-leader Jonathan Pedneault. Also on our radar: Heather McPherson, the NDP’s re-elected MP for Edmonton Strathcona, who some observers are saying could be the NDP’s next leader. What Conservatives are thinking now about their leader Pierre Poilievre and the path forward for their party. And how Liberal Leader Mark Carney will govern for all Canadians in a politically divided country facing threats from U.S. President Donald Trump. We’re still keeping an eye on: annexation and “51st state” threats, tariffs impacting Canadian jobs, especially farmers, truckers, auto workers, energy sector workers, construction workers and steel and aluminum workers; raising the cost of living, inflation, and unemployment in Canada; straining cross-border relationships, including the historic friendship between Windsor and Detroit. We also discuss “Team Canada,” interprovincial trade, and the rise of “elbows up” Canadian patriotism; Canadian sovereignty and backlash to ‘51st state’ threats; on the world stage, including our relationship with China, Ukraine, India; security and our status in the Five Eyes spy network, NATO and NORAD, and shifting global alliances in general. Other recent topics include: Filipino community reeling after Lapu Lapu street festival killings; “Grey divorce” and the rise of separation in late life; Canadians’ top vacation spots; migrants affected by Trump’s deportation push; the death of Pope Francis; landmark antitrust trials against Meta and Google; the sexual assault trial of five ex-world junior hockey players; the liquidation of Hudson’s Bay; the surge in measles cases, hair loss drug finasteride, extremist network 764, protests against Elon Musk and Tesla; Starlink and the rural internet; the turmoil around Israel and Gaza’s ceasefire; more adults with ADHD, Blue Ghost on the moon, genetically modified pig organs; aging well, wellness, dementia and long term care, as well as cancer and “commonsense oncology,” Greenland and Arctic sovereignty, cuts to USAID; Canada’s critical minerals; inflation; mortgages; opioids and Fentanyl, parenting, Canada’s best vacation spots, teens ditching social media; crypto power brokers in the White House; NASA’s new telescope and the making of a 3D map of the universe. The Current is produced in Toronto, Ontario, Canada — and has recently recorded live shows about the Canadian election in Surrey and Burnaby BC. And shows to come in Oshawa and the 905, Red Deer, Alberta, Quebec City and Halifax.
