What on Earth?

There is huge potential in Canada to harness heat from deep below the ground for electricity. So why are there only a handful of projects breaking ground? We take a look at the promise of renewable geothermal power and the barriers to getting there.

Canada hasn’t met a climate target yet. Trudeau’s Liberals just introduced new accountability legislation — but how strong is it? We get reaction, look at lessons from the U.K.’s ‘gold standard’ climate law, and hear what we still need to reach net-zero.

President-elect Joe Biden's win means a United States that again plans to act on climate science — a huge shift from the past four years under Trump. Experts anticipate far-reaching impacts: to policy, innovation, and pressure on Canada to ‘step up.’

Canada’s resource minister says there’s no path to net-zero without more nuclear development, and the push is on to develop small modular reactors. But uncertainties remain — and experts disagree whether they’re the climate solution we need.

It's an idea that's been framed as a simple solution to a warming climate – plant more trees. On both sides of the border politicians of all stripes have promised to plant billions and trillions of trees - but how feasible is it to deliver and what impact would it really have?

Enthusiasm for electric vehicles is rising in Canada — as are sales — but there’s a huge gap between today’s reality and Ottawa’s goal for zero-emission vehicles by 2040. We’ll hear what’s holding back would-be EV drivers, and what needs to change.

Greta Thunberg told the world: ‘I don’t want you to be hopeful. I want you to panic.’ Many climate messages focus on fear — it’s powerful, but can also backfire. Hear why hope can be crucial, and the risks of making a worst-case scenario feel inevitable.

Fabrice Retiere will sit down to a meatless Thanksgiving this year for the first time. Research suggests he might not be the only Canadian doing so, as Canadians show more interest in eating less meat. This week we delve into the demand for plant based protein, the companies capitalizing on the demand, and why scientists and policy experts say more needs to be done to get people on board if we want to help our climate.

When your backyard is burning, is anywhere safe? Welcome to World on Fire, a six-part original podcast from CBC Edmonton that takes us to the front lines of out of control wildfires in Canada, Australia and California. Recorded during the COVID-19 pandemic, hosts Adrienne Lamb and wildfire expert, Mike Flannigan look at what it takes to find hope in the midst of fear and destruction.

This summer, Arctic sea ice hit a near-record low, second only to 2012 as the biggest melt on record. By 2050, many project an ice-free summer Arctic; the Earth’s white cap would be gone. We look at a bold proposal to save ice with technology — and plans to protect what’s left.
