What on Earthwith Laura Lynch

A public inquiry in Alberta into alleged foreign-funded anti-energy campaigns commissioned a pair of studies critics call “textbook climate denial.” We look at why this persists in Canada, and how to go beyond debunked arguments against climate science.

Reducing the carbon footprint of homes across Canada is no easy task. What role does home heating play? Individual homeowners and community-lead initiatives are taking action to make a difference.

With the stroke of a pen Joe Biden cancelled the Keystone XL pipeline, and now calls are growing for a 'just transition' — a shift from fossil fuels to a low carbon economy that doesn’t leave workers behind. We look at the barriers and how it could work.

Unlike monsters under the bed, the climate threat is real — and so is kids' and teens' anxiety about it. So how to talk climate? A top anxiety expert weighs in.

Activist Severn Cullis-Suzuki, scientist Katharine Hayhoe and author Seth Klein, along with other climate experts and advocates, recommend the books they think offer hope for the planet.

From lessons learned during the pandemic to his hope to hit net-zero emissions, plus some news he didn't expect to break – Jonathan Wilkinson joins us for a feature interview.

The Canadian Arctic is warming at three times the global rate. What will this mean for ice, snow and the activities supported by cold winters?

Researchers, industry and advocates are talking up seaweed and kelp as a solution to food insecurity, to methane emissions, and more. But it's also on the radar because some kelp beds are under threat from climate change.

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 has expressed interest in a new, smaller type of nuclear reactor that proponents say will be critical to help the country reach its target of net-zero carbon emissions by 2050. But there's a debate whether these new reactors are necessary to reach net-zero — or whether it's better accomplished by focusing their efforts elsewhere.

Electric vehicles are growing in popularity in Canada, with sales doubling in 2018, but EVs still only make up about three per cent of new vehicle sales. That means there's a long way to go to hit the ambitious federal targets of 100 per cent of new light-duty vehicles are zero emissions by 2040.

How to keep warm on a patio without heating the planet, solar power reaches a new milestone, and this week's episode: hope vs. fear in the language of climate change.

Our choices about the foods we eat make “a huge difference” on the environment, and governments should enact strong food-related policies to help the fight against climate change, according to food researcher Marco Springmann.

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. This week, What on Earth looks at a bold proposal to save ice with technology — and plans to protect what’s left.

Smoke in the summer has become common in B.C., a province with a warming climate marked by longer, nastier wildfire seasons. As the environmental catastrophes become more regular, so too do the psychological consequences — a sensation called "ecological grief" or "ecological anxiety," caused by seeing loss in the natural world.

A new study shows glacial lakes have increased by 50 per cent since the 1990s due to climate change and glacier retreat. As the effects of glacier melt are being felt by communities downstream, glaciologist Shawn Marshall says we need more decisive action on climate change.
