Pakistan floods show need for action on climate finance, say developing countries

In this week's issue of our environment newsletter, we look at why a group of developing countries is hoping to make climate finance a key issue at the upcoming COP27 and examine the unintended effects of tidal power.

Who pays for the cost of climate-linked catastrophe in Pakistan?

This week, we ask what role Canada needs to play in providing aid to Pakistan as it confronts an ongoing climate hazard. And, a documentary about how the world helped mend the ozone layer, and what lessons it holds for today's climate crisis.

Most climate policies worldwide do not consider the rights of people with disabilities

A professor tells us why he's speaking up for disability and climate.

Canada is developing a clean electricity standard. Does Hawaii have lessons for us?

Canada is developing a clean electricity standard reach its commitments to a net-zero grid by 2035, but its not the first jurisdiction to do so. Hawai'i's own standard helped fast-track the state's transition to renewables.

ENCORE: Why addressing energy poverty is a climate solution

We hear why equity and climate action need each other. Producer Rachel Sanders talks to farmers facing mental health impacts of environmental extremes. And, quitting for the climate? A wildlife ecologist tells her story.

Heat waves are here to stay, but Vancouver community groups are finding new ways to keep people safe

In this week's issue of our environment newsletter, we look at how communities in Vancouver are battling heat waves and examine the disturbing items various droughts have exposed this summer.

The polar bear became an 'accidental icon' of climate change. Is it time to rethink that?

When biologist Andrew Derocher discovered in the 1990s how polar bears were affected by climate change, his work helped launch the charismatic critter as an icon — used by activists as a poster animal for a warming world, and exploited by climate deniers to argue the opposite. But get close and the story of Arctic change is more complex.

ENCORE: For the love of swamps and for the sake of cities

Mired. Bogged down. Swamped. You might not hold wetlands in high esteem, but many say they're worth protecting in the name of climate change. And, we hear the case for giving cities more money and power as they find themselves on the frontlines of global warming.

US climate bill brings widespread relief and a few questions

After a rollercoaster of negotiations, the US senate passes a landmark climate bill. Can it cut enough CO2? We hear how a Vancouver community group is keeping people cool. And, a feature documentary about how polar bears became a climate icon, for better or worse.

Lessons Learned from COP26

As we countdown to COP27 in Egypt, we look back at last year's conference, where it fell short and why trust is an important part of climate negotiations.

ENCORE: Literature for life in a changing climate

Looking for some summer reads to beat the heat? Climate literature is here to help. Kids' books support parents with the “climate talk” and adult fiction explores fear, hope and community resilience.

Why reporting on GHGs more often would help Canada advance its climate agenda

Canada should follow Europe's lead and report statistics on greenhouse gas emissions quarterly instead of annually — a move that would also bring them in line with the way economic indicators are reported, says a prominent environmental economist.

Drought, deluge and the fix: do what water wants

Science journalist Erica Gies shares solutions to living with water extremes. How statistics can shape climate solutions. A physician in Yellowknife weighs in on wildfire smoke and health. And, a paramedic shares news about the rollout of electric ambulances in British Columbia.

As the Atlantic Ocean warms, fisheries scramble to adapt

One impact of greenhouse gas emissions is the warming ocean, with hot spots in the North Atlantic. As fish species respond by moving farther north, expanding and shrinking their ranges, the rules about what can be fished, where and how much are lagging behind the speed of change.

How protecting caribou can help climate

Across Canada, climate change is exacerbating challenges caribou herds already face. But research shows protecting caribou habitat could have other benefits for climate. And, an analysis from Harvard measures how ExxonMobil used language to make individuals feel responsible for climate change, similar to the strategy used by tobacco companies in the past.

Climate hope remains despite U.S. Supreme Court ruling

Why retired scientists may have already discovered today's green energy solutions

What on Earth's Molly Segal takes a look back at how the oil crisis of the 1970s sparked concerns about energy costs and security, prompting research that's taken on new meaning today in a warming world.

A vote for justice
