Guilt and generational wisdom drive seniors to take climate action

"Bittersweet." Mikyung Kim said, smiling, as she joined a large crowd holding signs. It warmed the 57-year-old's heart to see this group of Canadian seniors marching for climate action in Toronto earlier this week. 

But when she talked about why everyone was here, she started crying.

Kim described a guilt at seeing younger generations go out and protest about climate change — which she sees as ultimately her generation's responsibility. 

"It's so sad because we destroyed this world and then they are struggling." 

Kim, part of a Korean Canadian community group for climate justice, wasn't alone in lamenting the state of the world being left for future generations. Across the country on Tuesday, through marches, dances, protests and speeches, the message was clear: action on climate is needed now. And seniors, despite a higher vulnerability to climate health impacts, say they have the experience and wisdom to speak out. 

David Suzuki was one of them.

"Seniors tend to be marginalized," Suzuki said. "But … they've got something society needs. They've lived an entire life."

The 88-year-old, who recently retired from his tenure as host of CBC's The Nature of Things, was one of the keynote speakers at the Toronto event

Beyond his call to action for seniors to "get off the couch or the golf course and start telling the truth," Suzuki points to Indigenous cultures as a lesson in reverence. 

"You go to a potlatch or a funeral or a marriage, guess who are the real rock stars at those? It's the elders," Suzuki described, adding that this respect allows a greater connection between the past and the present.

Indeed, the current dangers of climate change for seniors are far different than the decades they grew up in. The increased frequency and intensity of extreme weather events such as fires, floods and heat waves hit older people harder, as they are "more likely to have health conditions that make them more sensitive to climate hazards," according to the U.S. Environmental Protection Agency. 

And while some dangers are apparent, such as restricted mobility after a disaster or heat-related illnesses, others may take years to be discovered. New research suggests a tropical cyclone can lead to millions of additional deaths in the years after it makes landfall, with the greatest death toll among adults 65 and older. 

Jim Davis is with Seniors for Climate Action Now, one of the groups that organized the event. He sees no greater urgency than climate change, calling it all-consuming for mankind. 

But he stresses that those who joined this crowd on a cloudy October afternoon aren't the ones these messages of protest need to reach. 

"Hopefully we can convince the neighbours — not the people that are in total denial, but people who are somewhat open-minded," Davis told CBC News. 

"And it's tiring, but it's still very needful to do."

Old issues of What on Earth? are here. The CBC News climate page is here

Check out our podcast and radio show.  In our newest episode : A stuffed dalmatian. An album of precious photos. A scorched doorknob. These are some of the personal items on display recently at Climate Week NYC. Meghan Fandrich and Diana Boston travelled to New York City from Lytton and Merritt, B.C., to share these remnants of the fire and flood that devastated their communities. They tell us why they hope the exhibit can make climate disaster tangible, and lead to change.

What On Earth drops new podcast episodes every Wednesday and Saturday. You can find them on your favourite podcast app, or on demand at CBC Listen. The radio show airs Sundays at 11 a.m., 11:30 a.m. in Newfoundland and Labrador.


Reader feedback

A couple of weeks ago, Dannielle Piper wrote about art to inspire climate action, including a photo of penguin chicks entombed in Antarctic ice. Peter Fretwell, lead scientist for the British Antarctic Survey, had told CBC's What On Earth that the "chicks likely died due to hypothermia after falling into melt pools." 

That prompted reader Todd Weisbrot to disagree, writing: "Those images are of emperor penguin chicks that most likely died on the sea ice and their bodies capture more heat from the sun, resulting in their bodies sinking into the ice. This is a common occurrence in emperor penguin colonies."

We went back to check with Fretwell, and he confirmed that Weisbrot is correct — the chicks pictured in the photo likely died on the sea ice, not in melt pools, and became entombed in ice the way Weisbrot described. However, he said high penguin chick mortality is linked to ongoing climate change. He added that Snow Hill Island colony, where the photo was taken, is the most northerly and one of the warmest emperor penguin colonies, and some penguin chicks do die in melt pools around the colony – they are just not captured in the photo shown.

The Big Picture: A tiny but dangerous kind of air pollution

Diagram showing relative sizes of different particles as blue-grey circles

While there has been much discussion in recent decades about smog and wildfire smoke, scientists are learning more about a category of air pollutants that are smaller in stature yet potentially more dangerous. They're called ultrafine particles (UFPs). 

A thousand times thinner than a strand of hair, UFPs are emitted by vehicles (including EVs) and industrial activity — and according to a recent study led by researchers at McGill University in Montreal, contribute to more than 1,000 premature deaths a year in that city and Toronto. 

A 2020 study from the University of Illinois found that "compared to fine particles … [ultrafine particles] cause more pulmonary inflammation and are retained longer in the lung." The study says UFPs have been found to cause cardiovascular disease and are linked to cancer and diabetes in adults; exposure can also lead to greater rates of babies with low birth weights.

In addition to looking at car-heavy urban settings, researchers are examining areas around airports. A study this year by Brussels-based advocacy group Transport and Environment suggested thousands of cases of high blood pressure, diabetes and dementia across Europe could be linked to UFPs emitted by planes.

Hot and bothered: Provocative ideas from around the web

U.K. becomes first G7 country to phase out coal. Here's how

As the clock approached midnight on Monday, workers were invited to gather in the canteen at the coal-fired power plant in the English village of Ratcliffe-on-Soar to watch a live stream of the control room at the moment the generating units were turned off for the last time.

Britain was the first country to build a coal-fired power station in 1882, and this week became the first member of the G7 to phase out the facilities altogether. 

"I think it is a good thing that it is going and it is a good thing the U.K. is leading the way," said Brian Hill, the chairman of the parish of Ratcliffe-on-Soar, near Nottingham in central England.

The 87-year-old watched the construction of the facility's eight 114-metre-high cooling towers in the 1960s, and now he is glad to see the sprawling site, which at one time employed several hundred workers, be decommissioned. 

"It's a dirty fuel," he told CBC. "I prefer cleaner air."

The country's relatively rapid transition away from thermal coal, which was a key driver of the economy and still generated 80 per cent of Britain's electricity in 1990, is "a real proof point that transition and change can come very fast," said Matthew Webb, associate director of the Coal to Clean program with E3G, a U.K.-based independent climate think-tank. "We really got to get into the next gear and move up a level in terms of retiring the coal."

Brian Hill, the chairman of the Ratcliffe-on-Soar parish, says his two children watched as the plant was constructed in the 1960s. Now, at 87, he will watch as it is decommissioned.

While many advanced economies, including Canada, have committed to phasing out thermal coal by 2030 and some European countries like Sweden and Austria have already accomplished that goal, there are still thousands of coal-fired power plants operating around the world. 

In 2023, a new record for global coal consumption was set. It was primarily driven by new plants coming online in China.

Scientists say that in order to limit global warming to 1.5 C, the target established in the Paris Agreement in 2015, coal-fired power plants need to be phased out everywhere by 2040. 

"Globally, we still face a massive challenge. We have some [2,000 gigawatts] of coal power running today. That's nearly 9,000 coal plants," Webb said in an interview.

But he said the U.K.'s ability to fast-track its phaseout of coal will hopefully set an example to other countries.

More than half of Britain's electricity now comes from renewable sources such as wind and solar power. The rest comes from natural gas and nuclear energy.

But at one time coal was the leader. It helped drive the U.K.'s industrialization and grow the country's economy. It generated the steam to run railways and power factories and communities.

The country's coal industry already went through a big decline under prime minister Margaret Thatcher in the 1980s, before global climate goals.

Still, the Ratcliffe-on-Soar plant once powered two million homes. It was slated to be closed in 2022, but under an agreement with the government, it stayed open for an additional two years because of a European-wide gas crisis triggered by Russia's invasion of Ukraine. 

The plant, which is owned by Uniper, a German-based company, employed about 350 people before work wound down. 

About half the workers will be involved in decommissioning the plant, which is expected to take two years. 

"The U.K.'s coal plants were relatively old compared to other countries that have younger coal plants, but analysis does show … that it is possible by 2040 for even these young coal plants to be retired in an economically efficient way," said Lucy Hummer, a researcher in the coal tracker program with Global Energy Monitor in Washington, D.C.

Hummer said while coal-powered capacity increased last year, she is "optimistic" that it could trend downwards soon. 

China's thermal coal plants are not operating at their maximum capacity and are expected to operate at an even lower capacity in the future.

"The significant permitting of new coal plants in China is actually coming to an end," Hummer added. "And there's hundreds of gigawatts of new renewables that are being installed."
