The UN just released a landmark climate-change report. Here’s the grim timeline it gives us

November 18, 2022

By 2030, scientists warn, countries such as Canada must slash carbon emissions by almost half to prevent that fifth-grader from living out her old age in a world with increased floods, fires, crop failures, forced migration and infectious disease outbreaks, and to zero by 2050.

That was the conclusion of the Intergovernmental Panel on Climate Change Synthesis Report.

Climate change may have once felt like something you had to squint deep into the future to see. Monday’s report shows that the choices we make now will profoundly alter the planet today’s children live in.

“Let’s hope we make the right choices, because the ones we make now and in the next few years will reverberate around the world for hundreds, even thousands of years,” Hoesung Lee, chairperson of the Intergovernmental Panel on Climate Change, said Monday.

Alongside new, near-term targets, the report also reaffirmed the goal of net zero emissions by 2050, a goal enshrined in the Paris Agreement. But on Monday, UN Secretary General António Guterres suggested wealthy countries such as Canada need to reach net zero even sooner — by 2040.

“This can be done,” Guterres said. “Some have already set a target as early as 2035.

“In short, our world needs climate action on all fronts — everything, everywhere, all at once,” Guterres said at a news conference for the report’s release.

Federal Environment and Climate Change Minister Steven Guilbeault affirmed the conclusions of the IPCC report Monday afternoon, but did not say Canada would move to a net-zero 2040 target.

“This is a new request from the Intergovernmental Panel on Climate Change, obviously one that we will study very carefully in Canada,” Guilbeault said. “It’s one thing to simply say, well, you know, we want to reach this goal, but we have to give ourselves the means to get there. We do that now in Canada for 2050.”

While Guterres referenced a science fiction movie in his remarks, the solutions to this crisis are both well understood, already in use and, in some cases, almost embarrassingly simple. Protecting intact forests, wetlands and other natural ecosystems would have massive payoffs. Solar and wind power are already contributing energy to power grids, even in fossil-fuel-friendly places such as Texas. Bike-riding made the list.

The report is the world’s most comprehensive assessment of the current state of climate change. The last synthesis report came out in 2014, and acted as both a major impetus and the scientific underpinning for the historic Paris Agreement, when nearly all the world’s governments agreed to reach net-zero greenhouse gas emissions by 2050. That goal is necessary to keep the world within 1.5 degrees of warming, a critical guardrail that, if overshot, will lead to increasingly destructive planetary outcomes, some irreversible.

The synthesis report released Monday concludes years of work by hundreds of scientists around the globe, and will set the stage for a different kind of momentous meeting later this year: a conference at which nations will assess their Paris commitment progress so far.

The actions pledged by nations so far are insufficient to keep the world within that guardrail, and would result in 2.8 degrees of warming by the end of the century, the UN’s initial assessment found. The world will gather again in Dubai starting in November to conclude that global “stocktake.” (The Toronto Star)

From fire to ‘atmospheric river’: Why B.C. is trapped in a world of climate extremes

The past few months will not soon be forgotten in Merritt, B.C.

August 13, 2021

During a record-smashing heat wave that devastated British Columbia this past summer, its population of more than 5,000 people endured temperatures reaching 44.5 C. Soon after, it was racked by drought conditions and was the subject of an evacuation alert because of nearby forest fires. And on Monday, an evacuation order for the entire B.C. Interior city was issued in the face of epic flooding.

These climate-change-fuelled extreme weather events are connected: With intense heat comes wildfires, and with wildfires come changes to the soil and vegetation that can exacerbate the effects of heavy rainfall.

Similar scenes played out across B.C. Other communities that have suffered extreme flooding and landslides include Princeton, Abbotsford and Hope.

Bridges were washed out, and numerous highways were cut off in both directions by multiple mudslides and flooding. Some stranded motorists were evacuated by helicopter. At least one person has died.

It’s all because of heavy rainfall from a phenomenon known as an “atmospheric river.” They occur commonly throughout western North America, but this one has dumped atypical amounts of precipitation throughout the region.

According to preliminary Environment and Climate Change Canada data, 20 communities across B.C. experienced record rainfall for a Nov. 14, including Abbotsford, Langley, Nanaimo, Vancouver and Victoria. Though the final tallies aren’t in, for some communities those are historic records.

November 10, 2021

“Abbotsford and Hope had their wettest days in their record-keeping,” said Armel Castellan, a warning preparedness meteorologist with Environment Canada. “It’s certainly above a 50-year return period, and actually over 100 in many locations.” (A 1-in-100-year event has a 1-per-cent probability of occurring in any given year – that is, exceedingly rare.)

Recent research has shown a rising trend in atmospheric rivers making landfall on North America’s West Coast in recent decades. As the world continues to warm, they’re expected to become even more frequent and more intense.

“It’s so important to point out the role that climate change plays in these kinds of events,” said University of British Columbia climate scientist Simon Donner.

An atmospheric river is an intense and narrow band of moisture-laden air commonly associated with mid-pressure cyclones that bring heat and moisture from the tropics to the poles. They’re a bit like high-altitude air currents, such as the jet stream, except they’re concentrated in the first several hundred metres above the Earth’s surface.

They’re long (more than 2,000 kilometres), narrow (up to a few hundred kilometres wide) and can be up to a few kilometres deep. According to a Journal of Hydrometeorology study cited by the National Aeronautics and Space Administration, the passage of an atmospheric river over a coastal site takes on average 20 hours.

Climate change report a ‘code red’ for humanity

This week’s report from the United Nations climate panel makes for arresting, frightening and depressing reading. 

September 16, 2020

It comes in a summer of record-breaking heat waves that scorched Canada and Europe. It comes after deadly floods ravaged China, Germany and Belgium and as drought threatens 400,000 people in Madagascar with starvation. And it falls with an ominous thud on the world’s doorstep after wildfires incinerated large swaths of the planet, around the Mediterranean Sea, throughout Siberia and right here in North America.

Lest any climate-change deniers still delude themselves into thinking such extreme weather has no connection to what humans are doing, the report from the UN International Panel on Climate Change — it’s the sixth such assessment since 1988 and took eight years to prepare — sets the record straight. What they’ve written isn’t science fiction; it’s science fact that draws on the work of 234 experts.

Human activity is “unequivocally” changing the Earth’s climate in ways “unprecedented” in thousands, even hundreds of thousands of years and is directly linked to these and other extreme weather events. Period. Many of these changes, including higher sea levels, are now “irreversible” the climate scientists said.

September 24, 2019

As a result, after the decade from 2011 to 2020 proved the hottest ever recorded, temperatures are likely to rise in the next 20 years by more than 1.5 C above pre-industrial levels. If that happens, not only will it blow away the climate-change goals set by the 2015 Paris Agreement, it will usher in even more extreme weather and devastation.

Yes, this makes for a depressing read. But rather than make people despair and feel like giving up, the message of this report also includes hope. There’s the hope of humans working together as never before to limit the damage they’re inflicting on the planet. There’s the hope that, while not escaping unscathed, humankind will be able to avoid the absolute worst-case scenarios for climate change. And, aside from the report itself, there are hopeful signs more and more people are finally ready to do what is necessary. 

American President Joe Biden is far more committed than his predecessor, Donald Trump, ever was in marshalling the energies of the world’s biggest economy and second-largest source of greenhouse gas emissions against global warming. That alone could be a game-changer. In October, the United Kingdom will host the governments of 197 countries at the 26th UN Climate Change Conference in Glasgow. This week’s IPCC report should spur them to come together by acting together for everyone’s sake.

And if Canadians, as expected, go to the polls in a general election this fall, they have a timely opportunity to elect a government that will redouble the nation’s efforts to keep the planet from overheating. As a rich country, we have a moral responsibility to do this, and accept our role in shepherding the world to a sustainable future, even as we realize we will have to alter our lifestyles and an economy heavily reliant on the petroleum industry.

In the words of UN secretary general Antonio Guterres, this week’s landmark IPCC study amounts to a “code red for humanity.” Now it’s up to Canadians and the rest of humankind to decide if they’ll answer or ignore the alarm. To be sure, we’ll have to live with many of the terrible, wrenching changes we have wrought. But if humanity grabs the nettle in front of it, it could mitigate the impact of climate change and even avoid a world where entire regions become uninhabitable for us. 

We have a decade or so to do this, the UN scientists warn. There probably won’t be another report from the International Panel on Climate Change before the time for effective change runs out. (Hamilton Spectator Editorial)

Doug Ford links Ontario floods to climate change: ‘Just rips your heart out’

Ontario Premier Doug Ford says he believes climate change is among the reasons eastern Ontario homeowners are trying to save their homes from flooding for the second time in three years.

February 28, 2019

Ford was in the rural west end of Ottawa Friday morning, touring flooded areas along the Ottawa River, where officials are warning a new rain storm will make water levels rise rapidly over the next few days, likely exceeding the levels seen during a 2017 flood.

Ford says when you see the affected people face-to-face it “just rips your heart out.”

“These folks can’t go through this every single year,” he said.

He said local officials desperately need volunteers to help fill and distribute sandbags.

The Ottawa River is just one of several water bodies overflowing this week, forcing thousands of Canadians from their homes in Ontario, Quebec and New Brunswick, where the Saint John River is experiencing a major flood for the second year in a row.

December 1, 2018

In Quebec, officials said Thursday 3,148 homes are already underwater and another 2,305 are surrounded by it, with 1,111 people out of their residences. In New Brunswick, 84 roads are closed because of flooding, including a portion of the TransCanada Highway.

Ottawa Mayor Jim Watson declared a state of emergency because of flooding Thursday, with another 20 mm to 50 mm of rain forecast to fall Friday and Saturday.

Residents in several small communities on the eastern and western edges of Ottawa are sandbagging to keep their homes dry, while paths along the Ottawa River in downtown Ottawa, including behind Parliament Hill, are underwater. About 400 soldiers have been deployed to the Ottawa area to help sandbag and assist with other flood operations. (Source: Hamilton Spectator)
