How AI is tackling food security, disaster response and other global challenges
AI for Good is more than a buzzword—it's a powerful tool tackling global challenges like food security, disaster response, and water conservation. Microsoft’s Brad Smith highlights real-world examples, such as using AI to analyze water data in Kenya, offering actionable solutions for governments and communities. Through collaborations with universities and NGOs, AI is driving progress on the UN's Sustainable Development Goals, turning technology into a force for societal improvement.
Smith spoke during GZERO’s Global Stage livestream, “Live from the United Nations: Securing our Digital Future,” an event produced in partnership between the Complex Risk Analytics Fund, or CRAF’d, and GZERO Media’s Global Stage series, sponsored by Microsoft.
A smoky Toronto skyline is seen from the CN Tower as wildfires in Ontario and Quebec continue to burn.
Smoky skies part of new normal as planet heats up
Residents of Canada’s capital awoke to hazy yellow skies on Monday. The Air Quality Health Index showed that the pollution level was putting residents at high risk. The day tasted like a campfire.
Ottawa was under a pall because of wildfires, both small ones nearby and big ones farther away in northern Quebec. A cold front spread the yellow blanket across the Great Lakes. Toronto, Montreal, Chicago, Indianapolis, Cincinnati, and much of Wisconsin were hazy on Monday. By Tuesday, the smoke had crept in over Boston, New York, and Washington. By the end of the week, it would be noticeable as far south as Nashville. Half of Canadians and a third of Americans can expect to experience unhealthy air quality by week’s end.
Last week, the emergency was in Nova Scotia, where 18,000 people had to be evacuated from their homes after fires broke out in suburbs outside Halifax, where Hurricane Fiona downed many trees last year, leaving the woods full of dry kindling. Nova Scotia got some rain over the weekend, and the threat has receded, but it has been dry in Quebec, where 153 fires are burning, and 14,000 people have been evacuated from remote communities.
The provincial fire service is in triage mode, only fighting fires that threaten communities. Help would usually be expected from the rest of Canada, but many of those provinces are also on fire, so Quebec has had to look to the Canadian Forces for help. Firefighters from France and the United States are flying in to help, and the province is looking for help from Costa Rica, Portugal, and Chile.
On the West Coast, in British Columbia, the situation is almost just as grim. It’s early in the season, but the woods are dry and warm, and one fire there is already one of the largest ever recorded.
The new normal
Across Canada, 413 fires are burning, and 26,206 people are under evacuation orders. An area larger than Belgium has burned already this year — about 13 times the 10-year average — and the season is just getting started.
Officials warned Monday that Canadians can expect to smell smoke into August. The woods are too dry and too hot, the result of the accumulation of greenhouse gases in the atmosphere, which has dried up the boreal forests that ring the top of the planet. Seasonal fires are part of the ecosystem in the boreal ring, but the fires are getting bigger, hotter, and more dangerous as the climate changes. The forest floor is so dry and warm that the wildfires behave in new ways, spreading at night, for example, where in the past they would die down after sunset. Fire season starts earlier and lasts longer.
Some of the worst fires produce pyrocumulonimbus clouds, what NASA calls “fire-breathing dragons” — towering cauliflower-shaped systems that produce their own weather like high winds and lightning strikes, which spawn even more fires. They suck smoke and moisture up into the stratosphere, where it is carried around the world.
All of that combustion is sending vast amounts of carbon into the atmosphere, accelerating global warming. Europe’s Copernicus Atmosphere Monitoring Service measured 54.8 million tons of emissions from Canadian fires in May, more than double the amount in any May since 2003, when it began tracking emissions.
Forests producing CO2
In his recent book “Fire Weather,” Canadian journalist John Vaillant points out that since the turn of the century the world’s wooded carbon sinks — including the Amazon rainforest and the boreal ring — have become net carbon emitters.
“In other words, what used to be a reliable source of carbon storage is now generating more CO2 than it is sequestering,” Vaillant writes. “This grave reversal is one of the most pernicious developments of the Petrocene Age. As forests heat up and die — from disease, beetle infestation, fire, logging, land clearing, and drought, they skew the CO2 balance even further. It is not that living, growing trees don’t continue to absorb carbon, it is that they are no longer keeping pace with the emissions of their sick, dead, and burning neighbors.”
There is a horrifying risk of an enormous release of emissions if the tundra above the treeline catches fire, Vaillant adds.
“We are, right now, witnessing the early stages of a self-perpetuating and self-amplifying feedback loop, accompanied by myriad ‘cascade effects.’”
Planning for disaster
This is an urgent matter for leaders, not just because there are processes underway that could render much of the planet uninhabitable, but also because we have no choice but to change how we live in this hot new world.
The centerpiece of Vailliant’s book was the 2016 fire — nicknamed “the Beast” — that destroyed much of the northern Alberta town of Fort McMurray, which cost the economy about CAN $9 billion, including CAN $3.58 billion in a direct hit to insurers. Insurance companies are turning away from the risk in California (and from the risk of hurricanes in Florida and Louisiana).
The climate is making fires more common, but our building practices are making them more costly. Many homes are built in the “Wildland-Urban Interface” — among the trees, which makes them vulnerable when the trees go up. Half of Canadian homes and a third of American homes are in the WUI. Planners need to change that.
During the fires last month in Halifax, the city had to quickly build gravel roads to provide new emergency exits to subdivisions where residents could be trapped, something it ought to have done years ago.
And we need to plan for more effective firefighting. On Monday night, Canadian parliamentarians held an emergency debate to discuss creating a new national firefighting service to back up provincial governments in years like this.
Ultimately, of course, what we need to do is stop putting so many emissions into the atmosphere. There are reasons to be hopeful about that, given the shift to electric vehicles and away from coal. Both Justin Trudeau and Joe Biden have pushed hard for policies to bring down emissions. Trudeau has introduced a carbon tax against fierce opposition and is risking his government by pushing for an emissions cap in the oil patch. Biden has built his presidency around an industrial strategy to hugely expand green energy.
“They are both pushing as hard as their domestic politics will let them,” says Eurasia Group Vice Chairman Gerald Butts. But those policies will not have an immediate impact. “It’s not an individual cigarette that gives you lung cancer. It’s 40 years of smoking.”
In 2016, the year the Beast devoured Fort McMurray, scientists noted with alarm that the concentration of carbon in the atmosphere reached 403.3 parts per million, up from 400 in 2015. On Monday, the National Oceanic and Atmospheric Administration reported that we are now at 424.
As long as that number keeps going up, so will the number of fires.

The history of disasters
It's easy to judge the Pompeiians for building a city on the foothills of a volcano, but are we really any smarter today? If you live along the San Andreas fault in San Francisco or Los Angeles, geologists are pretty confident you're going to experience a magnitude 8 (or larger) earthquake in the next 25 years—that's about the same size as the 1906 San Francisco quake that killed an estimated 3,000 people and destroyed nearly 30,000 buildings. Or if you're one of the 9.6 million residents of Jakarta, Indonesia, you might have noticed that parts of the ground are sinking by as much as ten inches a year, with about 40 percent of the city now below sea level.
The fact is, human beings just aren't all that great at learning from past disasters, and that includes the ones we can see coming, like those caused by climate change. Firefighters in the American West, for instance, are bracing for the worst wildfire season in recorded history, thanks to protracted drought and record-high temperatures. And yet, a June report found that California state and local officials are encouraging rebuilding in areas destroyed by wildfires.
After more than a year of enduring the greatest calamity of our lifetimes in the COVID-19 pandemic, it's time we learned a lesson or two from the disasters of the past.

Climate change isn’t the most immediate threat to humanity, argues Niall Ferguson
Was the world so focused on climate change that warning signs about the COVID-19 pandemic were missed? Historian and author Niall Ferguson argues that, while the climate crisis poses a long-term threat to humanity, other potential catastrophes are much more dangerous in the near future. "We took our eye off that ball," Ferguson says about COVID, "despite numerous warnings, because global climate change has become the issue that Greta Thunberg said, would bring the end of the world. But the point I'm making in DOOM [his new book] is that we can end the world and a lot of other ways, much faster." Ferguson spoke with Ian Bremmer in an interview for GZERO World.

The 2020 pandemic was hardly “unprecedented,” says historian Niall Ferguson
"We've been dealing with pandemics from the earliest recorded history. Thucydides writes about a pandemic in the history of the Peloponnesian War. So the last thing 2020 was, was unprecedented," Stanford historian Niall Ferguson told Ian Bremmer on GZERO World. Ferguson, whose new book, "Doom: The Politics of Catastrophe," believes that the world should have been better prepared for the COVID-19 pandemic based on the numerous health crises of the 20th century, from the 1918 Spanish flu to influenza and HIV/AIDS. He provides perspective on how the COVID crisis stacks up compared to other pandemics throughout history.

The surprising history of disaster
COVID-19 was a global catastrophe that blindsided the world's wealthiest nations, and it's far from over. But as disasters go, it was hardly unprecedented. Humanity has a long history of failing to prepare for the worst, from volcanic eruptions to earthquakes to famines to shipwrecks to airplane crashes to financial depressions. But how do we get better at preventing such calamities from happening, and how many seemingly unavoidable "natural" disasters are actually caused by humans? On GZERO World, Ian Bremmer talks about all that and more with Stanford historian Niall Ferguson, who is just out with the perfect book for the topic, "Doom: The Politics of Catastrophe." Plus, a look at how one young Ugandan activist was literally cropped out of the global climate fight.
Podcast: How human history is shaped by disaster, according to Niall Ferguson
Listen: Stanford historian Niall Ferguson joins Ian Bremmer on the GZERO World podcast to talk about the geopolitics of disaster. Throughout human history we seem to be unable to adequately prepare for catastrophes (natural or human-caused) before they strike. Why is that? And as we emerge from the greatest calamity of our lifetimes in the COVID-19 pandemic and look to the plethora of crises that climate change has and will cause, what can we do to lessen the blow?

Niall Ferguson: Blame bureaucrats, not leaders, for mismanaging disasters
When a government fails on disaster response, Stanford University historian Niall Ferguson says we often point the finger at the wrong person: the president — even if he's Donald Trump — instead of the mid-level bureaucrats who're actually responsible for most decisions. "When people are inclined to blame the person at the top, on closer inspection the point of failure is not there," Ferguson tells Ian Bremmer in the upcoming episode of GZERO World.
