North America’s Devastating Wildfires, Viewed From Space
North America’s Devastating Wildfires, Viewed From Space
If you live on the west coast of North America, it’s likely that you’ve felt a bit smoked out, lately.
Wildfires in British Columbia, Canada are already the worst in the province’s history, while California has had a particularly rough season with human deaths, evacuations, and billions of dollars of damage.
Oregon has one confirmed death from a wildfire in mid-July, and Washington hasn’t gotten off easy, either. On July 31, 2018 a state of emergency was declared in the Evergreen State.
Visualizing Wildfires From Space
Today’s image comes to us from NASA, and it shows aerosols around the world including those originating from volcanoes, desert dust, cloud cover, sea-salt – and of course, smoke.
Here’s the same image with labels, indicating black carbon on the west coast of the continent:
The wildfires are just as visible as the massive slash-and-burning occurring in Central Africa, hurricanes and typhoons, and even the dust swirling up from the Sahara, the world’s largest desert.
Here’s a visualization of the fires in North America, with some extra zoom:
It’s clear from this image that smoke isn’t just affecting the coast – in fact, experts say it has been travelling as far as Ireland, in lesser concentrations of course.
Other Visuals
While we thought the visualization above was the most striking, there are countless of other examples from the last month that show the extent of wildfires and smoke on the west coast.
Here’s another shot from NASA from a few weeks ago, during peak wildfire season in California and Oregon:
And here’s an image of Seattle and Vancouver from mid-August, when smoke from Canadian fires was so bad in those cities that it was like “inhaling seven cigarettes” per day:
Future Forecast
As we roll into September, the worst of the wildfire season is over.
Unfortunately, it’s already been the worst in British Columbia’s history. Here are the 10 worst fire seasons graphed since 1950, based on square kilometers burned:
Data as of Aug 29, 2018, and from the BC Forest Service
While this year has been an anomaly, it may also be a preview of what’s to come. One recent report out of California said that the number of wildfires over 25,000 acres is likely to increase by 50% leading up to 2050.
Is this the new normal?

Charted: The Safest and Deadliest Energy Sources
What are the safest energy sources? This graphic shows both GHG emissions and accidental deaths caused by different energy sources.

Charted: The Safest and Deadliest Energy Sources
Recent conversations about climate change, emissions, and health have put a spotlight on the world’s energy sources.
As of 2021, nearly 90% of global CO₂ emissions came from fossil fuels. But energy production doesn’t just lead to carbon emissions, it can also cause accidents and air pollution that has a significant toll on human life.
This graphic by Ruben Mathisen uses data from Our World in Data to help visualize exactly how safe or deadly these energy sources are.
Fossil Fuels are the Highest Emitters
All energy sources today produce greenhouse gases either directly or indirectly. However, the top three GHG-emitting energy sources are all fossil fuels.
Energy | GHG Emissions (CO₂e/gigawatt-hour) |
---|---|
Coal | 820 tonnes |
Oil | 720 tonnes |
Natural Gas | 490 tonnes |
Biomass | 78-230 tonnes |
Hydropower | 34 tonnes |
Solar | 5 tonnes |
Wind | 4 tonnes |
Nuclear | 3 tonnes |
Coal produces 820 tonnes of CO₂ equivalent (CO₂e) per gigawatt-hour. Not far behind is oil, which produces 720 tonnes CO₂e per gigawatt-hour. Meanwhile, natural gas produces 490 tonnes of CO₂e per gigawatt-hour.
These three sources contribute to over 60% of the world’s energy production.
Deadly Effects
Generating energy at a massive scale can have other side effects, like air pollution or accidents that take human lives.
Energy Sources | Death rate (deaths/terawatt-hour) |
---|---|
Coal | 24.6 |
Oil | 18.4 |
Natural Gas | 2.8 |
Biomass | 4.6 |
Hydropower | 1.3 |
Wind | 0.04 |
Nuclear energy | 0.03 |
Solar | 0.02 |
According to Our World in Data, air pollution and accidents from mining and burning coal fuels account for around 25 deaths per terawatt-hour of electricity—roughly the amount consumed by about 150,000 EU citizens in one year. The same measurement sees oil responsible for 18 annual deaths, and natural gas causing three annual deaths.
Meanwhile, hydropower, which is the most widely used renewable energy source, causes one annual death per 150,000 people. The safest energy sources by far are wind, solar, and nuclear energy at fewer than 0.1 annual deaths per terawatt-hour.
Nuclear energy, because of the sheer volume of electricity generated and low amount of associated deaths, is one of the world’s safest energy sources, despite common perceptions.
