Wildfire smoke is like smoking 'half a pack a day.' Here's how to protect yourself As Canadian wildfires spread smoke across the U.S. the air pollution is dangerous to health. But there are ways to protect yourself. Here's what to know.

β€œOn Monday the AQI in Detroit was at least 159. On a smoky day, when AQI levels reach 100 to 200, "the exposure to the fine particulate matter, the air pollution, is similar to smoking a quarter to half a pack a day," Wilgus says.”

After a week of smoke, a look at Canada's approach to fighting wildfires differently Minnesota saw a record-breaking six-day air quality alert due to wildfires burning in Canada sending smoke into the skies. Canada is seeing one of it’s worst wildfire seasons on record.

Great discussion here on the causes of increased smoke in our Minnesota skies.
Wildfires have increased 4X in Canada and the US since the 1970s. πŸ”₯
What changed?
The climate.

We'll have some less smoky summers, but get used to smokier MN summer trend until we reduce GHG emissions.
Canada has 1.2 BILLION ACRES of boreal forests.
Hotter drier climate sucks more moisture from dry fuels.
Unfortunately this is the tip of the iceberg for smoke potential.

The economy is on the precipice of recession. That’s the clear takeaway from last week’s economic data dump. Consumer spending has flatlined, construction and manufacturing are contracting, and employment is set to fall. And with inflation on the rise, it is tough for the Fed to come to the rescue.

Unemployment remains low, but that’s only because labor force growth has gone sideways. The foreign-born workforce is shrinking, and labor force participation is declining. Telling is the economy-wide hiring freeze, particularly for recent graduates, and the decline in hours worked. 

It’s no mystery why the economy is struggling; blame increasing U.S. tariffs and highly restrictive immigration policy. The tariffs are cutting increasingly deeply into the profits of American companies and the purchasing power of American households. Fewer immigrant workers means a smaller economy.

Any notion that the economic data misrepresents the reality of how the economy is performing is way off base. There are revisions to the data, even big revisions, but they universally say the economy is doing worse. That’s because it is. 

BTW, the DOGE cuts are a key factor in the revisionsβ€”not because BLS has cut staff, although that can’t help, but because the government often reports payrolls to BLS late. It didn’t matter when government employment was stable, but now that it’s declining, the cuts are picked up in the revisions.

Trump is panicking because the economic numbers are giving a recession vibe.

This is the first time I've read an extreme scenario that seems plausible and urgent within two centuries. Other pathways to such warming require exhausting all known fossil fuels, but this cascade failure narrative seems more alarming to me.

Curious what #climatechange experts think. Thoughts?

"If this methane is released, by the middle of the next century the temperature will have already increased between 8 and 10 degrees. At this level of warming, much of the earth’s surface is uninhabitable for humans and you have the sixth largest biodiversity extinction on the planet."

A quote here from Carlos Nobre caught my attention:

"And if that happens – if the Arctic Ocean warms up by 3-4C – the amount of methane that would be released could see [air] temperatures reach 8-10C..."

Did you know that since 1750, land-use change is responsible for about *one-third* of total CO2 emissions released to the atmosphere?

About 255 billion tons of carbon, or nearly *a trillion tons of CO2e*, have been emitted.

That's basically the ghosts of *2 billion hectares of forests* in the sky.

There are some really informative perspectives in here. I’ve never liked the phrase β€œtipping point.” I think what we’re really talking about are cascade failures.

There is never a runaway level of warming, but there are cascade failures (feedbacks) that have critical thresholds.
