Alaska's technicolor rivers are rapidly spreading – and we now know why

$1:

Poulin and researcher Taylor Evinger analyzed samples taken across a period of time, and found that the orange rivers are becoming increasingly acidic, as a result of the cocktail of minerals flowing into them. Some samples returned a pH reading of 2.3, when the average 'healthy' river for the region should be at pH 8.

They found that the weathering of sulfide minerals was creating an acidic and corrosive environment for even more metals to be released. As such, high levels of iron, zinc, nickel, copper and cadmium have been found in the team's samples.

“We see a lot of different types of metals in these waters,” Evinger said. “One of the most dominant metals is iron. That’s what is causing the color change.”

New thought - axe the tax on home heating and farm fuel. Rebates only to those who live let's say 60km of a major center. IE if your postal code is within the 604 area code you get dick.

I haven't driven in 5 months, but I still get my $900 a year rebate. I'll spend it on bus passes and the occasional cab. Maybe a new bike.

‘Termination shock’: cut in ship pollution sparked global heating spurt


Particulate from burning fuel actually affects the planet because the tiny particles block sunlight, and can trap heat. Because 'cleaner' fuels were mandated for shipping traffic, and reduced shipping because pandemic, the reduction in pollutants caused warming the following year, making 2023 the hottest year recorded.

This is why many are against climate engineering on a planetary scale.

$1:

Deliberately pumping aerosols into the air over the oceans to stimulate more cloud cover has been proposed as a way of cooling the Earth. Yuan said years of shipping pollution followed by a sharp cut was an accidental large-scale experiment: “We did inadvertent geoengineering for 50 or 100 years over the ocean.”

The new analysis indicates that this type of geoengineering would reduce temperatures, but would also bring serious risks. These include the sharp temperature rise when the pumping of aerosols stopped – the termination shock – and also potential changes to global precipitation patterns, which could disrupt the monsoon rains that billions of people depend on.

'cleaner' is relative. The bunker fuel used in shipping is like the difference between raw sewage and a pig pen. Sure, the pig pen may be cleaner, but is it clean?

TLDR he is right and plating trees to correct for climate change will be as effective as our current recycling regime.

[DrCaleb]

The flaw with planting trees has always been; seeds to grow the trees aren't easy to come by. They already plant so many trees to farm every year, and that is stretching the production system tight. Another trillion trees is night impossible.

A problem that has been in the works for over a lifetime will not be fixed overnight by a cheap shortcut.

[DrCaleb]

It won't be fixed by expensive solutions either. It could have been fixed 30 years ago when Hansen showed us that this was coming. Solutions now can only be economically catastrophic.

Perhaps it will usher the post money, post capitalism phase of our society. And that is just, as it was capitalism that insisted on lying about the issue in order to maintain profit margins. It's true, they will sell you the rope used to hang them.

Hottest May on record spurs call for climate action

Earth broke heat records 12 months straight


It took 150 years since the industrial revolution started changing the climate, it will not be mitigated overnight. In the mean time, there will be huge costs associated with the effects.
