We learned about climate change in the 1980s in school, and I distinctly remember that a whole bunch of new cars around 1986 and 1987 came painted green. I had never seen green cars before during my lifetime as a school aged kid. To me it was a new color for a car. In my childhood brain it was an obvious connection to the perception that gas cars were considered problematic. [ * ]

If I remember correctly the mass media around 1988 was saying that we could only grow carbon for a few more years and then we would have to plateau carbon production on a per annum basis.

[ * ] at around the same time as this was going on, there was a famine in Ethiopia, and I learned that automobiles in north America had been implicated in causing the drought in Africa because they modulated ocean evaporation rates. And that globally cars don't really cause most of the CO2. The system started to seem very complicated and the dynamics were not simple cause-effect chains...

The only way out of this is significant carbon capture on top of emitting more and we have no technology to do this effectively at all.

Two responses.

Response #1 is that this is the same logic that the IPCC and many other climate agencies keep bringing up. In my humble opinion they are basically just giving us this idea that mathematically we can still fix this via carbon subtraction but they don't really touch on the viability of this as a practical alternative. The problematic part is that if the technology doesn't exist and can't even theoretically exist because of basic thermodynamics, this is actually not a scientifically / technically sound idea even if the math was numerically valid in some divorced from reality sense.

Response #2 is that the argument is actually fundamentally wrong on one basic element. In order to reverse warming, we would have to now do climate forcing in the cooling direction. What is required is for the earth energy balance to go back in the opposite direction which would require we artificially lower CO2 below the pre industrial starting point and leave it there for decades and decades to actually refreeze the cryosphere and reverse everything. Most of the "net zero/ carbon capture" schemes are only considering a "pause" of additional pollution, not any sort of repair of the earth climate system. Its important to notice they want to do carbon sequestration to limit the warming to 1.5 or 2.0, not to sequester the CO2 to MINUS 1 to eventually put us to 0.0. Zero is the eventual "fix". 1.5 isn't a "fix". So like...

The conclusion is that this is 96.3% psychological and not really a serious idea. This is telling people what they want to hear and nobody wants to be the person yelling fire in a crowded theater and starting an existential crisis...

You can tell this is purely a mirage because some very basic arguments simply demolish the illusion. This is grade school level math and science just being applied critically and the whole idea falls completely apart in a fairly horrifying way. It's clearly a farce.

The decision of humanity has been made. And it has become rude to point it out.

Based on the findings, all temperature records are already close to 2.7 degrees F (1.5 degrees C) of warming above pre-industrial levels and are on track to exceed that level before 2030. To be clear, Earth’s global temperature would need to exceed this limit for an average of 20 years to officially breach the Paris Agreement, and that’s where we’re currently heading, according to the researchers.

This technicality tells you everything. Its not that we want the best truth from the data we observe, we want to postpone the truth at least one human generation / political cycle / career.

The report’s authors cited earlier work that found limiting heating to about 1.8C required global emissions to be halved by 2035. They said existing national policies were projected to lead to at least 2.3C heating, but it would still be possible to limit stay below 2C if countries delivered on net zero emissions commitments by mid-century.

Climate Analytics, a science and policy institute, applauded the report for clearly describing the problem, but said it did a poor job of “showing us that there is a way out”.

That checks out. I could tell the trail gets some use so I assumed I had bad timing. Gotta return. I was a visitor, but incredible area on the Kenai...

Cool, those are some riding zones I'll have to add to my bucket list.

It seems like the bucket keeps filling up. Lol.

Similar story from the Waldo Lake trail this year. It started the season with 400 logs across and the forest service went and knocked it down to 100 but it seems as if they quit at that point. On Trailforks a guy from the COTA saw crew wrote that he offered to volunteer on the opening and he was told he's not welcome to work and that the trail has now been closed. I feel that the volunteering isn't managed very well sometimes and I also don't see how the FS can keep the trails open without lots of capability from the volunteers. How can they afford to turn away trained volunteers?

I've been lucky enough to travel extensively in north America and rode bikes in a lot of places. I love it all. I have a really hard time picking a "top trail".

Anyhow, trails that are on my top ten list tend to be big memorable epic all day shuttle drop rides. I really enjoyed Frisby Ridge in Revelstoke and The Lemmon Drop and CDO in Tucson. My all time favorite destinations are probably Kingdom Trails, Sedona, Whistler, Fruita and St. George.

My riding style is kind of rare because I am not a great rider in any one discipline but I color outside all the lines. I can ride DH and Enduro and hang with faster riders, but i can also do all day pedal fest rides and enjoy backpacking and pure fitness riding also. So with a ride like the Lemmon Drop, it has a lot of "flow state" where I'm doing a huge all day endurance ride but there is also a lot of bigger tech and scary drops and rock rolls mingled into the experience. I have a whole list of secret trails that I can't share from BC, PNW and the Rockies that are at a higher level DH hidden away in the backcountry. That's basically my jam.

Does Resurrection Pass ever become less buggy in August and September? Amazing area but I think I hit the trail at peak mosquito season (June?) and it was so heavy for bugs that its almost hard to describe. Like a constant swarm of clouds of mosquitoes. Probably the #2 worst place I've ever been for mosquito levels.
