This and glacial melt is why we need solar blocking/filtering/reflecting sooner than later, and perhaps extra focused on the poles to protect the necessary temperature differential/stop melting at our largest ice reserves. The sooner we start the less sunlight we need to block, the later we start the more sunlight we need to block. Lower or even zero emissions is not enough, the melting is much faster than predicted so our response has to be. Minimalism and population reduction doesn't actually remove the CO2 and the warming is fast enough that you don't have a good option to just wait it out over 300+ years and absorb the damage.

Stop fight our best tool for controlling heat when the heat is easily the most damaging part!

Humans have added over 2000 gigatons and things are this bad and getting worse fast. The Earth only sequesters about 4-5 gigatons per year. The rest of the CO2 stays up there and keep building up, so the Earth stays hot, ice melts, the Earth heats even faster and the zero net emissions take hundreds of years to get the climate back to normal. AND because you didn't clean the CO2 up your just shifting an atmospheric chemical imbalance into the soil and oceans.

I think just the pure emissions plan may seem like the virtuous solution vs the arrogance of solar blocking, but lower emissions without addressing the actual heat AND acidifying the oceans with all the CO2 is kind of a crap plan!

A plan that uses emissions reduction, solar blocking and artificial CO2 sequestration seems like a much safer bet and of those currently emissions reduction is somewhat practical where it works well like with fossil fuels, Co2 removal is not practical and solar blocking might be fairly easy for a massive increase in control over the heat.. but we can't know much until the public and government gets more serious about emission reduction on their own not be anywhere near enough.

There are of course the arguments about there being left-leaning echo chambers, but then you have to ask how much of that is a "both sides" argument and how much is real. Keeping in mind the "facts have a liberal bias" comments.

I don't think defending Ukraine's democracy from an obvious authoritarian invader is silly. It wouldn't be silly if it was your house being blown up for no good reason or your kids/wife getting kidnaped/raped/tortured/killed. What's the point in climate action if not to save human life? You just worried about the fish?

Climate change sucks, but if we give up all our morality just to fight climate change than why bother? You want to let all the rapist and murders free because that distract from climate action also?

If humans can't multi-task then it's just time for us to go. If we can't have reasonable law and order and basic morality AND fight climate change, just smoke em while you got em because the species isn't worth saving.

Reddit is actually better than most for getting rid of echo chambers. There’s alt right stuff on this site make no mistake but it’s not blatantly everywhere like other platforms.

That's the definition of senile, mate. What do you believe it to mean?

>Senility : the quality or state of being senile : the physical and mental decline associated with old age

>especially : the deterioration of cognitive functioning associated with old age

You may not be as brilliant as you have convinced yourself you are.

If you're looking at just the cost of driving it, yeah. But the space in cities reserved for parking has a huge societal cost.

Taxis and rideshares take up very little parking because they're more often on the move (at least 40 hours per week), and when they park it's generally at either the home of the driver or a designated lot somewhere not central enough to have high land value.

Personal cars are only in use about 10 hours a week on average (and median is probably 6 hours a week), meaning they need storage the other 96% of the time. But not just one storage spot: one at home, one at work, one at stores, one at restaurants. In the US there are about 8 parking spots per car, and that doesn't include non-restricted residential parking (your driveway or yard, as compared to an apartment complex with a set number of spaces). The main solution here is to reduce or abolish parking minimums because most of these parking spots are empty most of the time, and even big lots at malls aren't full during holiday shopping, and unfortunately even places whose clientele doesn't arrive by car are often mandated to provide parking. But for every personal car given up where the owner uses rideshares and taxis, they're saving the need for about 8 parking spots overall (ok, really like 3, and the other 5 should never have existed anyway).

In theory, rideshares would require commercial drivers licenses, and therefore a higher bar of competency than we see today. Changing from personal driving to rideshares would reduce crashes, injuries and deaths, as a larger percentage of all drivers would be better trained. But honestly, all driving requirements for everyone should be higher. It's terrifying how little competence is required to be a licensed driver.

Speaking from personal experience (so anecdotal): I live in a city that has atrocious public transportation and is unsafe to walk/bike in for much of the year (due to heat). My wife and I have one car, but we've had to use taxis and such when the need arises.

If we didn't have that option, we'd have to have a second car. There aren't really other feasible possibilities.

I'm reminded of the Herman Cain awards and websites like sorryantivaxxer, who chronicle the lives and deaths of people from covid through their Facebook posts. It's shows how misinformation helps kill people. They would rather believe and post Facebook memes than and actual facts or data. Sadly it always ends the same way. A family member sends a desperate plea for prayers followed not much later by a post stating that he loved one has passed away from covid, unvaccinated of course.
