Scientists warn that a crucial ocean current could collapse, altering global weather (www.latimes.com)

Scientists are sounding the alarm that a crucial component of the planet’s climate system is in gradual decline and could one day reach a tipping point that would radically alter global weather patterns.

The Atlantic Meridional Overturning Circulation, or AMOC, is a system of ocean currents that circulate water in the Atlantic Ocean like a conveyor belt, helping to redistribute heat and regulate global and regional climates. New research, however, warns that the AMOC is weakening under a warming climate, and could potentially suffer a dangerous and abrupt collapse with worldwide consequences.

“This is bad news for the climate system and humanity,” researchers from Utrecht University’s Institute for Marine and Atmospheric Research wrote in a new study published in the journal Science Advances.

While I agree that remote work is positive for the climate 1 )I think you overestimate the number of jobs that can be done remotely. 2) Emissions shift from transportation to home climate control, which may be a net positive in most cases but not necessarily.

It is a start but we need bigger policy changes than that for it to "sort itself out"

I also feel this is may be good but could not be, the number you didn’t give is too large, the benefit would be good but might not be, and this simple step should be replaced with large complicated ones.

Transportation already accounts for more carbon emissions than electricity generation. Green Energy is phasing out fossil fuels in most places albeit slowly. Unless you live somewhere with a fairly extreme climate you don't really need to use that much energy on climate control. I live in the Arctic and only run one heater in the whole apartment and only intermittently. AC uses less electricity than heating. The laptop I use uses the same amount of electricity whether I use it at home or the office. And I realise that there are many jobs that can't be done from home but it's ridiculous to not allow office workers to work from home.

Many of my colleagues burn a liter of diesel a day commuting to work. And that's in a place where you don't idle in traffic for an hour. If anyone who had an office job in LA for example just wasn't in traffic, you can bet your ass the air would be cleaner.

And yes you're right about needing wide scale policy changes. One of the big ones would be investing in high speed rail. Way more environmentally friendly than either flying or driving and more comfortable. And for many journeys doesn't actually take longer than flying. When you consider staking a half hour shuttle bus to the airport, waiting a half hour to get through security, hanging around at the gate, waiting for luggage, shuttle bus from the airport at the other end. It's actually quicker to take the train from London to Paris than it is to fly, more environmentally friendly, but still costs more.
