In "Today's Sobering News", a report on ongoing climate talks in Incheon, South Korea:
Climate scientists are struggling to find the right words for very bad news
Even if the world converts it's entire fleet of ~1.1 billion actively operating automobiles to electric tomorrow, it might already be too late to stop significant climate change. We have something like a decade to reduce global carbon emissions by around 40% if our goal is merely to keep global warming below 1.5 C which is the threshold set to prevent island nations like Micronesia from drowning in the ocean.
Things are desperate enough that they are talking openly of attempting worldwide carbon sequestration, which no actual technology exists that can do that right now and even if we developed it, we would have to avoid the "Snowpiercer Scenario" where a misguided sequestration resulted in a new Ice Age instead.
Random ironic thought of the day: The movie Snowpiercer was directed by South Korean director Bong Joon-Ho, where these climate talks are currently ongoing.
