It’s hard to believe how many visitors to HN are climate science deniers. This is equivalent to claiming the earth is flat, denying the value of vaccines, or arguing that we didn’t really land on the moon.
With measured change in C02 the past 60 years[0], how can we expect the system to behave the same? In my lifetime I will breathe air with C02 levels of 480ppm. Throw in the high sea temperatures [1][2] if you would like some bonus content.
Idk what it means for us on the ground. 90% of the doomerisms haven't gone anywhere - but this is worth keeping an eye on. Who knows, maybe in 3 more generations we'll hit 800ppm C02 and experience cognitive decline[3] before we have to worry about the climate system getting funky :)

What am I supposed to do about any of that? How am I supposed to believe in the future if this is still the early days of climate change with who knows what new horrors to come in a decade or two?
And so we go on because what else can we do? Mostly I’m just glad I never wanted to have children because I can’t imagine what it is like for them as they grow up and realize what awaits them.
