#43Hot take on HN, but techno-optimism sounds so stupid when it comes to climate change... You can't engineer macro climate/ecology, since capital has no interest in human and it's surrounding environment balanced cohabitation.
Climate also doesn't change in macro over a lifetime. It's very real, but the notion that it's changing over a 5 year period is nonsense. things aren't "shutting off".
Looking back at the amount of snowfall I saw as a kid and the amount of snowfall I see now in my 30s, or at the number of hot summer days ... I find it hard to claim that climate is not changing over a lifetime. 20 years isn't even a lifetime, that's like 1/4th of a lifetime
Maybe climate is more stable wherever you live

#45I think climate change is a compelling crisis but I find these types of “could maybe happen according to some models” type of catastrophic scenarios a little frustrating because they soak up a lot of attention with scary headlines, reinforcing hopelessness in those who care while providing ammunition to skeptics when the catastrophe doesn’t materialize. It’s also easy to question methodology for anyone who has done a…
The risk was 5% and is now above 50% according to experts in the field.
Given the significant consequences this is worth paying attention to.

In the past, these climate models were mostly on the conservative side. So I would stop questioning them and ask for more actions to take toward implementing existing climate solutions.

I am old enough to have witnessed how the climate has completely changed in Europe, where I live. In the same place where I live now, when I was young there was permanent snow cover for 3 to 4 months. During the last 10 years, there have been years with no snow and in the others a little snow has been present for 3 or 4 days of a year, when it melted the second day after falling. I have not used again my winter boots…
Better keep those winter clothes in case the current shuts down.

#50“Scientists” have been warning the world about this since Stommel issued his paper in 1961: https://tellusjournal.org/articles/10.3402/tellusa.v13i2.949... It’s going to shut down The ice caps and antartic ice are going to melt entirely The Gulf Stream is going to collapse Global emissions have skyrocketed with no brakes since then 1.5C target was a joke. 2.0 target is a joke. There is no world where humans can coord…
The archeological and geological records strongly suggest we've been down this road before. There's as much arrogance in assuming we can prevent this, as there is in assuming we caused it (perhaps hastened it). Best use of national or global resources is preparing for the outcome, not trying to prevent it.
Tough to tell exactly what you’re referencing, but you might be thinking about the Paleocene–Eocene thermal maximum, which was a natural increase in carbon in the atmosphere that led to higher temperatures. So, in some ways very similar to what we’re seeing now, but if my understanding is correct, even the PETM which was “dramatic” on a geological timescale took thousands of years to ramp up, and played out over 200,000 years. What we’re seeing now is happening much quicker, and is highly correlated with human influence.
