To what extent was the runway there "built" as a permanent installation, vs being an ephemeral phenomenon that is refreshed season by season?

- yodon 4y agoIt requires maintenance but it's not like the ice is going to melt in the South Pole "summer."

- tomrod 4y agoSeems like I just read on HN an article on Antarctic weather patterns (but not ice floes) are self-reinforcing.
- matthewdgreen 4y agoThat was one model. I sure hope it’s correct. If there’s one lesson I’ve learned over 30 years of following this topic, it’s that things very rarely break in our favor.

- ipaddr 4y agoAfter reading endless books from the 70s/80s spreading the fear of entering a new ice age, going through acid rain and a hole in the ozone layer you would be surprised by how quickly important things change.

- KennyBlanken 4y agoAcid rain was an enormous problem, and is no longer because a large number of countries passed emissions regulations to curb emissions that caused it. Places like London used to have so much air pollution, going outside on a rainy day was hazardous to your health because the fog was toxic. The hole in the ozone layer is repaired because a large number of countries passed regulations prohibiting many uses of ozone-depleting substances, and consumers voted with their wallets as well. Unfortunately, we're not seeing anywhere near the commitment required to slash CO2 emissions, and a huge amount of damage is already done. It's not just climate change, but in the last fifty years, something like 2/3rds of wildlife has disappeared. In barely one generation we've wiped out two thirds of wildlife. That is mind boggling and if it doesn't count as a mass extinction, I don't know what does.
- fomine3 4y agoHad consumers voted with their wallets for banning Freon? I don't know. Isn't it just a successful of developing alternatives and regulation? Maybe some consumers voted with their wallets for fuel economy car (thus lower CO2 emissions)
- matthewdgreen 4y agoWe’re above 1 degree C and heading towards 1.5 very quickly, with rising methane levels from multiple sources. This isn’t the ozone hole. I wish it was.
