The record cancelation of flights out of Phoenix, Arizona in the summer of 2017 due to unusually high air temperature is the reason I picked my doctoral research topic on the impacts of climate change on aviation. Now, Phoenix set another unfortunate record: 100 straight days of 100°F (~38°C) or greater heat, beating the previous streak by 3.5 weeks. The death toll will likely be in the hundreds this year (it was 645 last year for the whole Maricopa county). But of course, this does not include the death of local fauna and flora, which is silent until we find our food chains disrupted. https://www.washingtonpost.com/weather/2024/09/03/phoenix-100-degree-temperatures-record/

do you have an opinion on carbon capture/direct air capture? how real is it?

It's real, but impact is nothing compared to preventing emissions in the first place. Even natural carbon capture suffers from heat. We are asked to plant trees, but heat makes them absorb less carbon... So the more we emit the less our carbon capture is working. If it require to build industrial plants to absorb emission from industrial plants... Not sure we can get out of it easily... The main way is to emit less, meaning producing less, meaning less consumption of energy, goods, travels, meat, ... Some people already do that, some people are willing to do it, but most people don't even consider it and some even oppose hard on changing their way of living.

thanks for the answer I thought maybe engineered carbon capture could scale a lot more than trees (given clean energy to power it) and thus could offset the emissions that are too hard to stop while the clean energy transition happens

Also, there's a big paradox here about transitioning: if we find ways to absorb GHGs to help until we find a way to reduce emissions, there's no reason to reduce emissions as we can absorb them. So, many people who would prefer to keep emitting (and keep non viable lifestyle) are going to believe in technology being able to solve the issue. But it really is a matter of scale, it's like emptying the sea with a tea spoon actually.

For a large part, we already know how to reduce emissions. For the first time in history, we have a Tragedy of the commons situation at the scale of the entire humanity.
