Highlighted by the stupidity of not buying directly from Russia at normal prices but instead buying the same hydrocarbons extracted by Russia from war washing third parties like China and India who resell Russian hydrocarbons to those who for political reasons can’t buy directly but can buy indirectly at inflated prices!! It’s the height of stupidity.

As far as I can tell, e.g. (1), the EU does not get gas from China or India. (1) https://markets.businessinsider.com/news/commodities/europea...

While it's absolutely true there is a confluence of factors here (eg glacial melt, heat wave and a depression) and that these events are more likely with global warming, I'm disappointed this article didn't cover another important factor: dams. Flooding used to be a much bigger problem in the Western United States and it was solved with dams. Yes, there is thd risk of dam failure but we're weighing up the real and pr…

Dams destroy ecosystems, reduce biodiversity and often just silt up. A related but far better idea is to encourage water retention on a far bigger scale by building johads or berms everywhere. See the Paani foundation's work in next door India.

its possible we didnt look at the same flood map or i'm looking at it wrong, but the way i read it it says that >5% of the country is flooded. Thats beyond the scope of dams to handle i believe.

I think it's worth pointing out that the impacts of climate change are often presented as singular effects: rising sea level, warmer summers, increased drought, etc. But as we can see here there is also a very strong interaction effect between all of these (and it tends to magnify the issues rather than having them cancel out). This is also why many major climate reports tend to inherently be on the conservative side…

Pretty disheartening to see the downvotes in a forum like hn which are supposed to be informed about these things. If people that are supposed to be able to critically assess data and have access to as much information they need to verify any claims come to the conclusion that you are full of shit, what hope is there to educate grandpa screaming at the wokes on the street.

You're right it seems. Here's a non-paywalled article https://news.yahoo.com/china-reselling-natural-gas-energy-14...

I read someone else suggest Permaculture as a way of mitigating some of the affects of monsoons in these types of areas. Does anyone have any evidences of such a thing working?

Sounds ridiculous on its face, and that is as a practitioner of permaculture. I couldn't really get my head around how it could possibly make even a slight dent against the massive flooding witnessed here.

The more water that is retained on the property, the less that is available for entering streams.

It is difficult to get a man to understand something when his startup idea depends upon his not understanding it.

also missing is yet another aspect of a very complex system - parched soil has lower ability to retain water. These floods follow an intense heatwave during which large swathes of pakistani soil dried up. Come the rains and you have a massive problem.

Like you say, this is just the beginning. If floods like this happen in the Indian plains - and they will - the human and social costs will be immense.

Lots of small water retaining walls and pits makes it so it doesn’t run off and accumulate in some low central area.
