Re: Orange juice exists due to climate change in the Himalayas millions of years ago
#2The article mentions that the himalayas grow by about 1cm per year, and that it has been growing for millions of years. Wikipedia says it is more like 5mm/year.
So I'm assuming a growth rate of 5km/My, while Everest is only about 9km.
I understand what has been limiting height: gravity, rock strength, erosion, sinking into the mantle... But since there is growth now, obviously these processes are not in short term equilibrium. So how does this play out? Are there apocalyptic landslides every million years or so? Or just periods of growth alternated with periods of shrinking?

Punctuated equilibrium[1] — growth followed by sudden collapse — could be the umbrella term for the scenarios you are thinking of.
The phenomenon, originally from biology, shows up in sandpiles and avalanches as well; it could explain the growth (or lack of it) of mountains too.

For any particular mountain or mountain ranger there could be a number of processes, some of which may dominate for periods of time.
It could be slow / fast growth followed by slow / fast sinking / decay / collapse / asteroid impact / weathering.
I image there have been a number of sequences that have played out in various locations over time.

Not to answer your question exactly, but you may want to look into the works of https://en.wikipedia.org/wiki/William_Ruddiman
He has hypothesised that the tectonic uplift and weathering of the Himalayas has had profound impact on Earth's climate and atmosphere.

Why are you assuming a linear growth model for it in the first place?

#7Easily the worst thing you can drink on a regular basis. I use to think OJ was healthily and drank it a lot. I stopped completely at some point a year or so back and over about 6 months lost over 20 pounds of weight I could never lose, even though I play hockey 2-3 days a week and workout pretty much every day. I went from 205, my college hockey weight, to 180 now.
There is a reason they use to give you a tiny juice glass for OJ, and I'd bet even that is pretty terrible for you daily.

#8The region never ceases to amaze. I have spent most of my adult life around Yunnan, and I am writing an ancient history of the area. It has significant historic links with India, Tibet, Southeast Asia, Central Asia, Iran, Vietnam and China. It's the most biologically, culturally, linguistically, climatically and culinary diverse area of China and possibly the world. If you find yourself with time, cycle touring the area is one of the best things you can do anywhere on the planet.

The headline may read that way, but the article doesn't.
