Saw this piece on CNN. Not sure how accurate the reporting is, but I do know there's severe water shortage where I live in India. In summer, many apartment buildings pay good money to have water hauled in. The scary thing is, I see the US on the map of nations facing acute water shortage by 2040! Many poorer nations and people may not be able to afford to do that. What do you folks think?

Global warming and water shortages in two decades...
Yet banks are still lending...

Water is always a problem here in Australia.
It doesn't matter what policies the government is touting, if we have no water: that's it.
Yet it is never taken into consideration when discussing migration, we don't have enough water now for the people here, agriculture etc so how on earth can we sustain more people?
We are the driest continent on earth but that simple fact doesn't seem to enter the minds of any of the political parties.

It is another thing pointing to our Lords return because the world cannot go on like this.

My students have done some work on this: Desalination. Most countries have massive coastlines. Saudi Arabia is the largest producer/consumer of desalinated water. Should the rest of us emulate that model (or is it just too expensive and would kill all aquatic life)?

Hi just wondering what do you teach? Econ?

Desalination will work in the short term; I am not a biologist, so the implication to sea life was something I didn't realize until now. But I would imagine it would definitely perturb the system to the point of a chain reaction.

We would need to desalinate a fourth of the Atlantic to satisfy the world needs for the next 100 years - if the water shortage is as severe as thought. But, if we stop cutting down trees we will have more filtered water cleaned by UV radiation, and gently dropped from the sky.

I think it will come down to a global maturity issue:

stop building cities meant for profit instead of longevity (i.e. wood vs stone houses)

stop hoarding the majority of resources for the super-rich only (there are plenty of resources for 100 billion people; we just cluster in cities where we leech the land an resources exponentially - giving the impression of overpopulation)

Stop allowing leaders to continue razing land through wars for profit, and telegraphing the cost onto the people

Get over racism to the point where it can be confronted, resolved and ultimately reverted to simple prejudice (very different from racism).

Learn trades of self-sufficiency.

Eliminate fiat-based currency systems
If the world can do those basic activities of maturity, then we would realize how rich we all are, and we wouldn't have to connive and scheme just to get $1 more than the next person.

Straight desalination is relatively expensive and there is some concern of effects of returning the salt back to the ocean. Of course, technologies do get better and cheaper and when your water runs out you quickly notice that you would rather use your money to buy water than some other commodities in your life so even if expensive this will probably be commercially viable.

The more permanent method would probably be the combination of different recycling and desalination techniques while avoiding the use of unnecessary water. Israel had been a leading actor on this for a while now.

Mechanical Engineering. Interest in Economics is as an investor and from an investing point of view. Geo-politics (especially US politics, as I may return) from a Christian, socioeconomic perspective. Thanks:).

It's probably different in India, but here we waste tremendous amounts of water. Car washes, watering crops and lawns in the desert where no non-desert plants should be, golf courses, taking showers every day even though you haven't sweated in 6 months, flushing every single time. I don't particularly care if a bank has a nice green lawn. So there's no point in complaining about water shortages if you just throw it away.

I think climate change will alter any map based on projecting use by population based on old rainfall averages.

We are getting a lot more rain. In fact so far this year to date through May has had the most rain of all 125 years of data for the lower 48 states of the U.S.

the east coast of America is getting a lot of rain. That’s not necessarily a good thing as it tends to leach nutrients from the soil.

From the link.

“We’re trying to work with Mother Nature. She’s just not cooperating very much right now. We get close, and then wham we get another rain,” Kestel said.

Nothing could be further from the truth. Corn and soybean farmers work against nature. In fact such farming practices contribute heavily to atmospheric co2 as well as crazy rainfall patterns.

India also faces increasingly deadly seasonal heat waves that kill thousands each summer.

Are parts of India becoming too hot for humans?
