Global Warming Spreads Deserts, Shrinks Arable Lands and Floods Cities

China's Growing Desert

Spread of Deserts Requires Quick Response

Enough fertile land could turn into desert within the next generation to create an "environmental crisis of global proportions," large-scale migrations and political instability in parts of Africa and Central Asia unless current trends are quickly stemmed, a few United Nations report concludes. Here's a link to Elisabeth Rosenthal's article in today's NY Times.

Global Warming Also Likely to Endanger Coastal Cities the World Over

Because glaciers are melting faster than previously believed scientists say that sea levels may rise by three feet by the end of the century, flooding coastal areas and cities in the United States and in other countries around the world.

We have the capability and the technology to make deserts that can support life. We need to dam, and build waterways from areas that get too much rain and route them to those that don't get enough rain.

We can improve on the randomness of nature.

There is no global warming. It was a hoax.

O.D., There will be multiple effects from climate change, some positive and others negative. It will strain our ability to adapt.

vrajavala, you're entitled to your opinion. You could be correct, but you are in a tiny minority of knowledgeable people who don't accept the best climate science.

I was responding to the main topic of deserts, and how we could irrigate them.

If there is global warming then it can only be solved globally, and not just in CA or the US.

That's true. The science is pretty clear. The problem is one of global education and politics. I heard on NPR just this morning that there would be a huge loss of arable land (I don't remember the percentage) for each degree of increase in global temperatures. And a five degree increase would be devastating.

I guess we should start making plans now.

Thanks

Yep. It doesn't look as if anything big is going to get done in the near future.

As a result of recent calculations that take the changes in the rate of glacier melting into account, many scientists now say that sea level is likely to rise perhaps three feet by 2100 — an increase that, should it come to pass, would pose a threat to coastal regions the world over.

Head for the high ground!

And by next Monday the sea level will have increased by 100 feet! You forgot to put that in your headline.

I don't know from where you get your information, but the geological record shows that a hotter earth, 5 to 10 degrees means, with a similar continental configuration as today, a greener earth.

As a matter of fact, it looks like all over the world, deserts are shrinking as temperature rises. It's no surprise that the horrible famines that strook the Sahel zone, were mostly in the 60s and 70s, which where quite colder than today...

Stop spreading FUD and stick to the facts, please.

I'm not a scientist, but I get my information from a wide variety of reliable sources that report on climate science. Where do you get your information?
