Some very smart "rocket scientists" seem to think so.

As cited on NASA's Global Climate Change page:

Press Release: Could planting trees in the desert mitigate climate change?

European Geosciences Union -- 31 July 2013

As the world starts feeling the effects of increasing atmospheric carbon dioxide and consequent global temperature rise, researchers are looking for a Plan B to mitigate climate change. A group of German scientists has now come up with an environmentally friendly method that they say could do just that. The technique, dubbed carbon farming, consists in planting trees in arid regions on a large scale to capture CO2. They publish their study today in Earth System Dynamics, a journal of the European Geosciences Union (EGU).

Carbon farming addresses the root source of climate change: the emission of carbon dioxide by human activities,” says first-author Klaus Becker of the University of Hohenheim in Stuttgart.

Nature does it better,” adds Becker’s colleague Volker Wulfmeyer, “if we understand and can make use of it in a sustainable manner.”

When it comes to sequestering carbon from the atmosphere, the team shows that Jatropha curcas does it better. This small tree is very resistant to aridity so it can be planted in hot and dry land in soil unsuitable for food production. The plant does need water to grow though, so coastal areas where desalinated seawater can be made available are ideal.

But would they end up doing with all those carbon-sequestering crops of Jatropha curcas? Perhaps those Geo-scientists have a few ideas on that ...

About Jatropha Curcas --

Jatropha Curcas is a non edible oil crop predominately used to produce bio-diesel.

In addition to bio-diesel production, the by-product of Jatropha Curcas' trans-esterification process can be used to make a wide range of products including high quality paper, energy pellets, soap, cosmetics, toothpaste, embalming fluid, pipe joint cement, cough medicine and as a moistening agent in tobacco.

The Jatropha Curcas seed cake which is the waste by-product of the bio-diesel trans-esterification process can be used as a rich organic fertilizer.

Jatropha Curcas grows best on well drained soils (pref PH 6-9) with good aeration but is well adapted to marginal soils with low nutrient content.

Jatropha Curcas grows well with more than 600 mm rainfall per year and it can withstand long periods of drought. The plant sheds its leaves during a prolonged dry season.

Well, what do you think?  Is this an idea with promise, or an idea with ever-more problems?

Remember eventually, we got to do something!

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.

You can add a private note to this diary when hotlisting it:
