Can Sahara be forested?
The Sahara Desert is one of the world’s largest and driest deserts. The mission of the Sahara Forest Project is to turn the arid desert into a self-sustaining open greenhouse that will draw water from the atmosphere and energy from the sun.
What would happen if you irrigate the Sahara?
One idea is to plant crops and trees, and then pump desalinated water from the coast of the Sahara to irrigate them. As the trees began to root and stabilize, the soil would be replenished with needed nutrients, rainfall amounts would increase, and the overall temperature of the Sahara would cool by 8°C (14.5°F).
What caused the Sahara to form?
Green Sahara: African Humid Periods Paced by Earth’s Orbital Changes. Paleoclimate and archaeological evidence tells us that, 11,000-5,000 years ago, the Earth’s slow orbital ‘wobble’ transformed today’s Sahara desert to a land covered with vegetation and lakes.

What if we flooded the Dead Sea?
Nevertheless, the Dead Sea Depression, flooded with sea water, could hold 1,500 cubic kilometres of water. Filling the sink, however, would eliminate some rather nice olive groves and would submerge important historical sites – including Jericho, a town of 20,000 and perhaps the oldest community on Earth.
Are deserts next to oceans?
Cold ocean currents coupled with a mountain range next to the ocean make deserts. A good example is Atacama desert, which is between the Pacific Ocean and the Andies mountain range, and happens to be the dryest place on earth. Most deserts lack drinkable water.
What’s under the sand at the beach?
Often, underneath the loose sand of a beach is a layer of hard, compacted sand, which could be on its way to becoming sandstone if the necessary cement, pressure and heat ever appear — and if is not eroded by severe storms.
