Is this the key to afforestation projects in arid or desert areas ? As hundreds of billion of trees have to be planted over the next decades to avert climate change, the question is of tremendous importance. As Cleantechnica reports, the Gulf state of Qatar is experimenting an interesting project – the Sahara Forest Project… Continue reading Could we reforest the Sahara desert ?

Indeed this geoengineering idea would absorb eight billion tons of carbon a year. But we shouldn’t forget that… Continue reading An interesting geoengineering idea
We have seen it previously, the Amazon Rainforest could become a desert because of deforestation and climate change. As I noted in May a three degrees Celsius increase would destroy it by up to 75 percent. But could global warming help the Sahara region becoming green again ? To National Geographic it could be the… Continue reading Could the Sahara desert become green again ?
