The Egyptian desert is set to host the African continent's first vertical forest. Italian architect and urban planner Stefano Boeri has unveiled designs for three buildings covered with pollution-absorbing trees and plants in Egypt's New Administrative Capital, which is under construction in the desert east of Cairo.

He is collaborating with Egyptian designer Shimaa Shalash and Italian landscape architect Laura Gatti on the trio of cube-shaped, seven-storey buildings that will comprise the development in the nascent city. The planted terraces will provide shade and habitats for wildlife. Image: Stefano Boeri Architetti The buildings will have p…

4 climate tipping points the planet is facing

Is our planet approaching a climate change cliff edge? Across the world, from the forests to the oceans, the consequences of humanity’s activities are being felt – and the effects could be catastrophic. Here are four key climate emergencies happening right now:

1. Arctic permafrost is melting Image: Nature Rising temperatures are destabilizing the frozen groundthat covers almost a fifth of the planet’s surface, and which has remained intact for millennia.

Permafrost binds soil, rock and sand in the ground. As it thaws, previously frozen organic matter in the ice decomposes, releasing harmful greenhouse gases – such as carbon dioxide and methane – into the atmosphere, with potentially devastating consequences for the planet. A dangerous cycle then ensues where released greenhouse gases fuel further climate change, causing more permafrost to melt.  Climate scientist Dr Boris K Biskaborn of the Alfred Wegener Institute, a polar and marine research organization, predicts melting permafrost…
