Wildfires in the US and Africa, tropical storms, and Bolivian salt flats are among the images captured by Nasa and the ESA last month
Pakistan’s Makran coast meets the Arabian Sea where the dry terrain contrasts sharply with the water. Sometimes coast and water overlap and sediment pours into the sea. Once river water and sediment reach the ocean they are swept along by currents. Inland, the landscape is rugged. Narrow valleys provide pastures for sheep amid the desert.Continue reading...
In the USA, the southeastern states are most vulnerable to the costly impacts from human-caused climate change
Humans are causing Earth’s climate to change. We know that. We’ve known it for decades. Okay so what? The follow-up questions should be directed to what the effects of warming will be. What will the costs be to society, to the natural biosystem, and to human lives? Let’s be honest, if the consequences of warming are not large, then who cares? But, if the consequences are severe, then we should take action now to reduce the warming. This really comes down to costs and benefits. Are the benefits of reducing emissions greater or less than the costs?
But there is a nuance to the answer. The costs are not uniformly distributed. Some regions will suffer more and other regions will suffer less. In fact, some regions will actually benefit in a warming climate. We understand that the world is interconnected and costs will inevitably be shared to some extent. But it is clear we won’t all suffer the same.

Under a moonless, starless, benighted sky, head torches were switched on and we struck out across the riverside meadow. We had walked for several sure-footed minutes along a closely grazed towpath where white yarrow rosettes glowed like solar garden lights. The only hazards on that firm ground had been the nearly invisible giant plates that I stepped on and found to have hard crusts and soft hearts.Continue reading...
