>Even if greenhouse emissions stopped overnight the concentrations already in the atmosphere would still mean a global rise of between 0.5 and 1C. A shift of a single degree is barely perceptible to human skin, but it’s not human skin we’re talking about. It’s the planet; and an average increase of one degree across its entire surface means huge changes in climatic extremes.
>Six thousand years ago, when the world was one degree warmer than it is now, the American agricultural heartland around Nebraska was desert. It suffered a short reprise during the dust- bowl years of the 1930s, when the topsoil blew away and hundreds of thousands of refugees trailed through the dust to an uncertain welcome further west. The effect of one-degree warming, therefore, requires no great feat of imagination.
>“The western United States once again could suffer perennial droughts, far worse than the 1930s. Deserts will reappear particularly in Nebraska, but also in eastern Montana, Wyoming and Arizona, northern Texas and Oklahoma. As dust and sandstorms turn day into night across thousands of miles of former prairie, farmsteads, roads and even entire towns will be engulfed by sand.”
>What’s bad for America will be worse for poorer countries closer to the equator. It has beencalculated that a one-degree increase would eliminate fresh water from a third of the world’s land surface by 2100. Again we have seen what this means. There was an incident in the summer of 2005: One tributary fell so low that miles of exposed riverbank dried out into sand dunes, with winds whipping up thick sandstorms. As desperate villagers looked out onto baking mud instead of flowing water, the army was drafted in to ferry precious drinking water up the river – by helicopter, since most of the river was too low to be navigable by boat. The river in question was not some small, insignificant trickle in Sussex. It was the Amazon.
