Indicators of a Warming World, 30 December 2010. This one is a graphic summary of just some of the evidence for global warming. Signs of warming are being found not only all over the globe but in many different systems. Ice sheets are shrinking. Tree-lines are shifting towards the poles and up mountains (i.e., to cooler regions). Glaciers are retreating. Spring is coming earlier. Species are migrating to cooler regions. And so on. John Cook

Tree-lines are shifting towards the poles and up mountains (i.e., to cooler regions). Glaciers are retreating. Spring is coming earlier. Species are migrating to cooler regions. And so on…
