If you’ve ever wanted to see the Himalayan glaciers, you might want to make a point of doing it soon, because every year they are looking less and less like they used to. In fact, last year one of the largest glaciers had receded by 22 metres, while other small ones disappeared completely. So what’s the biggest part of the problem? The 3km thick cloud of pollution that’s hanging over Asia and magnifying the solar heating by almost 50% in the surrounding areas. The repercussions of ignoring this catastrophe will be beyond terrible, so it’s important to do something now, if it’s not already too late.
