All the Beijing snow is human-made

Climate variability has forced the Winter Games to be virtually 100% reliant on artificial snow -- part of a trend that is taking place across winter sports venues around the world.

Just one of the 21 cities that have hosted the Winter Olympics in the past 50 years will have a climate suitable for winter sports by the end of the century, a recent study found, if fossil fuel emissions remain unchecked.

As the planet warms and the weather becomes increasingly more erratic, natural snow is becoming less reliable for winter sports, which forces venues to lean more on artificial snow.

But it comes at a cost: human-made snow is incredibly resource-intensive, requiring massive amounts of energy and water to produce in a climate that's getting warmer and warmer. Elite athletes also say that the sports themselves become trickier and less safe when human-made snow is involved.
