Now you know what climate change is, why it’s happening, and how it’s affecting us in Clark County. But how does this relate to the rest of the world? 

The choices we make in Clark County don’t just affect us—they make a difference for the whole planet. Climate tipping points are critical thresholds where small changes can cause big and lasting shifts in our climate. For example, as worldwide temperatures increase, permafrost is thawing in the arctic, releasing methane, a powerful greenhouse gas. The more this permafrost melts, the more methane is released into the atmosphere, trapping heat and speeding up climate change.
