Time to spring into action, people!

After a century of shooing away hunters, tending to trails, and helping visitors enjoy the wonder of the natural world, the guardians of America’s most treasured places have been handed an almost unimaginable new job – slowing the all-out assault climate change is waging against national parks across the nation. As the National Parks Service (NPS) has charted the loss of glaciers, sea level rise, and increase in wildfires spurred by rising temperatures in recent years, the scale of the threat to US heritage across the 412 national parks and monuments has become starkly apparent. As the National Parks Service turns 100 this week, their efforts to chart and stem the threat to the country’s history faces a daunting task. America’s grand symbols and painstakingly preserved archaeological sites are at risk of being winnowed away by the crashing waves, wildfires, and erosion triggered by warming temperatures. The Statue of Liberty is at “high exposure” risk from increasingly punishing storms. A national monument dedicated to abolitionist Harriet Tubman, who will be enshrined on a new $20 note, could be eaten away by rising tides in Maryland. The land once walked by Pocahontas and Captain John Smith in Jamestown, the first English settlement in the US, is surrounded by waters rising at twice the global average and may be beyond rescue. These threats are the latest in a pile of identified calamities to befall national parks and monuments due to climate change. Receding ice, extreme heat, and acidifying oceans are morphing America’s landscapes and coasts at a faster pace than at any time in human history. Come on, people. There is still hope, but for any good to come out of this, we need to stop polluting. That includes you, Big whatever it is you're poisoning our planet with.
