Summary of Article: Lake Poopó, Bolivia's second largest lake, is now just a dry, salty expanse. Even after surviving decades of water diversion and El Niño droughts, Lake Poopó basically disappeared. The lake was perched 12,140 feet above sea level in the dry Bolivian high plains. But, climate change is what topped it all off. Each decade, on average, since 1985 the lake warmed .41 degrees Fahrenheit, or 0.23 degrees Celsius.
