A whopping 125 lakes in the Arctic have disappeared in the past few decades, backing up the idea that global warming is working fiendishly fast nearest Earth's poles. Research into the whereabouts of the missing water points to the probability that permafrost underneath the lakes thawed out. When this normally permanently-frozen ground thaws, the water in the lakes can seep through the soil, draining the lake, one researcher likened it to pulling the plug out of the bathtub. When the lakes disappear, the ecosystems they support also lose their home.
