A new analysis of a 481-meter tsunami generated by a landslide in Alaska’s popular Tracy Arm Fjord last summer describes how glacial retreat, due to global warming, primed the fjord for the colossal wave and what, if any, warning signs preceded it.
Human-caused warming is responsible for increasing the risk of a glacial outburst flood from Peru’s Lake Palcacocha, threatening the city below. This study is the first to directly link climate change with the risk of flooding from glacial lakes, which are growing in number and size worldwide.
A ºÚÁϳԹÏÍø study addresses controversies over the cause of mountain glacier retreat, and finds that for most glaciers the observed retreat is more than 99 percent likely due to climate change.
