“The fate of the Hindu Kush Himalayan glaciers has been a topic of heated debate due to their rapid melting and retreat. The underlying reason for the debate is the lack of systematic large-scale observations of the extent of glaciers in the region owing to the high altitude, remoteness of the terrain, and extreme climatic conditions. Here we present a remote sensing–based comprehensive assessment of the current status and observed changes in the glacier extent of the Hindu Kush Himalayas. It reveals highly heterogeneous, yet undeniable impacts of climate change.”

“Levels and surface areas of lakes are indicators of climate change and climate variability. Information of the surface extent of all the lakes on the northeastern Tibetan Plateau and its adjacent areas was extracted from Landsat images obtained in the 1970s, the 1990s, around 2000, and 2010 and developed a lake spatial database. The dynamic changes of the number and lake surface area in the past forty years were analyzed. ”

Science vs. politics in Chile

“Chile’s scientific community fractured over how to define credible science. Divisive and decisive issues included the source of funding, ethics, access to resources, and being local. Although some scientists and non-scientists used boundary work to try to affirm the authority of science, no stable map of scientific credibility resulted from these efforts. Chile’s new democracy is more plural than its recent military dictatorship but still lacks adequate spaces in which to negotiate what counts as credible science. These experiences highlight the need to better understand how science fares through regime transitions and what it contributes to emerging democracies.”

What a great looking place, never been to a glacier, but someday, well worth the risk of getting eaten up by a crack in the glacier!
