Glaciers and enigmatic stone stripes in the Ethiopian highlands
As the driver of global atmospheric and ocean circulation, the tropics play a central role in understanding past and future climate change. Both global climate simulations and worldwide ocean temperature reconstructions indicate that the cooling in t.....»»
Alaska"s top-heavy glaciers are approaching an irreversible tipping point
The melting of one of North America's largest icefields has accelerated and could soon reach an irreversible tipping point. That's the conclusion of new research colleagues and I have published on the Juneau Icefield, which straddles the Alaska-Canad.....»»
Microscopic defects in ice influence how massive glaciers flow, study shows
As they seep and calve into the sea, melting glaciers and ice sheets are raising global water levels at unprecedented rates. To predict and prepare for future sea-level rise, scientists need a better understanding of how fast glaciers melt and what i.....»»
How did the zebrafish get its stripes? Researchers are one step closer to finding out
Although zebrafish are much smaller and less famous than their terrestrial namesakes, the tiny fish possess a unique ability: They can rapidly change the color of their characteristic stripes from blue to yellow when they're distressed......»»
Researchers investigate changes in surface heat fluxes on sensitive areas for the slopes of Mt Everest
Under the background of global warming, the Mount Everest region has experienced evident climate changes. Glaciers and snow have been rapidly retreating in this region. These changes increase the rate of warming and water scarcity in downstream areas.....»»
