We all know that climate change can generate great debate in the United States. But what about the rest of the world?
Sea level rise from melting ice sheets in Antarctica and Greenland threaten catastrophe for coastal cities within decades unless strong measures are taken to reduce CO2 emissions from the use of fossil fuels, argues climate scientist James Hansen. Hansen’s warnings about the dangers of climate change are not new, but a new paper written by… read more
If you take a look at nearly any satellite image of clouds in the tropics, you’ll notice that the clouds tend to be organized into clusters. One specific type of cloud organization called “self-aggregation.” Self-aggregation is the tendency of tropical clouds to spontaneously clump together, solely due to interactions between the clouds and the surrounding environment.
A team of biologists and agronomists has identified genomic signatures in plants indicating they are resilient to stresses such as drought or toxic soils. The multi-year study, expected to help developing-world farmers, was done with sorghum, one of the world’s most common crops.
Computer scientists at Columbia University will work with oceanographers to understand what has caused an unusual plankton-like species to rapidly invade the Arabian Sea food chain, threatening fisheries that sustain more than 100 million people.
The Pope’s Challenge on Climate Change
Pope Francis’s broad-ranging encyclical warns that we are destroying our common home and face an immense and urgent challenge to protect it. But it goes far beyond just the subject of climate change, calling for a holistic and sustainable future.
While the ice sheets on West Antarctica and the Antarctic Peninsula are usually the ones to make the news in relation to climate change, recent studies have documented transformations that are taking place on the East Antarctic Ice Sheet as well. On the continent as a whole, large areas of ice have already melted and this trend shows no sign of slowing, meaning the implications for global sea level rise in this century could be more dramatic than earlier projections anticipated.
Glacial earthquakes are produced as massive ice chunks fall off the fronts of advancing glaciers into the ocean. A new study of the quakes’ mechanics may give scientists a way to measure ice loss remotely and refine predictions of sea-level rise.
Climate change has many asking if the days of being able to summit the world’s highest peak are numbered.
In a study published last week, Lamont post-doctoral scholar Heather Ford and coauthors used 4 million-year-old fossils from the Pliocene to reconstruct the physical features of the Pacific Ocean that would have shaped the environment during a critical juncture in Earth history.
