Climate scientists at a meeting of the American Association for the Advancement of Science this week were elated to hear that the United States and five other countries had agreed to work toward cutting pollutants other than carbon dioxide thought to cause about a third of current human-influenced global warming. After all, many of them [...]
Key Talks from a Global Science Summit
Earth Institute researchers spoke this past week at the annual meeting of the American Association for the Advancement of Science, a major global gathering of researchers from many disciplines. They covered topics from climate and human evolution to food security and tropical deforestation. Science editor Kevin Krajick covered the meeting from Vancouver, British Columbia.
Increased growing-season heat due to climate change in coming decades could push staple U.S. crops off a cliff, and cause world food prices to jump, a Columbia University economist told a press briefing at a top scientific meeting this week. In a panel organized by the American Association for the Advancement of Science, economist Wolfram [...]
With 7 billion people on the planet and some 40 percent of earth’s land surface already covered with croplands and pastures, the only remaining frontiers for agricultural expansion are dwindling tropical forests. Some see high-yield industrial-scale farming as a way to take the pressure off; the theory goes that if more produce can be grown [...]
Scientists often invoke climate as a possible factor in human evolution; but only recently have they developed the ability to get enough information about past climates and related fossil evidence to see any details. A half-dozen leading paleontologists and climate scientists discussed recent advances in a symposium this week at the annual meeting of the [...]
Since 2005, the Educational Global Climate Modeling Project has been downloaded 50,000 times, and adopted for teaching and research at hundreds of universities and other institutions.
Scientists at Columbia University’s Earth Institute will present important new work on global climate, air pollution, agriculture and other issues at the Feb. 16-20 meeting of the American Association for the Advancement of Science, in Vancouver, B.C.
