The ‘bird’ has flown! Voices are raised in celebratory cheers from the southernmost continent to across the U.S. Our first ALAMO float is deployed! Now we can begin to answer some of the big questions on this mysterious ice/ocean interface.
A new study documents evidence of a massive release of carbon from Siberian permafrost as temperatures rose at the end of the last ice age.
The first of six ALAMO floats parachuted into the Ross Sea off Antarctica to begin profiling the water in a check for areas where warmer than normal water could put the Ross Ice Shelf at risk.
Scientists at Columbia University’s Earth Institute will present important findings at this year’s meeting of the American Geophysical Union, the world’s largest gathering of earth and space scientists.
We do not know enough about our planet and the impact of human technology on its basic systems. It is beyond idiotic to think we can grow our population and consumption this much, this quickly, and have no impact. But it is also foolish to overstate what we know and ask policymakers to invest trillions of dollars on impacts we have not yet seen. Scientists need to be encouraged and funded to present facts, projections and options.
The Antarctica Peninsula has been referred to as Antarctica’s third ice sheet. Following behind the East and West Antarctic ice sheet in size, one might be inclined to minimize its importance in the effects of melting Antarctic ice, on changes in sea level and other impacts, but that would be an imprudent mistake. The peninsula is Antarctica’s most northern spit of land; like a crooked finger it stretches out beckoning towards the southern tip of South America and her warmer climate.
Artist Michelle Rogers is painting her latest work, an 8x10ft interpretation of Botticelli’s The Birth of Venus, at the International Research Institute for Climate and Society. She wants her discussions with scientists to help inform her work.
Due to warming climate and increasing human exploitation, far northern forests and the tundra beyond are undergoing rapid changes. In northern Alaska, scientists from Columbia University’s Lamont-Doherty Earth Observatory and other institutions are studying the responses of trees at the very edge of their range.
In northern Alaska’s Brooks Range, the earth as most of us know it comes to an end. The northern tree line-a boundary that circles all of earth’s northern landmasses for more than 8,300 miles, and forms the planet’s biggest ecological transition zone–runs through here. Scientists from Columbia University’s Lamont-Doherty Earth Observatory are studying how climate may change it, and the tundra beyond.
For those who favor strong action on climate change, the election of Donald Trump is creating plenty of anxiety and concern. Will Trump set our efforts to curb climate change back? How can those who are concerned about climate change best fight back?
