Landsat thermal sensor lights up from volcano's heat
As the Landsat Data Continuity Mission satellite flew over Indonesia's Flores Sea April 29, it captured an image of Paluweh volcano spewing ash into the air. The satellite's Operational Land Imager detected the white cloud of smoke and ash drifting northwest, over the green forests of the island and the blue waters of the tropical sea. The Thermal Infrared Sensor on LDCM picked up even more.

Satellite observations one key to climate models
In the 1960s, climate science took a quantum leap forward when researchers at the Geophysical Fluid Dynamics Laboratory in Princeton, N.J. developed the first computerized model of Earth’s climate that could account for both atmospheric and oceanic processes. For the first time, scientists could see how the complex interactions between the ocean and the atmosphere influenced global climate. The model was the basis for the first experiment to test the idea of global warming.

NASA's HyspIRI sees the forest for the trees and more
To Robert Green, light contains more than meets the eye: it contains fingerprints of materials that can be detected by sensors that capture the unique set of reflected wavelengths. Scientists have used the technique, called imaging spectroscopy, to learn about water on the moon, minerals on Mars and the composition of exoplanets. Green's favorite place to apply the technique, however, is right here on the chemically rich Earth, which is just what he and colleagues achieved this spring during NASA's Hyperspectral Infrared Imager (HyspIRI) airborne campaign.

Coal and gas are far more harmful than nuclear power
Human-caused climate change and air pollution remain major global-scale problems and are both due mostly to fossil fuel burning. Mitigation efforts for both of these problems should be undertaken concurrently in order to maximize effectiveness.

Sea ice max continues downward trend
In September 2012, the ice cap over the Arctic Ocean shrank to its lowest extent on record, about half the size of the average summertime extent from 1979 to 2000. That sea ice minimum continued a long-term trend of diminishing ice cover over the past few decades.
