Want to 'see' climate change? Check your thermometer
Scientists often use satellites, supercomputers or high-tech arrays of instruments to show how the climate is changing.
A simpler way to estimate the feedback between permafrost carbon and climate
One of the big unknowns in predicting climate change is the billions of tons of carbon frozen in Arctic permafrost. As global warming causes soil temperatures to increase, some of this carbon will decompose and enter the ...
Are we wiser about tsunamis? Expert says yes and no
The world may not be well prepared for the next significant tsunami, reports Northwestern University tsunami expert Emile A. Okal in a new study that includes a "wisdom index" for 17 tsunamis since 2004.
Researchers hone technique for finding signs of life on Mars
For centuries, people have imagined the possibility of life on Mars. But long-held dreams that Martians could be invaders of Earth, or little green men, or civilized superbeings, all have been undercut by missions to our ...
Cost of cloud brightening for cooler planet revealed
University of Manchester scientists have identified the most energy-efficient way to make clouds more reflective to the sun in a bid to combat climate change.
Adjusting Earth's thermostat, with caution
A vast majority of scientists believe that the Earth is warming at an unprecedented rate and that human activity is almost certainly the dominant cause. But on the topics of response and mitigation, there is far less consensus.
Meteorites expose Moon surface formation
Lunar meteorites contradict a theory of how the Moon's crust formed, originally based on Apollo mission samples.
Atmospheric particles can brighten cold clouds as well as warm ones
For the first time, modeling research led by Pacific Northwest National Laboratory found that atmospheric particles can brighten cold clouds in the Arctic. Using simulations, they showed that low clouds over the Arctic may ...
Making clean drinking water universally available is 'achievable'
(Phys.org) —Making clean drinking water globally accessible is one of the biggest challenges of this century. Yet a new study by Oxford University contends that this goal is achievable if the key elements of good governance ...
New research to support the huge potential of tidal power
(Phys.org)—New research from a global group of scientists and engineers, including from the University of Southampton, has been published in a special issue journal of the Royal Society. The work is in support of tidal ...
