Video: Developing carbon management solutions
Jul 20, 2017
Global consumption of fossil fuels is causing atmospheric carbon dioxide and other greenhouse gases to rise to levels that threaten human and environmental sustainability. These gases warm the planet and negatively impact ...
Proposed benefits of rising carbon dioxide are more likely driven by water
Jul 10, 2017
One of the expected benefits from rising atmospheric carbon dioxide is that plants may use less water and avoid some of the damaging effects of drought. The basis for this effect is that plants close the pores called stomata ...

Jul 07, 2017
Throughout the last 800,000 years, Antarctic temperatures and atmospheric carbon dioxide concentrations have showed a similar evolution. However, they were different during the transition to the last ice age—approximately ...
Researchers advocate statistical approach to search for Earth-like planets
Jun 14, 2017
A team of astronomers at the University of Chicago and Grinnell College seeks to change the way scientists approach the search for Earth-like planets orbiting stars other than the sun. They favor taking a statistical comparative ...
The three-minute story of 800,000 years of climate change with a sting in the tail
Jun 13, 2017
There are those who say the climate has always changed, and that carbon dioxide levels have always fluctuated. That's true. But it's also true that since the industrial revolution, CO₂ levels in the atmosphere have climbed ...
Team takes temperature to determine cause of Ice Age
Jun 13, 2017
New research by Simon Fraser University professor Karen Kohfeld and University of Tasmania professor Zanna Chase, published in the journal Earth and Planetary Science Letters, examines how the ocean pulled carbon dioxide ...
Teaming nature and technology for climate solutions
Jun 08, 2017
One corner of the Omani desert is blanketed by a type of rock with an unquenchable thirst for a colorless and odorless gas vital to life on Earth. That gas is CO2, and when it reacts with peridotite, a rock abundant in the ...
Bacteria may supercharge the future of wastewater treatment
May 31, 2017
Wastewater treatment plants have a PR problem: People don't like to think about what happens to the waste they flush down their toilets. But for many engineers and microbiologists, these plants are a hotbed of scientific ...
Volcanic 'geoengineering' may have caused a climate catastrophe that killed most animal species
