Study shows increase of CO2 in the atmosphere is lower than predicted because of plants
Plants Save the Earth from an Icy Doom (w/ Podcast)
(PhysOrg.com) -- Fifty million years ago, the North and South Poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. ...
Climate control in termite mounds
When they make their way into homes, some species of termites can be destructive pests. Their fungus-harvesting relatives in Africa and Asia, however, are known for their construction prowess, collectively ...
Climate change caused by ocean, not just atmosphere, study finds
Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.
A glucose meter of a different color provides continuous monitoring
(Phys.org) —University of Illinois engineers are bringing a touch of color to glucose monitoring.
Earth's breathable atmosphere a result of continents taking control of the carbon cycle
Scientists investigating one of the greatest riddles of the Earth's past may have discovered a mechanism to help determine how oxygen levels in the atmosphere expanded to allow life to evolve.
Progress on detecting glucose levels in saliva
Researchers from Brown University have developed a new biochip sensor that can selectively measure concentrations of glucose in a complex solution similar to human saliva. The advance is an important step ...
Microbe's innovation brought doom to Earth
The physical environment can produce sudden shocks to the life of our planet through impacting space rocks, erupting volcanoes and other events.
Ancient forests stabilized Earth's CO2 and climate
UK researchers have identified a biological mechanism that could explain how the Earth's atmospheric carbon dioxide and climate were stabilised over the past 24 million years. When CO2 levels became too low fo ...
Without plants, Earth would cook under billions of tons of additional carbon
(Phys.org) —Enhanced growth of Earth's leafy greens during the 20th century has significantly slowed the planet's transition to being red-hot, according to the first study to specify the extent to which ...
Planting a new perspective on climate research
(Phys.org) —A study on the mechanisms of how plants respond and adapt to elevated levels of carbon dioxide (CO2) and higher temperatures has opened a new perspective in climate research. Lead researcher ...
Ice-free Arctic winters could explain amplified warming during Pliocene
Year-round ice-free conditions across the surface of the Arctic Ocean could explain why the Earth was substantially warmer during the Pliocene Epoch than it is today, despite similar concentrations of carbon dioxide in the ...
High CO2 spurs wetlands to absorb more carbon
(Phys.org) —Under elevated carbon dioxide levels, wetland plants can absorb up to 32 percent more carbon than they do at current levels, according to a 19-year study published in Global Change Biology from t ...
Trees using water more efficiently as atmospheric carbon dioxide rises
A study by scientists with the U.S. Forest Service, Harvard University and partners suggests that trees are responding to higher atmospheric carbon dioxide levels by becoming more efficient at using water.
