Sharks in acidic waters avoid smell of food
The increasing acidification of ocean waters caused by rising atmospheric carbon dioxide levels could rob sharks of their ability to sense the smell of food, a new study suggests.
How NASA's new Orbiting Carbon Observatory will help us understand alien worlds
On July 2, NASA successfully launched the Orbiting Carbon Observatory-2 (OCO-2), a remote sensing satellite on a mission to precisely measure carbon dioxide levels in our planet's atmosphere. As a bonus OCO-2 ...
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 ...
Scientists look beyond alarming milestone in carbon dioxide levels
The world made a down payment on decades of dangerous weather last month, reaching an average atmospheric carbon dioxide level above 400 parts per million.
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.
Next 15 years is 'crunch time' for climate change
Time is running out to employ a mitigation strategy that would avert severe global damage from climate change, a University of Illinois energy policy expert says.
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 ...
Amber provides new insights into the evolution of the Earth's atmosphere
An international team of researchers led by Ralf Tappert, University of Innsbruck, reconstructed the composition of the Earth's atmosphere of the last 220 million years by analyzing modern and fossil plant ...
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 ...
Algae fossils shed light on adaptation to global warming
When thinking about global warming, one thing usually comes to mind: man-made CO2 emissions. Industrialisation single-handedly caused the rise of Earth's surface temperature, leading to the likes of shrinking ...
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 ...
