On Mars or Earth, biohybrid can turn carbon dioxide into new products

Chemists have created a hybrid system of bacteria and nanowires that captures energy from sunlight and transfers it to the bacteria to turn carbon dioxide and water into organic molecules and oxygen. On Earth, such a biohybrid could remove carbon dioxide from the atmosphere. On Mars, it would provide colonists with raw material to manufacture organic compounds ranging from fuels to drugs. The efficiency is greater than the photosynthetic efficiency of most plants.

If a warm U.S. winter was ‘a preview of global warming,’ what part did a polar vortex play? – Getaka.co.in

The winter that just ended was the sixth-warmest on record in the contiguous United States, according to the National Oceanic and Atmospheric Administration. And one feature of that winter was a strong zonal, west-to-east flowing polar vortex. Wait, what? Usually…

How stable is deep ocean circulation in warmer climate?

If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a new study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.

How stable is deep ocean circulation in warmer climate?

(Rutgers University) If circulation of deep waters in the Atlantic stops or slows due to climate change, it could cause cooling in northern North America and Europe – a scenario that has occurred during past cold glacial periods. Now, a Rutgers coauthored study suggests that short-term disruptions of deep ocean circulation occurred during warm interglacial periods in the last 450,000 years, and may happen again.

International ozone treaty stops changes in Southern Hemisphere winds

(University of Colorado at Boulder) The Montreal Protocol of 1987 phased out production of ozone-destroying substances such as chlorofluorocarbons (CFCs). Beginning around 2000, concentrations of those chemicals in the stratosphere started to decline and the ozone hole began to recover. In this study, researchers have shown that around the year 2000, the circulation of the Southern Hemisphere also stopped expanding polewards — a pause or slight reversal of the earlier trends.

Simple framework helps future ocean studies

(King Abdullah University of Science & Technology (KAUST)) A framework that helps marine scientists select localized carbon dioxide levels for experiments aims to improve robustness in global warming studies.

Observing phytoplankton via satellite

Thanks to a new algorithm, researchers can now use satellite data to determine in which parts of the ocean certain types of phytoplankton are dominant. In addition, they can identify toxic algal blooms and assess the effects of global warming on marine plankton, allowing them to draw conclusions regarding water quality and the ramifications for the fishing industry.
