Greenland melting likely increased by bacteria in sediment

Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island’s contribution to sea-level rise, according to scientists. That’s because the microbes cause sunlight-absorbing sediment to clump together and accumulate in the meltwater streams, according to new study. The findings can be incorporated in climate models, leading to more accurate predictions of melting, scientists say.

Groupthink, Pal Review And The Climate Fraud

A little over two decades ago, Dr. Irving Janis, professor of psychology at Yale University, published Groupthink in which he explained how a group of like-minded people could share a common belief or goal whilst completely ignoring any evidence that…

Climate Models Wrong Again: Drylands Are Not Getting Drier

Scientists have thought that global warming will increase the availability of surface water—freshwater resources generated by precipitation minus evapotranspiration—in wet regions, and decrease water availability in dry regions [drylands]. This expectation is based primarily on atmospheric thermodynamic processes. As air…

Surprising news: Drylands are not getting drier

A new study shows the importance of long-term soil moisture changes and associated soil moisture-atmosphere feedbacks in future predictions of water availability in drylands. The researchers identified a long-term soil moisture regulation of atmospheric circulation and moisture transport that largely ameliorates the potential decline of future water availability in drylands, beyond that expected in the absence of soil moisture feedbacks.

Mouse-controlled mouse helps researchers understand intentional control

Researchers have devised a brain machine interface (BMI) that allows mice to learn to guide a cursor using only their brain activity. By monitoring this mouse-controlled mouse moving to a target location to receive a reward, the researchers were able to study how the brain represents intentional control.

Land ecosystems are becoming less efficient at absorbing CO2

Land ecosystems currently play a key role in mitigating climate change. The more carbon dioxide (CO2) plants and trees absorb during photosynthesis, the process they use to make food, the less CO2 remains trapped in the atmosphere where it can cause temperatures to rise. But scientists have identified an unsettling trend – as levels of CO2 in the atmosphere increase, 86 percent of land ecosystems globally are becoming progressively less efficient at absorbing it.
