Ocean activity controls summer monsoons

Results may help researchers interpret ancient monsoon variations, predict future activity in the face of climate change. Each summer, a climatic shift brings persistent wind and rain to much of Southeast Asia, in the form of a seasonal monsoon. The general cause of the monsoon is understood to be an increasing temperature difference between the…

Rice husks can remove microcystin toxins from water

Scientists at The University of Toledo have discovered that rice husks can effectively remove microcystin from water, a finding that could have far-reaching implications for communities along the Great Lakes and across the developing world. An abundant and inexpensive agricultural byproduct, rice husks have been investigated as a water purification solution in the past. However,…

Fracking: Earthquakes are triggered well beyond fluid injection zones

Using data from field experiments and modeling of ground faults, researchers at Tufts University have discovered that the practice of subsurface fluid injection used in ‘fracking’ and wastewater disposal for oil and gas exploration could cause significant, rapidly spreading earthquake activity beyond the fluid diffusion zone. Deep fluid injections — greater than one kilometer deep…

Climate extremes explain 18%-43% of global crop yield variations

Overall, year-to-year changes in climate factors during the growing season of maize, rice, soy and spring wheat accounted for 20%-49% of yield fluctuations, according to research published in Environmental Research Letters. Climate extremes, such as hot and cold temperature extremes, drought and heavy precipitation, by themselves accounted for 18%-43% of these interannual variations in crop…

Better Soil, Farms and a Climate Change Solution

Gabe Brown has super healthy soil on his farm and his farm is more productive. Tests show soil on Brown’s farm had 7 times as much nitrogen, 5 times as much phosphorus, 8 times as much potassium, and 4 times as much organic carbon and organic matter percent as the nearby farms. His soil infiltrates 30…

Does bio-fertilizer help the soil?

Miranda Hart, who teaches biology at UBC’s Okanagan campus, says despite a decades-long practice, there could be environmental consequences of adding bio-fertilizers into soil. It’s common practice for farmers to use bio-fertilizers as a method to improve crop production. These added microorganisms will live in the soil, creating a natural and healthy growing environment. However,…

75% of US Southeast Atlantic coast facing sea-level rise in the next 10 years

New research shows 75 percent of the Atlantic Coast from North Carolina to Central Florida will be highly vulnerable to erosion and inundation from rising tides by 2030, negatively impacting many coastal species’ nesting habitats. The new data reflect a 30 percent increase in highly vulnearable areas in the region since 2000, the date of…

Consequences of ocean acidification 

Ocean acidification could have serious consequences for the millions of people globally whose lives depend on coastal protection, fisheries and aquaculture, a new publication suggests. Writing in Emerging Topics in Life Sciences, scientists say that only significant cuts in fossil fuel emissions will prevent the changes already evident in areas with projected future carbon dioxide…

Another breeding failure emperor penguin colony

Emperor penguins at the Halley Bay colony in the Weddell Sea have failed to raise chicks for the last three years, scientists have discovered. Researchers from British Antarctic Survey (BAS) studied very high resolution satellite imagery to reveal the unusual findings, published today (25 April 2019) in the journal Antarctic Science. Until recently, the Halley…

Soft tissue promotes coral recovery from bleaching

Climate change and ocean warming threaten coral reefs and disrupt the harmonious relationship between corals and their symbiotic algae, a process known as “coral bleaching.” However, a new study conducted by scientists at the University of Hawai’i (UH) at Mānoa and the California Academy of Sciences revealed soft tissues that cover the rocky coral skeleton…
