Analysis of the Last Glacial Maximum sheds light on climate models’ ability to simulate tropical climate change
How will rainfall patterns across the tropical Indian and Pacific regions change in a future warming world? Climate models generally suggest that the tropics as a whole will get wetter, but the models don’t always agree on where rainfall patterns will shift in particular regions within the tropics.
A new study, published online May 19 in the journal Nature Geoscience, looks to the past to learn about the future of tropical climate change, and our ability to simulate it with numerical models. (more…)
*University of Minnesota research suggests that wastewater treated with standard technologies contains far greater quantities*
MINNEAPOLIS / ST. PAUL — A new University of Minnesota study reveals that the release of treated municipal wastewater – even wastewater treated by the highest-quality treatment technology – can have a significant effect on the quantities of antibiotic-resistant bacteria, often referred to as “superbacteria,” in surface waters.
The study also suggests that wastewater treated using standard technologies probably contains far greater quantities of antibiotic-resistant genes, but this likely goes unnoticed because background levels of bacteria are normally much higher than in the water studied in this research. (more…)
