San Francisco State astronomer Stephen Kane and a team of researchers locate the habitable zone, the region where water could exist on the surface of a planet, on the Wolf 1061, a planetary system that's 14 light years away.
Why do some trees die in a drought and others don't? And how can we predict where trees are most likely to die in future droughts? Scientists from the University of California, Davis, and colleagues examined those questions in a study published in the journal Ecology Letters.
Researchers at the University of Minnesota have found that major flooding and large amounts of precipitation occur on 500-year cycles in central China. These findings shed light on the forecasting of future floods and improve understanding of climate change over time and the potential mechanism of strong precipitation in monsoon regions.
Sea level in the Northeast and in some other US regions will rise significantly faster than the global average, according to a report released by the National Oceanic and Atmospheric Administration. In a worst-case scenario, global sea level could rise by about 8 feet by 2100, according to the report, which lays out six scenarios intended to inform national and regional planning.
Researchers have found that while advanced wood-burning cookstoves can provide benefits to the environment and climate, these benefits are less than expected due to higher emissions measured in the field compared to laboratory settings. The study, conducted in rural Malawi, found that pollutant emissions from these stoves were much higher than was reported in laboratory testing, due in part to how the stoves were being used.
Some of the most important crops risk substantial damage from rising temperatures. To better assess how climate change caused by human greenhouse gas emissions will likely impact wheat, maize and soybean, an international team of scientists now ran an unprecedentedly comprehensive set of computer simulations of US crop yields. Importantly, the scientists find that increased irrigation can help to reduce the negative effects of global warming on crops -- but this is possible only in regions where sufficient water is available.
A new University of Washington study finds that one of Alaska's most abundant freshwater fish species is altering its breeding patterns in response to climate change, which could impact the ecology of northern lakes that already acutely feel the effects of a changing climate.
An international team discovers that production of a potent greenhouse gas can be bypassed as soil nitrogen breaks down into unreactive atmospheric N2.
University of California, Irvine glaciologists have uncovered large oceanic valleys beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved by earlier advances of ice during colder periods, the subsurface troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.
Researchers are reviving one of the Mississippi River's main filters: the floodplain. The result is a unique environment that removes nitrogen, a contributor to the Gulf of Mexico's dead zone.
