How will global warming affect wood frogs?

Study documents nuanced response Staff Report A far-ranging study of wood frogs have found that the bog-breeding amphibians could be vulnerable to global warming at the southern edge of their range, and that the population could shift northward, similar to many other species. But the research, covering more than 740 wood frog populations in 27 … Continue reading How will global warming affect wood frogs?

We’re losing the global warming poker game

Greenhouse gases tilt odds toward record warmth Staff Report It’s highly unlikely Earth would have seen a three-year run of record global temperatures without its blanket of human-caused greenhouse gases, scientists concluded in a new study that tried to pin down the relationship between record warmth and human-caused global warming. Without the warming effect of … Continue reading We’re losing the global warming poker game

Global warming intensified Colorado’s deadly 2013 floods

Detailed modeling helps project how climate change will alter extreme weather Staff Report Global warming likely boosted rainfall during Colorado’s deadly 2013 floods by 30 percent, according to new research. The September storms killed nine people and destroyed or damaged about 900 homes. Altogether, some spots saw more than 17 inches of rain, sending the … Continue reading Global warming intensified Colorado’s deadly 2013 floods

Is global warming changing the Southwest monsoon?

Study shows more intense but less frequent storms An international research team says monsoon storms in the Southwest have become less frequent but more intense, bringing more extreme wind and rain to central and southwestern Arizona than just a few decades ago. The study, led by scientists with the University of Arizona, compared precipitation records … Continue reading Is global warming changing the Southwest monsoon?

Global warming will devastate marginal farming areas

Southwest will be hit especially hard Staff Report Most agriculture in the southwestern U.S. is already marginal, possible only because U.S. taxpayers support cheap water for questionable crops. And because of global warming, the outlook is grim as the region continues to warm and dry. By 2050, Arizona cotton production will drop to less than … Continue reading Global warming will devastate marginal farming areas

Increased greening amplifies global warming in boreal zones

New research focuses on biophysical impacts of climate change Staff Report Vegetation plays a key role in the climate change equation, with a recent study showing that vegetation density has substantial climate impacts. According to the research by the European Union’s Joint Research Center, the findings show that vegetation has a warming effect in cold … Continue reading Increased greening amplifies global warming in boreal zones

Global warming puts sea turtles at risk

As temps warm, most eggs will produce females Staff Report Global warming was first identified as a potential threat to sea turtles in the 1980s because the temperature at which the eggs incubate helps determine the sex of the embryos. A new study now adds weight to those concerns, finding that  warmer temperatures could lead … Continue reading Global warming puts sea turtles at risk

Marine preserves can protect oceans from global warming

Major study shows need for expansion of protected areas Staff Report As much as a third of the world’s oceans should be protected to help buffer against long-term climate change impacts, scientists said in a new study, calling for an expansion of protected areas, as well as better management. Globally, coastal nations have committed to … Continue reading Marine preserves can protect oceans from global warming

Global warming means major changes for U.S. fisheries

Warming ocean will drive many commercially important species to new habitats; detailed projections can help  coastal communities adapt Staff Report Climate change isn’t just heating the surface of the Earth. It’s also warming deep ocean water, and along the coast of the northeastern U.S. bottom-water temperatures are expected to increase by 6.6 to 9 degrees … Continue reading Global warming means major changes for U.S. fisheries
