Global warming could speed up honeybee decline

Study tracks spread of invasive parasite

Staff Report

FRISCO —Global warming is very likely speeding up the spread of an invasive parasite that threatens honeybees in the UK, according to scientists with Queen’s University Belfast.

After studying the gut parasite Nosema ceranae, the scientists said its numbers could increase with climate change because its better able to adapt to warmer temperatures.

The parasite is native to Asia but has spread worldwide and is likely to cause increasing damage to bees as the Earth heats up. The findings were published this week in the journal Proceedings of the Royal Society B.

“This emerging parasite is more susceptible to cold than its original close relative, possibly reflecting its presumed origin in east Asia,” said Queen’s School of Biological Sciences Professor Robert Paxton. “In the face of rising global temperatures, our findings suggest that it will increase in prevalence and potentially lead to increased honey bee colony losses in Britain.” Continue reading

Study says extreme weather doesn’t sway public opinion on global warming

Extreme weather events don’t seem to affect people’s beliefs on global warming, new research shows.

Ideology trumps science

Staff Report

FRISCO — A string of extreme global weather events between 2010 and 2012 didn’t do much to change public opinion about global warming, according to a new study by Michigan State University researchers.

They started their research with polling data collected in March 2012, after by far the warmest U.S. winter in recent memory. But most people surveyed didn’t link the unusually warm weather with global warming. In fact, only 35 percent of U.S. citizens thought that global warming caused the warm winter, according to the paper published this week in Nature Climate Change. Continue reading

Watching winter …

FRISCO — Sure, we all love snow, but I say ice is underrated. There’s such beauty in watching winter take hold across streams, lakes, reservoirs and ponds. Later in the winter it will all be covered with snow, so now’s the time to venture out to the edge of the water and watch the weird and wonderful development of the mountain cryosphere. At times, you can hear the ice sing and ping as it stretches, cracks and grows. In other places, where shards of ice are blown by the wind, it can sound like thousands of little ringing bells.

FRISCO — U.S. airlines aren’t making much progress in reducing greenhouse gas emissions, according to a new report from the International Council on Clean Transportation. Despite some improvement by individual airlines, the analysis showed there was  no net improvement in the fuel efficiency of U.S. domestic operations from 2012 to 2013.

The nonprofit organization also calculated that two of the most fuel efficient carriers  — Alaska and Spirit — had the highest operating profit margins in 2013. Meanwhile less-efficient carriers like Allegiant made profits while using old, polluting and less efficient aircraft. The study findings contradict airline industry arguments that fuel costs automatically push airlines to maximize efficiency. Continue reading

Tracking ancient greenhouse gas pulses shows climate trouble ahead

Massive permafrost meltdown could lead to runaway warming.

Carbon cycle subject to major changes as permafrost melts

Staff Report

FRISCO — There’s yet more evidence that melting Arctic permafrost will amplify global warming by releasing huge amounts of heat-trapping greenhouse gases.

In the latest study, Scientists with the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research tracked a pulse of CO2 and other greenhouse gases released to the atmosphere about 14,600 years ago. Continue reading

Climate: Researchers track disruptive Arctic rain events

Warm spells affect permafrost and wildlife

FRISCO — A closely studied 2012 rain-on-snow event in Svalbard, Norway gave researchers a chance to take a close look at how global warming may play out on the fringes of the Arctic, where humans eke out a delicate existence in balance with the elements.

The extreme weather event in January brought record warmth to the cluster of islands inside the Arctic Circle, with high temperatures climbing well above freezing at a time of year when average readings are well below freezing. Continue reading

Climate activists pushing EPA to adopt strict methane standards

Staff Report

FRISCO — Existing, low-cost technology, along with better maintenance and best management practices could easily cut U.S. methane emissions from fossil fuel operations in half, climate activists said this week, advocating for the adoption of methane standards.

The path toward those reductions is outlined by climate advocates in a new report that also shows that such standards would help improve air quality in other ways. Continue reading
