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

Climate: October ends up as warmest on record

2014 on track to be warmest year ever


Widespread warmth prevailed globally in October 2014.

Staff Report

FRISCO — October 2014 will go into the record books as the warmest on record for Earth, and it’s very likely that the year as a whole will end up record warm, according to climate experts with the National Climatic Data Center releasing their monthly state of the climate analysis.

For October, the average global temperature (land and sea surface combined) was 1.33 degrees Fahrenheit above average, and for the year to-date, the average global temperature is 1.22 degrees Fahrenheit above average, also a record for the 10-month January to October span. Continue reading

Climate: Closing the emissions gap

Carbon neutral by 2050?


Can the globe be carbon-neutral by 2050?

Staff Report

FRISCO — Limiting global warming to two degrees Celsius will require reaching carbon neutrality by mid-century, UN officials said this week as they released a new emissions gap report that clearly outlines the global carbon budget.

“Don’t believe it if you hear politicians saying it can’t be done. It can,” said Achim Steiner, director of the UN Environmental Program. Steiner and other top officials said increased energy efficiency and smart growth are the keys to reaching global climate targets.

“If this was prohibitively costly we’d have to make some calculations, but it’s not,” Steiner said, explaining that switching to a low carbon economy offers opportunity for expanded economic development and a path toward minimizing future climate change impacts. Continue reading

Climate: New book details global glacier losses

Most of the world’s ice rivers are shrinking into oblivion

FRISCO — For mountain dwellers around the world, shrinking glaciers are one of the most vivid symptoms of Earth’s rising fever. Those gleaming mantles of ice have already disappeared from iconic landscapes like Glacier National Park.

Globally, millions of people rely on glacier-regulated stream flows for water supplies, so communities need to prepare for disruptions in the hydrological cycle because it’s becoming increasingly apparent that the meltdown is not going to stop. Continue reading

Do small volcanoes have a big climate impact?

New research tracks aerosols from volcanic eruptions

Staff Report

FRISCO — Sunlight-reflecting particles from relatively small volcanic eruptions may add up to have a significant effect on global temperatures, according to a new climate study that tries to quantify the cumulative impact of aerosols from volcanoes.

According to the research, based on a combination of measurements taken on the ground, in the air and from satellites, small volcanic eruptions that occurred between 2000 and 2013 deflected almost double the amount of solar radiation previously estimated.

That’s enough to lower global temperatures by about  0.05 to 0.12 degrees Celsius, the scientists concluded in their study, which appears in Geophysical Research Letters. Continue reading

New NASA visual helps trace path of greenhouse gases

Staff Report

FRISCO — In a way, addressing global warming is like fighting a ghost. How do you tackle odorless and colorless heat-trapping gases like carbon dioxide and methane?

NASA, the government agency that literally has the best global perspective on climate change, has just released a new computer generated animation that help show the source of greenhouse gases and how they disperse around the planet. Continue reading

Study show drop in Beaufort Sea polar bear numbers



Is dwindling sea ice a factor?

Staff report

FRISCO — Polar bear populations in the southern Beaufort Sea  dropped 40 percent between 2000 and 2010, biologists say in a new study. The research suggests that survival of adult bears and cubs was especially low from 2004 to 2006, when most of the decline occurred.

“Of the 80 cubs observed in Alaska from 2004 to 2007, only 2 are known to have survived,” said Jeff Bromaghin, a U.S. Geological Survey research statistician and lead author of the study. Continue reading
