The winter of 2011–12 was the second in a row to feature La Niña, the quasi-cyclic cooling of the eastern tropical Pacific—but the two seasons departed from the La Niña script in strikingly different ways.
As I write this, the Boulder winds sound indistinguishable from a car driving by our house. But it is another sound—the sound of ice—that is the inspiration for this blogpost. The ice on ponds and lakes.
Paradata—information on how people access and share information through social media—could play a big role in assessing the usefulness of educational resources in the university setting, according to Susan Van Gundy.
Atmospheric carbon dioxide has been increasing fairly steadily for decades, but methane has accumulated at a more erratic pace. The increase virtually stalled for much of the last decade before resuming after 2007.
If you’re an American, it’s tough to avoid corn. This ubiquitous starch turns up in soft drinks, compostable cups, and automobile fuel—and even plays a role in U.S. heat waves, including the intense one of 2011.
Hazy skies and fiery sunsets were noted across much of the central United States after the huge Wallow Fire developed in Arizona. But there’s also a quantitative way to track fire’s impact on the surrounding air.
The Sun drives our climate, so a slowdown in solar activity would surely put the brakes on global warming—wouldn’t it? That question percolated through the media following a set of reports from a solar physics meeting.
An email exchange following Part I revealed the enthusiasm of the Boulder weather community for clouds and the presence of many instruments probing the atmosphere over Boulder—and, in the end, the height of the formation.
