The Arctic is rapidly warming, with stronger effects than observed elsewhere in the world. The Arctic regions are particularly important with respect to climate change, as permafrost soils store huge amounts of the Earth’s soil carbon (C). Warming of Arctic soils and thawing of permafrost can have substantial consequences for the global climate, as the large C stored in soils could be released to the atmosphere as the greenhouse gases carbon dioxide (CO2) and methane (CH4). The release of these heat-trapping gases, in turn, has the potential to further enhance climate warming.

A recent Finnish study conducted at the University of Jyväskylä showed that adolescents with better aerobic fitness have more compliant arteries than their lower fit peers do. The study also suggests that a higher anaerobic threshold is linked to better arterial health. The results were published in the European Journal of Applied Physiology.

Wild lands are practically worthless.

They’re not worthless to the things that live in them, of course. They love ‘em. And they aren’t worthless aesthetically, if that’s your bag. Any place with plants slurps up carbon dioxide, providing a bulwark against climate change. And they probably have value as a matter of public health; some research suggests that trees cut down pollutants in cities, and that exposure to nature extends lifespan—or, really, lack of trees reduces lifespan—though nobody’s really sure how.
