You are what you eat, as the saying goes, and while good dietary choices boost your own health, they also could improve the health care system and even benefit the planet. Healthier people mean not only less disease but also reduced greenhouse gas emissions from health care. As it turns out, some relatively small diet tweaks could add up to significant inroads in addressing climate change.
Terms such as no-fat or no-sugar, low-fat or reduced-salt on food packaging may give consumers a sense of confidence before they purchase, but these claims rarely reflect the actual nutritional quality of the food, according to a new study led by researchers at the University of North Carolina at Chapel Hill.
Once a tropical storm, now a sub-tropical storm, the remnants of the tropical low pressure area formerly known as 11S was spotted by NASA's Aqua satellite, still spinning in the Southern Indian Ocean.
On March 14 at 2230 UTC (6:30 p.m. EST) the remnants of Tropical Cyclone 11S were located near 29.8 degrees south latitude and 52.4 degrees east longitude, about 530 nautical miles south-southwest of La Reunion Island.
Orthodox economic measures like Gross Domestic product fail to measure the things that matter most, write Judith Schleicher & Bhaskar Vira: like human wellbeing and ecological health. This creates a systematic bias in 'development' policies that must urgently be addressed if we are to build an inclusive, equitable and sustainable society
Without nature, humans could be neither healthy nor happy.
Polar cod fulfil a key role in the Arctic food web, as they are a major source of food for seals, whales and seabirds alike. But the polar cod themselves might soon be the hungry ones. Under the ice of the central Arctic, the juvenile fish are indirectly but heavily dependent on ice algae. As a result, retreating sea ice could have far-reaching impacts on the food web. Though researchers have long since suspected this relation existed, an international team of researchers led by the Alfred Wegener Institute (AWI), Helmholtz Centre for Polar and Marine Research, have now successfully confirmed it.
We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of the mechanisms by which a colder climate was accompanied by depleted atmospheric CO2 during past ice ages.
The overall goal of the work is to better understand how and why the earth goes through periodic climate change, which could shed light on how man-made factors could affect the global climate.
