A new University of Colorado Boulder-led study appears to answer contentious questions about the onset and cause of Earth’s Little Ice Age, a period of cooling temperatures that began after the Middle Ages and lasted into the late 19th century. According to the new study, the Little Ice Age began abruptly between A.D…

These researchers assert that the Arctic is already suffering some of the effects that, according to The Intergovernmental Panel on Climate Change (IPCC), correspond with a “dangerous climate change”. Currently, the rate of climatic warming exceeds the rate of natural adaptation in arctic ecosystems…

The nitrogen cycle has been profoundly altered by human activities, and that in turn is affecting human health, air and water quality, and biodiversity in the U.S., according to a multi-disciplinary team of scientists writing in the 15th publication of the Ecological Society of America’s Issues in Ecology. In “Excess Nitrogen in the U.S…

A natural substance obtained from seeds of the “miracle tree” could purify and clarify water inexpensively and sustainably in the developing world, where more than 1 billion people lack access to clean drinking water, scientists report. Research on the potential of a sustainable water-treatment process requiring only tree seeds and sand appears in ACS’ journal […]

Scientists have uncovered a lot about the Earth’s greatest extinction event that took place 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system. […]

Many of the particles in the atmosphere are produced by the natural world, and it is possible that plants have in recent decades reduced the effects of the greenhouse gases to which human activity has given rise. One consequence of this is that the climate may be more sensitive to emissions caused by human activity […]

Alberta’s oilsands have water challenges. Oilsands development uses a vast amount of water and even though it’s recycled multiple times, the recycling concentrates the toxins and metals leftover from extracting and upgrading the bitumen, resulting in tailings ponds that are both a lightening rod for controversy and a significant risk to the environment…

When a plant encounters drought, it does its best to cope with this stress by activating a set of protein molecules called receptors. These receptors, once activated, turn on processes that help the plant survive the stress…
