Extraordinarily rare springs high above the rest of the world in the Arctic could serve as Earth's own little version of Europa, helping scientists picture what life might face on the mysterious Jovian moon. Europa is covered with sulfur-rich materials concentrated along cracks and ridges on its icy surface, which could hold the only clues we currently have about the composition of its hidden underground ocean. These compounds in the ice might even contain organic material that migrated...

Some regions of the deep ocean floor support abundant populations of organisms, despite being overlain by water that contains very little oxygen, according to an international study led by scientists at the United Kingdom's National Oceanography Center, Southampton. But global warming is likely to exacerbate oxygen depletion and thereby reduce biodiversity in these regions, they warn. The sunlit surface waters tend to be well oxygenated as a result of their connection with the atmosphere....

Ecologists outline necessary actions for mitigating and adapting to a changing climate Global warming may impair the ability of ecosystems to perform vital services -- such as providing food, clean water and carbon sequestration -- says the nation's largest organization of ecological scientists. In a statement released today, the Ecological Society of America (ESA) outlines strategies that focus on restoring and maintaining natural ecosystem functions to mitigate and adapt to climate change....

Weizmann Institute scientists show that in one kind of forest, its 'energy budget' includes significant reserves of heat The simple formula we've learned in recent years "“ forests remove the greenhouse gas CO2 from the atmosphere; therefore forests prevent global warming "“ may not be quite as simple as we thought. Forests can directly absorb and retain heat, and, in at least one type of forest, these effects may be strong enough to cancel out a good part of the benefit in...

Economists, assigning values to 'ecosystem services,' report staggering totals and rates of return on investment Experts concluding the global DIVERSITAS biodiversity conference today in Cape Town described preliminary research revealing jaw-dropping dollar values of the "ecosystem services" of biomes like forests and coral reefs "“ including food, pollution treatment and climate regulation. Undertaken to help societies make better-informed choices, the economic research shows a single...

Sustainable water use, climate change impacts on international markets, restoration of Chicago ecosystems among research projects How do humans and their environment interact, and how can we use knowledge of these links to adapt to a planet undergoing radical climate and other environmental changes? To answer these and related questions, the National Science Foundation (NSF) has awarded 14 grants to scientists, engineers and educators across the country to study coupled natural and human...

Humanity needs to act now to avoid threats to human well-being caused by irreversible damage to the Earth, its climate, species and life-supporting systems. Scientists say it has become essential to define what levels of such human-caused change are "Ëœsafe' and which are "Ëœunsafe', and to stay within these boundaries. The call comes from 28 of the world's most eminent environmental scientists, published today in the world's leading science journal, Nature. The...

Geoengineering techniques aim to slow global warming through the use of human-made changes to the Earth's land, seas or atmosphere. But new research shows that the use of geoengineering to do environmental good may cause other environmental harm. In a symposium at the Ecological Society of America's Annual Meeting, ecologists discuss the viability of geoengineering, concluding that it is potentially dangerous at the global scale, where the risks outweigh the benefits."The bigger the scale of...

While policymakers across of the globe are relying on environmental restoration projects to fuel emerging market-based environmental programs, an article in the July 31 edition of Science by two noted ecologists warns that these programs still lack the scientific certainty needed to ensure that restoration projects deliver the environmental improvements being marketed.Markets identify the benefits humans derive from ecosystems, called ecosystem services, and associate them with economic...

A rare April freeze in 2007 provided researchers at the Department of Energy's Oak Ridge National Laboratory with further evidence that climate change could have negative effects on stream and forest ecosystems.As warm weather arrives sooner in many parts of the nation, forest plants and trees on the banks flourish, shading the stream from sunlight and causing an overall decrease in productivity in the late spring and summer. A research paper published in this month's issue of Global Change...

Environmental science is a science that contains a wide range of scientific disciplines. These disciplines are grouped together based on the natural environment which they encompass and interact with. These sciences include physical, chemical, and biological components. Environmental science provides an interdisciplinary approach to the study of the environmental systems. The most common way environmental science is studied is through the work of one individual or small team drawing on the...
