Seawater intrusion (SI) is a global issue, exacerbated by increasing demands for freshwater in coastal zones and predisposed to the influences of rising sea levels and changing climates. This review presents the state of knowledge in SI research, compares classes of methods for assessing and managing SI, and suggests areas for future research. We subdivide SI research into categories relating to ... read more >>
When you think about NASA, water probably isn't the first thing that comes to mind. But NASA knows that access to fresh water and the impacts of climate change will be two of this century's biggest challenges. Their ongoing AirSWOT mission — a partnership with the French and Canadian space agencies — will help to improve our understanding in both of those areas.
AirSWOT is actually part of a br ... read more >>
It is often said of the Arctic that, when it comes to climate change, this region of Earth is the proverbial 'Canary in the Coalmine' - that is, if anywhere is going to alert us that something's up, it's up there in the far north. So we have seen sea-ice coverage diminishing dramatically and sea-ice volume falling off a cliff. Land-ice too is on the retreat: a mineral exploration company that has ... read more >>
This brand-new household environmental calculator is the first of its kind — it shows not only the carbon but also energy, water, wastewater, trash, and stormwater runoff footprints of your home and lifestyle.

The Impact ... read more >>
A type of volcanic rock may be the key to long-term carbon sequestration, research shows, as the surface of such rock reacts with carbon dioxide to form a mineral. Storing the CO2 in reactive mafic rock formations deep underground means "you are making rocks out of [the CO2]. It’s not sitting there as a high-pressure fluid" posing a potential earthquake threat, said David Bercovici, a professor o ... read more >>
As Congress and the White House explore ways to encourage Americans to conserve energy, a new study by the University of Michigan shows that the average individual energy demand for heating and cooling has decreased over the past 50 years. ... read more >>
Structural problems on the roof of Joao Havelange Stadium in Rio de Janeiro have prompted officials to close the arena until the issues have been addressed. The metallic roof weighs more than 3,600 tons and is "supported by four complex supporting white steel arches -- designed in a rhythmic repetition of irregular forms -- and cable-stayed strings" that make the roof appear "to hang in mid-air." ... read more >>
