After two decades of hardwork, on 5 February 2012, a team of Russian scientists began drilling at Lake Vostok, the largest of more than 140 sub-glacial lakes and the most deeply buried of the lakes hidden under the Antarctic ice cap.

The writ petitions have been filed in the public interest to quash Jal Mahal Tourism Project and cancel Mansagar Lake Precinct Lease Agreements dated 22nd November, 2005 giving 100 acres of land on lease for a period of 99 years to Jal Mahal Resorts Private Limited and Jal Mahhal Leave & License Agreement dated 22nd November, 2005.

In China, and elsewhere, long-term economic development and poverty alleviation need to be balanced against the likelihood of ecological failure. Here, we show how paleoenvironmental records can provide important multidecadal perspectives on ecosystem services (ES). More than 50 different paleoenvironmental proxy records can be mapped to a wide range of ES categories and subcategories. Lake sediments are particularly suitable for reconstructing records of regulating services, such as soil stability, sediment regulation, and water purification, which are often less well monitored.

About one-fifth of organic carbon in sediments is bound to reactive iron phases, which are metastable over geological timescales and may therefore serve as a sink for the long-term storage of organic carbon.

Intense debate persists about the climatic mechanisms governing hydrologic changes in tropical and subtropical southeast Africa since the Last Glacial Maximum, about 20,000 years ago. In particular, the relative importance of atmospheric and oceanic processes is not firmly established. Southward shifts of the intertropical convergence zone (ITCZ) driven by high-latitude climate changes have been suggested as a primary forcing, whereas other studies infer a predominant influence of Indian Ocean sea surface temperatures on regional rainfall changes.

The consumption of shallow groundwater with elevated concentrations of arsenic is causing widespread disease in many parts of South and Southeast Asia. In the Bengal Basin, a growing reliance on groundwater sourced below 150-m depth—where arsenic concentrations tend to be lower—has reduced exposure. Groundwater flow simulations have suggested that these deep waters are at risk of contamination due to replenishment with high-arsenic groundwater from above, even when deep water pumping is restricted to domestic use.

Uncertainties over contaminated groundwater in southern Asia highlight gaps in science.
