Climate change affects glacier health
A study suggests chances of half of the glaciers in Satluj basin disappearing by 2050.

Changing climatic patterns are affecting the health of glaciers in the Himalayan region. A new study has warned that as many as 55 percent of glaciers in the Satluj basin may disappear by 2050 and 97 percent by 2090 under extreme climate change scenario.

Seismic activity triggered by human actions like the construction of large reservoirs or injection of wastewater into the ground for oil and gas production can have far greater implications than previously thought, a new study has revealed.

Groundwater decline increases carbon emission
The latest study shows declining reserves and rising carbon dioxide emissions from pumping groundwater add to India’s environmental woes.

Over-extraction of groundwater is a major environmental challenge in many parts of India. It is not only leading to a rapid decline in groundwater reserves but also contributing to India’s carbon emissions, a new study has warned.

Scientists are literally looking into the ground for clinching evidence of climate change. A new study of geothermal records across India has shown that the country has experienced about one degree of warming over the baseline mean temperature of the 19th century.

Wind turbines impact Western Ghats ecology
Wind farms reduce the number of predatory birds which in turn results in an increase in the density of vertebrates like lizards in Western Ghats.

Wind energy, considered a clean source of energy, does have a carbon footprint and is also known to disturb bird life. Now a new study done in the Western Ghats has found that wind farms in biodiversity-rich areas can have deeper ecological consequences beyond already known impacts.

Global warming impacts on India to be huge
The latest report from the UN's climate change panel says that world is already witnessing the consequences of one-degree global warming.

The latest report of the UN’s Intergovernmental Panel on Climate Change (IPCC), formally released on Monday, warns that global warming is occurring faster than anticipated and that it can have devastating impacts if steps are not taken to cut down emissions.

Climate change affects hydropower generation
A study reveals that hydropower generation from top seven hydropower projects has suffered due to climate variability in the past six decades.

Solar water purifier with a difference
With no electricity required and no wastewater, the new purifier works even under cloudy conditions and diffused solar radiation.

The availability of potable drinking water remains a challenge in rural areas in several parts of the country. Commercially available water filters are costly, need electricity to run and reverse osmosis (RO)-based purifiers waste a lot of water.

Emission inventory for Delhi
Scientists and students come together to map air pollution sources in the capital.

A group of scientists and students are braving the heat and dust this summer in the national capital to map all possible sources of air pollution, so that by winter this year, we can get a fair idea of different sources of pollution in the city.
