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. This could adversely hit the availability of water for irrigation and power projects including the Bhakra dam.

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.

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 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. 

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. 

A new study has suggested that the government must consider changes occurring due to climate change while planning new hydropower projects.

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.

The gradual change in temperature and rainfall patterns in Darjeeling hills is beginning to affect the production of the famous Darjeeling tea.

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.
