  • 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 ...

  • 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. Billions of litres of groundwater pumped out every year contribute...

  • 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. The new study that combines data f...

  • Here is more evidence why we need to worry about climate change. A new study says extreme rainfall events are on the rise in India and attributes the trend to man-made emissions, what scientists call anthropogenic warming. Not just this, the trend is likely to become more prominent by mid-century, p...

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

The warming of Indian landmass has been confirmed through past climate records captured in depths of the earth.

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 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.

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. 

India will be among the worst hit countries that may face calamities like floods and heatwaves and reduced GDP.

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

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

The generation of hydropower from top seven hydropower projects in India has suffered due to climate variability in the past six decades. Future projected climate change may also hit reservoir operation for power generation from these projects, says the study done by researchers from the Indian Institute of Technology, Gandhinagar.

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. Now Indian scientists have developed a unique low-cost solar water purifier that can address all these concerns.

Increasing temperatures, decreasing rainfall and change in relative humidity adversely affect the famous Darjeeling tea production.

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

The maximum temperature in Kurseong has risen by 0.51 degree over the last 20 years while the total annual rainfall dropped by 56 mm and the relative humidity by 16.07 percent, leading to a decline in the overall production of Darjeeling tea in terms of green leaf production per hectare.
