Western Ghats a source of moisture for monsoon
A new study points out that the evapotranspiration from the vegetation over the Western Ghats accounts for one-quarter of the rainfall over peninsular India. Posted on 05 May, 2018 04:55 PM

The mountain range that runs along the west coast of peninsular India from Tamil Nadu through Kerala, Karnataka, and Goa to Maharashtra is known as the Western Ghats and is very well known for its majestic beauty. It is also among the top eight biodiversity hotspots in the world.

Uttarakhand braces itself for dry days
More than 1000 villages of the state are expected to be affected by a severe water crisis. Posted on 20 Apr, 2018 08:09 PM

Lokesh Verma, a farmer from Nainital’s Chanfi village, says this is the third year in a row that he is bearing losses in agriculture. “I have lost around Rs 2 lakh and there’s a debt of Rs 70,000 to pay off. I grow strawberries, guavas and peas in my 15 bighas of land, but there is not enough water in the hills to irrigate crops properly,” he says.

Indian monsoon recovers after decades of decline
Even if the total rainfall recovers, there is no indication that heat waves, droughts, extreme events and widespread floods are about to go away. Posted on 17 Apr, 2018 02:08 PM

As the parched Indian subcontinent eagerly awaits the monsoon, all indications are that it will be a normal monsoon, especially since no El Niño is in the offing for 2018.

Tourism increases black carbon in air
A study finds an increased concentration of black carbon in Gangotri region during tourist seasons. Posted on 16 Apr, 2018 03:25 PM

In a significant input for the growing debate on global climate change, a study by researchers at the Dehradun-based Wadia Institute of Himalayan Geology (WIHG) has found that there is a remarkable increase in the concentration of black carbon in the atmosphere near the pilgrim town of Gangotri in Uttarakhand during the two annual tourist seasons of April to June and during September and Octobe

How marine algae impact global climate, Indian monsoon
Phytoplankton are often early indicators of change in temperatures and can offer potential to extend the lead time of climate predictions. Posted on 05 Apr, 2018 06:37 AM

In a few weeks from now, the seasonal forecast for the Indian summer monsoon will be announced. Among various parameters that determine the fate of the monsoon is the sea surface temperature, more specifically, the contrast between land and sea temperatures. But what are the parameters that determine sea surface temperatures?

Climate change and its impact on water resources
Limiting global warming is crucial in controlling the ill effects of climate change like loss of water. Posted on 03 Apr, 2018 03:52 PM

The issue of economic development is intrinsically connected with global warming. The temperature of the planet rises because of indiscriminate exploitation of its resources and destruction of the environment. The effect of global warming further intensifies temporal and spatial variations in precipitation, melting of snow and water availability.

Anthropogenic warming and climate change
A study shows extreme rainfall events in India are linked to man-made emissions. Posted on 28 Mar, 2018 11:23 AM

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, particularly in southern and central India.
