Carbon removal using ‘blue carbon’ habitats “uncertain and unreliable”
New study from the University of East Anglia challenges the widely held view that restoring areas such as mangroves, saltmarsh and seagrass can remove large amounts of carbon dioxide (CO2) from the atmosphere

Warming waters will lead to gasping rivers in India
Indian rivers are experiencing rising temperatures, which can lower the oxygen carrying capacity of their waters and spell doom for living organisms, small and large living in the waters.

Damned by pollution, doomed by beautification
The River Front Development project planned by the PMC is nothing but a cosmetic makeover for the already choked Mula Mutha river in Pune, argues Dr Gurudas Nulkar while speaking to the India Water Portal.

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.

Disasters managers and scientists in Sikkim are keeping a close watch on a lake formed due to the melting of glaciers to see how successful is an experiment they began two years back to siphon off excess water from the lake to prevent it from bursting.

Kerala floods and after
The reason behind Kerala floods is a lot more than what the CWC wants us to believe.

Every time there is a huge flood in India with massive loss of lives and extensive physical damage, there is a hue and cry. Especially, if this takes place in an area not normally prone to such floods. Assam and Bihar, for instance, are regularly laid waste by floods and so, there is not much agitation over that anymore.

Is it drought after flood for Kerala?
Kerala has begun to see the result of years of environmental neglect and mindless exploitation of natural resources.

If the devastating floods were not enough, the state of Kerala is witnessing further signs of environmental neglect and greedy exploitation of natural resources. There has been a drop in the water level, particularly in those rivers which were flooded recently. It is also reflected in the drying and caving of wells in different parts of the state.

Linking weather extremes with climate change
Detection and attribution in case of extreme weather events play an important role in understanding climate change better.

Every time an extreme weather event like the Kerala floods occurs, there is a great demand for information on its causes. The question uppermost in public discourse is if such events can be attributed to climate change and global warming.
Whether an extreme weather event can be attributed to climate change or not is a question that has been on the minds of scientists for long. (Photo: IWP Flickr photos)

More water for crops
Subsidies given for irrigation efficiency may have a negative impact on water use.

A new study has pointed out that increased irrigation efficiency does not translate to more water availability for other uses at the watershed level. The subsidies for increasing irrigation efficiency are intended to increase crop production as well as more return flow from irrigated areas that can be allocated to urban, domestic and industrial uses.
