Climate changes alter height of Himalayan range

THE AVERAGE height of the Himalaya was once much higher, the Ganga flowed much further north along the foothills and the Indus flowed east into the Ganga. All this changed about two million years ago -- not all that long ago in geological time. In the early 20th century, German …

Carbon sinks in mangroves and their implications to carbon budget of tropical coastal ecosystems

Nearly 50% of terrigenous materials delivered to the world's oceans are delivered through just twenty-one major river systems. These river-dominated coastal margins (including estuarine and shelf ecosystems) are thus important both to the regional enhancement of productivity and to the global flux of C that is observed in land-margin ecosystems. …

Thermodynamic regulation of ocean warming by cirrus clouds deduced from observations of the 1987 El Nino

Observations made during the 1987 El Niño show that in the upper range of sea surface temperatures, the greenhouse effect increases with surface temperature at a rate which exceeds the rate at which radiation is being emitted from the surface. In response to this 'super greenhouse effect', highly reflective cirrus …

A place in the sun

The UN sponsored discussions to prepare a global convention on climate began in February in USA. The aim is to prepare a legally binding convention to curb gaseous emissions leading to a much feared climate destabilisation. This convention is being seen as the world's greatest commitment to the environment and …

Global warming in an unequal world: a case of environmental colonialism

The idea that developing countries like India and China must share the blame for heating up the earth and destablising its climate, as espoused in a recent study published in the United States by the WRI in collaboration with the UN, is an excellent example of environmental colonialism. The report …

Assessment of urbanization effects in time series of surface air temperature over land

Records of hemispheric average temperatures from land regions for the past 100 years provide crucial input to the debate over global warming. Despite careful use of the basic station data in some of these compilations of hemispheric temperature, there have been suggestions that a proportion of the 0.5

Phenological trends with latitude in the mangrove tree Avicennia Marina

Leaf fall and reproductive phenology of Avicennia marina assessed during 1982-83 using litter fall collections from twenty-five sites in Australia, Papua New Guinea and New Zealand revealed major trends with latitude. Flowering shifted from NovemberDecember in northern tropical sites, to May-June in southern temperate sites. Periods between flowering and fruiting …

Cloud-radiative forcing and climate: Results from the earth radiation budget experiment

The study of climate and climate change is hindered by a lack of information on the effect of clouds on the radiation balance of the earth, referred to as the cloud-radiative forcing. Quantitative estimates of the global distributions of cloud-radiative forcing have been obtained from the spaceborne Earth Radiation Budget …

Pushkar: Prehistory and climatic change in Western India

Pushkar, near Ajmer, Rajasthan, lies in the dry zone to the east of the Indian desert. In the vicinity there is evidence for three arid phases, during the latter part of the Pleistocene, each represented by a major sand sheet and fossil desert dunes. The earliest contains lenses of detritus …

Coal-based power industry expands rapidly while solar power trots behind

Tuticorin, a coastal district in southern Tamil Nadu, is a large hub for coal-based thermal energy generation with many more such projects in the pipeline. Currently there are 2 power stations commissioned so far. The Tuticorin Thermal Power Station being the largest of them all, as of now, produces power …

Durban turning futile as EU buries head in sand

With the carbon market in doldrums, emerging economies like India will have to announce bolder schemes for a low carbon future The just-concluded Durban climate meet has been branded by many as a great saviour with even greater hopes being expressed for future. Reams have been written on how the …

Lanco's allies

Jonas Hamberg stumbles on fictitious companies dealing in public funds. It was all there on the Rajasthan Renewable Energy Corporation (RREC) website—names of companies, addresses and phone numbers. But calling them up did not work. We were to find out the reason later. I am talking about the companies that …

Solar energy is everybody's business

Solar mission is too important to let doubtful dealings hijack it. In public perception the renewable energy sector is a do-good sector that promises environment-friendly and affordable energy. It is for this reason that this sector gets overwhelming support from all sections of society. Civil society organisations, including the Centre …

Global Sustainable Development Goals: The Unresolved Questions for Rio+20
