Climate Change

No deal better than a weak deal

In negotiating the new climate change protocol in Copenhagen this month, we must not lose sight of our objective: to reduce the rate of annual global emissions so that we stay below the threshold of 450 parts per million for the concentration of greenhouse gases in the atmosphere.

Trends in the sources and sinks of carbon dioxide

Efforts to control climate change require the stabilization of atmospheric CO2 concentrations. This can only be achieved through a drastic reduction of global CO2 emissions. Yet fossil fuel emissions increased by 29% between 2000 and 2008, in conjunction with increased contributions from emerging economies, from the production and international trade of goods and services, and from the use of coal as a fuel source. In contrast, emissions from land-use changes were nearly constant.

Fog ahead? Met office messages on your mobile soon

Worried about driving blind on a foggy winter morning? Help will soon be an SMS away.

The weatherman has decided to start a service providing point to point information about fog and visibility through cellphone messages. The project will begin in Delhi and then be replicated in other parts of the country.

Shifts in Lake N:P stoichiometry and nutrient limitation driven by atmospheric nitrogen deposition

Human activities have more than doubled the amount of nitrogen(N) circulating in the biosphere. One major pathway of thisanthropogenic N input into ecosystems has been increased regionaldeposition from the atmosphere.

The human perturbation of the carbon cycle

The carbon cycle is closely linked to the climate system and is influenced by the growing human population and associated demands for resources, especially for fossil-fuel energy and land. The rate of change in atmospheric CO2 reflects the balance
between carbon emissions from human activities and the dynamics
of a number of terrestrial and ocean processes that remove

Oxygen level raised at Ladakh

LEH: Anyone visiting Ladakh for the first time can be left gasping for breath due to low oxygen levels in the high altitude region. But a successful plantation drive has brought about environmental changes-driving up oxygen content by 50% and, most unusually, making it rain, say Indian scientists.
