Sunlight, not bacteria, key to CO2 in Arctic

Sunlight and not bacteria is the key to triggering the production of carbon dioxide (CO2) from material released by Arctic soils, says a significant study.

Fuel cell technology gets a boost

In an impetus for fuel cell technology to build "smart" cars, scientists at Stanford University have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis.

`Sponge` plastic to soak up CO2, reduce pollution

You have blamed plastics all along for increased pollution but researchers have now made a material - inspired by the plastics used in food containers - that soaks up carbon dioxide (CO2).

Sunderbans mangrove trees losing capacity to absorb CO2: Study

The vast mangrove forest in the Sunderbans is fast losing its capacity to absorb carbon dioxide, one of the main greenhouse gases, from the atmosphere due to rise in the salinity of water, rampant deforestation and pollution, a study has found.

Mars 2020 rover will carry tools to make oxygen

The suite of space-age tools loaded on NASA`s next robotic vehicle, bound for the Red Planet in 2020, will include a device for making oxygen out of carbon dioxide.

Artist develops first ever man-made leaf that could provide oxygen during space travel

In a path-breaking innovation, Royal College of Art graduate Julian Melchiorri developed the first man-made, biologically functional leaf that takes in carbon dioxide, water, and light and releases oxygen.

Carbon dioxide can be future fuel source

In a significant breakthrough, scientists have synthesised a catalyst that improves the system for converting waste carbon dioxide into syngas -- a precursor of gasoline and other energy-rich products.

`Natural cooling fluctuation` masked greenhouse effect during last decade: Study

A new study has revealed that a natural cooling fluctuation between 1998 and 2013 largely masked the warming effects of a continued increase in man-made emissions of carbon dioxide and other greenhouse gases.

Plants` size, age impact productivity more than climate

A new study has revealed that the size and age of plants has more impact on their productivity instead of climate that has a relatively minor direct effect on net primary productivity.

Ants can trap carbon for us

The tiny ants may be derided by all, but they play a very important role in making the earth habitable by assisting in the gradual reduction of atmospheric carbon dioxide.

NASA`s Orbiting Carbon Observatory-2 blasts off on Delta II rocket

NASA has launched its first satellite to measure carbon dioxide, Orbiting Carbon Observatory-2, aboard a Delta II rocket early Wednesday, July 2 in California .

Ancient ocean currents may have changed pace and intensity of ice ages

Researchers have long tried to explain why ice-age cycles became longer and more intense some 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles.

Development in India and China adds to the CO2 emission: Obama

The fast developing economies of India and China are adding to the emission of carbon dioxide, US President Barack Obama has said asking Americans to be ready and adopt more and more green technologies.

Warming climate adding to CO2 levels released by oceans: Study

A new study has revealed that increase in warming climate has intensified the carbon dioxide level in atmosphere which is released by oceans.

Fewer US nuclear plants could curb climate change fight

Nuclear power plants in the United States increasingly risk closure amid growing competition from cheap natural gas, which experts said could hamper President Barack Obama`s efforts to combat climate change.

Carbon emission: Know all about it

As the name suggests, it is manly the amount of Carbon dioxide (CO2) emitted into the atmosphere including many gases that negatively influence the quality of the air subsequently increasing the greenhouse effect.

Semi-arid areas could become carbon sinks: Study

Semi-arid areas on the planet could become carbon sinks in the future despite the fact that they hold the carbon for a short period compared to tropical forests, according to a study in Australia published Thursday.

Why Antarctica isn`t warming as much as other continents

Researchers have explained why Antarctica is not warming as much as other continents, and why southern Australia is recording more droughts.

Rising CO2 level poses threat to human nutrition

The rising levels of atmospheric carbon dioxide that comes with climate change poses serious threat. According to a new study it has been revealed that the rising CO2 can cut the nutritional quality of some of the world`s most important food crops.

Soil microbes play role in increasing rate of climate change

Researchers have found increased levels of carbon dioxide in the atmosphere cause soil microbes to produce more carbon dioxide, accelerating climate change.
