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.

Rise in Arctic temperatures linked with extreme weather events

A new study has demonstrated that the swift rise in the Arctic temperatures is because of weather extremes in the northern hemisphere such as heatwaves in the US and flooding in Europe.

NASA to launch satellite to track carbon pollution

The US space agency is to launch on Tuesday a satellite that tracks atmospheric carbon dioxide, a leading greenhouse gas that contributes to global warming.

How earth`s atmosphere allowed life to evolve

Scientists may have discovered a mechanism to help determine how oxygen levels in the atmosphere expanded to allow life to evolve.

Reducing emissions is primary way to fight climate change: Study

Researchers have said that reducing emissions will be the primary way to fight climate change.

Causes, consequences of global climate warming 56 mn years ago revealed

Researchers are studying the causes and consequences of global climate warming that took place 56 million years ago.

Jurassic period had five times more CO2 than today

Around 250 million years ago when dinosaurs roamed the earth, the earth had five times more carbon dioxide (CO2) than today, research shows.

New greenhouse gas has higher global warming impact than CO2

A long-lived man-made greenhouse gas that appears to have the highest global-warming impact of any compound to date has been discovered.

New grass developed to curb greenhouse gas emissions

A new kind of grass has been developed with the joint efforts of scientists from Japan and Colombia to curb greenhouse gas emissions caused by chemical fertilisers.

Greenhouse gas in atmosphere hits new record: UN

The amount of greenhouse gases in Earth`s atmosphere hit a new record high in 2012, continuing an ever-faster rise that is driving climate change, the UN weather agency said Wednesday.

Satellites reveal rise in Earth`s carbon dioxide emission

Ten years of satellite observations of greenhouse gases have revealed the rise of carbon dioxide in the atmosphere.

Highly effective method for converting CO2 into methanol developed

Universite Laval researchers have developed a highly effective method for converting CO2 into methanol, which can be used as a low-emissions fuel for vehicles.

Engineered bacteria use hydrogen, CO2 to produce electricity

Researchers including one of Indian origin have engineered a strain of electricity-producing bacteria that can grow using hydrogen gas as its sole electron donor and carbon dioxide as its sole source of carbon.

New technique discovered to make fuel from CO2 in air

Researchers have found a way to transform the carbon dioxide (CO2) trapped in the atmosphere into useful industrial products.

New tech needed for curbing CO2 at source

Reducing carbon dioxide emissions alone may not be enough to curb global warming. There is a need to develop technologies that remove large amounts of the gas at the source, say researchers.

Stripping air of CO2 may become unavoidable

Researchers argue that upfront costs of directly taking carbon out of the air will be expensive.

Eating wisely can lower carbon footprint: Study

Consumers can help curb greenhouse gas emissions by reducing the quantity of food they buy, serve and waste, a study says.

Tweaking copper to recycle CO2 into fuel

Copper is one of the few metals that can turn CO2 into hydrocarbon fuels with little energy and also cut down on emissions.

CO2 turns clownfish into drunken daredevils

Carbon dioxide in the ocean acts like alcohol on fish and leaves them less able to judge risks, making them prone to losing their senses, a new study has claimed.

Pledges to cut CO2 will go on: UN official

The top UN climate official said Saturday she is confident industrial countries will renew their pledges to cut greenhouse gas emissions after their current commitments expire next year.
