Even if carbon dioxide emissions came to a sudden halt, the carbon dioxide already in Earth's atmosphere could continue to warm our planet for hundreds of years, according to Princeton University-led research published in the journal Nature Climate Change. The study suggests that it might take a lot less carbon than previously thought to reach the global temperature scientists deem unsafe.
NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world.
A discovery at the University of Wisconsin-Madison may represent a significant advance in the quest to create a "hydrogen economy" that would use this abundant element to store and transfer energy.
Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth’s atmosphere.
Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, claims new research from the University of Waterloo recently published in the International Journal of Modern Physics B.
Researchers 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.
Emissions from coal power stations could be cut drastically by a new, energy-efficient material that adsorbs large amounts of carbon dioxide, then releases it when exposed to sunlight.
Earth's repeated flip-flopping between greenhouse and icehouse states over the past 500 million years may have been caused by volcanoes at particular spots where enormous amounts of carbon dioxide are released into the atmosphere.
The discovery that sea urchins use nickel particles to remove carbon dioxide from the sea could be the key to capturing tonnes of CO2 from the atmosphere.
An international team of researchers studying data beamed back by NASA's Mars Reconnaissance Orbiter have observed seasonal changes on far-northern sand dunes on the Red Planet caused by warming of a winter blanket of frozen carbon dioxide.
As soil warms from climate change, it releases additional carbon into the atmosphere – but that effect diminishes over the long term, say scientists.
Many governments are still failing miserably to keep global carbon emissions low enough to limit global warming to the two-degree-Centigrade international target.
The permafrost covering almost a quarter of the northern hemisphere contains twice as much carbon as is currently in the atmosphere, and could significantly amplify global warming should thawing accelerate as expected.
The first hard evidence has emerged that the shells of marine snails in the seas around Antarctica are being dissolved by ocean acidification.
Concentrations of greenhouse gases in our atmosphere, driven by man-made carbon emissions, reached a record high in 2011, according to the World Meteorological Organisation (WMO).
Rising levels of carbon dioxide in the atmosphere are leaking out to the edge of space and interfering with satellites, new research shows.
Scientists at the University of Melbourne have developed a new way of capturing carbon dioxide that should reduce the cost of separating and storing the gas.
Scientists at the US Naval Research Laboratory are developing a process to extract carbon dioxide from seawater and use it to produce hydrogen gas, which can then be catalytically converted into jet fuel.
NASA's Mars Reconnaissance Orbiter (MRO) has returned the first definitive evidence of carbon dioxide snowfalls on Mars - the only place this is known to happen anywhere in our solar system.
Sea otters are an up-to-now unsuspected ally in the fight against global warming, say scientists from UC Santa Cruz.
