Carbon Dioxide

Sea ice helps carbon absorption

Sea ice helps carbon absorption

When the sea ice melts, our main concern has been sea-level and loss of habitat as our planet warms. Now we are also losing a valuable carbon dioxide sink, too, according to the latest and most detailed investigation yet.

Oceania sinks, and like New Zealand, we have to help

Oceania sinks, and like New Zealand, we have to help

In the Indian Ocean and the Pacific there are the volcanic islands of the Tahitian and Hawaiian archipelagos. Many other island nations based on coral atolls now live almost beneath the waves as our carbon emissions literally force global warming to drown them.

Even more carbon emitted from tropical forests!

Even more carbon emitted from tropical forests!

Have we got it right on this deforested planet? Are those carbon dioxide emissions becoming smaller or have we got it all wrong yet again? You've guessed it - we've been underestimating both the gases and the devious landowners.

What to do with CO2

What to do with CO2

The future is bleak, with vast fossil fuel emissions reducing very little. CCS seems always to be the excuse for energy companies to keep drilling, with government aid to help them store the global-warming emissions. As nuclear and renewable energies grow in importance, they still don’t seem capable of replacing fossils. As India’s new government under Nahendra Modi sets its sights on solar, perhaps we can see more large emitters becoming used to the idea of leaving the coal, oil and gas where it is.

Solar electricity comes to your home-free!

Solar electricity comes to your home-free!

When we see countries developing a large renewable energy capacity, the whole earth can celebrate that there will be no more carbon emissions from some sources at least. Now for the riddance of fracking, coal and all gas and oil based industries, before the UNs latest warnings become tragically true even before we know it.

Costing 21st Century coastal flooding

The carbon dioxide connection is finally obvious. Now we need to look ahead and prepare for the inevitable flooding that will happen as this last decade is followed by even quicker sea-level rise.

Pet coke expands, and pollutes everywhere

Pet coke expands, and pollutes everywhere



When nations export their fossil fuels, it is normally impossible to prescribe how much carbon dioxide (and the rest) will be released, stored or 'mitigated'. In this case, though, we should not be simply hiding our heads in the tar sand.

Sceptic tanks, of the non-thinking variety

Sceptic tanks, of the non-thinking variety

Scandalous behaviour from journalists as the UN tries to get action of carbon emissions. Some areas are refusing to see sense and insist on presenting controversy, when, in fact, there is no valid argument.

CCS or going renewable? The answer is now obvious

CCS or going renewable? The answer is now obvious



The battle within the carbon emission lobbies is probably over. The rush in China and Europe, especially, to develop more efficient renewable energies has overtaken the old ideas of capturing carbon dioxide and ''hiding it.''

Forest fuel may need rethinking

Forest fuel may need rethinking



Obtaining biofuel from forests has been shown to increase carbon emissions. Biofuel production is not without controversy; the food or fuel debate cannot be avoided in developing countries and the impact on water resources is unavoidable. The drive to find alternatives to fossil fuels has caused as many arguments as it has found solutions.

What was responsible for the end of the last ice age?

What was responsible for the end of the last ice age?

A previous explanation for the warming that ended the last ice age has been called into doubt. The last ice age was lengthy, taking place over a period of 25,000 years. It covered over a third of the earth and ended over 10,000 years ago. How the glacial period ended has been a matter of dispute, but one accepted theory was that a significant release of carbon dioxide from the ocean was the cause.

Socking it to soot could clean air and save ice caps

Socking it to soot could clean air and save ice caps



A Stanford University scientist is claiming that action on soot could have immediate and dramatic effects on slowing global warming, and reducing deaths from smoky air. The model being presented at the 242nd American Chemical Society meet suggests that soot is the second-biggest contributor to global warming - but that controlling it could be cheaper, and produce results faster, than the ongoing battle to reduce CO2.

Companies misleading over greenhouse super gases says report

Companies misleading over greenhouse super gases says report

One of the most powerful greenhouse gases is being released into the atmosphere in far higher quantities than European governments are reporting says a new report. HFC-23 is a so-called super greenhouse gas which has a global warming potential some 14,800 times higher than CO2.

How thawing permafrost can increase CO2 emissions and accelerate climate change

How thawing permafrost can increase CO2 emissions and accelerate climate change



As high-latitude permafrost thaws following climate change, a new study reveals that released CO2 can accellerate the process. Billions of tonnes of carbon are trapped in this permafrost and this will be released as the permafrost begins to thaw and early predictions were that the growth of the new vegetation would pull more carbon from the atmosphere than the permafrost would release.

Managed forests can soak up more carbon

Researchers discover that forests with younger, more diverse, species of trees are more effective at soaking up carbon than their older trees. Forests act as CO2 sponges, soaking up to 2.4 billion tonnes of greenhouse gases annually - almost a third of all CO2 released through the burning of fossil fuels each year.

Fire in the north: burning tundra heralds new warming worries

Fire in the north: burning tundra heralds new warming worries

A paper out in Nature today suggests that the touch-paper for runaway global warming could be lit by increased fires in the previously damp tundra soils of the Arctic. Such fires have been absent for 11,000 years - their reappearance could help cause permafrost to melt more readily, in a chain-reaction of CO2 emissions that would boost global warming.

Is carbon capture kaput?

Is carbon capture kaput?

News of AEP's cancellation of its carbon capture trial after mixed success have added to worries that CCS (Carbon capture and Storage) is struggling to match hopes for helping with the global carbon conundrum. And a new report into reusing CO2 - released yesterday by the UK's Center for Low Carbon Futures - is a reminder that potential their may also be too little too late.

Did icy-methane bring on the age of the dinosaur?

Did icy-methane bring on the age of the dinosaur?

The mass extinction 200 million years ago, that paved the way for the rise of the dinosaurs, could have been caused by a massive belch of methane, say scientists in a paper just published online on ScienceExpress. Plant remains show that the atmosphere was rapidly filled with carbon, which could have come from CO2-driven warming, releasing the methane stored in the cold sub-sea sediments.

Ocean acidification threatens coral reefs

Ocean acidification threatens coral reefs

Scientists look to volcanic fissures to examine the effects of rising acidification in the world's oceans. As the seas become more acidic through global warming and increased carbon dioxide levels, there's a real possibility that coral reefs and the sea life that relies coral reef habitat could become extinct by the end of the century.

Rising temperatures will affect forests carbon storage role says study

Rising temperatures will affect forests carbon storage role says study



As temperatures rise forest soils will store less carbon says a new study but, according to Jerry Melillo, trees may see carbon-storing growth spurts too. However, the increased temperature also speeded up the nitrogen cycle, enabling trees to store more carbon, partially offsetting the CO2 released from decaying matter in the soil.

Alaskan waters get new 'oceanic acidity monitors'

The announcement of 3 new advanced sensors for tracking oceanic acidity levels, made yesterday by the University of Alaska Fairbanks, will help scientists monitoring this worrying knock-on from rising CO2 levels. If CO2 levels keep pushing the ocean's acidity up, many organisms relying on limy shells will be threatened.

Climate change awareness down in Europe

Climate change awareness down in Europe



Carbon dioxide may be harmful to the environment, but it seems Europeans also believe it to be harmful to their health! Three quarters of those surveyed even considered CO2 to be ''unhealthy'', while 9% said they thought it was flammable and 18% believed it be a water pollutant, none of which is accurate.

Geoengineering is a leap from the fire into the frying pan



Recent geoengineering conferences have raised the profile of how we might tackle global warming with a Plan B - finding ways to cool the planet down, whilst trying to agree on how to cut those pesky CO2 emissions. But could the Plan B of geoengineering be a dangerous distraction that ultimately locks us into a series of even greater risks?

Much of ancient Martian atmosphere frozen at poles

Much of ancient Martian atmosphere frozen at poles

Mars may well have had a much denser CO2-rich atmosphere hundreds of thousands of years ago - one with wilder dust storms and that was more likely to support running water. That's the claim coming from a new analysis of satellite radar data over the Martian southern ice cap - published in Science today - which hints at a thick wedge of frozen CO2 there that contains 30 times the 'dry ice' of previous estimates.

'Radical' EU carbon tax is really taking baby-steps

'Radical' EU carbon tax is really taking baby-steps



The EU put forward its long-planned carbon tax this week, a move that will change energy taxes so that they are based on carbon emissions. Loud complaints are already being heard from car-makers and driver-lobby groups. But the new rules won't initially raise fuel prices at all. And that is the real worry, as fuel use ultimately needs to reflect the real cost to the planet - which means, in the end, prices for the worst polluting fuels will have to rise.

Damaged coastal wetlands means bad news for our climate

Damaged coastal wetlands means bad news for our climate

A new World Bank report has found that drainage and degradation of coastal wetlands leads to decreased carbon sequestration and increased amounts of carbon dioxide in the atmosphere. If coastal wetlands are drained, for example to convert the land for agricultural use, they emit large amounts of CO2 into the atmosphere

Research casts light on planet's future

Research casts light on planet's future



The study of fossilised mollusks could give scientists an invaluable insight into the way the world will respond to climate change. Researchers at Californian university UCLA say that examining the fossils from 3.5 million years ago has allowed them to build a picture of how the world is reacting to current levels of atmospheric carbon dioxide, a key contributor to global climate change.

UK Government blames home users as greenhouse gases figures rise

Greenhouse gas emissions rise in the UK. While the figures from the transport sector were stable, the government was quick to highlight that the bulk of the increase came from the residential sector, despite the fact that just 17% of all CO2 emissions comes from the nation's homes.

Recession pulled US greenhouse gases down in 2009

Recession pulled US greenhouse gases down in 2009



A 6% fall in CO2 equivalent emissions is the eye-grabbing figure from the EIA report for 2009 - a record-breaking drop. But that number is muddied by the contrasting effects of the recession, which pulled production, and so emissions, down sharply. But the reported continued decrease in carbon intensity offers a glimmer of hope for 2010.

Record-breaking 2010 Amazon drought seen from space

Record-breaking 2010 Amazon drought seen from space

Last summer's drought in the Amazon left vast swathes of forest visibly stressed, according to a study of images from 2 NASA satellites. This worryingly matches the predictions of drier, harsher times for one of the world's most biodiverse areas - and sets the scene for possible massive outpouring of CO2.

Jet contrails major contributor to aviation's effect on climate

Jet contrails major contributor to aviation's effect on climate

Cirrus clouds generated from the contrails of jets may be the cause of more atmospheric warming today than all the CO2 emitted by the aviation industry since the beginning of flight. Aviation is responsible for about 5% of man-made climate change effects, and that proportion could triple by 2050 according to some projections. Least understood is the role of aircraft exhausts in forming clouds.

Cut CO2 and the rains will flow

Cut CO2 and the rains will flow



Decreasing CO2 concentrations in the atmosphere causes more rain to be wrung from the clouds, according to research published in Geophysical Research Letters. That change in rainfall can go both ways, with decreasing precipitation as CO2 levels rise - and it happens faster than the overall global change in temperature.

SuperHomes are Open to Visitors

SuperHomes are Open to Visitors

Spring Opening for old houses that have been transformed into super low emissions properties. What is a SuperHome and does it wear a cape?  The answer to that is fairly clear: no it doesn't; in fact a SuperHome looks pretty much like an ordinary home, except it may have solar panels on the roof. It is inside that it is different. SuperHomes are homes that have reduced their their carbon emissions by at least 60%.

Destroyed and degraded coastal marine ecosystems increasing global carbon emissions

Destroyed and degraded coastal marine ecosystems increasing global carbon emissions

According to the new Blue Carbon Working Group, urgent action is needed to halt increasing carbon emissions from destroyed and degraded coastal marine ecosystems.

Biofuels may not be as green as you might think - new study sheds light on 'con'

Biofuels may not be as green as you might think - new study sheds light on 'con'

Biofuels produced in Africa but destined for use in Europe will result in up to six times the carbon emissions of fossil fuels, according to a new report. Some species of the succulent Jatropha genus are widely promoted as easily grown crops, and oil from the seeds is used extensively in many developing countries to produce biofuel. However, the new report contradicts the 'green image' of biofuels, which are widely considered to be a renewable alternative to fossil fuels.

Are we in the first 'hyperthermal' for 40 million years?

Are we in the first 'hyperthermal' for 40 million years?

Starting 50 million years ago, repeated spikes in temperature pushed life on earth to the brink. Now new research published in Nature has shown that these hyperthermals were more common at that time than originally thought. With these events being linked to massive outpourings of CO2, they may have much to teach us, as we head into the first hyperthermal in tens of millions of years.

Going back to nature builds carbon stocks for Australian farmers

Going back to nature builds carbon stocks for Australian farmers



A report on the healing potential of Natural Sequence Farming, in repairing wounded carbon and water cycles, has been published in the latest International Journal of Water. Not only can NSF help restore fertility in a sustainable way for the Australian landscape studied - by building up carbon stores in the soil, CO2 is drawn from the atmosphere, so blunting emissions-driven climate change.

Buying local produce can cause more emissions that importing food

Buying local produce can cause more emissions that importing food

Buying local produce can cause more emissions that importing food from abroad. The fact is the energy that goes into produce not indigenous to the local environment can be vastly greater than what is required in the natural country of origin. In order to thrive in the non-indigenous locality, many foodstuffs require the addition of other elements over its life cycle, most notably heat, resulting in higher CO2 emissions than if the produce was transported from the traditional country of origin. Filed under environment: Emissions/Business.

Tibetan Plateau soot damage driving stronger monsoons



Researchers have found that the effect of soot - rising from the newly industrialised economies of Asia - could have an even more damaging effect on the climate than CO2 in the Himalayas. Researchers at the Department of Energy's Pacific Northwest National Laboratory, the Universityof Michiganand NOAA looked at the effect of soot on the Tibetan Plateau in the Himalayasand found that soot is a worse offender in climate change than CO2.

China not on board with CO2 - why a 16% cut means rising emissions

China not on board with CO2 - why a 16% cut means rising emissions



China's Premier pledged Sunday to cut carbon emissions intensity, by over 16% for the next 5 years. Whilst such a number sounds impressive, when it comes to global warming it's the total emissions that matter. There the story is not so promising. Whilst this pledge is part of a 20-year plan to reduce carbon intensity by 40-45% by 2020, relative to 2005, reducing the intensity of emissions is not the same as reducing total emissions.

Scott's Antarctic work lives on in new carbon survey

Tiny Antarctic organisms are growing more quickly because of an increase in carbon say scientists who used the polar legend's century's old collections. Scientists have been examining tiny creatures called bryozoans. These sea-bed dwellers feed on microscopically small marine plants called phytoplankton, which need carbon dioxide to survive.

New farming methods to reduce greenhouse gases and improve yields

New farming methods to reduce greenhouse gases and improve yields



By drilling a field in foot wide strips, nine inches deep, and planting maize and adding nitrate fertiliser at the same time, this increases yields and reduces the amount of nitrate escaping into the atmosphere as nitrous oxide. Although carbon dioxide (CO2) is widely held to be the major contributor to global warming, scientists believe that the contribution of nitrous oxide (N2O) is about 300 times more than CO2.

Droughts may turn Amazon Rainforest into major polluter, scientists warn

Droughts may turn Amazon Rainforest into major polluter, scientists warn

Should droughts in the Amazon Basin become more frequent, the days of the rainforest offsetting man-made carbon emissions are set to come to an abrupt end. The days of the Amazon Rainforest acting as a natural buffer against man-made carbon emissions may be drawing to a close. In fact, not only could the South American forest soon lose its status as the planet's most-important 'carbon sink'

Electric dreams? or is there a drive towards electric vehicles

Electric dreams? or is there a drive towards electric vehicles



The drive towards electric vehicles pick up speed. China is set to create at least 10 million electric car charging points by 2020. A heavy dependence on foreign oil, plus significant CO2 levels are leading the country to push towards a more environmentally friendly transport infrastructure.

Climate tax on meat and milk could help reduce Europe's carbon footprint

Climate tax on meat and milk could help reduce Europe's carbon footprint

Asking consumers to pay the 'true climate cost' of meat and other dairy products could lead to a severe reduction in carbon emissions, Swedish scientists have argued. While, for the most part, these 'carbon taxes' are levied on businesses operating in the manufacturing and transportation sectors, new research suggests that they could be equally effective, if not more so, if targeted towards the agriculture and food industries.

Air India has announced significant reductions in carbon dioxide emissions after using engine washing technology developed by an American company. The airline says that it has performed 124 washes using Pratt & Whitney's EcoPower technology, saving more than 540,000 gallons of fuel worth $1.9 million and reducing carbon dioxide (CO2) emissions by 5,300 metric tons.

History may hold the key to future climate change consequences

History may hold the key to future climate change consequences

By looking to the past, one team of US scientists believe they can map out the likely changes to the Earth's climate ongoing rises in carbon emissions will bring. one team of US researchers has been looking to the past in order to gain an understanding of the potential consequences of the major rise in the volume of carbon dioxide in the Earth's atmosphere seen since the dawn of the Industrial Revolution. Specifically, the experts at the National Center for Atmospheric Research in Boulder, Colorado, have been asking: When was the last time the Earth's atmosphere contained as much carbon dioxide as it may by the end of this century?

Cancun delegates should adjust to reality of 4°C temperature rise

A collection of new papers welcoming world leaders to Cancun effectively argue that this latest round of climate change talks should be seen almost as a damage limitation exercise. Up to one billion people around the world are set to lose their homes over the next 90 years as a result of ongoing failures to cut back on carbon emissions.
