News articles on carbon dioxide
Mongabay.com news articles on carbon dioxide in blog format. Updated regularly.
(06/02/2011) As if being a major contributor to global warming wasn't enough, the increasing amount of carbon dioxide produced through human activity is also acidifying our oceans - and doing so more rapidly than at any other time in more than half a million years. New projections show that at current rates of acidification, clownfish and many species of algae may be unable to survive by 2100.
New record in global carbon emissions 'another wake-up call'
(05/31/2011) Global carbon emissions hit a new high last year proving once again that international political efforts, hampered by bickering, the blame-game, and tepidity, are failing to drive down the greenhouse gas emissions that are causing the planet to heat up. According to the International Energy Agency (IEA), following a slight fall in carbon dioxide emissions due to the economic downturn, emissions again rose to a new record level in 2010: 30.6 gigatons. This is a full 5 percent higher than the past record hit in 2008. The new record puts greater doubt on the international pledge of limiting the global average temperature rise to 2 degrees Celsius.
Greenpeace says McKinsey's REDD+ work could encourage deforestation
(04/07/2011) One of the world's top consultancies, McKinsey & Co., is providing advice to governments developing 'Reducing Emissions from Deforestation and Degradation' (REDD+) programs that could increase risks to tropical forests, claims a new report published by Greenpeace. The report, Bad Influence – how McKinsey-inspired plans lead to rainforest destruction, says that McKinsey’s REDD+ cost curve and baseline scenarios are being used to justify expansion of industrial capacity in Indonesia, Papua New Guinea, Democratic Republic of Congo, and Guyana.
'Huge reduction' of water from plants due to higher carbon levels
(03/30/2011) As if ocean acidification and a warming world weren't enough, researchers have outlined another way in which carbon emissions are impacting the planet. A new study shows that higher carbon dioxide levels in the atmosphere have taken a toll on how much water vapor plants release, potentially impacting the rainfall and groundwater sources. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that carbon dioxide levels over the past 150 years has reduced plants' spores, called stomata, by over one third (34%). This is important because stomata take in oxygen and carbon dioxide and release water vapor in a process dubbed 'transpiration'. Less stomata means less water driven into the atmosphere.
Amount of carbon absorbed by ecosystems each year is grossly overstated, says new study
(01/17/2011) According to a new paper published in Science, current carbon accounting methods significantly overstate the amount of carbon that can be absorbed by forests, plains, and other terrestrial ecosystems. That is because most current carbon accounting methods do not consider the methane and carbon dioxide released naturally by rivers, streams, and lakes. This new paper suggests that rivers, streams, and lakes emit the equivalent of 2.05 billion metric tons of carbon every year. (By comparison, all the terrestrial ecosystems on the world’s continents are thought to absorb around 2.6 billion metric tons of carbon each year). This is, as the lead author of the paper said, is a “major accounting error”.
Malaysia undermines commitment to protect Coral Triangle, backtracks on climate pledge
(12/22/2010) The Malaysian government will proceed with a plan to install a second-hand coal plant from China on the edge of the Coral Triangle in Borneo despite widespread condemnation from environmental groups and local people, reports Green SURF, a coalition that opposes the project.
New data shows REDD+ is succeeding
(12/15/2010) Amid the whirlwind of climate change news before and after the Cancún climate conference, including a landmark agreement on REDD+ (reducing emissions from deforestation, and related pro-forest actions), an important story seems to have passed by with little notice. Over the past two months, several new analyses have given clear evidence that deforestation has gone down over the past several years. In fact, the drop is quite impressive, and shows that of all the approaches to avoiding the worst consequences of global warming, reducing tropical deforestation is the one that has contributed by far the most to date.
Emissions from deforestation slow
(12/15/2010) A dip in forest clearing in Brazil combined with rising levels of industrial emissions have reduced the share of carbon dioxide emissions from deforestation to around 9 percent, according to research published last month in Nature Geoscience.
Carbon sequestration: Underground storage of carbon dioxide may trigger earthquakes
(12/14/2010) Underground storage of carbon dioxide may trigger earthquakes which could allow the gas to seep back into the atmosphere, rendering the emissions mitigation approach ineffective, warns Stanford geophysicist Mark Zoback.
Oil, indigenous people, and Ecuador's big idea
(11/23/2010) Ecuador's big idea—potentially Earth-rattling—goes something like this: the international community pays the small South American nation not to drill for nearly a billion barrels of oil in a massive block of Yasuni National Park. While Ecuador receives hundred of millions in an UN-backed fund, what does the international community receive? Arguably the world's most biodiverse rainforest is saved from oil extraction, two indigenous tribes' requests to be left uncontacted are respected, and some 400 million metric tons of CO2 is not emitted from burning the oil. In other words, the international community is being asked to put money where its mouth is on climate change, indigenous rights, and biodiversity loss. David Romo Vallejo, professor at the University of San Francisco Quito and co-director of Tiputini research station in Yasuni, recently told mongabay.com in an interview that this is "the best proposal so far made to ensure the protection of this incredible site."
2009 carbon emissions higher than expected
(11/22/2010) Despite a global economic recession and ongoing concerns about the impacts of climate change, last year's global carbon emissions were the second highest on record, according to the Global Carbon Project (GCP). Emissions in 2009 were just below the record emissions of 2008. In addition, 2009 emissions were higher than predicted, falling by only 1.3% from 2008 to 2009, instead of the predicted 2.8%.
It's not just size that matters: how population affects climate change
(11/11/2010) As the world's population increases, a surge in the number of older adults and the movement of people from the countryside to crowded cities will significantly affect levels of carbon dioxide emissions by 2050, according to a sweeping study published in the 11 October issue of the Proceedings of the National Academy of Sciences. A significant but attainable slowing of the planet's growing population could achieve up to 29 percent of the total decrease in emissions needed to stave off the harmful consequences of climate change by 2050, according to the study.
Carbon emissions hurting coral recruitment
(11/08/2010) While research has shown that ocean acidification from rising CO2 levels in the ocean imperils the growth and survival mature coral reefs, a new study has found that it may also negatively impact burgeoning corals, by significantly lowering the success of coral recruitment. A study in the Proceedings of the National Academy of Sciences (PNAS) has found that coral recruitment could fall by 73% over the next century due to increasing acidification.
US elects barrage of climate change deniers, threatening support for green energy
(11/03/2010) The US midterm election, which won Republicans the House but safeguarded the Senate for Democrats, has brought in a number of self-proclaimed climate change deniers, ending any likelihood that an energy bill will be passed over the next two years and essentially stumbling the White House's strategy on climate change. Newly elected Republican Senators Rand Paul of Kentucky and Marc Rubio of Florida, both members of the nascent Tea Party, have stated they do not believe in climate change despite that scientists overwhelming agree the Earth is warming due to human impacts.
Space tourism will worsen climate change
(10/24/2010) Have $200,000 to spend on a seat into space? You may want to re-think the expenditure given a new study in Geophysical Research Letters that shows space tourism will likely aggravate global climate change. Using sophisticated modeling, the researchers found that the biggest impact of a rise in space tourism on global temperatures won't be due to carbon emissions, but black carbon, often in the form of soot.
Majority of Americans confused on climate change basics
(10/17/2010) Most Americans don't understand the basics of climate change, according to a new poll by researchers with Yale. The poll found that over half of Americans deserve an 'F' on basic understanding of climate science and climate change, while only 1% would receive an 'A'.
U.S. government may finance massive coal projects in India, South Africa
(08/26/2010) The United States Export-Import Bank (Ex-Im Bank) voted on Wednesday to seek a final review of a $900m loan for a controversial 3,960 MW coal-fired power plant in India, reports Pacific Environment, a San Francisco-based environmental group.
The biology and conservation of declining coral reefs, an interview with Kristian Teleki
(08/15/2010) Coral reefs are often considered the "rainforests of the sea" because of their amazing biodiversity. In fact, coral reefs are one of the most diverse ecosystems on earth. It is not unusual for a reef to have several hundred species of snails, sixty species of corals, and several hundred species of fish. While they comprise under 1% of the world’s ocean surface, one-quarter of all marine species call coral reefs their home. Fish, mollusks, sea stars, sea urchins, and more depend on this important ecosystem, and humans do too. Coral reefs supply important goods and services–from shoreline protection to tourism and fisheries–which by some estimates are worth $375 billion a year.
Environmentalists and indigenous groups condemn plan for six dams in Peruvian Amazon
(06/21/2010) Environmentalists and indigenous groups have come together to condemn a 15 million US dollar plan for six hydroelectric dams in the Peruvian Amazon, signed last week by Brazilian President Luiz Inácio Lula da Silva and Peruvian President, Alan Garcia. While the six dams would produce over 6,000 megawatts, mostly for Brazil, critics say the dams will flood tens of thousands of hectares of rainforest, devastate the lifestyles of a number of indigenous groups, and only serve big Brazilian corporations.
Voluntary carbon markets plunge in 2009
(06/14/2010) Battered by a faltering world economy and lack of progress on U.S. climate legislation, voluntary carbon markets declined by nearly every measure in 2009, according to the fourth annual State of the Voluntary Carbon Market Report issued today by Ecosystem Marketplace and Bloomberg New Energy Finance.
Peatlands restoration wins support in effort to reduce carbon emissions
(06/10/2010) The body charged with establishing a framework for a global climate treaty will account for emissions from peatlands degradation, a source of roughly 6 percent of greenhouse gas emissions. The decision by the Intergovernmental Panel on Climate Change (IPCC) lays the groundwork for new measures to protect and restore wetlands, says Wetlands International.
US emissions from coal could be stopped in 20 years
(05/03/2010) A new study in Environmental Science and Technology (ES&T) concludes that the US could stop all emissions from coal-fired plants within 20 years time using only existing technologies and some that will be ready within the next decade. Such an accomplishment would go a long way toward lowering the US's carbon emissions and mitigating the impact of climate change, according to the researchers.
Close to a billion species: ocean exploration reveals shocking diversity of tiny marine life
(04/19/2010) Biologists worldwide may have to start re-evaluating their estimates of the number of species on Earth, since expeditions documenting the oceans' tiniest species have revealed shocking diversity: in the tens of millions of species, at least, and according to one researcher "closer to a billion". Fourteen field projects sent out by the Census of Marine Life focused on the oceans' smallest inhabitants: microbes, zooplankton, and tiny burrowing species inhabiting the deep sea bed. What they found was astounding.
Chaos and the Accord: Climate Change, Tropical Forests and REDD+ after Copenhagen
(04/06/2010) The Copenhagen Accord, forged at COP15 upended international efforts to confront climate change. Never before have 115 Heads of State gathered together at one time, let alone for the singular purpose of crafting a new climate change agreement. Even though the new Accord is still in intensive care, two things are already clear. First, we have entered an entirely new world. And second, tropical forests have the greatest potential to breathe life into the new agreement.
Analysis shows Borneo can say 'no' to coal power
(03/17/2010) Plans for a coal power plant in the Malaysian state of Sabah in northern Borneo have run into stiff opposition. Environmentalists say the coal plant could damage extensive coral reef systems, pollute water supplies, open rainforests to mining, and contribute to global climate change, undercutting Sabah's image as a 'green' destination. The federal government contends that the coal plant is necessary to fix Sabah's energy problems. However, a recent energy audit by the Renewable and Appropriate Energy Laboratory (RAEL) at the University of California Berkeley shows that pollution-intensive coal doesn't have to be in Sabah's future.
Massive methane leak in Arctic could trigger abrupt warming
(03/04/2010) Methane, a greenhouse gas 30 times more potent than carbon, is spewing from what was believed to be an impermeable barrier in Siberia in amounts equal to methane releases from the world's oceans. The discovery has lead researchers to fear the possibility of abrupt climate warming. According to the study published in Science, subsea permafrost below the East Siberian Arctic Shelf has become compromised, leaking vast amounts of methane into the atmosphere.
Amazon rainforest will bear cost of biofuel policies in Brazil
(02/08/2010) Business-as-usual agricultural expansion to meet biofuel production targets for 2020 will take a heavy toll on Brazil's Amazon rainforest in coming years, undermining the potential emissions savings of transitioning from fossil fuels to biofuels, warns a new paper published in the Proceedings of the National Academy of Sciences (PNAS). The research suggests that intensification of cattle ranching, combined with efforts to promote high-yielding oil crops like oil palm could lessen forecast greenhouse gas emissions from indirect land use in the region.
Obama pledges to reduce government emissions 28% by 2020
(01/31/2010) The U.S. government aims to cut its greenhouse gas emissions 28 percent by 2020 under an order announced Friday by President Obama.
New report: world must change model of economic growth to avert environmental disaster
(01/25/2010) For decades industrialized nations have measured their success by the size of their annual GDP (Gross Domestic Product), i.e. economic growth. The current economic model calls for unending growth—as well as ever-rising consumerism—just to remain stable. However, a new report by the New Economics Foundation (nef) states that if countries continue down a path of unending growth, the world will be unable to tackle climate change and other environmental issues.
Indonesian government report recommends moratorium on peatlands conversion
(01/19/2010) A study issued by Indonesian government recommends a moratorium on peatlands conversion in order to meet its greenhouse gas emissions target pledged for 2020, reports the Jakarta Post. The report, commissioned by the National Development Planning Agency (Bappenas), says that conversion of peatlands accounts for 50 percent of Indonesia's greenhouse gas emissions but only one percent of GDP. A ban on conversion would therefore be a cost-effective way for the country to achieve its goal of reducing carbon emissions 26 percent from a projected baseline by 2020. But the recommendation is likely to face strong resistance from plantation developers eager to expand operations in peatland areas. Last year the Agricultural Ministry lifted a moratorium on the conversion of peatlands of less than 3 meters in depth for oil palm plantations. Environmentalists said the move would release billions of tons of carbon dioxide.
Forest carbon conservation projects top $100 million
(01/14/2010) The market for carbon credits generated through forest conservation topped $100 million from 2007 through the first half of 2009, despite a global recession and plunging carbon prices in regulated markets, reports a new assessment by Ecosystem Marketplace.
Bottom-dwelling sea animals play surprising role in carbon sequestration
(01/07/2010) Researchers have long known that some marine animals, such as plankton, play big roles in the carbon cycle, but a new study shows that a long-ignored family of marine animals, the bottom-dwelling echinoderms, also do their part in the carbon cycle.
Scientists call for an end to mountaintop removal mining in the US
(01/07/2010) A group of scientists have called for the Obama Administration to place a moratorium on infamous mountain top mining due to "growing scientific evidence" of severe environmental degradation and serious impacts on human health, including cancer. The article, published in Science, is written by a dozen influential scientists, including hydrologists, ecologists, and engineers.
Underwater rocks could be used for massive carbon storage on America's East Coast
(01/05/2010) Considering it is unlikely that global carbon emissions will start dropping anytime soon, researchers are beginning to look at other methods to combat climate change. One of these is to hook polluting power plants up to massive carbon sinks where instead of the carbon going into the atmosphere it would be stored away in rocks. The process is known as carbon capture and storage or CCS. But before one can even debate the pros and cons of setting up CCS, scientists must see if high-quality sites exist.
Brazil to keep emissions reductions pledge despite failed climate summit
(12/30/2009) Brazil will honor its pledge to reduce greenhouse gas emissions 14-19 percent from 2005 levels despite the failure of this month's climate meeting in Copenhagen to establish binding limits on emissions, reports Reuters.
Coal plant could damage rainforest reserves, coral reefs, palm oil plantations in Malaysian Borneo
(12/20/2009) A proposed coal-fired power plant in Malaysian Borneo could damage the region's world-renowned coral reefs, pollute air and water supplies, open Sabah's biodiverse rainforests to mining, and undermine the state's effort to promote itself as a destination for "green" investment and ecotourism, warn environmentalists leading an effort to block the project. The scheme, which is backed by the federal Tenaga Nasional Berhad and state energy company, Sabah Electricity Sdn. Bhd, has faced strong opposition and already been forced to re-locate twice since it was conceived more than two years ago. The 300-MW plant is now planned for a coastal area that is situated in the middle of the Coral Triangle/Sulu Sulawesi Marine Ecoregion, an area renowned for astounding levels of biodiversity.
Climate change causing irreversible acidification in world's oceans
(12/15/2009) A new study from the Secretariat of the Convention on Biological Diversity has synthesized over 300 reports on ocean acidification caused by climate change. The report finds that increasing acidification will lead to irreversible damage in the world's oceans, creating a less biodiverse marine environment. Released today the report determines that the threat to marine life by ocean acidification must be considered by policymakers at the UN Climate Change Conference in Copenhagen.
Amazon cattle ranching accounts for half of Brazil's CO2 emissions
(12/12/2009) Cattle ranching accounts for half of Brazil's greenhouse gas emissions according to a new study led by scientists from Brazil's National Space Institute for Space Research (INPE).
Europe says US and China emission targets don't go far enough
(12/07/2009) At a press conference during the first day of the UN Copenhagen Climate Change Conference, the European Union has stated it will not raise its emissions cuts from 20 percent to 30 percent by 2020 (over 1990 levels) unless the US and China go further in their cuts.
Profile of the carbon footprint of the global poor: the challenge of alleviating poverty and fighting global warming
(12/07/2009) Two of the world's most serious issues—poverty and climate change—are interconnected. With a rise in one's income there usually comes a rise in one's carbon footprint, thereby threatening the environment. Wealthy nations have the highest per capita carbon footprints, while developing nations like India and China—which are experiencing unprecedented economic growth—are becoming massive contributors of greenhouse gases. However, it is those who have the smallest carbon footprint—the world's poor—who currently suffer most from climate change. Food crises, water shortages, extreme weather, and rising sea levels have all hit the poor the hardest.
Email scandal may be turning against climate change deniers
(12/07/2009) It may be that climate change scientists and policymakers have simply had enough, and it may be that the emails which were hacked did not reveal the massive conspiracy that they were supposed to, either way climatologists and politicians have gone on the offensive against claims that the hacked emails from the East Anglia's Climate Research Unit are evidence that climate change is a conspiracy or hoax.
Obama administration about to declare carbon dioxide a danger to the public, allowing regulation
(12/06/2009) The day before talks start in Copenhagen on a new international treaty to combat climate change, the Wall Street Journal reports that the Environmental Protection Agency (EPA) in the United States is set to declare carbon dioxide a 'public danger' as soon as Monday.
Highest rate of CO2 emissions growth since 1990
(12/04/2009) Between 1990 and 2005 Vietnam had the highest rate of emissions growth among countries that emitted more than 100 million tons of CO2 in any year during the past three decades, according to mongabay.com's analysis of emissions data from the Oak Ridge National Laboratory's Carbon Dioxide Information Analysis Center (CDIAC).
World leaders falling over themselves to show up at Copenhagen
(12/01/2009) If you’re a world leader and you won’t be in Copenhagen next week you might feel out of the loop. Currently 98 heads of state have agreed to attend the Climate Change Summit in Copenhagen—nearly half of the 192 member nations of the UN.
Americans throw away enough food every year to feed 200 million adults
(11/30/2009) The amount of food Americans throw away has risen by approximately 50 percent since 1974 according to a new study in PLoS ONE. American now waste on average 1400 calories per person everyday, equaling 150 trillion calories a year nationwide. Considering that the average person requires approximately 2,000 calories a day, this means that the US could feed over 200 million adults every year with the food that ends up in the trash. Currently, the UN estimates that one billion people—an historical record—are going hungry worldwide.
Zoos call for deeper emission cuts to save life on Earth
(11/30/2009) To save species around the world zoos say deeper emission cuts are needed than governments are currently proposing. Over 200 zoos worldwide have signed a petition calling on governments to set the target of atmospheric carbon below 350 parts per million (ppm) far lower than most government targets.
Reforestation effort would lower Britain's greenhouse gas emissions by 10 percent
(11/25/2009) A study by Britain's Forestry Commission found that planting 23,000 hectares of forest every year for the next 40 years would lower the island nation's greenhouse gas emissions by 10 percent, according to reporting by the BBC.
Land of plenty: 50 percent rise in the amount of food wasted in America worsens global warming, consumes freshwater
(11/25/2009) Just before Thanksgiving a new study shows that Americans are throwing away more food than ever. Since 1974 the amount of food Americans water per capita has risen by approximately 50 percent, according to a new study in PLoS ONE. Researchers found that food waste is adding to America's greenhouse gas emissions and accounts for over one quarter of the nation's freshwater consumption every year.
The US will set emissions target, but is this a turning point for success at Copenhagen?
(11/24/2009) Today may mark a turning point for a successful negotiation at the Climate Change Summit in Copenhagen or it may just be another blip in the up-and-down news cycles that have preceded the summit for months.
Deforestation emissions should be shared between producer and consumer, argues study
(11/19/2009) Under the Kyoto Protocol the nation that produces carbon emission takes responsibility for them, but what about when the country is producing carbon-intensive goods for consumer demand beyond its borders? For example while China is now the world's highest carbon emitter, 50 percent of its growth over the last year was due to producing goods for wealthy countries like the EU and the United States which have, in a sense, outsourced their manufacturing emissions to China. A new study in Environmental Research Letters presents a possible model for making certain that both producer and consumer share responsibility for emissions in an area so far neglected by studies of this kind: deforestation and land-use change.
