Step up action to curb global warming, or risks rise - UN

A United Nations report said on Sunday that governments must act faster to keep global warming in check and delays until 2030 could force them to use little-tested technologies to extract greenhouse gases from the air. The study, drawing on work by more than 1,000 experts, said a radical shift …

Act fast to curb global warming, or extract CO2 from air -UN

Faster action is needed to keep global warming to agreed limits and delays until 2030 could force reliance on technologies to extract greenhouse gases from the air, a U.N. report said on Sunday. The study, drawing on the work of more than 1,000 experts, said a shift from fossil fuels …

Climate change 2014: mitigation of climate change - summary for policymakers (IPCC Climate Report, Fifth Assessment, WGIII AR5)

The Working Group III contribution to the IPCC’s Fifth Assessment Report (AR5) assesses literature on the scientific, technological, environmental, economic and social aspects of mitigation of climate change. It builds upon the Working Group III contribution to the IPCC’s Fourth Assessment Report (AR4), the Special Report on Renewable Energy Sources …

CO2 emission by urban households 16 times more than rural ones: Report

Only 6.4 per cent and eight per cent of Scheduled Tribe and Scheduled Caste households are using clean fuel in rural parts. A report by the International Institute of Population Sciences (IIPS), Mumbai, shows that the per capita emission of carbon dioxide by urban households is a shocking 16 times …

The end of China's coal boom

This new report released by Greenpeace’s East Asia office focuses largely on coal-control policies issued by the central government in China and resulting pledges of coal limits in 12 of the country's 34 provinces, accounting for 44 percent of its coal consumption.

Shell, Unilever Seek 1 Trillion-Ton Limit on CO2 Output

Royal Dutch Shell Plc (RDSA) and Unilever NV (UNA) joined 68 other companies in urging world governments to cap cumulative carbon emissions since the industrial revolution to 1 trillion metric tons to contain rising temperatures. The emissions cap is needed to stabilize the increase in temperatures since the 19th century …

Leaked IPCC climate plan to worsen global warming - ecologists

Critics say bioenergy, carbon capture, among draft report's 'false solutions' to sustain business as usual economics A British environmental organisation that has reviewed the draft of a forthcoming UN IPCC report on mitigating climate change has questioned many of the document's recommendations as deeply flawed. Dr Rachel Smolker, co-director of …

Global warming could be accelerated by permafrost thawing

Researchers have found new evidence that permafrost thawing is releasing large quantities of greenhouse gases into the atmosphere via plants, which could accelerate warming trends. Suzanne Hodgkins, the lead author on the paper and a doctoral student in chemical oceanography at Florida State, said they've known for a while now …

Arid areas absorb unexpectedly high amounts of atmospheric carbon

A new research, conducted over a period of ten years in Mojave Desert, has found that arid areas absorb an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere. The findings give scientists a better handle on the earth's carbon budget-how much carbon remains in …

EPA chief says power plant rule will be tough, enforceable

The U.S. Environmental Protection Agency's chief said on Monday that new carbon pollution standards due in June will be flexible enough for all states to meet but will be environmentally stringent and federally enforceable. EPA Administrator Gina McCarthy gave her first remarks since the agency sent its proposed rule, which …

Nutritional quality of food crops decreases as CO2 levels rise

A field test has demonstrated for the first time that elevated levels of carbon dioxide restrict plants' ability to transform nitrate into proteins, indicating that the nutritional quality of food crops is at risk as climate change intensifies. Findings from this wheat field-test study, led by a UC Davis plant …

Carbon cuts possible for manageable warming: Experts

The world, acting urgently, can curb carbon emissions enough to avert worst-case scenarios for climate change, UN experts said on Monday as envoys met in Berlin to weigh the options for action. "The literature here shows that deep cuts in greenhouse gas emissions to limit warming to 2 C... remain …

Time running out to meet global warming target: U.N. report

Government officials and top climate scientists will meet in Berlin from April 7-12 to review the 29-page draft that also estimates the needed shift to low-carbon energies would cost between two and six percent of world output by 2050. It says nations will have to impose drastic curbs on their …

Time running out to meet global warming target: UN report

OSLO: World powers are running out of time to slash their use of high-polluting fossil fuels and stay below agreed limits on global warming, a draft UN study to be approved this week shows. Government officials and top climate scientists will meet in Berlin from April 7-12 to review the …

Rising carbon dioxide level affecting food quality

Rising carbon dioxide level in the atmosphere is lowering protein in key dietary crops which may affect the nutritious value of foods, a new study has warned. For the first time, a field test has demonstrated that elevated levels of carbon dioxide inhibit plants' assimilation of nitrate into proteins, indicating …

IPCC report proposes sucking carbon out of the air as climate fix

Technique of burning biomass then pumping released carbon underground included in leaked draft from UN climate panel An upcoming UN report suggests that unproven technologies to suck carbon out of the air might be a fix for climate change, according to a leaked draft obtained by the Guardian. Scientists and …

The latest edition of this authoritative annual report tells the story of the latest developments, signs and signals in the financing of renewable power and fuels. Packed full of statistics, charts and illuminating narrative, it explores the issues affecting each type of investment, technology, region. According to Global Trends in …

Tropical Pacific Ocean Acidification Occurring Much Faster Than Expected, NOAA Finds

Change is taking place in the tropical Pacific Ocean, where NOAA (National Oceanic and Atmospheric Administration) researchers have found that carbon dioxide (CO2) concentrations have increased as much as 65 percent faster than atmospheric CO2 since 1998. Rising CO2 concentrations of this magnitude indicate that tropical Pacific waters are acidifying …

EU drops plan to extend CO2 rules to international flights

The European Parliament on Thursday voted to exempt international flights from paying for their carbon emissions following intense pressure from national governments not to extend current rules beyond domestic air travel. On Thursday the European Parliament voted by 458 votes to 120 to back a proposal which would limit the …

Recent Reports Show Need for Congress to Act on Climate Change

The Intergovernmental Panel on Climate Change, a United Nations task force, released a report last week that was seven years in the making.
