Ship pollution curbs to stoke global warming – study
Shipping is slowing climate change by spewing out sunlight-dimming pollution but a clean-up needed to safeguard human health will stoke global warming, experts said on Friday.
“So far shipping has caused a cooling effect that has slowed down global warming,” Jan Fuglestvedt, of the Center for International Climate and Environmental Research Oslo (CICERO), told Reuters.
“After some [...]
“Supervillain” CO2 has “henchmen” like NO2 and methane to amplify global warming
Washington, September 9 (ANI): Scientists have said that in the fight against global warming, “supervillain” carbon dioxide (CO2) should not be solely targeted, as there are harmful greenhouse gases like nitrous oxide (N2O) and methane, which are the “henchmen” of CO2.
According to a report in National Geographic News, several “henchmen” gases-some even more [...]
World’s ecosystems can have key role in countering climate change
Washington, September 3 (ANI): A new research has determined that investing in restoration and maintenance of the Earth’s multi-trillion dollar ecosystems can have a key role in countering climate change and [...]
Risky climate-fixing methods needed unless CO2 emissions are greatly reduced
Sydney, Sept 2 (ANI): Scientists have warned that potentially dangerous and unproven geoengineering technologies might be needed to fix the climate in the near future, unless emissions of carbon dioxide (CO2) can be greatly reduced.
According to a report by ABC News, the stark warning, made by scientists in a report by the Royal Society, UK, [...]
Living, breathing megacities play major role in global climate change
Washington, August 19 (ANI): In a new scientific model, researchers have compared megacities to living, breathing organisms to foster a deep new understanding of how poor air quality in megacities can harm residents, people living far downwind, and also play a major role in global climate change.
This is the conclusion of a report on the [...]
Ozone depletion reduces CO2 uptake of Southern Ocean
Washington, August 9 (ANI): In a new research, scientists have determined that depletion in the ozone layer is reducing the atmospheric carbon dioxide (CO2) uptake of the Southern Ocean.
Most current models predict that the strength of the Southern Ocean CO2 sink should increase as atmospheric CO2 rises, but observations show that this has not been [...]
CO2 not only reason for curious spike in Earth’s temperature 55 million years ago
Washington, July 16 (ANI): A new research has left scientists puzzled as it indicates that something other than carbon dioxide (CO2) was also responsible for a curious spike in Earth’s temperature 55 million years ago.
Over the past couple of decades, researchers have been gathering data about a mysterious event known as the Paleocene-Eocene Thermal [...]
Environment Minister rejects use of climate factor as a non-tariff barrier
New Delhi, June 30 (ANI): Union Minister for Environment and Forests Jairam Ramesh on Tuesday ruled out to use climate as a non-tariff barrier and any attempt to introduce climate change as a topic for discussion at the World Trade Organisation (WTO) meetings.
Jairam’s [...]
Rise in CO2 levels 200 mln yrs ago led to sudden collapse in plant biodiversity
Washington, June 19 (ANI): In a new study, scientists have found that a rise in carbon dioxide (CO2) levels 200 million years ago led to a sudden ancient collapse in plant biodiversity.
The evidence for the collapse in the plant biodiversity was unearthed by scientists in the form of 200 million-year-old fossil leaves collected in East [...]
Scientists develop formula to reduce methane gas in cattle
Washington, May 8 (ANI): University of Alberta researchers have developed a formula to reduce methane gas in cattle, which is a threat to the environment.
By developing equations that balance starch, sugar, cellulose, ash, fat and other elements of feed, a Canada-wide team of scientists has given beef producers the tools to lessen the methane gas [...]
Greenpeace tells major emitters to move from words to deeds
New Delhi/Washington, Apr.28 (ANI): As senior diplomats and politicians from 17 biggest greenhouse gas emitting (1) countries assembled in Washington DC for the climate talks under the ‘Major Economies Forum’ (MEF), they couldn’t have missed a couple of Greenpeace climbers dangling below a [...]
Hurricanes reduce ability of forests to store CO2
London, April 28 (ANI): In a new research, ecologists have determined that hurricanes can reduce the ability of forests to store carbon dioxide (CO2) and turn them into overall emitters of the toxic greenhouse gas.
According to a report in New Scientist, for the research, ecologist Jeffrey Chambers of Tulane University in New Orleans, Louisiana, and [...]
Fire an integral part of global climate change, say scientists
Washington, April 24 (ANI): In a new study, scientists have determined that fire must be accounted for as an integral part of global climate change.
The study identifies significant contributions of fire to climate change and identifies feedbacks between fire and climate change.
The researchers determined that intentional deforestation [...]
Ozone hole caused increased growth in Antarctic sea ice
Washington, April 22 (ANI): A new research has determined that increased growth in Antarctic sea ice during the past 30 years is a result of changing weather patterns caused by the ozone hole.
The research, done by scientists from British Antarctic Survey (BAS) and NASA, indicates that while there has been a dramatic loss of Arctic [...]
Cyclones can feed global warming by spurting ice into stratosphere
Washington, April 21 (ANI): Scientists at Harvard University, US, have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming.
The finding provides more evidence of the intertwining of severe weather and global warming by demonstrating a mechanism by which storms could drive climate change.
Many scientists now believe that global [...]
Scientists transform CO2 into clean-burning biofuel
Washington, April 17 (ANI): Scientists at Singapore’s Institute of Bioengineering and Nanotechnology (IBN) have become the first to transform the greenhouse gas carbon dioxide (CO2) into methanol, which is a widely used industrial feedstock and clean-burning biofuel.
The IBN researchers report that by [...]
Obama open to discussion about CO2 rules
WASHINGTON (Reuters) – U.S. President Barack Obama hopes to get a climate change bill on his desk this year and is open to discussing how stringent the rules of a carbon emissions trading system should be for industry, a top adviser said on Tuesday.
Nancy Sutley, chairwoman of the White House Council on Environmental Quality, said [...]
CO2 in underground water may bring carbon capture and storage a step closer
Washington, April 2 (ANI): A new research has shown that for millions of years carbon dioxide (CO2) has been stored safely and naturally in underground water in gas fields saturated with the greenhouse gas, a finding that brings carbon capture and storage a step closer.
Some models predict that CO2 would react with rock [...]
New tool differentiates between man-made and natural nitrogen-oxide pollution
Washington, March 26 (ANI): Scientists have used a new tool to differentiate between man-made and natural nitrogen oxide emissions.
Nitrogen oxides in the atmosphere, which are produced by lightning, biomass burning, and soil outgassing, [...]
Greenpeace says activists beaten during protest rally
Jakarta – Activists of the environmental pressure group Greenpeace were beaten by security guards while protesting against environmental destruction outside the headquarters of one of Indonesia’s largest palm oil companies Thursday, the group said.
Greenpeace accused the Sinar Mas Group, whose businesses include pulp, paper and palm oil, of destroying Indonesia’s forests with impunity through [...]
