Further doubts atmospheric umbrella will save marine environments

By - June 18, 2009
We recently looked at problems with a last resort solution to counteract global warming by artificially shading the Earth from sunlight by injecting sulphur or small, reflective particles into the upper atmosphere. Now a new study from the Carnegie Institution has thrown further doubt on the effectiveness of such a proposal. Although it may lower the planet’s temperature by a couple of degrees, it would do little to stop the acidification of the world’s oceans that threatens coral reefs and other marine life. Read More

Playing roulette with the climate – everybody loses

By - May 22, 2009 2 Pictures
Research carried out by the MIT's Center for Global Change Science has predicted that global warming will be roughly double previous estimates – and could be even worse than that. While a major 2003 study indicated a median projected increase in earth surface warming of 2.4 degrees Celsius, the new study, which takes into account possible changes in human activities, points to a median probability of surface warming of 5.2 degrees Celsius by 2100 unless drastic action is taken.

Ground-breaking research finds way to convert CO2 into clean-burning biofuel

By - April 19, 2009
Scientists at the Singapore-based Institute of Bioengineering and Nanotechnology (IBN) have made an unprecedented breakthrough in transforming carbon dioxide, a common greenhouse gas, into methanol, a widely used form of industrial feedstock and clean-burning biofuel. Using "organocatalysts", researchers activated carbon dioxide in a mild and non-toxic process to produce the more useful chemical compound. Read More

New climate model predicts almost ice-free Arctic Ocean in just 30 years

By - April 8, 2009
According to new research the Arctic Ocean may be ice free in the summer months much faster than previously estimated. Research based on earlier climatic models suggested that this would not occur until the end of the century, but new models suggest that the Arctic might lose most of its ice cover in as little as 30 years - three times more rapid than previous studies have indicated. If this was to occur, the amount of the arctic covered by ice at the end of the summer could be down to around 1 million square kilometers (390 000 square miles) compared with the currently coverage of 4.6 million square kilometers (1.8 million square miles).

Did salt lakes kill the dinosaurs? And will they kill us?

By - April 2, 2009 2 Pictures
A new report by an international team of scientists has suggested that the largest mass extinction in the history of the earth may not have been caused by volcanic eruptions, methane hydrate or the impact of an asteroid as previously surmised. It may actually have been triggered by giant salt lakes, whose emissions of halogenated gases changed the atmospheric composition to such an extent that vegetation was irretrievably damaged. While this is a lot less dramatic than a volcanic eruption or an asteroid, the effect would be no less devastating and may have implications for us today with forecasts predicting an increase in the surface areas of deserts and salt lakes due to climate change that researchers expect will also lead to an increase in the effects of these halogenated gases.

Climate Change Belief Research - great cause for concern

By - March 25, 2009
It just goes to show you what a bad state the education system is in when just 51% of the population believe that climate change is caused by human activities. Opinion Research Corporation surveyed 1,000 people in late January and found that 29% believe climate change is occurring naturally, 15% believe climate change needs to be proven scientifically either way and 3% believe climate change doesn’t exist. Oh, and for the record, of those who got it right, 55% were male, which means ... we're no longer sure whether to be more concerned about global warming or global ignorance. Read More

Vertical farming with seawater

By - March 24, 2009 7 Pictures
The saying used to go, ‘only in America’, but in recent years it might be truer to say, ‘only in Dubai’, especially when it comes to architectural wonders. Buildings that would be unfeasible just about anywhere else seem to regularly spring from the ground in the oil rich emirate. The next eye-popping construction to grace the skyline could be a seawater vertical farm that uses seawater to cool and humidify greenhouses and to convert sufficient humidity back in to fresh water to irrigate the crops.

Naturally occurring bacteria converts CO2 into calcium carbonate

By - February 23, 2009
Expensive carbon capture and storage (CCS) projects are gaining momentum around the world as a way to combat greenhouse gas emissions (or is that sweep them under the carpet?), India’s Economic Times has reported that a team of Indian scientists have discovered a naturally occurring bacteria that could help fight global warming by converting CO2 into calcium carbonate (CaCO3) - a common compound found as rock all the world over.
