Changes to land cover may enhance global warming in Amazon, reduce it in midlatitudes
New simulations of 21st-century climate show that human-produced changes in land cover could produce additional warming in the Amazon region comparable to that caused by greenhouse gases, while counteracting greenhouse warming by 25% to 50% in some midlatitude areas.   view more (2005-12-09)

Biofuels: More than just ethanol
As the United States looks to alternate fuel sources, ethanol has become one of the front runners. Farmers have begun planting corn in the hopes that its potential new use for corn will be a new income source.   view more (2007-04-06)

Climate change threatens a million species with extinction
Climate change may drive a quarter of land animals and plants extinct, according to a major new study published in the journal Nature - unless greenhouse gas emissions are drastically reduced. The largest collaboration of scientists ever to apply themselves to this problem studied six... view more (2004-01-07)

Financial sector, governments and business must act on climate change or face the consequences
Too few financial companies including banks, pension funds and insurance companies are taking the risks and opportunities posed by climate change seriously, members of the United Nations Environment Programme`s (UNEP) Finance Initiatives are warning. Losses as a result of natural disasters appear... view more (2002-10-08)

Adaptation to global climate change is an essential response to a warming planet
Temperatures are rising on Earth, which is heating up the debate over global warming and the future of our planet, but what may be needed most to combat global warming is a greater focus on adapting to our changing planet, says a team of science policy experts writing in this week's Nature magazine.   view more (2007-02-08)

Compact, wavelength-on-demand Quantum Cascade Laser chip offers ultra-sensitive chemical sensing
Engineers from Harvard University have demonstrated a highly versatile, compact and portable Quantum Cascade Laser sensor for the fast detection of a large number of chemicals, ranging from infinitesimal traces of gases to liquids, by broad tuning of the emission wavelength.   view more (2007-12-04)

Ancient Arctic water cycles are red flags to future global warming
Ancient plant life recovered in recent Arctic Ocean sampling cores shows that at the time of the last major global warming, humidity, precipitation levels and salinity of the ocean water altered drastically, along with the elevated temperatures and levels of greenhouse gases.   view more (2006-08-14)

Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today.   view more (2007-12-11)

Scientists reveal fate of Earth's oceans
Scientists at The University of Manchester have uncovered the first evidence of seawater deep inside the Earth shedding new light on the fate of the planet's oceans, according to research published in Nature.   view more (2006-05-11)

Beijing restrictions offer case study in emissions of key atmospheric gases
The Chinese government's restrictions on Beijing motorists during a three-day conference last November -- widely viewed as a dress rehearsal for efforts to slash smog and airborne pollutants during the 2008 Summer Olympic Games in Beijing -- succeeded in cutting the city's emissions of one... view more (2007-05-01)

Arctic ice meltdown continues with significantly reduced winter ice cover
As far as temperatures drop in the Arctic winter - on average to -34°C (-29°F) - a new study shows that in the last two years sea ice is shrinking on the surface of Arctic waters to record low levels.   view more (2006-09-14)

Field project seeks clues to climate change in remote atmospheric region
Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface.   view more (2008-06-13)

Confirmed - deforestation plays critical climate change role
Dr Pep Canadell, from the Global Carbon Project and CSIRO Marine and Atmospheric Research, says today in the journal Science that tropical deforestation releases 1.5 billion tonnes of carbon each year into the atmosphere.   view more (2007-05-14)

Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere.   view more (2006-02-24)

Explaining the methane mystery
Scientists have explained why atmospheric levels of the greenhouse gas methane have stabilised in recent years, but warn that increases could resume in the near future.   view more (2006-09-28)

Step on the gas — New fuel cell design adds control, reduces complexity
When Princeton University engineers want to increase the power output of their new fuel cell, they just give it a little more gas - hydrogen gas, to be exact.   view more (2007-01-17)

Europe’s environment satellite
Early in 2002 an Ariane-5 rocket will launch the largest and most advanced Earth observation satellite ever built in Europe from the European Spaceport at Kourou in French Guiana. From an altitude of 800 kilometres Envisat will deliver images and data that will help us better understand and more... view more (2001-11-09)

European lead in reading past climates from ice cores
Climate change is a reality today, but how can we find out about the future dangers it poses" What we really need is a full record of the Earth's climate for several hundred thousand years, complete with samples of air from different epochs that can be taken to the lab for analysis.   view more (2007-10-12)

North Pole's ancient past holds lessons for future global warming
Detailed information on greenhouse gasses and a subtropical heat wave at the North Pole 55 million years ago is providing information about the Earth's past as well as a portent for its future, according to reports in the June 1 issue of Nature.   view more (2006-06-01)

UN body asks Lund Researchers to investigate new type of carbon sink
Trade in emission rights is intended to reduce global emissions of greenhouse gases. Countries with natural carbon sinks—areas that absorb more carbon dioxide than they give off—can ‘trade off’ that resource in return for their commitments to reduce emissions. Thus far this... view more (2001-11-09)

Carnegie Mellon urges industry to broaden carbon footprint calculations
Carnegie Mellon University researchers are urging companies to embrace new methods for following the trail of dangerous carbon emissions that are responsible for much of the world's global warming threats.   view more (2008-08-18)

Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research.   view more (2006-12-06)

Safe Heating of Explosive Gases
The Institut für Mikrotechnik Mainz GmbH (IMM) has developed the micro structured gas heater MSGH for combustible or explosive media. A clear separation of the space containing the medium from the heating elements allows safe heating and overheating of process gases, gas mixtures or gas/vapour... view more (2004-06-23)
