Carbon Footprints
The carbon footprint is a certificate that measure emissions are carbon dioxide (CO2) that are made in the production of goods, from raw material procurement to the treatment of waste, through the manufacturing and transport. Therefore CO2 footprint is the measure of the impact that human activities on the environment and is determined by the amount of greenhouse gases produced,...
Rising rivers set to wreck Bangladesh
Arguments over the causes of global warming will bring little succour to the people of Bangladesh. Flooding in the country is set to increase by up to 40 per cent this century as global temperatures rise, the latest climate models suggest. Each year, roughly a fifth of Bangladesh is flooded, and climate change is forecast to exacerbate the problem as sea levels rise, monsoons become...
Scientists Warn Of Western Drought
ECHO SUMMIT, Calif. — Frank Gehrke skied out on an unseasonably warm March day to take the final Sierra Nevada snowpack measurements of the season near this mountain pass south of Lake Tahoe — only to be stopped short by a muddy meadow where usually there would be deep snow. Something is happening to the snowpack, according to measurements Gehrke has collected...
A new Ice Age? None soon, says study
Evidence from the oldest layers of Antarctic ice ever collected suggests that the earth is not even halfway through the current warm era NEW YORK – Despite the recent trend towards global warming, scientists have long wondered whether the earth is nearing another Ice Age, an end to the 12,000-year temperate spell in which civilisations arose. Some have said such a transition...
Asian farmers sucking the continent dry
The world is on the verge of a water crisis as people fight over ever dwindling supplies, experts told the Stockholm Water Symposium. A generation ago, Indian farmers in the state of Gujarat used bullocks to lift water from shallow wells in leather buckets. Now they haul it from 300 metres below ground using electric pumps. But that technological revolution is about to have devastating...

The physical concept of climate forcing
Since the beginning of the debate on global climate change, scientists, economists, and policy makers alike have been using ‘climate forcing’ as a convenient measure for evaluating climate change. Researchers…
Ice Shelves Disappearing on Antarctic Peninsula
Ice shelves are retreating in the southern section of the Antarctic Peninsula due to climate change. This could result in glacier retreat and sea-level rise if warming continues, threatening coastal…
Potential effects of global warming on the biota of the Australian Alps
This initial report summarises current knowledge of predicted climate change effects on alpine and subalpine biota, with a focus on Kosciuszko National Park in south-eastern NSW. It outlines some possible…
‘Building a Future for Wildlife’? Evaluating the contribution of the world zoo and aquarium community to in situ conservation
In light of the United Nations declaring 2010 as the ‘International Year of Biodiversity’, we carried out an audit of in situ conservation projects supported by the world zoo and…
Morphological and compositional changes in the skeletons of new coral recruits reared in acidified seawater: Insights into the biomineralization response to ocean acidification
We reared primary polyps (new recruits) of the common Atlantic golf ball coral Favia fragum for 8 days at 25°C in seawater with aragonite saturation states ranging from ambient (Ω…
Low-energy sodium hydroxide recovery for CO2 capture from atmospheric air— Thermodynamic analysis
To reduce the risks of climate change, atmospheric concentrations of greenhouse gases must be lowered. Direct capture of CO2 from ambient air, “aircapture”, might be one of the few methods…
The Coral Reef Crisis: scientific justification for critical CO2 threshold levels of < 350ppm
On the 6th July, 2009, the Royal Society, the Zoological Society of London and the International Programme on the State of the Ocean facilitated a Coral Reef Crisis meeting to…
Melting permafrost could trigger ‘unstoppable’ climate change
By Louise Gray Melting Arctic permafrost could trigger “unstoppable climate change” as it releases ever increasing levels of methane gas, scientists have warned. A range of studies have found that …
Major bleaching events can lead to increased thermal tolerance in corals
Climate change is a major threat to coral reef ecosystems worldwide. A key determinant of the fate of reef corals in a warming climate is their capacity to tolerate increasing…
Global mapping of ecosystem services and conservation priorities
Global efforts to conserve biodiversity have the potential to deliver economic benefits to people (i.e., “ecosystem services”). However, regions for which conservation benefits both biodiversity and ecosystem services cannot be…
