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...

Climate change and timing of avian breeding and migration throughout Europe
Bird breeding and spring migration phenology have advanced in response to climate change, but the effects differ between sites. Here, we examine the geographical variation in laying- date trends in…
Recent Glacial Retreat and Its Impact on Hydrological Processes on the Tibetan Plateau, China, and Surrounding Regions
Glacial retreat on the Tibetan Plateau and surrounding regions is characteristic since the 1960s and has intensified in the past 10 yr. The magnitude of glacial retreat is relatively small…
Assessment of observed changes and responses in natural and managed systems
