Climate change threatens world iconic ecosystems
Posted by Zee News: None Given on March 22nd, 2015
Zee News: Without better local management, world's most iconic ecosystems are at risk of collapse under climate change, warn researchers.
Protecting places of global environmental importance such as the Great Barrier Reef and the Amazon rainforest from climate change will require reducing pressures like over-fishing, fertiliser pollution and land clearing, they said.
Writing in the journal Science, an international team of researchers warned that localised issues, such as declining water quality from...

Climate change hamper world food production: Scientists
Posted by Zee News: None Given on February 16th, 2015
Zee News: The acceleration climate change and its impact on agricultural production means that profound societal changes will be needed in coming decades to feed the world's growing population, researchers at an annual science conference said.
According to scientists, food production will have to be doubled over the next 35 years to feed a global population of nine billion people in 2050, compared with seven billion today.
Feeding the world "is going to take some changes in terms of minimising climate...
North India among climate change impact hotspots: Study
Posted by Zee News: None Given on July 4th, 2013
Zee News: A new study by an international team of researchers has suggested that north India is among the few regions identified as ‘hotspots’ vulnerable to extreme climate changes, which in turn could lead to a fall in agricultural production and severe ecosystem changes.
The study, based on the computer simulations of future climate scenarios, was conducted by the international researchers from Germany and was published in the US journal Proceedings of the National Academy of Sciences.
While the climate...
Climate change may lead to failure of Indian monsoons
Posted by Zee News: None Given on November 6th, 2012
Zee News: Global warming caused by extensive human interference in the environment will likely result in failure of Indian monsoon in the next 200 years threatening food supplies, a new study has warned.
The study suggests that increased human activity like burning of fossil fuels and related shifts in tropical air flows, which has lead to drastic climate change, could result in collapse of monsoon rains about every fifth year between 2150 and 2200.
India being an agrarian society entirely depends on...
Climate change precipitates food shortages, unrest
Posted by Zee News: None Given on February 2nd, 2012
Zee News: Long-term climate change has often destabilized civilizations through food shortages, hunger, infectious disease and unrest, a study reveals.
Historical records foreshadow a grim picture for a future threatened by even greater climate change, says the study by the Australian National University (ANU).
Tony McMichael, professor at the ANU National Centre for Epidemiology and population Health, examined climate change and its impact over the last 6,000 to 7,000 years, as documented in historical,...
