375 mln people may face climate-related disasters annually by 2015

375 mln people may face climate-related disasters annually by 2015London, April 21: UK-based charity Oxfam has suggested that the umber of people hit by climate-related disasters is expected to rise by about 50 percent, to reach 375 million a year by 2015.

According to a report by BBC News, the Oxfam study says that current humanitarian systems would be unable to cope with the natural disasters.

It warns that agencies are in danger of being overwhelmed by events such as flooding, storms and drought.

Milky Way’s centre tastes like raspberries and smells of rum

Milky Way’s centre tastes like raspberries and smells of rumLondon, April 21: If a long term research by astronomers is anything to go by, then the centre of our of galaxy tastes like raspberries and smells of rum.

According to a report in the Guardian, astronomers searching for the building blocks of life in a giant dust cloud at the heart of the Milky Way have concluded that it contains the chemical ethyl formate, which gives raspberries their flavour and smells of rum.

‘Dancing’ algae can ‘waltz’ and ‘minuet’

‘Dancing’ algae can ‘waltz’ and ‘minuet’Washington, April 21 : Scientists at the Cambridge University, UK, have discovered that freshwater algae can form stable groupings in which they dance around each other, resembling forms like waltz and minuet.

The researchers studied the multicellular organism Volvox, which consists of approximately 1,000 cells arranged on the surface of a spherical matrix about half a millimetre in diameter.

Cyclones can feed global warming by spurting ice into stratosphere

Cyclones can feed global warming by spurting ice into stratosphereWashington, April 21 : Scientists at Harvard University, US, have found that tropical cyclones readily inject ice far into the stratosphere, possibly feeding global warming.

The finding provides more evidence of the intertwining of severe weather and global warming by demonstrating a mechanism by which storms could drive climate change.

Many scientists now believe that global warming, in turn, is likely to increase the severity of tropical cyclones.

Atmospheric engineering scheme to fight global warming could diminish solar power

Atmospheric engineering scheme to fight global warming could diminish solar powerWashington, April 20 : A new study has determined that a widely discussed "atmospheric engineering" scheme intended to combat global warming could have unanticipated consequences in reducing the effectiveness of certain kinds of solar power around the Earth.

In the study, the National Oceanographic and Atmospheric Administration's Daniel M. Murphy examines a proposal to minimize climate change by enhancing the stratospheric aerosol layer, which reduces sunlight to Earth by scattering it to outer space.
