Scientists have been following ozone depletion for decades. Over the years, about 70% decrease in the ozone column has been observed in the southern hemispheric spring over Antarctica and according to recent reports, it is still continuing....

The Earth naturally absorbs incoming solar radiation and emits thermal radiation back into space. Some of the thermal radiation is trapped by certain so called greenhouse gases in the atmosphere. In recent years, carbon dioxide (CO2),...

The environmental damage caused by rich nations disproportionately impacts poor nations and costs them more than their combined foreign debt, according to a first-ever global accounting of the dollar costs of countries’ ecological...

The ozone hole over the Antarctic is the smallest in the last 5 years! At 25 million square kilometers, though it is still very large, the fact that it is shrinking is reason to feel positive. Dr Paul Fraser from Australia’s...

Greenhouse gases or HCFCs are used in air conditioning, refrigeration, fire-fighting foam and hairsprays. These gases raise the Earth’s temperature and lead to the thinning of the ozone layer. Ozone filters ultraviolet radiation, which is...

Be it smog, acid rain or CFC’s, air pollution or ozone depletion in the stratosphere, air pollution has long been threatening both human health as well as the ecosystems of our planet. Though one can have an excuse of survival by exploiting...

In the past 20 years, the ozone loss in the Antarctic has been ‘massive’. Compared to the same phenomenon in the Arctic, a new study ahs found that the loss in the Antarctic has been dramatic! It all happened in the heart of...

Ocean’s food supply can get dramatically affected by ozone depletion’s long-term impacts. This is suggested by a new research in Antarctica. Phytoplankton is a major food source of lower species, like krill. A Tasmanian scientist-group...
