CANCUN (Mexico): A UN conference on Saturday adopted a modest climate deal creating a fund to help the developing world go green, though it deferred for another year the tough work of carving out
deeper reductions in carbon emissions causing Earth to steadily warm.
UN Secretary General Ban Ki-moon said that the global talks on climate were an “important success” but that new efforts are still required.
The accord establishes a multibillion dollar annual Green Climate Fund to help developing countries cope with climate change, though it doesn’t say how the fund’s money is to be raised. Last year in Copenhagen governments agreed to mobilise $100 billion a year for developing countries, starting in 2020, much of which will be handled by the fund.
Mexican President Felipe Calderon, in a speech, declared the conference “a thoroughgoing success.”

Islamabad, the capital, is perpetually smothered by a thick cloud of smog that hides views of the Margalla Hills that tower over the city's tree-lined streets.
Water covers over 70% of the Earth's surface and is a very important resource for people and the environment. Water pollution affects drinking water, rivers, lakes and oceans all over the world. This consequently harms human health and the natural environment.
Now that you know how nature treats water, let's see how it's done in the water plant before we consume it in a glass of water.
Water treatment in a typical water treatment plant is shown in the picture below. Based on the characteristics of the raw water and on other factors, this treatment process may vary considerably from place to place. Read More
