Global Warming

The addition of greenhouse gases (e.g. carbon dioxide, methane, ozone) in atmosphere increases the temperature of the Earth. These gases remain in the lowest part of Earth's atmosphere and do not allow solar radiations to reflect back into space. As a result, heat remains within the Earth's atmosphere and increases its temperature. This is called global warming.

1990

In 1990, the United Nations established Intergovernmental Panel on Climate Change (IPCC). It provides scientific advice to the world leaders on issues like the build-up of greenhouse gases and its prevention. According to IPCC, Earth's surface temperature has increased -0.2°C per decade in the past 30 years

The Maldives' Survival

Scientists fear that the sea level is rising up to 0.9cm a year. Rise in sea level has worst effects on coastal countries. Most of the islands of the Maldives are less than 1 metre above sea level. It is estimated that within 100 years, the Maldives might become uninhabitable and the citizens would be forced to evacuate,

Greenhouse Effect

The term Greenhouse Effect refers to the phenomenon in which certain gases (called greenhouse gases) trap hoat in the atmosphere. These gases act ke the glass in a greenhouse, which does not allow the inner heat so escape When sunlight reaches the surface of the Earth, much of ta energy is transformed into beat energy The Earth surface reflects this heat energy towards space as infrared radioton The greenhouse gases trap infrared radiation and and it back to Earth Cartion dicide,mathahe and nitrous oxide are important greenhouse gases Since 1800 the amount of Carbon dioxide in atmosphere has increased 30 % The amount of methane has more than doubled and the amount of nitrous oude has increased about 8%
