Earth Hour in Malaysia (image from http://smksripermata.wordpress.com)
Hundreds of millions of people, businesses and governments around the world unite each year to support the largest environmental event in history – Earth Hour.
More than 5,200 cities and towns in 135 countries worldwide switched off their lights for Earth Hour 2011 alone, sending a powerful message for action on climate change. It also ushered in a new era with members going Beyond the Hour to commit to lasting action for the planet. Without a doubt, it’s shown how great things can be achieved when people come together for a common cause.
On Earth Hour hundreds of millions of people, organizations, corporations and governments will come together to make a bold statement about their concern for climate change by doing something quite simple—turning off their lights for one hour. Earth Hour symbolizes that by working together, each of us can have a positive impact in the fight against climate change, protecting our future and that of future generations.
Set Your Clock
On March 31st at 8:30 p.m. local time, Earth Hour will cascade around the globe—from time zone to time zone—uniting the planet under a single, simple, call to action.
How does climate change occur?
A continuous flow of energy from the sun heats the Earth. Naturally occurring gases in the atmosphere, known as greenhouse gases, trap this heat like a blanket, keeping the Earth at an average of 15 degrees Celsius – warm enough to sustain life. Carbon dioxide (CO2) is the most significant of these gases. The amount of naturally produced CO2 is almost perfectly balanced by the amount naturally removed through photosynthesis and its dissolution in oceans. However, the overuse of fossil fuels is leading to increased CO2 in the atmosphere, trapping more and more heat and warming the Earth.
As a result, we’re seeing more dramatic weather patterns across the globe. The effects of Earth’s changing weather not only causes devastating natural disasters but shrinking of the world’s ice shelves and glaciers due to warming sea water. Because ice acts as a solar reflector, the less ice there is, the less heat the Earth reflects.

Earth Hour has thus far been a success all over the world. Should have more days on Earth Hour to save our Mother Earth.
