On March 31, 2007 for one hour, one city made the bold move and powerful statement about the urgent need to take action on the global warming.


Today, Saturday March 28 at 8:30 pm in each time zone, millions of people in thousands of cities are expected to turn off the lights for one hour to raise people’s consciousness about the link between global warming and energy use.


Started in Australia two years ago and started as one city’s commitment to change the world, has now become a global commitment.


The goal for this year is to get 1 Billion people to turn their lights off for an hour.  In 2007, 2.2 Million homes and businesses switched off their lights and in 2008, it went up to 50 Million all over the world.


The whole point of Earth Hour is to cast a vote for Earth and against Global warming.  Make a visible statement of our commitment as Earth’s inhabitants and caretaker.  This move and vote for our mother Earth will be done by just turning our lights off for an hour.  But its worth is few watts from each home and the impact of savings along the way and energy in our lives.


Perhaps we can even participate more by unplugging our home appliances as well to make more resulting impact.  I have participated on this movement since last year and plan to be more active in the coming years.


If you are still not convinced, I am conveniently sharing you with some of the effects that our Earth is suffering from.  All of these are lifted from the National Geographic Channel’s website.  To learn more on the effects and causes, visit this site.  Read on:


And the effects of rising temperatures aren’t waiting for some far-flung future. They’re happening right now. Signs are appearing all over, and some of them are surprising. The heat is not only melting glaciers and sea ice; it’s also shifting precipitation patterns and setting animals on the move.

Some impacts from increasing temperatures are already happening.

  • Ice is melting worldwide, especially at the Earth’s poles. This includes mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice.
  • Researcher Bill Fraser has tracked the decline of the Adélie penguins on Antarctica, where their numbers have fallen from 32,000 breeding pairs to 11,000 in 30 years.
  • Sea level rise became faster over the last century.
  • Some butterflies, foxes, and alpine plants have moved farther north or to higher, cooler areas.
  • Precipitation (rain and snowfall) has increased across the globe, on average.
  • Spruce bark beetles have boomed in Alaska thanks to 20 years of warm summers. The insects have chewed up 4 million acres of spruce trees.
