Having lived in Australia for several years, and watched the weather change in both the UK and US I can't help but be aware that something is going on.

Too many people however are not even aware (despite documentaries like Al Gores "An Inconvenient Truth" ) that there is even a risk or reason to be concerned.

Luckily this July - 7/7/07 to be precise - MSN are presenting a series of concerts called Live Earth around the world (in the US, UK, Japan, Brazil, South Africa, China, Australia, and Turkey) to raise awareness of the problem.

To kick the process off, for the next 7 days a new song written and performed by Madonna exclusively for Live Earth is available for download from MSN so check out the site, find out where your closest concert is and check out the new track.

Then spread the word....
