Cisco Systems CEO John Chambers is joining the virtual stage with Nobel laureate and former Vice President Al Gore on Wednesday morning to talk about climate change and technology innovation.

Chambers and Gore will use Cisco's telepresence system to communicate with a live audience at the VoiceCon trade show in in Orlando, Fla. They will discuss how unified communications technology, like the telepresence platform, can play a role in reducing carbon emissions, which are impacting climate change.
They'll also discuss other ideas for how businesses can reduce greenhouse gas emissions through innovative technologies and how the technology industry can create a sustainable model for addressing climate change.
The event will be Webcast live starting at 11 a.m. EDT/8 a.m. PDT. And anyone interested in tuning in can register at the Cisco Web site to sign up in advance.
My colleague Martin LaMonica, who covers green technology, will be listening to the Webcast. So look for a blog post from him later Wednesday.
