From the outset, we wanted Green Options to be a space where people talk to one another about the green topics that matter to them. While we set the agenda here on the blog, and in other portions of the site, our Discussion Forum is the place where you decide what needs addressing. If you haven't visited the Forum, drop in, and strike up a conversation…or join one.

As Ryan and Jimmy showed Tuesday, there's still plenty to discuss regarding the topic of climate change. While I'd guess that most of the team members here at GO fall into the 90% of people who've accepted the findings of the Intergovernmental Panel on Climate Change and other scientific bodies regarding the role CO2 emissions play in the climate crisis, there's still much to discuss and debate about the action we need to take. Economics tend to be at the core of most discussions about large-scale action, and conversations about the costs and opportunities created by environmental challenges need to occur within the public and private sectors, as well as among informed and concerned citizens.

Some other fodder for discussion:

• The human costs: Climate change is definitely an environmental justice issue, particularly since the developing world will likely "feel the heat" the most.
• The broader ecological costs: We've all read and heard about the polar bears. What other implications does action (or inaction) on climate change hold for other environmental challenges?
• The "marketing" angle: A recent post at The Oil Drum addresses the long-term consequences of climate change in light of research that shows we human beings tend to be very short-term in our thinking. Marketing guru Seth Godin noted last year that "global warming" is an ineffective phrase from a marketing standpoint. How do we communicate the threat of climate change without resorting to "chicken little" tactics?

Clearly, I've just touched the tip of the iceberg (a fitting metaphor, no doubt!). Got something to say about climate change? Say it in the Forum…
