Just some thought:

When I kill a guy its called murder, when I kill a million living its called genocide, when I kill myself its called suicide, when millions kill themselves its called ? And when million kill millions of people from unborn generations its called ?

We will need a whole new vocabulary to describe our current situation. That is what makes me think, does it make you think as well?

Greetings, Ed

the discussion about temperatres in the last 20,000 years avoids the real question. How did primates survive in the preceeding 1 to 4 million years? see

Jason – not sure how you come to that conclusion? (Note the x axis is logarithmic…)

I like this chart too but for a vastly different reason. I’ve been told over and over again, by people who seek to end debates with my by branding me a denier, that the change we’re experiencing has never before happened at such a rate. Yet any fool can plainly see it has. Great illustration to foster debate especially with those who don’t play the denier card.

Climate change, as evidenced by your graph, is something we will need to understand and adapt to, not something we can seek to prevent or change. Look at your own graph, even if, in the last 100 years, humans have negatively impacted climate cycles, would we be any less likely to see changes?

Joe, what’s the end date for that graph. Is it 2008?

If not, it would be handy to update it….who has control of it?

I think it would be a good idea to have a ‘one-stop shop’ for this kind of material. Are you planning to add more slides to this resource? In particular I would appreciate a slide of the Kyoto Cherry Tree Festival dates – I recall seeing a graph showing a startling change in the last couple of decades (of a 900+ year data run).

Joe -
This is a beautiful resource I somehow had missed, (having only used this site to view the
IPCC report WG1 in html format)
The information is sortable in three different ways.

Brewster – nothing wrong with preaching to the choir. It educates the choir who can then better proselytize to the wider world. I don’t think it’s entirely true that just the choir comes here any more than just the choir saw “Inconvenient Truth” or attend any in-person lectures. Joe’s blog is a great and growing resource for dealing with “sceptics super

Here is an outstanding graphic. Where is the debate. This clearly shows the delta of temp varying with that of CO2.

Can any confirm that this is accurate?
