We are pretty preoccupied with climate change on this planet these days. This week the Climate Week is taking place in New York City, partly preparing for the big Copenhagen meeting in December where we hope to get the replacement of the Kyoto Agreement in place. (I said HOPE).
I always say I do not discriminate against any of the planets including planet Earth. NASA must have the same philosophy. Look at this awesome study of the changing climate of Mars all revealed by laser techniques. :-)

The media will be packed with climate change articles and opinions as we get closer to the Copenhagen meeting in December. I'll be contributing to the discourse, too. This is one fresh article written about the ongoing work by among others the Stockholm Environment Institute.
I do believe China is capable of leap-frogging the western worlds polluting history. It is a question of international politics to make that actually happen...

I've collected a whole bunch of the new Hubble images. I simply couldn't help myself. They are gorgeous. And there is a quasar among the new products. I have an extremely weak spot for quasars. :-)
