Is it, as James Lovelock claims, already too late to save humanity and the planet we rely on? We don't know, but there doesn't seem to be too solid a ground for confidence. Unfortunately, I missed David Attenborough's recent TV programme on the subject, but you can read his views here. Attenborough has remained as sceptical as possible for as long as he could, but now, he says, it is time to get "engaged".
It's probably not the kind of engagement Attenborough had in mind, but Stratfor.com's free weekly email intelligence reports said this week that Earth First! is promising to launch a radical campaign against climate change, taking direct action including the blocking of refineries and generally aiming to "make a lot of noise". Stratfor.com's analysts are sceptical that this will make much difference, but the seriousness of the problem certainly seems to demand, at the very least, noise.
Not least because New Scientist reports this week that climate change can even affect the "frequencies of earthquakes, volcanic eruptions and catastrophic sea-floor landslides". Unfortunately, this article isn't available on the website ...
Perhaps what we really need to wake people up to the dangers of climate change, says Marguerite Holloway in Scientific American, is a new Silent Spring, the 1962 book by Rachel Carson widely credited with launching the environmentalist movement. If Holloway is right, we could have found it in Field Notes from a Catastrophe by Elizabeth Kolbert. It could, she argues, be "this era's galvanising text."
