If Global Warming Doesn’t Kill Us, ET Will
Jon Huntsman tweeted yesterday:
To be clear. I believe in evolution and trust scientists on global warming. Call me crazy.
Um. These scientists you trust, some of them at least, are accused of data manipulation and standing the peer-review process on its head. Call me crazy, but I don’t trust them.
In related news, The Guardian brings us:
The referenced scientists are a meteorologist and a geographer from Penn State and another researcher from NASA’s Planetary Science Division. Their paper (.pdf link) is a “scenario analysis” of what might happen should the Earth experience an encounter with an Extra-Terrestrial Intelligence (ETI). Among their conclusions:
Another recommendation is that humanity should avoid giving off the appearance of being a rapidly expansive civilization. If an ETI perceives humanity as such, then it may be inclined to attempt a preemptive strike against us so as to prevent us from growing into a threat to the ETI or others in the galaxy. Similarly, ecosystem-valuing universalist ETI may observe humanity’s ecological destructive tendencies and wipe humanity out in order to preserve the Earth system as a whole. These scenarios give us reason to limit our growth and reduce our impact on global ecosystems. It would be particularly important for us to limit our emissions of greenhouse gases, since atmospheric composition can be observed from other planets. …
Suppose we say that an alien civilization has been observing our planet’s atmosphere over the last 50 years. The concentration of carbon dioxide in the atmosphere has increased from 0.032% to 0.038% in that time; would a highly advanced alien intelligence see that as an existential threat to the Universe?
Our scientists are alarmed. Our politicians are alarmed. If we let them have their way, I am certain their designs on controlling greenhouse gases will destroy us.
Thanks, but I’d rather take my chances with the aliens.
