Retrospective: Earth Day 2010

It's so beautiful out! But, Spring is a month early.

There was a radio show detailing some of the alternatives scientists have begun to discuss because no political solutions appear possible. The alternatives: bio-engineering to "cool" the earth, to counteract dangerous climate change.

There was some hope, when Obama was elected, that he would reverse US opposition to action to slow climate change. After all, the US was global polluter par none until last year (when China surpassed us). Also, the case that global warming is happening and that humans are largely causing it keeps on getting stronger, despite DC's "snowmageddon."

Further, that we are getting nearer and nearer to major climate tipping points. We may already have surpassed some: for example, massive releases of methane as Arctic permafrost thaws (methane is 25 times more potent than CO2 as an agent promoting global warming). All the predictions of even two years ago have proven too low; the high range forecasts (faster global warming) appear to be the low-range of what has already occurred.

Yet, the meeting on climate change in Copenhagen, in which the US was supposed to lead the world in a global response, was an abject failure. It was in large part because Obama offered only the limp-wristed cap and trade and low-ball cut to emissions that has apparently foundered in the stalemated US Congress. Republicans and corporate Democrats reject even that inadequate response.

So, what to do? Bio-engineering? Will the US unilaterally spray the atmosphere with various additives to make clouds more opaque, or to reduce ocean reflectivity, or…?

If not the US, then who? Russia? China?

Put this way, perhaps you can see the problem: if we can't agree on reducing CO2 emissions, how on earth are humans going to agree on something that is still highly speculative, that might cool the earth, but might just screw up the climate even more?

Parenthetically, the scientist on the above-mentioned radio show let drop that 2 billion people depend on the monsoon rains in South and Southeast Asia. What would they do if the US unilaterally sprayed clouds and the result was that the monsoon rains failed? They'd have to leave, or starve! Two billion desperate people. Oh, and they have nuclear weapons: we're talking about India, Pakistan and southern China.

No wonder US intelligence rated the threat from global warming/climate change as greater than al Qaeda!

Perhaps humans are incapable of cooperating globally. Instead, oil and coal (and other) interests must safeguard profits: they have a lot of money to buy policy-makers: vested interests always do.

Perhaps this will be the epitaph of global civilization: vested interests trumped common sense.

We still have time to redeem Earth Day 2010, but not much time. Forget about the American Empire. We can't replace Ephesus with Constantinople as the Romans did. Some humans may survive, but it might be in caves.
