Well, yes, this issue is controversial because the consequences are in the future.
Sure a volcano can inject the same monstrous amount of CO2 we're injecting in the most "ambitious", uncontrolled experiment on the weather of our planet.
Besides, most of the people affected doesn't drive and do not have voice or vote on global affairs, like Pacific islanders and African people.
Even more: what's a few polar bears on the future of the planet? I happily concede flyn's point about the earth being practically indestructible, I've pointed people several times to
"Top ten ways to destroy the Earth"... Let me tell you it's not
simple to destroy the Earth. I quote:
You've seen the action movies where the bad guy threatens to destroy the Earth. You've heard people on the news claiming that the next nuclear war or cutting down rainforests or persisting in releasing hideous quantities of pollution into the atmosphere threatens to end the world.
Fools.
The Earth is built to last. It is a 4,550,000,000-year-old, 5,973,600,000,000,000,000,000-tonne ball of iron. It has taken more devastating asteroid hits in its lifetime than you've had hot dinners, and lo, it still orbits merrily. So my first piece of advice to you, dear would-be Earth-destroyer, is: do NOT think this will be easy.
I'm also missing Carlin's straight-to-the-point criticism and his catholic conscience (that I share), btw.
Sure the sun could dim itself by natural processes and drive us into an ice age, or conversely it could increment its output and fry all of us in the process. However, shouldn't we buy a few good parkas in the first case and some air conditioning in the second instead of dismissing those who warn us of the probabilities?
The fact that there is a controversy instead of decided action is what makes me doubt seriously that we, human race, qualify as intelligent beings. Even the humblest of bees has its food, housing and way of life guaranteed by the beehive, something humans are far from achieve. The way we're treating our environment shows our (me included) stupidity. It's easy to make jokes about the weatherman than taking an umbrella.

Here's good news: George W. Bush says that he is committed to fighting global warming. ... President Bush says he's really going to buckle down now and fight global warming. As a matter of fact, he announced today he's sending 20,000 troops to the sun" --David Letterman
"
According to a new U.N. report, the global warming outlook is much worse than originally predicted. Which is pretty bad when they originally predicted it would destroy the planet." --Jay Leno
"
The report on climate change said that humans are very likely making the planet warmer. To which Hillary Clinton said, 'Hey, can't blame me for that one.'" --Jay Leno
