One should also realize that _all_ man-made CO2 emissions add up to only a tiny percentage of total CO2 production. Even if _all_ human CO2 production ceased this very instant (including respiration, if you want to go so far as the kooks who think the only way to "save the planet" is voluntary extinction of the human species -- there's a couple of web sites on the subject), it's possible that CO2 levels would still be climbing. Increased CO2 _might_ be a result of warming, not a cause. We simply don't know enough yet. It appears from some studies that on a geologic time scale, CO2 levels are currently rising from an _all-time low_ over the past couple of million years (the Ice Ages may be related). > >If the US doesn't support it and Japan doesn't either then Kyoto is a dead > >duck.

Although when energy usage (and pollution created) is compared with GDP, the US is one of the most efficient nations on Earth. It's the Third World where things are getting dire. Poor people can't _afford_ to worry overly much about the environment, and it shows. > >The recent train of thought is that we have 40 to 100 years before the > (tale of woe deleted) > > No one is really sure what will happen.

Yes, it's a demonstrable fact that climate has changed more (sometimes in a few decades, maybe only a couple decades) in the far past (in human terms, not geologic) than even the most dire current predictions of global warming forecast over the next century. I have no doubt at all that had the professional Chicken Littles of the world would also have been carrying on just as loudly if they'd lived 12,000 years ago as the current Great Warming began. Of course, the disasters that befell the world (the larger part of the icecaps melting off, sea level rising 100 meters, etc) led directly to what we consider "normal". Warming is happening now, but whether or not humans have _appreciably_ influenced it is an open question. What caused the Little Ice Age of the 1600-1800's? And what brought it to an end? I think solar variability has _much_ more impact than human activity has had, and one really good volcanic eruption like Tambora, Thera, or the truly monstrous one of Krakatoa in the far past that split Java from Sumatra would make the sum total of human influence look puny indeed. > The problem is that we don't really understand the global environmental system > yet.

Luckily, we're _not_ staying the course (not on a decadal scale). Technology is improving rapidly, and in the industrialized world, things are mostly getting better. Some "improvements" are just lying with statistics, but then so are _some_ of the "dire" events that get highly publicized. I've read that Germany's claimed reduction in greenhouse emissions since 1990 is only real when all of current Germany is used as the basis for comparison. The western part actually went up slightly, while the economic collapse of the dirty, inefficient heavy industry in the old eastern part is what brought the sum total down. Larry
