Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

and often mock the absurd screeches of doom that frequently circulate through the press. I have good reason for some - it is hearsay and speculation backed up all too often by zero amount of testable evidence. Comparisons to acid rain and dying forests, the ozone hole and so on are apt in that regard.

There is, however, one looming big difference.

Acid rain was addressed (although far from actually being solved).

The ozone hole was addressed and seems today to be stabilising.

The GHG, which at minimum intensify global warming and at maximum drive the whole process, are still not properly addressed, and total GHG concentration is still ramping up and accelerating. The doom scenarios ramp up accordingly.

It's chaos theory - and the longer the earth is exposed to it, the more erratic it can get - I do think that.

The level of linearity of the climate is a clear worrrying question.. pity is too technichal... most models should work fine thinking in decade terms ... if the models are correct...

The problem is that there might be some term we do not foresee or that the level of linearity breaks down sooner than expected and irrelevant forces became stronger..

Difficult to foresee... but the more we push the parameters (as the CO2 in the atmosphere..) the more changes we will find vey upleasant scenario..

that is why glboal warming will be either a grave phenomena or a catastrophe in 100 years... who knows?

A pleasure

Discontinuity in the dose-response relationship is a frequent phenomenon for many kinds of pollution. A typical example is the release of a toxic agent in a river. At low to moderate levels, an increase in concentration will cause a proportional increase in the mortality of fish. Beyond a certain threshold, however, there is a jump to a new state and nearly all fish die.

We might be reaching such a threshold for climate gases, as the earth system's capacity for taking up CO2 is diminishing. See this guardian article.

And, as I reported in a comment last week, some bozo in a Spanish morning radio debate was using the fact that the ozone hole was addressed to argue against the reality of global warming. "Weren't we supposed to have fried because of the ozone hole? And yet here we are!"

Pundits! Darn you all to Heck!
