Warning signs

Warning signs of climate change - İt was on Christmas day 1983 that Smith first noticed that something weird is happening. When they were going to the church is was raining in İnuvik a town in north of the Arctic Circle, at a time when it was suppose to be some 30 degrees below zero. None of elders had any memory of such mild weather in winter. Nowhere else on the planet is the current warning tread more pronounced than in the Arctic, and nowhere else does it seem to leave a deeper mark. The Arctic is changing extremely abruptly on a geological time scale. There even might be a good side to the story, less ice during the Arctic summer night open new shipping channels and oil and gas regions could open up for instance and local hunters could get around by boat more easily!!! Arctic is the early warning system for Climate Change.

Control without hierarchy - We should expect a general theory of complex systems to emerge but it is clear we dont have one yet. Studying natural systems operational functions without central control will reveal whether such systems share general properties. Understanding complexity, self organization, and synergies - when the whole is greater than the sum of its parts - have emerged as alternatives for metaphors of control. But these terms are used merely where we cannot explain phenomenons. İn physics, we notice dissatisfaction with linear definitions such as
that a particle's behaviour is caused by the equivalence of two terms in an equation.
