Normal when it cycles back down, not when it continues to rise to unseen record highs like it has been for 50+ years.
Climate Change: Evidence
oh, dear gawd, CLIMATE CHANGE is NORMAL.
it has to change, otherwise we would be extinct already
Dumb ****, in the geological past, there have been many changes in climate. Some gradual, with the flora and fauna adapting over the space of time that the change took place in. Some, very rapid, with extinction events, with as much as 95% of the species, plant and animal, going extinct.
The present change, which we are creating, is among the most rapid to ever occur.
Abrupt Climate Change: Inevitable Surprises
Executive Summary
Recent scientific evidence shows that major and widespread climate changes have occurred with startling speed. For example, roughly half the north Atlantic warming since the last ice age was achieved in only a decade, and it was accompanied by significant climatic changes across most of the globe. Similar events, including local warmings as large as 16°C, occurred repeatedly during the slide into and climb out of the last ice age. Human civilizations arose after those extreme, global ice-age climate jumps. Severe droughts and other regional climate events during the current warm period have shown similar tendencies of abrupt onset and great persistence, often with adverse effects on societies.
Abrupt climate changes were especially common when the climate system was being forced to change most rapidly. Thus, greenhouse warming and other human alterations of the earth system may increase the possibility of large, abrupt, and unwelcome regional or global climatic events. The abrupt changes of the past are not fully explained yet, and climate models typically underestimate the size, speed, and extent of those changes. Hence, future abrupt changes cannot be predicted with confidence, and climate surprises are to be expected.
This summery was written in 2002, and we have seen since then how accurate it is. The reduction in Arctic Sea Ice, and resultant affects on the weather, that we are seeing now was not expected untill the last quarter of this century, not the first quarter.
