What observations do you offer that would encourage this other than claiming the last 3 years (2005 hottest) or last twelve (’98 hottest) equal global cooling when they are all among the hottest years in the last 2 million (a fundamentally flawed assertion that shows 100 % ignorance, or willful disregard, of basic scientific principles, namely that a three — twelve year period is not a long - term trend, but is variability until proven otherwise.)

The hydrologic cycle can change because of changes in plant cover — it's a common observation that after a forest fire or logging, streams and springs will flow higher and longer for a period of years.

So what we did with the model is: stretch the input of the carbon over longer and longer periods of time until we get a match between the observations and the carbon cycle and climate models.

Satellite observations may have resolved many of the spacial / temporal resolution issues surrounding proxy measurements of earlier periods there is a long way to go before we have sufficient data suitable for prediction.

«The question is again being discussed whether recent and long - continued observations do not point to the advent of a second glacial period, when the countries now basking in the fostering warmth of a tropical sun will ultimately give way to the perennial frost and snow of the polar regions.»

In fact, most uncertainties in the alarmist pseudo-science are internal contradictions and consequences of its shoddy practices: cherry picking data, making conclusions based on statistically insignificant observations, declaring trends based on variations that are within error margins, relying on computer models that contradict principles of the information theory, forging forecasts for unreasonably long time periods, etc..
