Sentences with phrase «chaotic changes occurring»

Not exact matches

The fact that there has on any basis been little further warming over the course of the last 10 to 15 years over and above that which had already occured by the mid / late 19902 suggests that recent extreme weather events are not the consequence of additional warming (there having been all but none these past 15 years) and therefore must be due to natural variability of weather events in an ever changing and chaotic world in which we live.

I always believed that the oceans were an important element in localised weather conditions over the short term but feel that relatively sudden shifts in climate occur through external forcings such as volcanic eruptions, meteor strike and the effects of changes in cosmic rays and sun spot activity, which are, unfortunately, all chaotic by nature and unpredictable.

It is true that the model replications of past conditions are not perfect, which is to be expected given the chaotic variations of the climate about its now - changing baseline; however, the ensemble of model simulations has been tested against previously observed perturbations to climate (such as the response to volcanic eruptions) and overall they correspond well with what is observed to occur.

And indeed, the chaotic element implies that small changes, say in greenhouse gases, can result in nonlinear changes in outcomes — including very cold conditions that can and have occurred in a matter of months to decades.
