Actually, geologists have acknowledged this possibility for a long time. 

  Certain catastrophic events can cause immediate, though usually 

temporary, climatic changes.  These events include glacial-outburst 

floods, volcanic eruptions, meteor impacts, ice-shelf breakups, and 

submarine landslides.   The climate is fairly delicately balanced 

between the atmospheric and oceanic circulation systems, and if you 

affect one of these, a disturbance develops that can drive a region 

warmer, cooler, wetter or drier.  This can happen at a variety of 

scales, all the way up to global, and the feedback mechanisms can 

restabilize it either back to the same as before or to a different 

climatic regime.



In today's world, we have to assume that any climate change is bad. 

Crops are planned based on water availability and growing season length. 

  A repeat of the Little Ice Age would have a huge economic impact in 

the northern latitudes (imagine even two consecutive years of regional 

crop failures), while significant sea level rise (several inches) due to 

global warming would cause untoward harm to coastal communities and 

countries such as Holland.  Many parts of the world have large 

populations that are already overstressing limited agricultural and 

ecological resources.



I think we politicize climate studies at our peril.  This is one area 

where the knowledge and predictive ability can help us mitigate 

disaster, no matter if the cause of climate change is natural or man-made.



My own opinion,
