Explain the last 10 years? Unstoppable Warming? Whoops...
Not arguing (yet), but please explain the question about the last 10 years. I must have missed something. I am not sure what the point is.
We have cooled in the last 10 years.
Ah, ok.
I have my own person opinions on this, and since we are sharing here is mine.
I really don’t follow this much. I did some quick searching on the 10 year thing. I think you could use the same evidence to argue the point both ways. Yes, there are and have been global climate trends and I think we can all agree on that. If you look at the data you can say that in general we have been in a warming trend. You can also say that the data in the past may not be accurate, so there has been no warming. Or then again it might be accurate. You can also say that the last 10 years have been in a cooling trend. You can say this is evidence that man is not the cause since our actions are pretty much unchanged. Or you can say that you can’t expect an increase year after year, that you might have some variations over a short period of time with 10 years not being a very large period of time.
My personal option is that many people mistake short term patterns with long term patterns. They mistake weather for climate. We had some hot summers recently. I cringe each time someone uses hot summer days to back up the idea of global warming.
I believe that what is happening now may very well be part of a climate pattern that is not man made. And that this pattern may be causing global warming (over many decades). And that this pattern may also have yearly or decade long up or down fluctuations. I also believe that there is evidence that what man is doing may be making this worse. That what we are seeing is not just one cause, but multiple causes of which man is one.
I really can’t think of a reason to not try to reduce our CO2 output if there is a possibility that this may be impacting the climate. I don’t think draconian measures are needed, but we can make reductions. I also don’t think we are going to know “who is right” within our lifetimes. So if we make CO2 reductions and it helps out then we did the right thing. If we make reductions and it doesn’t help, then did it hurt that much? I also believe that regardless of the cause, that it might be happening and that we we have to continue to adapt just has man has over many thousands of years.
The best analogy I can think up is the deforestation of Easter Island. The island once sustained large forests, but they declined over time. So much so that it is felt that it made it hard for the civilization that existed there to continue. I am sure someone was arguing that the trees would not last forever and that something should be done. And I am sure someone else was arguing that it wasn’t a problem. Or wasn’t a problem they could prevent. But at the time that they were arguing about the truth, it might not have hurt for them to put forestry practices into place just in case.
We have no idea how the forest disappeared. Maybe they did put forestry practices into place and was managing the number of trees and then maybe some huge natural disaster wiped them out anyhow. Or maybe they just cut them all down and then realized that the trend was in fact correct.
