Yours is a repost (paste) of the same bit that you offered up twice on the last climate thread. Other posters on that thread pointed out obvious errors and irrelevancies in your comments. Why the continued confidence?

Again, natural climate factors were responsible for historic climate change. But it should be seen as an obvious misstep in logic to assume that what is now happening has to be what had happened before. That same misstep of logic would lead to the assumption that all forest fires must now be naturally-caused, just as they were before humans.

There simply is no natural cycle or other natural factor that has been responsible for modern warming.
