Hi, I'm doing a bit of self-research before I form a strong opinion on my own: Climate Deniers are really annoying and tend to lack common sense, but scientists, despite most of them having good intentions, have been known to be wrong at times. What are the strengths of the argument that ENSO has caused this gigantic fluke of global warming/climate change versus the man-made argument. Because Correct me if I'm wrong, ENSO seems to be a seasonal effect while NASA's global warming chart (which depicts overall annual changes) from the late 1800's of the industrial revolution till now, seems to have skyrocketed.
