Let's just make it the ambiguous question thread.
natural disasters are caused by climate change
bottles are black.
cancer is caused by cigarette smoking.
Three similar phrases. All ambiguous. All can be answered yes or no depending on context.
The point is individual cases cant be definitively attributed to a specific causal driver.
Even in the case of lung cancer for a long term smoker. A person that has been smoking for many decades may well have contracted lung cancer anyway if they didn't smoke. All the doctor can advise is that its MOST LIKELY that your lung cancer was caused by your smoking.
What gives us a clearer picture is looking at the cancer rate in a large sample of smokers and comparing that rate with a control and a sample of people who don't smoke at all.
There are effects however, driven by the warming of the planet that don't involve individual events such as rising sea levels or coral reef disappearance etc.
Like Sagan once said "extraordinary claims require extraordinary evidence"
And the global scientific community has reached a point in the AGW journey whereby the AGW denialist stance requires extraordinary evidence and rationale to maintain
For a person to even be uncommitted on the human drivers of Global warming is rather silly IMO. (although I can understand those that don't care)
