Thats the thing, isn't it? Climate is ALWAYS changing. Can you point me to a time in earths 4.5B year history when the climate wasn't changing?
If you looked into it you would have noticed how on the west side of Antarctica the icecaps are melting, while growing bigger than ever before on the east side.
In your examination of data, have you noticed how 6 of the 9 planets in our solar system have warmed up? Is that also man made? Perhaps some undiscovered species burning fossil fuels?
I know, the Maldives with average height of 3 feet above sea level are still there, and corporations as well as private individuals are still purchasing islands for resort developments for tens of millions of dollars. They're also investing in seaside property developments around the world, and banks, who examine risk before lending, are still funding these projects.
In regards to your 'house' and 'fire brigade' analogy. I agree, it would be good to get together for a conference about it, but that is not allowed is it? You cannot question/discuss climate change. The science is settled, remember? We must only act, act now! The same as you cannot question/discuss genders identities. You cannot question/discuss biological men competing in women sports. You must accept and obey without question.
