Did a scientist tell you this?  That is not how science works.  You cannot attribute events around you to some notion of obviousness.  That reasoning would not pass any physicist&#x27;s approval.<p>Climate science is predicated upon a proper understanding of physics.  Any scientist who tells you that worldwide evidence is obvious should be treated with the same level of respect as Dr. Oz.<p>The typical response would be that the physics is proven.  Well, AFAIK, yes, at least to the degree that CO2 is a greenhouse gas and that it has SOME effect on climate.  The magnitude of contribution to toal effect by various sources and sinks seems far from certain.<p>To draw a parallel, which a physicist (scientist) would do when instructing - this is like saying salt makes blood pressure go up, so it&#x27;s bad for you... And ignoring all the ways the body can come to equilibrium.  Stop eating salt, today, or you&#x27;ll burst.<p>So if a physicist calls it bullshit, that&#x27;s pretty much your trump card.  Which is why people put so much stock in Dysons opinion, because he was an expert in properly using the tools that most climate scientists are not experts in.<p>Were you to go study physics at a masters level for a bit, and then read scientific studies yourself with a critical eye, you&#x27;d learn how much of what we call science is grade A bullshit.<p>Until then, I&#x27;m afraid I&#x27;m not going to be able to debate with you.  It&#x27;s kind of like me arguing American football with John Madden.
