"What's not true is massive negative consequences having already happened, " Oh, yes they have; and they will get worse. "What particularly hasn't been established as being true is the combination of all the below points." 1 - "The earth has warmed, is warming, and will continue to warm." Established 2 - "This is overwhelmingly because of human emission of CO2 (and to a lesser extent other greenhouse gases)" established 3 - "Warming like this has never happened in human history" established "almost never in the planets history." Deccan Traps, Siberian Traps ... 4 - "If things are not massively changed the result will be globally catastrophic." yup 5 -" If human activity that produces greenhouse gasses is massively cut very soon. Then the crisis can be averted" Too late to avert, since it's upon us, but not too late to avoid making it worse. 6 - "Human greenhouse gas emissions can be rapidly cut, " FF-free by 2050 doesn't strike me as very rapid, and it's also something backward nations like the US won't be able to accomplish. "and over longer period nearly eliminated, in a cost effective way that doesn't amount to a global economic catastrophe. " 40 or 50 years; will only harm purveyors of fossil fuels.

I suppose it depends on what you mean by "massive". And your points are a mix of straw man arguments and mis-information. Your 1) is puzzling. Are you claiming there is little evidence of warming? Exactly how deeply is your head buried in your ass? Your 2) is false. While some of the warming is due to changes in insolation and other factors, it is indisputable that most of it is because of CO2 emissions. And, more importantly, it is the factor we actually have control of. The stance of "if we cannot control all factors, it isn't worth doing at all" is a bullshit argument. Your 3) is a mix of nonsense and bullshit. Not to mention the straw man. Our present period of warming does not have an equivalent in human history. Period. Full stop. At no point since we have been human have we experienced this rate of warming. There is no reason to believe otherwise. Now it may have occured at some point in the past prior to that, but we don't have that kind of granularity in the fossil record to determine that. Regardless, changes in CO2 concentrations and hence, temperatures of the degree we are experiencing do correlate strongly with mass extinctions, even over longer periods of time. Which are considered bad things. As to your 4), I suppose it depends on how you define "massively". If multi-meter rises in sea level and extinction of a large percentage of extant species is not a catastrophe, then what is? And 5). You keep using the word "massively". I don't think it means what you think it does. And so on.
