|“between 1970 and 2010, emissions increased 79%, from 27 Gt of [greenhouse gases] to over 49 Gt [billion tons]. Business-as-usual would result in that rate continuing.” An increase of that rate to 2100 would result in 189 billion tons of greenhouse gases being emitted at the end of the century. |
=> this scenario is a possibility.
=> the climate denier's logic seems to be, a low probability scenario is just another very improbable scenario.
=> But when this low probability scenario, if it comes true, means the end of the world, then it should be taken differently, not as just another improbable scenario.
=> If you are a gambler with some money at stake, then you can discount such an improbable scenario. But that improbable scenario is about the end of the world, then it is not just another possibility among the many and more probable ones. You work to eliminate or minimize the chances no matter what the cost.
=> 'business as usual' is a highly probable scenario, especially with Donald Trump running the USA and with the rise of nationalists around the world. Business as usual is the 'most probable' scenario.
