I find it ironic that the same people who will deny climate change without absolutely certain proof will use as an argument the statement “The earth will end only when God declares its time to be over.” For the first part they need absolute proof while for the second part they believe and accept without any proof whatsoever. They will be happy to tell you that you should join their religion just in case there is a God but will not use the same reasoning about climate change.
