You don't see extinction events like the one currently killing off the planet's coral reefs in natural cycles because the rising water temperatures are essentially starving them. Furthermore we can measure CO2 in stratum to across vast stretches of time to know how warm or cold the Earth gets in the course of those cycles. In comparing that to current temperature data and CO2 saturation we can know that the past century and the past forty years in particular are witness to an extraordinary warming event and that we, humanity, are likely the cause. --- Whatever happened to standards?
