And how do you think they confirmed this event and the speed in which it impacted the environment? Sediment layers and tree ring fossils..... these events were measurable and could be tied to a cause. Other temperature changes were more gradual over a period of 100's of years.... we have exceeded this rate of "natural" temperature change and seen it occur in just 20-30 years. Why? Just as volcanoes or meterors did it quickly in the past we are accelarating the "natural" rate via CO2 and man made fossil fuel consumption.
