When Perfikot encountered a research bottleneck, the first large-scale snowfall of the year silently arrived in the Northern Territory.
This caught many people by surprise, as when the snow fell, it still should have been deep autumn according to the Northern Territory's climate.
But for Perfikot and those aware of this doomsday disaster, the snowfall wasn't particularly surprising; on the contrary, they all felt a pressing urgency.
For the climate had already begun to collapse.
This isn't hard to understand, even though the global cooling has been persistently decreasing bit by bit, it is not a smooth linear decline.
Rather, it is a parabola, starting with a steady and gradual decline, leading to a cliff-like drop at the point of collapse.
Evidently, now is the time of the cliff-like drop.
With nine years of sustained cooling, the energy of the planet's surface atmosphere has gradually been depleted, and the original meteorological system has begun to collapse.
