Why the increasing temperature would cause extinctions?
Pleistocene-Holocene extinction
Normally we have talked about five extinctions. But now the number of extinctions is six because at the end of the last ice-age was the extinction of the giant animals(1). If we want to prepare the threat, we must know and realize threats. And we must not underestimate the threat. The thing is that we should find a solution to the worst problem, and that is climate chancing. Some researchers have said that climate warming has destroyed species in the case of all extinctions or at least the worst of them(2). The sixth mass extinction of our planet (3). In that extinction, many mammals like Mammoths were destroyed for some reason.
The tale is about the Holocene-period extinction, but the same model can maybe be caused also the destruction of dinosaurs. Maybe Mammoths were mammals, but they would need internal fat as well as the dinosaurs, and if the temperature would rise for a long time, the behavior of animals would change. And then they would not collect internal fat for winter, and then suddenly something drops the temperature.
At the end of the final ice-age, the reason for extinction was the fast rise and drop of the temperature. When the long warming period stopped suddenly and the temperature started to move fast up and down that thing caused a more dangerous situation than some warming or freezing alone.
The similar effect can kill dinosaurs
There is a possibility that climate warming, what had continued a long time would increase the effect of the nuclear winter after the volcanic eruption, which might be connected with the asteroid impact. When the asteroid has impacted the Earth, that thing happened at the worst possible place.
One of those bites dropped on the Yucatan peninsula, but some other bites would be impacted the water. That kind of thing can cause the worst tsunami ever, and if that asteroid has been crushed to smaller bites that can explain the large area of the effect of the impact.
Some of those bites might be the cosmic snowballs, what have exploded on air, and some of them would cause the impact wave, which travels in the magma layer. That thing caused volcanic eruptions all around the world.
How meteorite what impact on the ground can cause a volcanic eruption at the other side of the planet?
When the meteorite impacted the ground, that caused the fast decrease of temperature. And if dinosaurs were not prepared by collecting fat in their bodies, that kind of thing can be devastating
The cosmic snowball would explain the reason, why that meteorite was not left the impact crater on the Earth. Or by the way, The Gulf of Mexico might be the result of the meteorite impact but is that the meteorite, what caused the extinction of the dinosaurs. When cosmic snowball hits the lithosphere, the impact energy would be transmitted to the magma and continues to travel to the other side of the Earth. And then the magma would be pressed out from the volcanoes.
But if the climate has been warm a long time the dinosaurs and vegetables would be adapted to the warm weather. Then the steam along with ash, what rise out from volcanoes and burning forests and grasses caused the nuclear winter, where the temperature suddenly dropped, and the dinosaurs froze to death. The effect of nuclear winter was so devastating because the dinosaurs were not collect fat to their bodies, and that caused death. Of course, the tsunami and fire that were caused by that meteorite were devastating.
