What would most likely trigger a climate change that could lead into a mass extinction?
There are a lot of reasons. One is a big cloud (like one resulting from massive volcanic activity or the impact of a large asteroid) can block the Sun and plants would not s…urvive, so then many herbivores die followed by most carnivores. When an environment changes the organisms living in it may not have the time to evolve to adapt, and so they die. A change in climate can lead to extinction because it can destroy organisms' habitats. For example, woolly mammoths had thick fur that was perfect for keeping themselves warm in the cold area. When global warming caused the climate to become warmer, their traits for cold weather were no longer helpful and eventually became extinct.
It's happening right now. The human race has or is about to wipe out as many species as the meteorite that hit the planet 65 million years ago and ended the reign of the dinos…aurs, which was about 90% of all life on earth.
The Permian-Triassic Extinction
id say all the rain forest being burned down or CUT down. it makes me sad to see that many people dont care about all these animals....
Typically, cold-blooded animals are more likely to survive mass extinctions than their warmblooded counterparts. Animals who are lower in the food chain are also more likely t…o survive. Mass extinctions, however, vary in their causes, and so also vary in their effects.
well,some animals can't survive in a climate their not used to,or not meant for it.For ex:after the Continental Drift of pangea,animals that lived in warm climates were placed… in below zero climates,which could have led to their extinction. hope this helped!
The fastest extinction of life on Earth occurred 65 million years ago when over 80% of the earth's organisms went extinct. This occurred in a relatively short 2-5 million year…s,
"It was the Cretaceous-Tertiary or the K-T Extinction." - Wrong The K-T Extinction was the mass extinction that wiped out the dinosaurs, which was more widely believed to …be caused by a heavenly body colliding with the Earth. The mass extinction that involved a large period of glaciation was in truth the Ordovician-Silurian Extinction, which was the earliest mass extinction. The extinction is associated with a period of glaciation. First, sea levels dropped as glaciers formed. Later, as the glaciers melted, the sea level rose. The cause of this glaciation remains a mystery. One suggestion is land plants caused it by absorbing large amounts of carbon dioxide from the atmosphere. The drop in carbon dioxide could then have caused global cooling.
Any event that significantly changes the environment of a particular species can cause them to become endangered or even to become extinct. If the temperature of the earth's a…tmosphere were to increase as little as 3 degrees on average, it would cause major changes in the trade winds which many bird species use for migration, which theoretically could cause their pattern to change resulting in reduced numbers. The food chain from single cells organisms living in the sea up to the to the "top" of the food chain - man, would be impacted as well. Think of the picture of the smallest fish being eaten by a larger fish being eaten by a still larger fish and so on. If the smallest fish dies, the next bigger fish has no food supply and so on up the food chain until the diet is diversified enough to be replaced.

When many types of organisms become extinct at the same time, a mass extinction has occurred.
A large enough asteroid could (theoretically) knock the Earth off of it's axis and closer or further away from the sun.
Asteroids have been known to have caused mass extinctions. The obvious one is the Cretaceous--Tertiary extinction event which wiped out the dinosaurs. Others, have also been n…oted.
In order to cause a mass extinction, something has to happen with worldwide (or nearly so) effects. In at least two of the mass extinction events for which we've determined a …likely cause, the cause was an astrobleme; an impact of a comet, asteroid or other celestial body with the Earth. In at least one other, the cause appears to have been massive volcanic eruptions, but after that long, we cannot yet determine the cause of the volcanism.
