What would most likely trigger a climate change that could lead into a mass extinction?
Two hundred years of burning fossil fuels is already triggering a climate change that could lead to a mass extinction of all life on Earth.
Earth's collision with a huge asteroid. All of the volcanoes exploding at once would also.

Volcanic debris changes the climate.
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.
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....
Mass extinctions could be caused by giant meteors colliding with the Earth. They could also be caused by the Earth tipping off its axis. Global warming or global cooling will …affect many colder climate animals which would cause them to die out.
The movements of continents has nothing to do with the presentclimate change, which is being caused by global warming. However, in the long term, tectonic plate shift, which …producesmountain ranges like the Andes and the Rockies, is responsible, forexample, for the differing climates on both sides of these ranges
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,
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.
Global warming is warming our planet and melting our polar icecaps. Eventually these polar icecaps will completely melt, this will make certain animals extinct such as the pen…guin and the polar bear. the melting will raise the sea levels and cause all other species on land to die out.

If the meteorite is large enough it would knock enough dust intothe air to freeze the world. The dust could block out the sunlight.
Climate change would cause the types of plants that grew in an area to change. If the plants that mammoths needed for food were replaced by plants that didn't provide enough n…utrition, the mammoths would have died out.
