Climate change has caused mass extinctions of species throughout geologic time, dating back millions of years. The earth goes through cyclic temp changes constantly, and species adapt, evolve, or simply die out. The current period of "climate change" has not been severe enough yet to cause any major fauna extinctions as of this time, and chances are good that it may not, as the warming claims may have been exaggerated.

What is global extinction?
Global extinction refers to the complete loss of a species worldwide. This occurs when all individuals of a particular species are no longer alive and no longer exist. Global extinctions can be caused by various factors, such as habitat destruction, climate change, pollution, or natural disasters.
What has caused most of the mass extinctions on earth?
Mass extinctions are caused by rapid, global changes. Usually these are changes in climate. Without the right temperatures and precipitation, plants that animals depend on die out, which wipes out the animals. Examples include the Permian-Triassic Extinction, where volcanoes in what is now Siberia caused intense global warming, wiping out over 90% of species, and the K-T Extinction, where an asteroid impact suddenly blocked sunlight for months or years, killing off the dinosaurs and many other organisms.
What was the first animal to ever go extinct because of global warming?
The white possum. This creature was the first animal to go extinct because of global warming. Its extinction was caused by the heat wave of global warming bringing temperatures higher than the possums could cope with.
Does the disappearance of a bird cause changes in climate?
No, this would have no effect on climate. Climate change is caused by global warming.
Why is the extinction of the dinosaurs attributed to an asteroid impact?
The original observation was that in the fossil records there is a layer with high levels of iridium and osmium at the time of dinosaur extinction. Iridium and osmium are common is asteroids. For the layer to be all over the globe it must have been a major strike which would have caused global wide climate change causing a mass extinction.
Can you quote another term for global warming?
Climate change. Though that is actually caused by global warming.
What are the conditions that threaten the animal's survival?
Climate changes and global warming.
Which Arctic animal do many scientists consider the most vulnerable to extinction due to global warming?
The polar bear is considered one of the most vulnerable Arctic animals to extinction due to global warming. Their sea ice habitat is melting rapidly, leading to decreased hunting opportunities and increased competition for resources. Climate change is also affecting their ability to reproduce and find food, making them highly susceptible to extinction.
Is there a Mass extinction in the Jurassic period?
There was a minor extinction event at the end of the Jurassic period. It was probably caused by global climate change. Dinosaurs like Allosaurus, Ceratosaurus, Camarasaurus, and Stegosaurus couldn't adapt to the change in temperature, so they all died out. The Cretaceous period then came after the Jurassic period had ended.
How have astronomical conditions contributed to global climate changes?
They haven't. Scientists agree that global climate change is caused by human burning of fossil fuels and deforestation.
Why did the andrewsarchus go extinct?
andrewsarchus might have gone extinct during the central Asian extinction caused by the formation of the Himalaya Mountains 40 million tears ago or because of Habitat loss maybe Global warming and Climate change
What could cause an extinction of global species?
Climate change, people slaughtering too many of the species, lack of food, ect.
