If the climate is always changing over the history of the planet, why should we get worked up about global warming?
<|assistant|>
It is true that climate change has been occurring naturally for as long as the planet has existed, but human activities are now causing climate change to happen at a rapid pace. This is problematic because certain effects of climate change are unprecedented and could have disastrous consequences if left unchecked. Therefore, it is important that we take proactive measures to mitigate its effects.
