1. Global warming is the change in the climate of the earth causing it to heat up whereas the greenhouse effect is a naturally occurring phenomena, constantly occurring due to the atmosphere and sunlight.

A claim is an unverified statement or theory which is made about something which may or may not be true.
<h3>Verification of a claim</h3>
For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.
With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.
If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.
Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.
