Human activities contribute to climate change by causing
changes in Earth’s atmosphere in the amounts of greenhouse gases, aerosols (small particles), and cloudiness. The largest known
contribution comes from the burning of fossil fuels, which releases
carbon dioxide gas to the atmosphere. Greenhouse gases and aerosols affect climate by altering incoming solar radiation and outgoing infrared (thermal) radiation that are part of Earth’s energy
balance.
Its classic greek literature hope this helps ;)
It's a fragment because it needs a complete cause.
The predicate is the very and everything that follows after it, which could include adverbs, prepositional phrases, and other parts of speech. For example, "The dog ran across the street to the neighbor's house". Find the verb (the action or in your case, a linking verb such as is, are, was, wear, am). In my example, the verb is 'ran'. So the predicate is:
-ran across the street to the neighbor's house
For your sentence, the predicate is -was very strong.
