The Oceans and Climate Change

Planetary atmospheric processes include many feedback loops. What are feedback loops?

• They are processes that modify an end result.

• They are various types of instruments used for measuring atmospheric properties.

• They are circular-moving loops of water that occur in offshore areas.

• They are also known as circulation cells, which occur in the atmosphere, the oceans, and inside Earth.

• They involve feeding organisms that live in the atmosphere.

Why do scientists use proxy data to reconstruct past climates?

• Proxy data fit into computer models better.

• The further back in time we go, actual measurements become less complete and more unreliable.

• Proxy data are in close proximity to the laboratories of climate scientists.

• Proxy data have already been published in established scientific journals.

An examination of natural climate change factors reveals that the recently observed climate changes, such as the rate of warming in recent decades, are greater than can be explained by natural factors.
