I will give whoever answers these questions as accurately as possible the Brainliest. 1. Describe the normal flow of ocean currents along and off the west coast of South America.
2. How does the flow of the El Nino current differ from that of the normal ocean currents?
3. Compare and contrast the air-pressure systems off the west coast of South America and north of Australia during a normal period and during El Nino.
4. Describe the change in the polar jet stream during El Nino.
5. What climate changes does El Nino bring to North America?
6. What climate change does El Nino bring to Australia?
7. Would cold-water fish species be easier to catch along the northwest coast of South America during El Nino or normal periods? Explain your answer.

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
