How does global warming affect the ocean currents?
Ocean currents are vulnerable to the effects of climate change. Cooled by the chilly polar air, this water becomes denser, and so sinks to the deep ocean, where it is pushed back towards the equator (becoming warmer, less dense and rising as it goes) by the next batch of denser water coming from above.
How is climate change affecting the ocean for kids?
What are the consequences of climate change? As ocean water warms and expands, and as polar ice caps melt, sea levels will rise and flood coastal areas where people live. Changes in average temperature, wind patterns, and ocean currents mean that some parts of the world will get hotter and some will get colder.
What will the ocean look like in 100 years?
Oceans will change color by the end of the century, as climate change significantly alters phytoplankton in the world’s seas, according to a new study. Fewer phytoplankton cause the water to look bluer, while more give it a greener hue. …
What would happen if climate change stopped?
Surface temperatures would stay elevated for at least a thousand years, implying a long-term commitment to a warmer planet due to past and current emissions. Sea level would likely continue to rise for many centuries even after temperature stopped increasing [Figure 9].
How do humans affect ocean currents?
The increase in the use of fertilisers for agriculture and warming ocean waters has contributed to eutrophication of the Ocean in certain areas of the world. This means there is less available dissolved oxygen for native sea life, which can negatively impact biological processes.
What are the effects of ocean currents?
Effects of Ocean Currents
- They result in rain. Warm currents lead to evaporation, which turns into the rain for the coastal areas.
- They can also cause deserts.
- They can destroy marine wildlife.
- They help with the continuity of life.
- They save up on time and costs.
- They can result in deaths.
What will life be like in 100 years?
In 100 years, the world’s population will probably be around 10 – 12 billion people, the rainforests will be largely cleared and the world would not be or look peaceful. We would have a shortage of resources such as water, food and habitation which would lead to conflicts and wars.
