How Does Climate Change Affect Earth’s Oceans Quizlet?

Climate change has a direct impact on the oceans, affecting everything from sea levels to ocean temperatures. As the Earth’s climate changes, the oceans are absorbing more heat and carbon dioxide, resulting in the rise of sea levels, changes in ocean currents, and more severe storms. In addition, climate change is causing acidification of the oceans, which results in a decrease in pH levels that can have devastating effects on marine life. In this article, we will explore how climate change is affecting the oceans and what the implications are for the future.

Rise of Sea Levels

One of the most visible impacts of climate change on the oceans is the rise of sea levels. As the atmosphere warms, the oceans absorb more heat and water vapor, causing the sea levels to rise. This is exacerbated by the melting of glaciers and polar ice caps, which add more water to the oceans. According to the Intergovernmental Panel on Climate Change, global average sea levels could rise by up to 1 meter by the end of this century. This would cause flooding and erosion in coastal areas, displacement of people, and destruction of habitats.

Changes in Ocean Currents

Changes in ocean currents can also be attributed to climate change. Ocean currents move warm and cold water around the world, helping to regulate global climate. As the oceans absorb more heat, the currents become more unpredictable, which can lead to more severe storms, floods, and droughts. Additionally, changes in the currents can disrupt the natural migrations of marine life, leading to disruption in the food chain and loss of biodiversity.

Acidification of the Oceans

As the Earth’s atmosphere warms, more carbon dioxide is being released into the atmosphere, which is then absorbed by the oceans. This causes the pH levels of the oceans to decrease, a process known as ocean acidification. This has drastic implications for marine life, as the decrease in pH levels makes it harder for many species to survive. Ocean acidification can also lead to coral bleaching, which is when coral reefs die off due to changes in their environment.


Climate change is having a profound effect on the world’s oceans, leading to rising sea levels, changes in ocean currents, and acidification of the oceans. These changes can have devastating impacts on marine life, leading to disruption in the food chain, loss of biodiversity, and destruction of habitats. It is important for us to take action to reduce our carbon emissions in order to mitigate the effects of climate change on the world’s oceans.
