How does global climate change affect ocean currents?
If global warming results in increased rainfall in the North Atlantic, and the melting of glaciers and sea ice, the influx of warm freshwater onto the sea surface could block the formation of sea ice, disrupting the sinking of cold, salty water.
What are 4 effects of global climate change?
Increased heat, drought and insect outbreaks, all linked to climate change, have increased wildfires. Declining water supplies, reduced agricultural yields, health impacts in cities due to heat, and flooding and erosion in coastal areas are additional concerns.
How does climate change affect the ocean quizlet?
How does climate change affect earth’s oceans? The pH level of the ocean will shift to a more acidic environment, leading to stress and the possible extinction of many species of shellfish and corals.
How does climate change affect the ocean animals?
The ocean absorbs most of the excess heat from greenhouse gas emissions, leading to rising ocean temperatures. Increasing ocean temperatures affect marine species and ecosystems. Rising temperatures cause coral bleaching and the loss of breeding grounds for marine fishes and mammals.
What is the overall effect of the oceans on Earth’s climate quizlet?
a) As ocean surface temperatures increase, the energy transferred to the atmosphere increases air temperatures. There is a lag time as the heat capacity of oceans release heat slowly. Land areas closest to the ocean receive more mild temperatures than areas farther inland.
How does warming of the ocean affect sea level quizlet?
Sea levels are rising due to increased temperatures causing water to expand and ice to melt which then runs off into the seas. The oceans absorb carbon dioxide and this makes them slightly acidic. As they warm they absorb less carbon dioxide which is a problem for marine life.
How does climate change affect the Pacific ocean?
Climate change presents Pacific Islands with unique challenges including rising temperatures, sea-level rise, contamination of freshwater resources with saltwater, coastal erosion, an increase in extreme weather events, coral reef bleaching, and ocean acidification.
