How is Oceania being affected by climate change?

Sea-level rise, the increased frequency and severity of extreme weather events, increasing air and sea surface temperatures, floods and protracted droughts, coastal erosion, salt water intrusion, and salinization are threatening island economies and habitats.

Why is climate change a concern for the region of Oceania?

In fact, many scientists argue that Australia and Oceania is the continent most vulnerable to climate change because of its climate and geography. The heavily coastal populations of the continent’s small islands are vulnerable to flooding and erosion because of sea level rise.

How are coral reefs affected by climate change?

Climate change leads to: A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease. Sea level rise: may lead to increases in sedimentation for reefs located near land-based sources of sediment. Sedimentation runoff can lead to the smothering of coral.

How does global warming affect the environment?

Global warming stresses ecosystems through temperature rises, water shortages, increased fire threats, drought, weed and pest invasions, intense storm damage and salt invasion, just to name a few.

What does the ocean do for our climate?

The oceans also regulate the global climate; they mediate temperature and drive the weather, determining rainfall, droughts, and floods. They are also the world’s largest store of carbon, where an estimated 83% of the global carbon cycle is circulated through marine waters.
