Global climate change threatens all of Earth's biomes. The rainforest biome is especially at risk due to species' inability to adapt to temperature and precipitation changes. Tundra and desert biomes may no longer support their current vegetation. Oceans are also impacted through changes in circulation, erosion, sea levels, and species distribution. All biomes will experience fluctuations that endanger existing plants and animals.

1. Global Climate Change and the earth’s Biomes By Shannon Storey

2. What is a biome? A biome is a large geographical area that is inhabited by particular plant and animal groups. The climate and terrain of a region determine which biomes are able to exist there. Major biomes include deserts, tundra, grasslands, forests, and various aquatic environments.

4. Tundra The tundra occupies earth’s northern hemisphere. Soil is poor in nutrients and permafrost allows for little room for deep rooting plants and trees. It is the coldest of all biomes.

5. Desert Deserts cover nearly 1/5 of our planet. They receive very little rain. Vegetation consist of plants that have evolved to retain water. Most animal species are nocturnal to cope with the unbearable heat during the day.

6. Forest Forests represent 1/3 of the earth’s land. They are found all over the world. They are characteristic for their vast variety of trees. Rainforests are a wet climate area. They are known for their numerous plant and animal species.

7. Grasslands Grass is the dominant plant life here. Serve as grazing areas for many animals and are commonly used as farmland for humans.

8. Aquatic Water covers approximately 75% of our planet. There are two types of aquatic biomes: marine and freshwater. The marine region consists of oceans, coral reefs, and estuaries. The freshwater region exists in lakes, ponds, swamps, etc.

9. Which biome is most impacted by global climate change? All of them! Some scientists argue that the rainforest biome is the most at risk due to species being less accustomed to fluctuations in temperature and precipitation. The tundra and desert biomes are also threatened and may no longer be capable of supporting the same vegetation they do now in the years to come. Our oceans are also taking a toll due to global climate change. Oceanic circulation, coastal erosion, sea-level rise, and changes in species distribution and migratory routes are just a few of the issues being studied and documented today.
