Climate change has a big impact on where animals and plants live, and how they interact with each other in their environment. To help make sense of this, let's look at the difference between a habitat and a niche.
Habitat: This is the place where an organism lives. It includes things like soil, water, temperature, and plants.
Niche: This is the job that an organism does in its habitat. It includes its interactions with other creatures and how it uses resources.
Rising Temperatures: The Earth's average temperature has gone up about 1.2°C since the late 1800s. This can make it hard for some species to find a suitable place to live, especially those that need certain temperature ranges.
Changes in Rainfall: Rain patterns are changing too. Some areas might have too little rain, leading to droughts, while others could get too much, causing floods. For example, a place suffering from drought might have fewer freshwater habitats, which hurts fish and other water animals.
Rising Sea Levels: Sea levels have risen by about 20 centimeters since 1901. This threatens coastal areas like mangroves and salt marshes, which many plants and animals rely on to survive.
Habitat Fragmentation: Because climate change affects regions differently, it can break up habitats. This means that some animals are stuck in small, isolated areas. This makes it hard for them to find mates and food, which can threaten their survival.
Movement of Species: As climates change, some animals and plants might move to new areas. A study found that many species have been moving closer to the poles by about 6.1 kilometers each decade. This can disrupt existing niches because new species come in and compete for resources.
Food Web Changes: Climate change can affect plants that are the base of our food webs. If flowers bloom earlier due to warmer weather, pollinators might not be in sync with them, which could hurt both kinds of species.
Invasive Species: Warmer weather can help non-native species to invade new areas. They can outcompete local species for food and space. This can lead to fewer native species and reduce biodiversity, as invasive species can thrive in similar niches.
Shifting Relationships: Climate change can change how predators and prey interact. If a key species in an ecosystem is affected, it can create a ripple effect that impacts many others, harming biodiversity.
Loss of Biodiversity: The World Wildlife Fund (WWF) warns that climate change could cause 1 million species to go extinct in just a few decades if things keep progressing like this. Losing biodiversity can harm ecosystems and make them less resilient.
Ecosystem Services: Healthy ecosystems provide important services like clean air, water purification, and pollination. If habitats and niches are disrupted, these services might not function as well.
Struggles to Adapt: Many species might find it tough to adapt quickly to climate change. Research shows that species usually need tens of thousands of years to adjust to major changes, but right now, things are changing much faster.
To sum up, climate change is a serious threat to the habitats and niches where plants and animals live. As ecosystems get disrupted, the balance between species is in danger, which can lead to negative effects on biodiversity and the overall health of the environment. Understanding these impacts is really important for creating effective ways to protect nature and handle the effects of climate change.
