Climate change is having profound impacts on the environment, and in turn, on human and animal life around the world. As global temperatures rise due to increased greenhouse gas emissions, weather patterns are being disrupted, sea levels are rising, and ecosystems are under threat. Here are some of the major ways climate change is impacting life on Earth:
Effects on Plants and Animals
Changing weather and temperature patterns are causing some species to shift their geographic ranges to cooler climes. However, not all species are able to adapt or migrate fast enough. According to the IPCC, if global temperatures rise more than 1.5-2°C from pre-industrial levels, 18% of insects, 16% of plants, and 8% of vertebrates are projected to lose over half their geographical habitat range.
Increasing heat waves, droughts, and extreme weather are causing die-offs of plants and animals that cannot cope with temperature and precipitation changes. Mass bleaching events are devastating coral reefs around the world.
Ocean acidification from excess CO2 is damaging marine ecosystems. Shellfish, corals, and plankton are particularly affected. This impacts entire food chains.
Invasive insects, animals, and plant species are spreading to new habitats as conditions change, disrupting native ecosystems.
Effects on Humans
Climate change is having profound impacts on the environment, and in turn, on human and animal life around the world. As global temperatures rise due to increased greenhouse gas emissions, weather patterns are being disrupted, sea levels are rising, and ecosystems are under threat. Here are some of the major ways climate change is impacting life on Earth:
Reduced crop yields due to heat, drought, and changing rainfall patterns is threatening food security, particularly in vulnerable developing regions. Rice and wheat yields are projected to decline in tropical areas.
Increased frequency of extreme weather like floods, hurricanes, and storms is endangering human lives and infrastructure. Heat waves are also becoming more common and intense, causing deaths.
Vector-borne diseases like malaria, dengue fever, Lyme disease, and West Nile virus are spreading as temperatures warm, affecting larger portions of the population.
Rising sea levels are making coastal communities more vulnerable to erosion and flooding, especially island nations and coastal cities. 13 million Americans living near coasts could be displaced by 2100.
Actions Needed
Climate change poses a major threat to life on Earth. Concerted global action is urgently needed to reduce greenhouse gas emissions and adapt to unavoidable changes. Individuals can also help by reducing their carbon footprint. We must act now to protect ecosystems and future generations from the most severe impacts of climate change.
