How does climate change affect biology?
Climate has far reaching impacts on biological systems. Climate change can disrupt the match between organisms and their local environment, reducing survival and reproduction and causing subsequent impacts on populations or species’ distributions across geographic regions.
How does climate change affect aquatic organisms?
Increases in water temperatures as a result of climate change will alter fundamental ecological processes and the geographic distribution of aquatic species. Populations of aquatic organisms are sensitive to changes in the frequency, duration, and timing of extreme precipitation events, such as floods or droughts.
What marine species are affected by climate change?
In polar seas, species adapted to life on or under sea ice are directly threatened by habitat loss due to climate change. The Arctic and Southern Oceans are home to a rich diversity of life, from tiny plankton to fish, krill and seafloor invertebrates to whales, seals, polar bears or penguins.
Is climate change considered biology?
Climate has a pervasive influence on individual plants and animals, populations, communities and entire ecosystems. Changes in climate will have far reaching effects on all aspects of biology. Climatic changes over the past several decades have already produced measurable changes in biological systems worldwide.
How does climate change affect marine mammals?
Climate change models predict changes to the sea ice leading to loss of the sea ice habitat, elevations of water and air temperature, and increased occurrence of severe weather. The loss of sea ice habitat will reduced the abundance of seal prey for marine mammals, particularly polar bears.
How are marine mammals affected by climate change?
Climate change is causing slower formations of sea ice, quicker decline and thinner ice sheets. Polar bears and other Arctic marine mammals are losing their habitat and food sources in result of the sea ice decline. Polar bears rely on seals as their main food source.
How does climate change affect coasts?
Climate change is causing sea level rise, which is increasing the risk of flooding around the UK’s coastline. It is also increasing coastal erosion. Both of these hazards pose a risk to people and the environment.
How global climate change affects marine primary productivity and marine animal migration?
Changes in water temperature can affect the environments where fish, shellfish, and other marine species live. As climate change causes the oceans to become warmer year-round, populations of some species may adapt by shifting toward cooler areas. At the same time, these 105 species moved an average of 18 feet deeper.
