Climate Change Careers: Arctic Biologist/Ecologist
The vast frozen ground that covers Arctic lands reveals a lot about climate change.
Scientists and researchers study the Arctic permafrost to determine how the earth is changing. Permafrost is ground that remains frozen for at least two years. According to the NRDC (Natural Resources Defense Council), permafrost covers nearly a quarter of the entire northern hemisphere and is spread throughout the Arctic regions of Siberia, Canada, Greenland, and Alaska, as well as high-altitude regions of the Rocky Mountains.
A major concern now is the melting of the permafrost. In the past several years, permafrost has thawed because of arctic warming, which has been rising at twice the global average rate. The thaw is expected to exacerbate climate change, reports the National Oceanic and Atmospheric Administration. As the frozen ground melts, microorganisms break down organic matter that then releases large amounts of greenhouse gases, including methane and carbon dioxide, that have been trapped in the permafrost.
How much of an impact thawing permafrost will have on the climate is uncertain, according to the Intergovernmental Panel on Climate Change (IPCC). This lack of clarity poses a challenge for scientists in the years to come.
Digging Beneath the Surface: What Biologists are Doing to Help Solve Climate Change
What is certain is that demand for experts to fight climate change, including biologists and ecologists, will continue to grow. The Bureau of Labor Statistics (BLS) estimates that the number of jobs for environmental scientists and specialists will rise 8% this decade.
Although similar, environmental biology differs from ecology. Environmental biology focuses on the effects human activities have on ecosystems, whereas ecology focuses on interactions between species that exist in the same ecosystem. Biologists and ecologists working within the specialty of climate change study and analyze problems in the natural world and develop solutions for them. They are part of a large community of scientists from a range of fields working together to diminish the damaging effects of climate change.
Biologists conduct significant research on the effects of global warming. Their work is at the core of strategies for managing natural resources that will reduce the impact of climate change. Ecologists monitor climate change in an effort to understand and predict what the effects will be on ecosystems, wildlife, and humans.
Removing greenhouse gasses, such as those caused by the thawing permafrost, is among several efforts scientists are working on to help plant life, animals, and people adapt to environmental changes. According to a report published by the Biotechnology Innovation Organization, the biotech sector could help remove 3 gigatons of carbon dioxide—or nearly half of the total annual emissions of the United States—from the atmosphere every year by 2030. This is just one estimate that shows how important the work of life scientists is in the fight against climate change.
The complexity of global climate change sends a clear message: More work is needed.
Responding to the environmental crisis requires the expertise of scientists in several fields, including biology and ecology. Their knowledge is needed to help create a sustainable future.
If you feel work in science and climate change is your calling, explore John Carroll University’s life sciences degrees—Biology, Cell and Molecular Biology, and Environmental Science. As a John Carroll University student, you will have the opportunity to take part in the Jesuit commitment to environmental causes.
Choose a bachelor’s degree program and learn to solve science’s challenging problems. Engage in relevant courses, such as Climate Change: Global Impacts, which examines issues surrounding climate change.
