Dr. James Hansen directs the NASA Goddard Institute for Space Studies in New York City and is Adjunct Professor of Earth Sciences at Columbia University’s Earth Institute. Since the mid-1970s, Dr. Hansen has focused on studies and computer simulations of the Earth’s climate, for the purpose of understanding the human impact on global climate. He is best known for his testimony on climate change to Congress in the 1980s that helped raise broad awareness of the global warming issue.
Environmental science and protection technicians do laboratory and field tests to monitor the environment and investigate sources of pollution, including those affecting public health.
Environmental scientists and specialists use their knowledge of the natural sciences to protect the environment and human health. They may clean up polluted areas, advise policy makers, or work with industry to reduce waste.
Hydrologists study how water moves across and through the Earth’s crust. They can use their expertise to solve problems in the areas of water quality or availability.
