Some of the heat given off by the earth is trapped in the atmosphere by gases
such as water and CO2
Some of the heat given off by the earth escapes into space.
How greenhouse gases keep the earth warm.

Increased CO2 causes the atmosphere to retain more heat by catching more heat
given off by the earth.

Dr. Camille Parmesan's early research focused on multiple aspects of population Dr. Camille Parmesan's early research focused on multiple aspects of population biology, including the ecology, evolution and behaviors of insect/plant biology, including the ecology, evolution and behaviors of insect/plant interactions. For the past several years, the focus of her work has been on interactions. For the past several years, the focus of her work has been on current impacts of climate change in the 20th century on wildlife. Her work on current impacts of climate change in the 20th century on wildlife. Her work on butterfly range shifts has been highlighted in many scientific and popular press butterfly range shifts has been highlighted in many scientific and popular press reports, such as in reports, such as in Science, Science News, Science, Science News, New York Times, London Times, New York Times, London Times, National Public Radio, and the recent BBC film series "State of the Planet" with National Public Radio, and the recent BBC film series "State of the Planet" with David Attenborough. The intensification of global warming as an international David Attenborough. The intensification of global warming as an international issue led her into the interface of policy and science. Parmesan has given issue led her into the interface of policy and science. Parmesan has given seminars in DC for the White House, government agencies, and NGOs (e.g., IUCN seminars in DC for the White House, government agencies, and NGOs (e.g., IUCN and WWF). As a lead author, she was involved in multiple aspects of the Third and WWF). As a lead author, she was involved in multiple aspects of the Third Assessment Report of the IPCC.Assessment Report of the IPCC.
