Robert Ballard

Ballard grew up in Pacific Beach San Diego, California to a mother of German heritage and a father of British heritage. He has attributed his early interest in underwater exploration to reading the novel Twenty Thousand Leagues Under the Sea, living by the ocean in San Diego, and his fascination with the groundbreaking expeditions of the bathyscaphe Trieste.

According to scientists, saving wildlife from the threat of global warming requires more than reducing global warming pollution. To help wildlife cope with the stress caused by climate change, natural resource managers must take action to reduce non-climatic stressors. In the case of the polar bear, this means that natural resource managers must limit oil and gas development in the polar bear's habitat. The Alaskan polar bear population relies heavily on the Arctic coastal plain for denning. It also relies on the ice on the Beaufort and Chukchi seas for both denning and hunting. Both of these habitat areas are threatened by increasing oil and gas development. Although the polar bear is now listed as a threatened species, the Secretary of Interior limited certain protections for the polar bear and will allow oil and gas development to continue in important polar bear habitat.

Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased emission of greenhouse gases. Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while long wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.
