This article examines the sixth of seven essential principles of the climate sciences--"We Change Earth's Climate." Written for the science teacher, the article covers greenhouse gases, land-use changes, and other human-induced causes of global climate change. Each issue of the free online magazine Beyond Weather and the Water Cycle is structured around one of the seven principles. The content provides background information, lessons, and activities for K-5 classrooms.

Focusing primarily on the period since 1500, explores the influence of climate, topography, plants, animals, and microorganisms on human history and the reciprocal influence of people on the environment. Topics include the European encounter with the Americas, the impact of modern technology, and the historical roots of the current environmental crisis.

This video segment adapted from the NOW-RAMP 2002 Expedition documents a research expedition to Pearl and Hermes Atoll in Hawai`i. Watch as biologists assess the bird and plant populations and then work to eradicate invasive species.

In this video from Outdoor Nevada, Brian Wignall speaks with an ornithologist about the peregrine falcon, a majestic and endangered species that is one of the fastest animals in the world.

The deep continental margins were once perceived as monotonous mud slopes of limited ecological or environmental concern. Technological advances now reveal unexpected diversity, with a mosaic of lush habitats and ecosystems that support varied and unusual species fundamental to the health of the ocean and our own lives. Join Scripps biological oceanographer Lisa Levin as she reveals how changes in ocean temperature and chemistry, as well as growing economic opportunities, are placing new pressures on deep-ocean ecosystems, just as we are getting to know them.
