Environmental Science and Climate Change

Ammonia, a compound consisting of nitrogen and hydrogen, is a commonly used industrial chemical and a potential carbon-free fuel with significant environmental impacts.

Water covers about 71% of the Earth's surface, predominantly in the form of oceans, glaciers, and groundwater.

Climate tipping points are critical thresholds where a tiny change can push the climate system into a dramatically different state.

Built in the 1980s in Arizona, Biosphere 2 is a vast, enclosed ecological system designed for studying ecosystems and human interaction, housing researchers and serving as a model for sustainable living.

Wildlife crossings are structures that allow animals to cross human-made barriers safely, reducing wildlife-vehicle collisions and supporting biodiversity.

Air quality varies widely across the globe, influenced by various factors and resulting in significant disparities.

The Pacific Northwest's seismic activity is largely defined by the Cascadia subduction zone, where the Juan de Fuca Plate meets the North American Plate, shaping the region's dynamic tectonic landscape.

Climate change refers to significant and lasting changes in the Earth's weather patterns and temperatures.

California's volcanic landscape is diverse and dynamic, shaped by eruptions past and present, with iconic features like Lassen Peak and the Long Valley Caldera.

Habitat fragmentation worsens death tolls by restricting movement during disasters like the Haiti earthquake.
