Fertilizer production ond other human activities have more than doubled the global rate of nitrogen fixation since preindustrial times. The resulting imbalance is contributing to ecosystem disruption, ozone depletion, greenhouse effects and other environmental problems.

Physics Today 47 (11), 36–42 (1994); https://doi.org/10.1063/1.881424

Covering the Earth on scales as large as millions of square kilometers, airborne water particles transport energy and affect the balance between incoming and outgoing radiation.

Physics Today 47 (11), 45–50 (1994); https://doi.org/10.1063/1.881425

Each second millions of cubic meters of water circulate between the ocean's surface and its depths. Despite the crucial role this ‘overturning’ may play in regulating Earth's climate, we still do not know how vulnerable it is to anthropogenic environmental changes.

Physics Today 47 (11), 54–61 (1994); https://doi.org/10.1063/1.881426

What the world needs now is an environmentally benign way to generate electric power efficiently. The emerging technology of fuel cells is rising to meet the challenge.

Physics Today 47 (11), 63–68 (1994); https://doi.org/10.1063/1.881405

With the environment in jeopardy, we need to reconsider the design of products and the organization of industrial and consumer markets with recycling in mind.
