Nature, 1970
A comparison of the Earth with the Moon and other planets can help considerably in the solving of geophysical problems. Professor Cook deals with some of these problems in this article, which is a summary of the inaugural lecture he gave as professor of geophysics at Edinburgh on January 15.

Trophic Downgrading of Planet Earth
Science, 2011Until recently, large apex consumers were ubiquitous across the globe and had been for millions of years. The loss of these animals may be humankind’s most pervasive influence on nature. Although such losses are widely viewed as an ethical and aesthetic problem, recent research reveals extensive cascading effects of their disappearance in marine ...

A Final Warning to Planet Earth
Trends in Ecology & Evolution, 2018In Ripple et al. [1], 15 364 scientists from 184 countries issue a ‘warning to humanity’ and present a radical agenda to protect planet Earth. We, the billions of people believing in human exceptionalism, categorically reject this agenda and issue in return a stark warning to planet Earth. No amount of facts showing that planet Earth is in a dire state

Creep in the Earth and Planets
Tectonophysics, 1972Abstract Evidence of imperfectly elastic behaviour in the earth and planets is provided by the following phenomena: 1. (1) damping of the earth's free nutation; 2. (2) damping of elastic waves passing through the earth; 3. (3)secular acceleration of the moon; 4. (4) figure of the moon; 5. (5) figure of the earth; 6.

The article focuses on ideas for halting global warming that utilize geoengineering, or deliberately altering the climate with technology. Ideas fit into two categories: affecting how much sunlight reaches Earth's surface or affecting how much heat escapes into space, which involves carbon dioxide (CO2).

Scientific American, 1989
Every form of life continually faces the challenge of reconciling its innate capacity for growth with the opportunities and constraints that arise through its interactions with the natural environment. The remarkable success of our own species in meeting that challenge is only the beginning of the story.
