How the World Really Works

apocalypse by 2030 or 2050. Oxygen will remain abundant. Concerns about water supply will increase in many regions, but we have the knowledge and we should be able to mobilize the means needed to avert any mass-scale life-threatening shortages. And we should not only maintain but improve average per capita food supply in low-income countries, while

Even though the supply of new renewables (wind, solar, new biofuels) rose impressively, about 50-fold, during the first 20 years of the 21st century, the world’s dependence on fossil carbon declined only marginally, from 87 percent to 85 percent of the total supply, and most of that small relative decline was attributable to expanded hydroelectrici

The human race, Saul Griffith has estimated, currently consumes energy at an average rate of approximately 16 trillion watts, or sixteen terawatts—the equivalent of 160 billion hundred-watt lightbulbs burning all the time. Capping atmospheric greenhouse gas at 450 parts per million—a level that’s 15 percent higher than today’s and that climatologis

And how will we deal with unfolding climate change? There is now a widespread consensus that we need to do something to prevent many highly undesirable consequences, but what kind of action, what sort of behavioral transformation would work best? For those who ignore the energetic and material imperatives of our world, those who prefer mantras of g

The real wrench in the works: we are a fossil-fueled civilization whose technical and scientific advances, quality of life, and prosperity rest on the combustion of huge quantities of fossil carbon, and we cannot simply walk away from this critical determinant of our fortunes in a few decades, never mind years.
