The Quadruple Squeeze

The planetary squeeze, or the driving forces that explain why we’ve ended up with rising environmental risks, originate from four different areas: population pressure in terms of numbers and affluence, human-caused climate change in terms of the concentration of greenhouse gases, the inability of the Earth system to buffer the effects of climate change, and the element of surprise. The space within which we can operate safely has been reduced -- we can no longer exclude abrupt, sudden changes, what are called “tipping points” or “thresholds.” Examples explore quadruple squeezes using graphs and data.
