Climate Change

On a rainy, misty day

The black sand that makes up the famous Hawaiian black sand beaches is made out of basalt. These beaches can form rapidly when molten lava meets the cold ocean water in an explosive confrontation. The shattered volcanic rock is further broken down as it is smashed together by the waves. Black sand beaches can be relative short lived. This photo shows the black sand of Maui's Pa'iloa beach.

Yet amid all this natural loss, human beings, on the aggregate have largely thrived. That’s definitely true compared to the days of Columbus -- the economist Angus Maddison estimates that between 1500 and 2008, global average per-capita gross domestic product multiplied by more than thirteenfold. Much of that gain has occurred in recent years, as globalization helped life more than a billion people out of extreme poverty in the developing world since 1990 alone -- the same year when environmental damage, including the first signs of climate change, began compounding. Nor is the smply a story of GDP. The Human Development Index is opposite statistic developed by the Pakistani economist Mahbub ul Haq to track life expectancy and education, as well as per capita income. . . . Page 149

While the causes of climate change are distributed around the world, the effects of warming are primarily distributed in the future. There is a time lag built into the machinery of climate change. Even if we somehow halted all man made greenhouse gas emissions today -- no more coal, no more oil, no more gasoline -- the climate would continue to warm by an additional 0.5 degrees simply because of the greenhouse gases emitted in the past, going all the way back to the Industrial Revolution. ~ page 156
