Low wage workers have far more education than they did in in 1968, but they make far less

The minimum wage is 23 percent less than its peak inflation-adjusted value in 1968. This is despite productivity (how much output can be produced in an average hour of work in the economy) more than doubling in that time period. The low-wage workforce has surely contributed to this rise in economy-wide productivity, since as a group they have far more education now than they did then. For the workforce overall, 37 percent in 1968 had not completed high school (or received a GED), which was true for only 9 percent in 2012 (the latest year with comparable data). We can drill down to examine low-wage workers, which we are defining for this analysis as those earning in the bottom fifth of the wage distribution.

The U.S. has caused more global warming than any other country. Here is how the Earth will get its revenge.

Last year, we learned what is probably the worst global warming news yet — that we may have irrevocably destabilized the massive ice sheet of West Antarctica, which contains the equivalent of nearly 11 feet of sea level rise. The rate of West Antarctic ice loss has been ominously increasing, and there are fears that if too much goes, the slow and long-term process of ice sheet disintegration could accelerate.

Climate-induced migration creates perils, possibilities

For Pacific islands like Palau, Tuvalu and Kiribati, the implications of climate change are clear – and devastating. Already, these governments have begun to plan for a future in which entire populations have to relocate as their islands vanish under the rising sea. But climate change also threatens ways of life in subtler ways, leaving families around the world to work out for themselves how to cope.

UN says lag in confronting climate woes will be costly

Nations have so dragged their feet in battling climate change that the situation has grown critical and the risk of severe economic disruption is rising, according to a draft United Nations report. Another 15 years of failure to limit carbon emissions could make the problem virtually impossible to solve with current technologies, experts found.
