Special Issue on Global Warming
by Brian Peterson (editor, Miami Education Review)
MER will devote several issues to environmental problems in China and possibly India. We are interested in whether environmental problems are likely to stymie economic development in those nations before 2050. In order to get a global context for this, we are devoting this issue to the problem of global warming.
MER has covered global warming in the past and we were dismayed to learn that the earth could naturally decide to heat up or cool down of its own volition, regardless of any human tampering. And it could be that temperature increases resulting from human activity could trigger some mechanism that would result in a serious cold spell.
Human beings are just one more chaotic element in an already unstable climate history. But there is no serious question but what human activity is contributing toward a rise in global temperatures that could have disastrous effects within a hundred years.
We are interested in figuring out the biggest contributors to global warming and what can be done to minimize this problem. The human causes of global warming include: vehicle exhaust gases; industrial greenhouse gases; home heating and cooking; and soot from smoke and diesel exhaust which diminishes the reflectivity of snow.
We were surprised in preparing this issue of MER to see that several Asian cities have banned two-stroke engines because of the great amount of exhaust that they emit (they mix oil with gas and burn the fuel very inefficiently). And one Arizona city has banned old diesel engines.
Less-developed countries are being more responsive to at least some environmental problems than we had believed them capable of. That is a very good sign.
Hydrogen fuel cells may one day replace internal combustion engines. But capitalism is seldom willing to go totally clean, and we found a vivid Village Voice article on the nasty environmental secrets behind the making of fuel cells.
It seems as if we chose just the right time to do an issue on global warming, because there is a huge amount of material including a brand new study on the future extinction of a million animal species if global warming is not stopped.
