...fact played a signal role in destroying Detroit. He was hardly alone; if you wanted to get elected in southeastern Michigan, you had to support the party line dictated by the Big Four - GM, Ford, Chrysler and their co-conspirator the United Auto Workers. Anything that might limit the industry's income was bad for the auto industry, and anything bad for the auto industry was deemed dangerous to Detroit...
...even while Obama talked up the importance of the Copenhagen process and hyped his Administration's domestic initiatives on climate change, including new rules that would limit greenhouse-gas emissions from automobiles, many environmental groups came away from his speech underwhelmed. Obama made no mention of specific targets for U.S. emissions cuts at Copenhagen, nor did he agree to attend the summit himself - as British Prime Minister Gordon Brown has done. He spent much of his speech focusing on the need for major developing nations like China to make their own moves on climate change, which sounded a little hypocritical...
Regarding climate change, for instance, Rockstrom proposes an atmospheric-carbon-concentration limit of no more than 350 parts per million (p.p.m.) - meaning no more than 350 atoms of carbon for every million atoms of air. (Before the industrial age, levels were at 280 p.p.m.; currently they're at 387 p.p.m. and rising.) That, scientists believe, should be enough to keep global temperatures from rising more than 2°C above pre-industrial levels, which should be safely below a climatic tipping point that could lead to the wide-scale melting of polar ice sheets, swamping coastal cities. "Transgressing these boundaries...
...problem is that identifying those limits is a fuzzy science - and even trickier to translate into policy. Rockstrom's atmospheric-carbon target of 350 p.p.m. has scientific support, but the truth is that scientists still aren't certain as to how sensitive the climate will be to warming over the long-term - it's possible that the atmosphere will be able to handle more carbon or that catastrophe could be triggered at lower levels. And by setting a boundary, it might make policymakers believe that we can pollute up to that limit and still be safe. That...
...Rivard, editor of the San Antonio Express-News and chair of the IAPA committee on freedom of expression, which held an emergency forum in Caracas over the weekend. "They probably can't gain the kind of grip on their respective countries without passing laws to legitimize their moves and limit independent media...
