...consensus of analysts estimates is for a 27% earnings rise for S&P 500 stocks in 2010, but even if this is achieved companies will be earning 9% less in 2010 than they did in the peak 2007 period. Steven Wieting, a managing director and U.S. economist at Citigroup Global Markets, says it will likely be 2012 or 2013 before earnings reach the levels attained in 2007. Maybe by then we'll be back to the stock-market highs that occurred...
...agree that more regulation was not the answer to avoiding another financial crisis. John Thompson, chairman of security company Symantec and a former adviser to President George W. Bush, said to the executives, "Some of this oversight is management's responsibility, and not regulation." (See pictures of the global financial crisis...
...carbon dioxide gets most of the attention when it comes to greenhouse gases, but it's not the only one that's warming the earth. Methane - a gas that is found in everything from landfills to cow stomachs - also plays a big role. Although global methane-emissions levels are much lower than CO2 emissions, pound for pound methane is a more powerful greenhouse gas; a ton of it has 23 times the warming effect of a ton of CO2. And methane, like CO2, is on the rise thanks to us: about 60% of global methane emissions come from man-made...
...acting as sources and sinks simultaneously. The challenge has been trying to tease out how those two functions balance out, but a new paper in the Jan. 14 issue of Science has provided some hard numbers. Using satellite data, investigators determined that wetlands contribute from 53% to 58% of global methane emissions and that rice paddies are responsible for more than a quarter of that output. The study could help make climate-change models more accurate, and help scientists understand whether increasing temperatures will lead to even higher methane emissions down the road. "It's all about more accurately describing...
...unleash masses of buried methane - which would then further warm the atmosphere, releasing more methane and continuing in a dangerous feedback cycle. But if we're going to prevent that from happening, we're going to have to find a way other than reducing methane emissions from wetlands. Global food requirements mean that we can't cut back seriously on rice paddy cultivation, and wetlands are far too important to the environment as groundwater filters and buffers against coastal floods. "I just don't see any way to control methane emissions from wetlands," says Palmer. Instead, we'll need...
