...February that was surprising only in its utter lack of hedging. "Warming of the climate system is unequivocal," the report stated. What's more, there is "very high confidence" that human activities since 1750 have played a significant role by overloading the atmosphere with carbon dioxide hence retaining solar heat that would otherwise radiate away. The report concludes that while the long-term solution is to reduce the levels of CO2 in the atmosphere, for now we're going to have to dig in and prepare, building better levees, moving to higher ground, abandoning vulnerable floodplains altogether. When former Vice...
...choking on greenhouse gases, it's not hard to see why. Global carbon dioxide output last year approached a staggering 32 billion tons, with about 25% of that coming from the U.S. Turning off the carbon spigot is the first step, and many of the solutions are familiar: windmills, solar panels, nuclear plants. All three technologies are part of the energy mix, although each has its issues, including noise from windmills and radioactive waste from nukes...
When a business with more than 7,000 stores, 1.8 million employees and $345 billion in sales changes its ways, it's hard not to notice. Wal-Mart has made itself the darling of greens with its pledge to install solar panels on many of its stores, switch to hybrid vehicles, conserve water and even buy wild-caught salmon. More important, its mandates are having an incalculable ripple effect through its 60,000 suppliers, which are being asked to join Wal-Mart's effort to reduce packaging, waste and energy use. And when Wal-Mart asks, there's little question...
...bankroll the installation of more efficient equipment in factories. Barbara Finamore of the China Clean Energy Program estimates that this could eliminate the need for 3,000 new power plants over the next few decades. China also imposes higher taxes on large cars than on small ones; subsidizes wind, solar and other renewables; and has passed a law that aims to make 15% of the country's power come from renewables...
India is further behind China in developing renewable-energy sources, but the need for power is spurring innovation. India has an aggressive solar and wind industry, with one company, Suzlon, generating $1.5 billion in wind-turbine revenue in 2006. But India, with its less-developed economy, cannot as easily afford the cost of going green--or at least greener. "The Indian government has not taken the problem seriously," says Steve Sawyer, a policy adviser for Greenpeace International...
