(InfoWorld) - In a Silicon Valley speech urging businesses to push clean technology, environmentalist and former U.S. Vice President Al Gore said the United Nations report on climate change released Friday makes it a near certainty that global warming is real and needs to be addressed immediately. "The degree of certainty, which was already very high, is now as close to certain as scientists are ever willing to say something is certain," Gore said in an address to Silicon Valley business and community leaders in San Jose, California. The International Panel on Climate Change's fourth report on the subject since 1990 says human activity, including the burning of fossil fuels, is the primary cause of global warming. Gore implored his audience of 1,500, many of them executives and employees of technology companies in Silicon Valley, to use their collective knowledge and resources to promote green technology that causes less pollution and can reverse the effects of climate change. "The world faces an unprecedented challenge, and Silicon Valley can make an unprecedented contribution to meeting that challenge," Gore told them. "You can chart a course and change the future of civilization." Technology companies recently have been focusing more on green technology, such as designing computer processors that generate less heat, building systems that better manage electricity use in data centers, improving manufacturing processes, and recycling old computers. Gore urged them to do more. He criticized the George Bush administration's reaction to the U.N. report, which was to restate President George Bush's opposition to mandatory reductions in greenhouse emissions. "It's not as if the oil lobby has too much influence in the White House. The problem is the oil lobby is the White House," he said. Gore also describe as "unethical" a lobbying tactic by oil companies and other critics of climate change to pay $10,000 for each scientific paper produced that disputes the potential harm of global warming. "(Gore's speech) was a stirring challenge," said Russell Hancock, chief executive officer of Joint Venture Silicon Valley Network, which hosted the event. "We need to organize and mobilize so that Silicon Valley can keep doing the kind of innovation that made us famous." Chip maker Cypress Semiconductor incubated a startup that makes solar power systems, said Eric Benhamou, chairman of Cypress. SunPower is now a standalone company. "I think we are a unique center of technology innovation in Silicon Valley, and I think we have the best research universities relevant to the climate protection challenge," said Benhamou.

Global warming has had little noticeable impact in Washington, D.C. Politicians in the nation's capital have been reluctant to set limits on the carbon dioxide pollution that is expected to warm the planet by 4 to 7 degrees Fahrenheit during the next century, citing uncertainty about the severity of the threat.

Climate change is in the news again, with the Senate having held hearings and the Intergovernmental Panel on Climate Change having issued its fourth five-year report in Paris.  It makes us wonder whether more worrywarts will be propelled by guilt into buying absolution.
