watch World Climate Report
Scientists from around the world have been meeting in Paris, working out final details of an exhaustive report on climate change and global warming. Now what? VOA's Paul Sisco reports.
Kenneth Denman, an author of the report says, "We're hoping that it will convince people, you know, that climate change is real."
Hundreds of scientists and officials representing more than 100 governments concluded that the burning of fossil fuels and other human activity is responsible for global warming. And it is likely to continue for centuries.
Panel member Susan Soloman says the change is rapid. "You can see this remarkable3 rapid rise that began with the Industrial era. There can be no question that the increases in these gases, these greenhouse gasses are dominate by human activity."
The report makes no policy recommendations but links global warming to rising sea levels, increased drought in some regions and violent storm patterns.
Dr. Achim Steiner directs the United Nations Environmental Program. He says policy makers4 must be committed. "We are also looking for an unequivocal commitment from policy makers, business leaders and civic5 society leaders to take climate change as truly the challenge of our century."
Some delegates wanted policy recommendations in the report, ranging from wider use of renewable energy resources, to development of so-called geo-engineering technologies -- giant mirrors in space, for example, to deflect6 some of the sun's rays.
A University of Arizona researcher, Roger Angel, is exploring the possibility of launching a huge quantity of small plastic discs into orbit, to shield the Earth by diffusing7 a small amount of the sun's radiation. "The effect could be to take our temperature back to pre-industrial levels."
These ideas are very experimental.
Climate scientist Michael MacCracken explains what can be done. "There are a host of things to do. First, many different technologies are cost effective right now, and what we need to do is [use] as many of them as we can, before we get into these geo-engineering technologies.
MacCracken, like most of the scientists at the Paris conference, says the immediate8 focus must be on reducing carbon emissions9, not on looking to outer space for solutions to the global warming problem.
