Climate Change: El Niño Lends More Confidence to Strong Global Warming <NOBR>Richard A Some scientists have argued from observations that global warming will alter clouds in ways that will largely counter warming by greenhouse gases. But the overwhelming majority of climate scientists sides with the models, which show clouds changing in ways that amplify warming, not dampen it. Whom to believe? To help sort it out, a climate researcher looked at the example of El Niño and La Niña, naturally occurring weather patterns that cause warming (El Niño) and cooling (La Niña) in the tropical Pacific and around the globe. In a report on page _1523_ (http://www.info-aaas.org/l.jsp?d=6890.748281.654.8cAH8W7w42QgXi5scbyBzCg..A) of this week's issue of Science, he analyzes how they have actually influenced clouds and concludes that—at least on the scale of decades—clouds do not counter warming.

Let me know if anyone would like the full text (the link is to the abstract).
Thanks Duane!

When somebody says I don’t believe in global warming, I ask, “Do you believe in evidence? Do you believe in a preponderance of evidence?”
