The Biggest Climate Migration Problem May Be that There’s Not Enough of It 0126.rtfThe Coming Catastrophe?What if We're on a Much Worse Climate Trajectory than We Realize? 1225.rtf - - This article / opinion begins "What if we really are heading for a +5° hotter world after all? "2 mechanisms determine the planet’s temperature trajectory: the greenhouse effect and planetary albedo. We have a pretty good handle on the 1st, but the 2nd remains a muddle and a wildcard. "One very senior scientist in particular - Columbia University’s James E. Hansen - keeps warning us that mainstream science is getting albedo badly wrong. If he’s right, we’re in for a much bumpier climate ride than we realize. "Changes in albedo — the proportion of the sun’s energy that gets reflected back out into space, rather than absorbed by the Earth — turn out to be tricky to model. The way clouds interact with aerosols, in particular, continues to stump scientists: it’s the biggest source of uncertainty in the IPCC’s estimates. "Hansen argues that some types of pollution make clouds much brighter, and albedo much stronger, with the unfortunate and paradoxical effect that cleaning it up accelerates global warming. If he’s right, we’re facing 4 or 5° of warming, not 2 or 3°. And that’s a much, much more unstable atmosphere. "It would be nice to be able to dismiss Hansen as some sort of crank, but he certainly isn’t that. Hansen is one of the world’s most highly regarded climate scientists. He’s the guy whose 1988 Congressional testimony first brought concentrated attention to global warming as an issue of political significance.... "If James Hansen is right, we’re in big big trouble. Way bigger trouble than we realized. If James Hansen is right, the most serious climate impacts could start piling up within just a decade or 2, not deep into the 22nd century as standard climate models suggest. If James Hansen is right, we need to get over our shit and understand we’ve been unwittingly managing solar radiation for half a century, and have only recently stopped doing it, leading to a kind of undiagnosed termination shock from the cessation of an unintended spell of geo-engineering. If James Hansen is right, the case for dramatic interventions to curb the worst impacts of climate change is much stronger than we’d realized."100s Killed as Floods Ravage North Pakistan 0825.rtfAs Climate Disasters Kill in Pakistan, the True Scale Is Unknown 0525.rtfSunbelt’s Growing Population Faces Increasing Climate Hazards 1224.rtfWeather Extremes Influence Illegal US-Mexico Migration and Return 1124.rtfDozens Killed in Spain Floods 1024.rtfHow Climate Disasters Are Making Mobile Homes a Huge Risk 1024.rtfCompany Losing Money to Climate Change?
