Amnesty International may be best known to American audiences for bringing to light horror stories abroad such as the disappearance of political activists in Argentina or the abysmal conditions inside South African prisons under apartheid. But in a new report on pregnancy and childbirth care in the U.S., Amnesty details the maternal-health care crisis in this country as part of a systemic violation of women's rights...
...Senate hearing last June, Environmental Protection Administration (EPA) official Randy Pomponio, said that the extent of damage is not yet known: "We are just beginning to understand and assign value to these ecological services...
...because, as the authors freely admit, it isn't: climate science continues to evolve as new evidence comes in. Indeed, back in 2006, even before the latest IPCC report was complete, researchers in Britain were already planning to launch an update. Helmed by the U.K.'s Met Office (formerly known as the Meteorological Office), the update, published March 5 in the journal Wiley Interdisciplinary Reviews: Climate Change, is based on more than 100 peer-reviewed post-IPCC studies. The new data may shift the evidence for climate change, but none of it weakens what the IPCC said three years...
...scenarios, including those in which humans do not emit any greenhouses at all. "We go out of our way to check out other explanations - by assuming it's all explained by solar activity, or by solar activity plus volcanoes, or by combinations of any of the other natural forcings known to affect climate," says Hegerl...
According to the models, none of those combinations can produce the climate patterns currently being observed in the real world. Add the greenhouse gases that we know humans are generating (and which we've known since the 1800s tend to warm the Earth, all other things being equal), and the simulations finally come close to matching the real world. Its possible, albeit far-fetched, that the simulations are defective. It is even less possible that all of them (and there are many) are defective in the direction of overstating humanity's contribution to warming...
