"The best match for current changes was the Palaeocene-Eocene thermal maximum of 55 million years ago, when vast amounts of methane were released into the atmosphere causing rapid global warming, ocean acidification, and mass extinction. But even then, it took at least 3000 years for ocean pH to drop by 0.5. "That is an order of magnitude slower than today," Hönisch says.

A key point (indirectly pointed to in the article) is that the *rate of change* of acidity is what's critical. We've got the accelerator floored and we're close to the cliff.

+ - Brain Cancer Worries? Look Up Your Phone's SAR->

Submitted by CWmike
CWmike writes: With recent news of a possible link between cell phone radiation and risk of brain cancer, you may have a new-found interest in knowing how much radiation your mobile handset is giving off — or, more importantly, how much your body might be absorbing. The FCC's legal limit for mobile phones is 1.6 Watts of radiofrequency energy per kilogram, using a measure called Specific Absorption Rate (SAR). The Environmental Working Group, which tracks SAR data for more than 1,300 cell phone and smartphone models, notes that several factors besides your handset affect your actual level of exposure. Look up your phone's SAR; or see a full chart of phones.
