...Friday to set in motion the process of regulating greenhouse gases had a little bit of the sardonically threatening spirit of that magazine cover. Concluding a scientific review initially ordered by a two-year-old Supreme Court case, the EPA issued its long-awaited "endangerment finding," formally declaring that carbon dioxide and five other greenhouse gases are pollutants that threaten public health and welfare. Under the Clean Air Act, that finding means that the EPA has a responsibility to address the damage caused by greenhouse gases, possibly through direct regulation of CO2 - just as it regulates other air pollutants, like...
...opportunity to inspire children to consider issues like climate change, Gaglani began work on books about scientific processes. His first book is complete, and he is looking for an illustrator and a publishing company interested in his educational angle. Meanwhile, he is moving forward on a book about the carbon cycle in collaboration with published children’s author Claire A. Nivola.Gaglani stops short of envisioning a career in children’s books, though. “In general, I’m interested in communications. So I can definitely imagine doing this as a hobby...
...Mexico's Yucatan peninsula. (The fossils had been exposed during the construction of a new seaside resort.) Working with his co-authors at Germany's Leibniz Institute of Marine Science, Blanchon calculated the age of the samples by measuring isotopes of thorium in the fossils, a process similar to carbon-dating. The patterns of the fossils indicated points where the coral died when the seas rose too fast for the organisms to adapt; each time the seas stabilized, the corals grew back, but at higher elevations and further inland, a process geologists call backstepping. The result is something like...
...evolutionary biology department, also confirms that hotter temperatures actually suffocate trees in dry times. Piñon pines respond to drought by closing the pores in their needle-like leaves to stop water loss. That keeps them from going thirsty, but it also prevents them from breathing in the carbon dioxide they need to live - and eventually, the drought-stressed trees simply suffocate.

...activity may be a primary factor in climate fluctuations, according to Willie Soon, a researcher affiliated with the Harvard-Smithsonian Center for Astrophysics and the Harvard College Observatory, who offered the hypothesis in an interview with TG Daily, an online news source. Although many climatologists have cited increases in carbon dioxide as the primary cause of the temperature increases associated with global warming, Soon maintained that solar radiation from sunspots also has a great effect. “The sun is a great driving force to climate change,” Soon said in an interview with The Crimson yesterday...
