Predictions by climate models are flawed, says MIT meteorology expert
Massachusetts Institute of Technology professor Richard Lindzen, a global warming skeptic, says that too much is being made of climate change by researchers seeking government funding; he said their data and their methods did not support their claims; for thirty years, climate scientists have been “locked into a simple-minded identification of climate with greenhouse-gas level. That climate should be the function of a single parameter (like CO2) has always seemed implausible. Yet an obsessive focus on such an obvious oversimplification has likely set back progress by decades,” Lindzen said

Temperature rise, CO2 follow each other closely
The greatest climate change the world has seen in the last 100,000 years was the transition from the ice age to the warm interglacial period; new research indicates that, contrary to previous opinion, the rise in temperature and the rise in the atmospheric CO2 follow each other closely in terms of time

Per capita CO2 emissions in China reach EU levels
Global emissions of carbon dioxide (CO2) increased by 3 percent last year; an estimated cumulative global total of 420 billion tons of CO2 has been emitted between 2000 and 2011 due to human activities, including deforestation; scientists suggest that in order to limit the rise in average global temperature to 2°C above pre-industrial levels, cumulative CO2 emissions in the period 2000–50 cannot do not exceed 1,000 to 1,500 billion tons

Cutting massive power use at big data companies in a flash
Big data needs big power; the server farms that undergird the Internet run on a vast tide of electricity — Google, for example, uses enough electricity in its data centers to power about 200,000 homes; now, a team of engineers has a solution that could radically cut that power use — a new type of memory in companies’ servers that demands far less energy than the current systems
