When carbon dioxide is absorbed by the ocean, the water's acid level rises. If this level gets too high, some sea creatures that build protective shells can't grow as fast or even have their shells dissolve, threatening the entire food chain.

Carbon dioxide emissions hit a record high in 2012, but could have been even higher, according to a new report. The increase in emissions was only 1.1 percent in 2012, compared to an average 2.9 percent over the past decade.

Solar panels are most efficient when the sun is beaming down on them at a direct angle, so flat panels are only at their best in the middle of the day. V3 Solar's cone shaped panels solve this problem and also dissipate the extra heat by spinning.
