Natural gas power plants produce substantial amounts of gases that lead to global warming. Replacing old coal-fired power plants with new natural gas plants could cause climate damage to increase over the next decades, unless their methane leakage rates are very low and the new power plants are very efficient.
A team of researchers working on a Carnegie expedition in Australia’s Great Barrier Reef has documented that coral growth rates have plummeted 40 percent since the mid-1970s. The scientists suggest that ocean acidification may be playing an important role in this perilous slowdown.
In a move that sounds vaguely reminiscent of one of Dr. Evil’s plans, the CIA is planning to investigate how humans could potentially control the global climate.
Sometimes, the best solution to a problem is the easiest one. The real difficulty lies in the application of said solution.
When evaluating the historic contributions made by different countries to the greenhouse gasses found in Earth's atmosphere, calculations generally go back no further than the year 1840.
Could replacing coal-fired electricity plants with generators fueled by natural gas bring global warming to a halt in this century?
Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing the Earth to get hotter and hotter.
It is difficult to measure accurately each nation's contribution of carbon dioxide to the Earth's atmosphere.
Accurately calculating the amount of carbon dioxide emitted in the process of producing and bringing products to our doorsteps is nearly impossible, but still a worthwhile effort, two Carnegie researchers claim in a commentary published online this week by Proceedings of the National Academy of Sciences.
Scientists have known for decades that black carbon aerosols add to global warming.
