Global Warming Threatens Resource-Poor Africa
U.N. officials said last week that Africa is especially vulnerable to the harmful effects of global warming and lacks the resources to deal with them. They said industrialized nations should not look to developing nations to reduce greenhouse gas emissions without doing more themselves.
Meanwhile, the U.S. National Academy of Sciences joined with other such scientific groups in a dozen nations in calling on world leaders to limit the threat of climate change by decreasing their dependence on fossil fuels.
And the authors of an article in American Scientist magazine looked at the ecological effects of climate change on the Antarctic Peninsula. They say the average midwinter temperature there has increased by 6 degrees Celsius since 1950, or five times the global average.
American companies that burn coal to make electricity are looking for a way to build plants that would capture their emissions, a strategy that may become a lot more important soon, according to the New York Times.
And, finally, the Christian Science Monitor began a series called "Empty Oceans" that looks at disappearing fish stocks and changing undersea ecosystems, among other factors that are raising alarms.

PODCAST & VIDEO: Engineering Around Extreme Events
Extreme events, such as super floods and hurricanes, are becoming more common, so civil engineers are trying to adapt civil infrastructure such as bridges to these unpredictable and sometimes devastating meteorological events. Engineer Ana Barros discusses how engineering can prepare us for extreme weather events, but also how changing climate and population conditions can affect the ability of infrastructure to hold up over time.
