Climate Changes

Posted by: Kory Raftery

Several stories on the science and politics of global warming caught our attention this week:

A white roof may look like a painted masterpiece to those who want to reduce urban heat. The National Center for Atmospheric Research recently completed a study demonstrating that white roofs can be an effective method for cooling. The study’s simulations provide an idealized view of different types of cities around the world and indicate that, if every roof were entirely painted white, the urban heat island effect could be reduced by 33 percent.

According to a new report released by a leading Canadian environmental group, the city of Vancouver, which will host the 2010 Olympic Winter Games, would earn a bronze medal if fighting climate change were an Olympic sport. The report claims the event’s organizers have done a good job building energy efficient venues, but have fallen a tad short when it comes to offsetting carbon emissions surrounding the Winter Games. Environment is one of the three “official pillars” of the Olympic movement.

Just before athletes from around the world will have a chance to earn their gold, silver and bronze medals, athletes from Indianapolis and New Orleans will go after the Vince Lombardi trophy. And it is estimated that this year’s Super Bowl – which the NFL says is more environmentally responsible than in the past – will produce 310,000 pounds of carbon emissions. In addition, researchers claim the stadium in Miami will use 187,000 KW of electricity and the television sets of home viewers will consume roughly 10,004,603 KW of energy. And speaking of green, it is estimated that close to 54 million pounds of avocados will be consumed by guacamole loving fans.
