Heatwaves hits the USA

http://www.nma.tv The US is going through a prolonged heatwave that has blanketed the eastern half of the country. Although the heatwave hit the South and Mid-west the hardest, the hot weather is moving towards the East Coast in the coming days. As people in the affected areas turn on their air conditioners, the nation's power grid is coming under strain. This summer is a hot one not just for the US, but also in other corners of the globe. Beijing recently hit 105F, nearing records. A Stanford study says heatwaves could become common in the US in the next 30 years due to global warming. But more and more Americans are becoming skeptical.
