With the summer solstice now two weeks gone, the northern hemisphere is heating up. High temperatures in some places have made working difficult and have taxed power grids as usage of electricity neared record levels in the U.S. This past weekend, the United States celebrated its 234th birthday on July 4th, with fireworks, parades and many other outdoor activities. Collected here today are a handful of recent photographs of people (and animals) either trying to beat the heat, or just enjoying a sunny summer's day.
