When it's hot outside, city neighborhoods with lots of pavement get hotter and more polluted than the ones with more greenery. It's called the urban heat island effect. And as the summers in the Northwest get hotter with climate change, these hot spots pose a growing risk to human health.In Portland, researchers are mapping the city's hottest, dirtiest places, and looking for ways to cool them down.

The hot weather, along with the cool rivers and ocean, can be a deadly combination in the Northwest.  The near-drowning of a child in Oregon is a good reminder to practice water safety.

On Monday, an 8-year-old boy was swimming in Butte Creek in Scotts Mills Park. Marion County Sheriff Sergeant Chris Baldridge says the older brother and aunt were also in the water.
