"We're not a city that's adapted well to higher temperatures," Ebi said. "We need to take more action intermediately to adapt."

Heat kills by myriad methods.

People can simply overheat, which can progress, if not treated, to heat stroke, said Jeff Duchin, health officer for Public Health -- Seattle & King County.

Wealth can also be a factor, said Mark Stephan, an associate professor in political science at Washington State University Vancouver.

"Heat waves have a bias in terms of who is affected, partly based on age, but also based on income," he said. "Climate change only exacerbates this, arguably."
