(Newser) – A third person has died as floods continue to ravage northern Colorado, driving some 4,000 people out of Boulder late yesterday. Rainfall in the city has obliterated a 73-year record, with 12.3 inches falling since Sept. 1—compared to 5.5 in September 1940. Floodwater is pouring from neighboring Boulder Canyon, Reuters reports. "There's so much water coming out of the canyon, it has to go somewhere, and unfortunately it's coming into the city," says an official. The Denver Post shares these jarring numbers: Boulder Creek typically flows at between 100 and 300 cubic feet per second; it hit 4,500 cfs this week.

Further, a rep for the US Geological Survey says there was just a 1% chance Boulder would see a storm like this in a year, "meaning the storm is a proverbial 100-year flood," writes the Post. Nearby Longmont has seen 7,000 evacuated, while the National Guard brought supplies to the town of Lyons, which has been cut off from neighboring areas. Landlines and cellphones aren't working in Estes Park, where the only functioning way to communicate with the outside world is via ham radio. With rain likely to continue today, President Obama declared a state of emergency for the state last night, CNN reports.

My name is Noah and I'm building a big boat. The Lord has spoken to me and all the climate change deniers are going to have to repent tomorrow, on Yom Kippur (Day of Atonement), or learn very quickly how to tread water for 40 days and 40 nights! Nighty night!

check out these global humidity graphs (taken from three separate studies) if you don't think there's a reason for more floods happening: the science here is simple. more heat is getting trapped in the atmosphere due to more CO2 being released, and so oceans and lakes evaporate more moisture into the atmosphere, which results in more intense flooding.
