Climate change deaths in Japan, noted

Nearly a year ago, I posted about the regularity of record summer rainfalls in Japan causing death and destruction. 

This year's record rainfall story seems particularly bad:

The Japan Meteorological Agency reported on Saturday that rainfall in many of the affected areas had reached record levels — with some areas reporting rain two or three times as high as the monthly average for all of July over just five days.

“This is a record high rainfall which we never experienced,” Prime Minister Shinzo Abe said in a Saturday morning ministers’ meeting, urging his cabinet to take “every measure to prevent the disaster from worsening by taking advance actions.”

It's affecting some famous cities, too (Hiroshima and Kyoto):

By Saturday evening, at least 51 people were dead and 48 were missing, according to the public broadcaster NHK. More than one million people in 18 districts had been ordered to evacuate their homes and 3.5 million had been urged to leave.

The infrastructure damage in that country is hardly likely to be able to explained away as being caused by new development - it's not as if it's a booming population expanding out into the countryside.  Quite the opposite.

I would also like to know how the economists and their rubbery calculations of "up to temperature increase X, benefits of warming outweigh damage" manage to figure in the loss of life and infrastructure from floods.  

Climate change is real and causing deaths now.
