... what has a melting glacier in Argentina  to do with hanging laundry outdoors in Florida?

Quite a bit.

An common sight in Europe (sometimes even a tourist attraction), hanging laundry in your back yard is  not allowed in parts of America. Many communities,  gated, private, otherwise, have specific rules against it. It pushes down property prices. Or that's what they believe - clotheslines make a neighborhood look poor. But since everybody uses a dryer instead, by NOT hanging your washing you are producing a lot of CO2.

In fact, writes Alexander P. Lee from the Project Laundry List,

the tumble dryer is the second largest energy-consuming appliance...There is no such sense as an Energy Star dryer; these machines are inherently inefficient, using natural gas or electricity to heat air.

Some Americans start to question these community rules and  try to change it,  writes the New York Times.

Should Americans have the right to hang their laundry outdoors, even if many of their neighbors oppose it and community rules ban clotheslines as unsightly threats to property values? Legislators in Colorado, Hawaii, Maine and Vermont have prohibited anti-clothesline rules, and similar action is being considered in several other states.

If the rules are changed, it would be inefficient, energy-wasting suburbia that could help prevent emissions. And yes, laundry will smell a lot nicer.
