Sports Illustrated’s current cover says it all.

Green Options reports environmentalists aren’t the only ones talking about global warming anymore: it’s affecting ski resorts, insurance companies, and a host of cultural institutions like the wide world of sports:

The Miami Dolphins have built a climate-controlled bubble to avoid the extreme Florida heat during practices, seven World Cup ski racing events in Europe have been cancelled this season because of warmer temperatures, and Alaska’s Iditarod dogsled race hasn’t started at its traditional location in five years because of lack of snow.

So what is the sport world’s part in fighting global warming?

Make sure stadiums are easily accessible by mass transit and install renewable energy systems (solar or wind) on stadiums are a few ideas. But many professional organizations and athletes are taking action now:

Gillette Stadium in Foxborough, MA has a water filtration and reuse system that collects and recirculates “black” and “gray water” to make the most of all that beer and all those flushes.

Saints safety Steve Gleason runs his Dodge Ram pickup on biodiesel.

The NFL planted 3,000 trees around Florida to try to offset Super Bowl XLI’s estimated one million pounds of carbon dioxide emissions, a main contributor to global warming.

It’s time to launch Einstein’s lock — and the USA’s move to extra daylight saving is worth celebrating — for, according to the BBC:

The US is switching to daylight saving time, or summer time, three weeks earlier than usual to cut fuel consumption and help the environment.

At 0200 EST (0700 GMT) clocks will move forward by an hour, shifting an hour of daylight from morning to evening.

Summer time will last until 4 November, a week later than in previous years.

The extra four weeks are expected to help cut energy consumption, as demand falls for electricity in the evening if it is still light.

The measure was signed into law in two years ago as part of the Energy Policy Act which aims to encourage new energy technologies.

Representatives Edward Markey and Fred Upton, who sponsored the amendment to the original bill, said it was expected to save $4.4bn in energy bills by 2020 and avoid the need to build more than three large electric power plants.

They said it also would save 279 billion cubic feet of natural gas, and avoid nearly 10.8 million metric tons of carbon emissions.

About time.
