Chromium plating facilities emit high levels of the carcinogen into local communities.  (Neal Sanche)

Chromium shows up in surprising places in modern society—most notably on car bumpers and furniture to improve how they look. Too often, the facilities that do this kind of plating put the carcinogen hexavalent chromium into the air in local communities where they operate.

The highly toxic chemical was made infamous by Erin Brockovich’s work on a California case where hexavalent chromium leaked into a town’s drinking water. The case resulted in action against Pacific Gas and Electric Company, which settled for several hundred million dollars. Yet that case has hardly been the only incident, or the only way, that hexavalent chromium from these facilities can affect people’s health.

Life doesn’t hand you many second chances to make good on promises.

But that’s what the American public, with an assist from superstorm Sandy, has given President Obama: another 4-year opportunity to tackle climate change—the critical environmental issue of our time. He’s now talking about the issue again, after two years of near-silence, and just a few days ago spoke of “an agenda that says we can create jobs, advance growth and make a serious dent in climate change.”

President Obama's words aren't quite as bold as those he made four years ago about attacking climate change, but they give us hope that climate change has become a politically viable issue—especially when seen in the context of the election.

Denver smog. Brought to you in part by fracking.

Last week, supporters of the controversial drilling practice know as fracking held a rally in Denver. According to media reports, one booster drew laughs from the crowd when he said that fracking’s economic benefits would eventually "trickle down to attorneys [and] doctors."

Colorado doctors are probably already seeing increased business because of fracking, but not in a humorous way.

While for many in the country, thoughts of Hurricane Sandy are being replaced by thoughts of the election, football, or the Thanksgiving holiday, for the tens of thousands of people in New York and New Jersey, survival and their families' well-being are still the urgent thoughts.

Two weeks after the storm, more than 68,000 people in the path of superstorm Sandy were still without power. Eighty-five died during Sandy and many are still suffering from the total loss of their homes and belongings, lack of food, heat, clothes, gas and more. At the worst point, the Long Island Power Authority reported that 8.5 million homes and businesses in the region were powerless. Gas rationing took over in the New York city area, and a blustery, snowy nor’easter storm left many shivering to stay warm without heat.

The tremendous costs of Sandy are still growing. New York Governor Andrew Cuomo estimated that Sandy will cost the state of New York $33 billion. New Jersey’s best estimates approach $50 billion. All combined, Sandy was the second most costly storm in U.S. history, just behind Katrina. The area affected by Sandy produces fully one-fifth of our nation’s GDP, so the economic implications of this storm have yet to be fully realized. It’s clearly in our entire nation’s best interest to do everything we can to get this region up and running and back to business as quickly as possible.

To deny that Sandy was intensified because of climate change would be to deny science. Rising ocean temperatures and sea levels make storms like Sandy more powerful and disastrous.
