The grassroots campaign involved ambassadors from every state, plus D.C. and Puerto Rico.

A few days ago, a fierce army invaded Washington, D.C. to ask our representatives for something very simple: restore our right to breathe clean air.

This modest proposal came from more than 100 “clean air ambassadors” who know the cost of dirty air all too well. Take Hilton Kelley from Port Arthur, Texas, which is home to more than five large refineries, six chemical plants and an incinerator. In his community, one out of every five households has a child suffering from asthma and other contaminated-air-related illnesses. One day, after having moved away from his home town years ago, he looked in the mirror and asked himself, “If I’m not going to do anything about the conditions in Port Arthur, how can I expect anyone else to?”

This month, I had the very good fortune to visit Costa Rica, home to some of greatest biodiversity in the world. In this tiny nation, plants and animals from temperate North America and from tropical South America mingle in habitats at different altitudes (including active volcanoes and rain forests at the beach)! I marveled at hundreds of leaping dolphins, huge rain forest trees with rich canopy life, miraculous birds, sloths and anteaters.

Not surprisingly, Costa Rica is an increasingly popular travel destination, especially for nature-oriented visitors. Of course, rampant tourism can ruin natural landscapes and in so doing, wreak havoc with local communities that depend on those landscapes, which is why early on many Costa Ricans made sustainability a primary focus. The country has been preparing itself for two generations, establishing and protecting national parks and other preserves, training young people as scientists and guides, and developing a sustainable travel ethic. It's a model that Mexico could follow, instead of proceeding on a path of destroying some of its most remarkable ecological treasures for short-term gain.

McCarthy will be a vital player in the effort to protect our families and environment.  (EPA)

This week a Senate committee will hold a nomination hearing for Gina McCarthy to replace Environmental Protection Agency Administrator Lisa Jackson.

Gina McCarthy, the EPA assistant administrator for air and radiation, is a sound choice for the job. Given her background and experience, the Senate should move expeditiously to confirm her.

For more than 25 years Gina McCarthy worked with politicians from both parties, including a stint as Gov. Romney’s energy and climate advisor in Massachusetts. In 2009 Republican and Democratic senators easily confirmed McCarthy by a voice vote to head the clean air division of EPA.

Gina McCarthy is a dedicated environmental professional with a history of working on difficult issues including climate change. We share her vision of an energy-efficient economy which creates sustainable jobs.

Just as clean, renewable energy is lifting off and the impacts of climate disruption become ever more visible, fossil energy production is becoming dramatically more extreme. But extreme fossil energy production is exactly what we don’t need.

In just the last two years, I have seen the Louisiana coast’s oil-slicked marshes after the Deepwater Horizon blow-out, met with Pennsylvanians and Coloradans whose homes are under assault in the fracking boom, toured the Alaskan Arctic with a caribou hunter whose way of life is threatened by onshore and offshore oil development, and shared the outrage of West Virginians whose schools and streams are under siege from mountaintop removal coal mining.

Though these extreme energy projects differ in their methods of extraction, they have two things in common: their massive industrial scale, and how little we know about their potential impacts to our air, water and climate.

Time has run out for the enemies of roadless wilderness. They spent 12 years trying to kill the national law protecting our forests, and yesterday a federal district court said they couldn’t have a minute more—the statute of limitations had run out.

This means you better grab a compass when heading into a national forest because you can get lost amid all the trees saved by this law, known as the Roadless Rule.

Four of the D.C. Circuit Court's 11 seats have been left vacant due to congressional obstruction. (DOJ)

Over the past four years, the federal halls of justice have been left partially hollow as the number of judicial vacancies in the federal courts continues to mount—due to foot-dragging on nominations and partisan filibuster once nominations are made. These vacancies hobble the courts’ ability to do their core work, which includes determining the fate of our most important environmental protections.

Take, for example, President Obama’s nomination of Caitlin Halligan for a seat on the United States Court of Appeals for the D.C. Circuit. In 2010, the president nominated Halligan, praising her “excellence and unwavering integrity,” yet two years later the Senate has twice refused to confirm her to this environmentally critical court. Halligan, a distinguished litigator who has argued five cases in front of the U.S. Supreme Court, is well-qualified for a seat on the D.C. Circuit. Yet despite bipartisan support and several high profile endorsements from law enforcement organizations and leaders, last week Halligan was forced to suffer through a second politically motivated filibuster that Senate GOP’s justified by willfully misrepresenting her record.

Last week, President Obama demanded that Congress take action on climate change, or else he would.

But, after years of political gridlock on the climate issue, coupled with rising seas and worsening droughts, one thing is clear: the nation simply cannot afford to wait any longer to take action. Though Congress may eventually pull together and pass a climate bill, the president must not wait on that uncertain prospect. He must act now.

After all, today the U.S. is farther from enacting a nationwide plan to reduce carbon emissions than it was four years ago. Congress has failed miserably. And though America’s greenhouse gas emissions are beginning to decline, the rate at which they’re doing so is nowhere near what we need to avoid catastrophic climate change.

Reducing black carbon emissions will slow climate change now.

As the environmental ministers of the Arctic nations, including the United States, meet in Sweden next week, they have an opportunity to show leadership on an important though less well-known climate pollutant, black carbon (soot).

While carbon dioxide remains the most important, long-lasting pollutant forcing climate change, recent studies have revealed that short-lived climate forcers like black carbon are equally damaging, especially in the Arctic.

On Monday, President Obama’s inauguration will officially mark the beginning of his second term, and with it his second chance at finally taking strong action on one of the most important issues of our time, climate change.

Two months ago, on the night of his re-election and in front of an audience hopeful to move forward on so many issues, the president brought climate change back to the forefront of the nation’s mind by listing it as a top priority for his second term. Now, President Obama must go beyond the mere mention of the issue and use his bully pulpit to make the connection between carbon pollution and extreme weather. Just as Franklin Delano Roosevelt used his first inaugural address to declare war on the Great Depression, Obama must use his own confirmation to declare war on another societal ill that threatens to destroy life as we know it.

Of course, the president’s rhetoric will mean nothing if it is not backed by concrete actions in the next four years. And the time for action couldn’t be more urgent.

With one Arctic drill rig shipwrecked on an Alaskan island and the other reportedly under criminal investigation for possibly “operating with serious safety and pollution control problems,” oil giant Royal Dutch Shell is doing a pretty thorough job at proving the quest for oil in the pristine waters of America’s Arctic is just too dangerous, too dirty, and too damaging. The week’s events also prove once again that the U.S. Department of Interior should not have approved drilling in the most remote, dangerous place on the planet. It’s past time for the plug to be pulled on this operation.

The cone-shaped drill rig Kulluk sat in 30 to 40 feet of water along the rocky beach of Sitkalidak Island for the entire week and 18 crew members were evacuated by U.S Coast Guard helicopters. A cast of more than 500 salvage experts is working feverishly to stabilize and rescue the rig.  Further, after delays leaving the Arctic Ocean as winter closed in, Shell reported made its decision to move the rig, which does not have a propulsion system and requires towboats to haul it around, from the port of Dutch Harbor south of Alaska to avoid having to pay Alaska state taxes.
