President Obama's pledge to address climate change was welcomed by the large majority of Americans who care about what kind of planet we leave future generations.

This week he made good on that promise.

The Environmental Protection Agency unveiled an ambitious plan to cut carbon dioxide emissions from power plants by nearly a third by 2030.

It's seen as the centerpiece of Obama's efforts, tackling the biggest culprits behind Earth's warming as well as other pollutants that contribute to health problems.

Not everyone embraced the plan, which has yet to be finalized, but that's no surprise. Some people refuse even to acknowledge we're the cause of the problem, despite overwhelming scientific evidence.

There's no arguing with those who refuse to accept reality.

Thankfully, most Americans recognize what's happening, support action and accept that it won't be easy.

A new Washington Post-ABC News poll released this week found 70 percent back federal limits on greenhouse gas emissions, and 70 percent support requiring states to limit the amount of their emissions.

The support crosses party lines, too — 57 percent of Republicans, 76 percent among independents and 79 percent of Democrats support state limits. Fifty percent support the federal caps.

And if consumers have to pay more for electricity — not necessarily the case because the new rules also aim to increase efficiency — the support remains.


"Asked whether Washington should still go forward with limits if they 'significantly lowered greenhouse gases but raised your monthly energy expenses by 20 dollars a month,' 63 percent of respondents say yes, including 51 percent of Republicans, 64 percent of independents and 71 percent of Democrats," the Post reported.

It's encouraging news.

It shows the United States is no longer willing to bury its head in the sand — and is ready to the lead the global effort necessary to deal with climate change.
