THE
NATIONAL debate on climate change has devolved.
From Washington Post, published August 24, 2014.
By
the late 1990s, big U.S. businesses were beginning to accept that greenhouse
gases must be wrung out of the economy. In the 2000s, prominent Republicans
such as Sen. John McCain (Ariz.) and Gov. Mitt Romney (Mass.) proposed
aggressive anti-emissions policies. By 2008, the presidential candidates of both major parties favored strong national climate strategies. Regardless of who won that election, serious action seemed inevitable.
But
Republicans later embraced a strategy of rote opposition to President Obama,
and a faction that rejects the science of global warming dragged the GOP into
irresponsible head-in-the-sand-ism. Democrats, meanwhile, proved unable to
unite around a coherent, comprehensive climate strategy when they controlled
Congress and the White House.
Strong
underlying political currents help to explain Washington’s failure. Voters
generally don’t put climate change high on their priority lists, and there is
evidence that some Americans’ belief in the
science varies with the weather. Party politics often push in a negative direction: GOP primary voters are more likely
to punish a vote for a climate plan than to reward one, while Democrats’ position
in Congress depends on winning races in coal states such as Ohio, Pennsylvania
and West Virginia.
Some
of the Democrats who voted for a large 2009
cap-and-trade bill
lost their seats in the 2010 midterm election. Though that election turned more
on the state of the economy and on health-care reform than it did on climate
change, the voter rebuke recalled the previous Democratic effort to raise the
price of energy: the infamous BTU tax debate, which contributed to the 1994
Republican midterm wave.
So
these days Republicans mostly ignore the issue or offer excuses for doing
nothing: The science is not reliable; anti-emissions policies will harm the
economy; China and India will continue emitting even if the United States cuts
back. Many Democrats and environmental activists, meanwhile, focus on
relatively inconsequential — but potentially winnable — battles, such as their
push to reject the Keystone
XL pipeline .
But there are reasons not to give up. The
biggest is the urgency of action. As the U.S. debate has deteriorated,
scientists’ warnings have become more dire. According to the authoritative Fifth Assessment Report of the
Intergovernmental Panel on Climate Change , every region of the world faces serious risks , including sea-level rise or
worsening heat waves, floods and wildfires — and those are consequences
scientists can predict. Though poor nations along the equator may be hit
hardest, U.S. analysts are beginning to quantify a variety of direct and
negative effects climate change could have in our own country .
These factors help explain
a second reason for hope: Despite ups and downs in the polling, a solid majority of Americans favors action to
curb greenhouse emissions. As with the recent
national shift on gay marriage, feelings on climate change will eventually move
more decisively — we hope in time to spare the world unnecessary expense and
suffering.
And the United States is
reaching a put-up-or-shut-up moment. As Congress dithered, Mr. Obama filled the
policy void with executive actions designed to cut greenhouse emissions under
authorities Congress entrusted to the Environmental Protection Agency decades
ago in the Clean Air Act.
The
EPA’s rules are a decent and, under the circumstances, necessary first step,
but they would not cut emissions enough over the next century. And, for all of
their benefits, they represent a cumbersome and expensive way to slash
emissions. As full implementation looms, industry may press for more efficient
policies that sting companies and consumers less, and Republicans may be
willing to countenance market-based approaches to the climate problem.
All
this explains why, understandable frustrations notwithstanding, the shape of
the climate debate now and through the 2016 election is important. In the
coming days we aim to contribute to that debate with a brief series of
editorials. We will review the need to act; defend the EPA’s efforts but
explain why they are not ideal; highlight several strategies that would work
better; and show why it makes sense for the United States to take steps even
though other nations have yet to do enough on climate change.
Action
of some kind, at some point, is inevitable. Our proposition is that it should
come sooner rather than later and be smart rather than clumsy.
