Apocalypse Fatigue: Losing
the Public on Climate Change
Even as the climate science becomes more definitive, polls show that public concern in the United States about global warming has been declining. What will it take to rally Americans behind the need to take strong action on cutting carbon emissions?
Pervasive Plastics: Why the U.S.
Needs New and Tighter Controls
Long a ubiquitous part of modern life, plastics are now in everything from diapers to water bottles to cell phones. But given the proven health threats of some plastics — as well as the enormous environmental costs — the time has come for the U.S. to pass a comprehensive plastics control law.
Coping With Climate Change:
Which Societies Will Do Best?
As the world warms, how different societies fare in dealing with rising seas and changing weather patterns will have as much to do with political, social, and economic factors as with a changing climate.
The Greenest Place in the U.S.
May Not Be Where You Think
Green rankings in the U.S. don’t tell the full story about the places where the human footprint is lightest. If you really want the best environmental model, you need to look at the nation’s biggest — and greenest — metropolis: New York City.
The Economic Case for
Slashing Carbon Emissions
Amid a growing call for reducing atmospheric concentrations of CO2 to 350 parts per million, a group of economists maintains that striving to meet that target is a smart investment — and the best insurance policy humanity could buy.
The Other Inconvenient Truth:
The Crisis in Global Land Use
As the international community focuses on climate change as the great challenge of our era, it is ignoring another looming problem — the global crisis in land use. With agricultural practices already causing massive ecological impact, the world must now find new ways to feed its burgeoning population and launch a "Greener" Revolution.
A Timely Reminder of
the Real Limits to Growth
It has been more than 30 years since a groundbreaking book predicted that if growth continued unchecked, the Earth’s ecological systems would be overwhelmed within a century. The latest study from an international team of scientists should serve as an eleventh-hour warning that cannot be ignored.
What Makes Europe
Greener than the U.S.?
The average American produces three times the amount of CO2 emissions as a person in France. A U.S. journalist now living in Europe explains how she learned to love her clothesline and sweating in summer.
Why I Still Oppose
Genetically Modified Crops
Introduced more than a decade ago, genetically modified crops are now planted on millions of acres throughout the world. But the fundamental questions about them remain — both about their safety and their long-term impact on global food security and the environment.
Pumping Up the Grid:
Key Step to Green Energy
The U.S can build all the wind turbines and solar arrays it wants, but until it does something about improving its outmoded electricity grid, renewable energy will never reach its potential. What we need is a new electricity transmission system, with the costs shared by all.
A ‘Dow Jones’ for Climate:
The Case for a Warming Index
If a cap-and-trade bill passes Congress this year, it may include weak emissions targets and will likely need to be strengthened in the years to come. One way to guide future policy: create a Global Climate Change Index that could be used to track global warming’s impacts.
Finding Common Ground on
Protecting Montana Wilderness
In the Yaak Valley of Montana, environmentalists have been talking to loggers, snowmobilers and other longtime opponents of wilderness protection about the future of public lands. Their accord is part of a cooperative effort that could lead to the first wilderness-area designation in the state in a quarter century.
The Folly of ‘Magical Solutions’
for Targeting Carbon Emissions
Setting unattainable emissions targets is not a policy — it’s an act of wishful thinking, argues one political scientist. Instead, governments and society should focus money and attention on workable solutions for improving energy efficiency and de-carbonizing our economies.
A Total Ban on Whaling?
New Studies May Hold the Key
As the International Whaling Commission debates whether to ban all whaling or to expand the limited hunts now underway, recent research has convinced some scientists that the world’s largest mammal should never be hunted again.
A Plea to President Obama:
End Mountaintop Coal Mining
Tighter restrictions on mountaintop removal mining are simply not enough. Instead, a leading climate scientist argues, the Obama administration must prohibit this destructive practice, which is devastating vast stretches of Appalachia.
The Waxman-Markey Bill:
A Good Start or a Non-Starter?
As carbon cap-and-trade legislation works it way through Congress, the environmental community is intensely debating whether the Waxman-Markey bill is the best possible compromise or a fatally flawed initiative. Yale Environment 360 asked 11 prominent people in the environmental and energy fields for their views on this controversial legislation.
The Challenge of Copenhagen:
Bridging the U.S.-China Divide
The United States powered its rise to affluence with fossil fuels, and China resents being told it should not be free to do the same. So as negotiators prepare for crucial climate talks this December, the prospects for reaching agreement remain far from certain.
Learning to Live With Climate Change Will Not Be Enough
A leading environmentalist explains why drastically reducing carbon dioxide emissions now will be easier, cheaper, and more ethical than dealing with runaway climate destabilization later.
The Flawed Logic of
the Cap-and-Trade Debate
Two prominent — and iconoclastic — environmentalists argue that current efforts to tax or cap carbon emissions are doomed to failure and that the answer lies not in making dirty energy expensive but in making clean energy cheap.
Yellowstone’s Grizzly Bears
Face Threats on Two Fronts
The magnificent creature at the heart of the Greater Yellowstone Ecosystem now confronts two grave perils: the loss of its key food source because of rising temperatures, and increased killing by humans. A renowned grizzly expert argues that it’s time to once again protect Yellowstone’s grizzlies under the Endangered Species Act.
Putting a Price on Carbon:
An Emissions Cap or a Tax?
The days of freely dumping greenhouse gases into the atmosphere are coming to an end, but how best to price carbon emissions remains in dispute. As the U.S. Congress debates the issue, Yale Environment 360 asked eight experts to discuss the merits of a cap-and-trade system versus a carbon tax.
To Make Clean Energy Cheaper,
U.S. Needs Bold Research Push
For spurring the transformation to a low-carbon economy, the federal and state governments, universities, and the private sector must join together to create a network of energy research institutes that could speed development of everything from advanced batteries to biofuels.
Consumption Dwarfs Population
as Main Environmental Threat
It's overconsumption, not population growth, that is the fundamental problem: By almost any measure, a small portion of the world's people — those in the affluent, developed world — use up most of the Earth's resources and produce most of its greenhouse gas emissions.
Why I’ll Get Arrested
to Stop the Burning of Coal
On March 2, environmentalist Bill McKibben joined demonstrators who marched on a coal-fired power plant in Washington D.C. In this article for Yale Environment 360, he explains why he was ready to go to jail to protest the continued burning of coal.
On His Bicentennial,
Mr. Darwin’s Questions Endure
Charles Darwin brought an insatiable inquisitiveness to his view of the natural world. On the bicentennial of his birth, author Verlyn Klinkenborg reflects on what Darwin’s most fundamental observations mean to us.
Clinton’s China Visit Opens
Door on Climate Change
Secretary of State Hillary Clinton’s trip to China could be the first step in forging a partnership between the world’s largest emitters of greenhouse gases. A leading China expert sets forth a blueprint for how the U.S. and China can slow global warming – and strengthen their crucial relationship.
What Obama Must Do
on the Road to Copenhagen
If crucial climate negotiations later this year in Copenhagen are to have any chance of success, the U.S. must take the lead. To do that, President Obama needs to act boldly in the coming months.
The Climate Freeloaders: Emerging Nations Need to Act
Key developing countries have long been exempt from efforts to reduce greenhouse gas emissions. Now, as global climate talks move forward, that policy must change.
A Call for Tougher Standards
on Mercury Levels in Fish
In response to industry pressure, the U.S. Food and Drug Administration has failed to set adequate restrictions on mercury levels in fish. Now the Obama administration must move forcefully to tighten those standards and warn the public which fish are less safe to eat.
Moving the U.S. Off Carbon
With Less Pain, More Gain
Many environmentalists assume that putting a price on carbon and creating a renewable energy economy will require major public sacrifice. But the Sierra Club’s Carl Pope argues that a well-designed package of market reforms — not austerity — will lead to a prosperous, low-carbon future.
As Europe Fiddles, U.S. May
Take Lead on Climate Change
Europe’s backpedaling last month on toughening its carbon trading system may have signaled the end of its leadership on climate change. Now, with a new administration and Congress, America appears ready to commit itself to tackling global warming.
A Green Agenda for the
President’s First 100 Days
Environmentalists – from Bill McKibben and Paul Hawken, to Fred Krupp and Frances Beinecke – offer President Obama their advice on the priorities he should set for the first 100 days of his administration.A Green Scorecard for
Stimulating the Economy
In evaluating an economic recovery package, the new U.S. administration and Congress must weigh any proposed spending – on highways or mass transit or wind-power transmission routes – on the basis of clear criteria that would assess just how green the projects will be.
Regulators Are Pushing
Bluefin Tuna to the Brink
The international commission charged with protecting the giant bluefin tuna is once again failing to do its job. Its recent decision to ignore scientists’ recommendations for reducing catch limits may spell doom for this magnificent – and endangered – fish.
Offshore Drilling in Alaska:
Time to Slow the Rush
In the last eight years, vast areas of offshore Alaska have been opened to oil drilling. Now, a conservationist argues, the Obama administration must reverse the Bush-era policies if the state is to avoid irreparable harm to Arctic wildlife and to some of the most biologically productive waters on earth.
President Obama’s Big Climate Challenge
As he assumes the presidency, Barack Obama must make climate-change legislation and investment in green energy top priorities. And he must be ready to take bold — and politically unpopular — action to address global warming.
The Clean Air Act:
Jump-Starting Climate Action
The next U.S. president should not wait for Congress to act on climate-change legislation. Instead, he should make use of the Clean Air Act to begin controlling greenhouse gas emissions and to implement a national cap-and-trade program.
Environmental Failure:
A Case for a New Green Politics
The U.S. environmental movement is failing – by any measure, the state of the earth has never been more dire. What’s needed, a leading environmentalist writes, is a new, inclusive green politics that challenges basic assumptions about consumerism and unlimited growth.
The Corn Ethanol Juggernaut
Oil isn't America's only fuel addiction. Inefficient and environmentally damaging, the corn-ethanol boondoggle will nonetheless be hard to stop.
Solar and Wind Power
Held Hostage – Again
Congress has repeatedly failed to extend the tax credits for renewable energy, which expire at the end of this year. The gridlock is discouraging investment in renewables and jeopardizing major solar and wind projects throughout the country.
The U.S. and China:
Common Ground on Climate
The crackdown on dissent surrounding the Beijing Olympics has been a reminder of China’s lingering authoritarianism. Yet for all our differences, the U.S. and China — the world’s two largest emitters of carbon dioxide — have no choice but to work together to tackle climate change.
Has the Population Bomb Been Defused?
Paul Ehrlich still believes that overpopulation imperils the Earth’s future. But the good news is we are approaching a demographic turning point: Birth rates have been falling dramatically, and population is expected to peak later this century — after that, for the first time in modern history, the world's population should actually start to decline.
Too Many People,
Too Much Consumption
Four decades after his controversial book, The Population Bomb, scientist Paul Ehrlich still believes that overpopulation — now along with overconsumption — is the central environmental crisis facing the world. And, he insists, technological fixes will not save the day.
As Energy Prices Rise,
the Pressure to Drill Builds
President Bush is urging Congress to open the U.S. coasts and the Arctic National Wildlife Refuge to oil and gas drilling. But America must ultimately wean itself off fossil fuels. The question is whether it makes the transition now — or waits until every last one of its unspoiled places has been drilled.
Climate Solutions:
Charting a Bold Course
A cap-and-trade system is not the answer, according to a leading alternative-energy advocate. To really tackle climate change, the United States must revolutionize its entire energy strategy.
The Tipping Point
New evidence suggests that we have already passed a dangerous threshold for the amount of carbon dioxide in the atmosphere – and that the time for taking strong action is slipping away.
The Myth of Clean Coal
The coal industry and its allies are spending more than $60 million to promote the notion that coal is clean. But so far, “clean coal” is little more than an advertising slogan.
States Take the Lead on Climate
With the Bush Administration and Congress failing to act, many states are devising sweeping climate and energy policies that could be a blueprint for a future national climate policy.
The Ethics of Climate Change
When it comes to setting climate change policy, science can only tell us so much. Ultimately, a lead report author for the Intergovernmental Panel on Climate Change writes, it comes down to making judgments about what is fair, equitable, and just.
