Armed with vivid images from space and remote sensing data, scientists, environmentalists, and armchair conservationists are now tracking threats to the planet and making the information available to anyone with an Internet connection.

For nearly a decade, The New Yorker’s Elizabeth Kolbert has been reporting on climate change. In an interview with Yale Environment 360, she talked about the responsibility of both the media and scientists to better inform the public about the realities of a warming world.

Aided by new access to remote regions, researchers have been discovering new species at a record pace — 16,969 in 2006 alone. The challenge now is to preserve threatened ecosystems before these species, and others yet unknown, are lost.

The number of vehicles worldwide is expected to reach two billion in the next two decades. Surprisingly, China where the demand for cars has been skyrocketing just may offer the best hope of creating a new, greener transportation model.

Yale University’s recently opened Kroon Hall is a state-of-the-art model of where the green building movement is headed. Yet even this showcase for renewable energy highlights the difficulties of creating a building that is 100 percent carbon neutral.

Led by China, the developing world is engaged in a flurry of dam construction, touting hydropower as renewable energy in an era of global warming. But critics point out that the human and environmental costs of dams remain high.

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.

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.

Issued less than two years ago, the report from the Intergovernmental Panel on Climate Change was a voluminous and impressive document. Yet key portions of the report are already out of date, as evidence shows the impacts of warming intensifying from the Arctic to Antarctica.

NASA’s Robert Bindschadler, a leading expert on glaciers and ice sheets, is part of an international team monitoring a large and fast-moving glacier in West Antarctica. In an interview with Yale Environment 360, he explains the dramatic impact this unstable mass of ice could have on global sea levels.

In the last few decades, urban sprawl, once regarded as largely a U.S. phenomenon, has spread across Europe. Now an emerging group of planners is promoting a new kind of development — mixed-use, low-carbon communities that are pedestrian-friendly and mass-transit-oriented.

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.

In a bold departure from past U.S. policies, President Barack Obama sees clean energy and “green jobs” as critical components of an economic stimulus strategy.

Even as they debut the next generation of hybrids and battery-powered cars, auto company executives are not confident that the American public will buy them.

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.

Geologist Yong Yang has serious concerns about plans for a massive Yangtze River diversion project. When he went public with them, he found out how difficult it can be to challenge a government decision in China. The third in a series on Chinese environmentalists.

Although he finds the possibility unsettling, Canadian climate scientist David Keith believes large-scale geoengineering will eventually be deployed to offset global warming. In an interview with Yale Environment 360, Keith explains why scientists must begin researching an “emergency response strategy” for cooling an overheated planet.

A number of companies, including one headed by biologist and entrepreneur Craig Venter, are developing genetically engineered biofuels that they say will provide a greener alternative to oil. But some environmentalists are far from convinced.

The potential for electric vehicles has been talked about for decades. But a former Israeli software entrepreneur is developing a game-changing infrastructure that could finally make them feasible — a standardized network of charging stations where drivers can plug right in.

Gary Yohe is spending a lot of time these days studying the economic issues surrounding climate change. In an interview with Yale Environment 360, the Wesleyan University economist talked about why the world needs to start taking steps to adapt to climate change and why strong action must be taken despite uncertainty about the extent of the warming and its ultimate effects.

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.
