What Can Volcanoes Teach Us About Climate Change?
In an attempt to predict how massively elevated carbon dioxide levels will affect life on Earth, scientists are turning to volcanoes.
Carbon Dioxide
Humans Are Producing Too Much Carbon Dioxide for Forests to Absorb
A recent study shows that, while intact forests are playing a large role in absorbing CO2, it's only a fraction of the amount human activity creates.
Tropical Deforestation Is the Third-Biggest Carbon Emitter in the World
According to a new analysis, tropical forest loss currently accounts for 8 percent of the world's annual carbon dioxide emissions.
A New Landmark Agreement Will Halve Shipping Emissions by 2050
The global shipping industry will still need to ratchet up its efforts to decarbonize to keep the goals of the Paris Agreement alive.
Tropical Countries Have Five Years to Cut Carbon Emissions From Deforestation by Half
But a new study finds that the ambitious goal of halving emissions from forest loss in the tropics by the end of the decade remains within reach.
Airlines Can Cut Greenhouse Gases and Save Money
A new study highlights how American air carriers can cut emissions and improve their bottom lines at the same time.
The Perfect Swarm
How the epic quest to find protein revealed a surprising link between climate change and obesity.
The High Cost of Thawing Permafrost
A new study finds even more reason to fight global warming.
When's the Last Time Our CO2 Levels Were This High?
Global atmospheric CO2 is now above 400 ppm. That's uncharted territory for humans—but not for Earth.
Can a Simple Rock Reverse Global Warming?
Among the natural substances that absorb carbon dioxide is olivine, a magnesium-containing crystal found in igneous rocks.
Urban Growth Is Still a Problem for Climate Change
The biggest cities may have inspired all the panic, but it's the small and mid-sized cities that are going to produce the most carbon dioxide in years to come.
Companies Learn the Value of Being a Step Ahead of the Law
Doing well by doing good is a common mantra in business circles. A new examination of a voluntary carbon-limiting exchange finds the businesses benefited most when the market believed they were anticipating inevitable regulations.
Climate Change: A Moment of Species Pride
An astrophysicist surveys Miller-McCune’s carbon footprint graphic from a post-Durban climate change vantage and wonders if the U.S. and the world can’t do a better job of stepping up to the challenge of climate control.
Germany's Road to Natural Gas Has Coal Detour
Germany's energy revolution makes a shift to natural gas likely all over Europe.
Teaching Sustainability Has Benefits for Big Business
Companies ranging from banks and defense contractors to organic yogurt makers reap benefits by creating a corps of sustainable-savvy employees.
Northwest City Scores with Transportation Demand Management
Although lots of places in the United States sample bits and pieces of transportation management, Bellingham, Wash., shows what can happen by taking on the full program.
Social Cost of Carbon Has Wide-Ranging Impact
A requirement for cost/benefit analyses of federal rules has created — without any real public input — a very important number in deciding what to do about greenhouse gases.
Albedo Loss Double that Predicted
The loss of sea ice is a concern for more than polar bears, as the loss of reflectivity it represents means the planet may warm even faster.
Tracking Climate Change -- Comparing Total and Per Capita CO2 Emissions
A footprint comparison of total carbon dioxide emissions by nation and per capita shows there's plenty of room for smaller countries to reduce their carbon footprints.
Trees Helped Make this Planet Heaven on Earth
Two planets diverged in a solar system, and the successful one took a path more wooded.
The Dirt on Climate Change
Could soil engineered specifically to maximize carbon storage dampen some effects of climate change? Very possibly.
Vulcan Logic and the Missing Sink
Researchers studying a mashup of existing data are tracking exactly where carbon is entering — and exiting — the atmosphere.
'Deforest Fires' Fan Global Warming
Deforestation has long been associated with global warming, but a new paper suggests the method of deforesting — intentionally burning — may be a terrifically potent climate changer, too.
