The White House is planning to establish a new climate panel, headed by a well-known climate denier, to question the findings of the president's own intelligence agencies that climate change does indeed pose a national security risk.

Long considered unfeasible, direct-air capture of carbon dioxide has been achieved by a set of entrepreneurs. Scaled up, the expensive technology could slow climate change.

Even if carbon emissions are reaching a "plateau," that still represents an unprecedented amount of the gas entering the atmosphere every year.

For the first time, electricity generated from burning natural gas will surpass coal, largely due to fracking of shale. While that means that carbon dioxide emissions will continue to drop, it also means that methane emissions will increase.

The last time carbon dioxide levels were this high was a million years ago. The global community needs to reduce emissions by 80 percent to stop the increase in CO2 levels. The data was reported by the National Oceanic and Atmospheric Administration.

The fossil fuel industry has convinced the public that aggressive carbon reduction will harm the economy. Au contraire. The carbon reduction leader will secure its place at the top of the global economy, argues UrbDeZine Editor Bill Adams.

President Barack Obama hopes to add to his "climate legacy" by having the EPA adopt the nation's first regulations to reduce methane emissions, the second most prevalent greenhouse gas emission after carbon dioxide, but far more powerful.

Yes, one is with and the other without oxygen, and both divert waste from the landfill—but in terms of the end products, what is the advantage of anaerobic digestion? Simply put, does society face a shortage of compost or renewable energy?

After years of declining carbon-dioxide emissions in the U.S., and growing hope in the country's ability to meet President Obama's emission reduction targets, preliminary data indicates emissions from energy sources increased 2% last year

Even as the world (unsuccessfully) tries to formulate a treaty to get nations to reduce their carbon emissions, researchers indicate it may be too late - the tipping point may have been reached. But what if CO2 could be extracted from the air?

A new study produced by an international team of scientists focuses on efforts to reduce the production of two shorter-term pollutants, rather than carbon dioxide, that drive climate change.

Carbon dioxide is one of the most widespread greenhouse gases produced by humans. Trees can absorb it, but release it when they die. Scientists are looking to build artificial trees to do the job permanently.

New research suggests that huge domes of carbon dioxide hover over urban areas, which is prompting some scientists and policymakers to stress the importance of cities as the frontlines of the war on greenhouse gas emissions.
