What if the ever-increasing amounts of carbon dioxide that are heating up the atmosphere could be used to produce an abundant supply of liquid fuels? The U.S. government and private labs are pursuing that Holy Grail of renewable energy — but for now the cost of large-scale production is prohibitive.

Systems designed to remove carbon dioxide from the atmosphere will have a “very limited role” in the fight against global warming, according to a new study by the American Physical Society.
While it is technically feasible to pull CO2 from ambient air — as opposed to capturing and
This finding will leave you breathless. A physiology professor at the University of Milan concluded that four men running, walking and riding bicycles emit more carbon dioxide than hybrid cars. He also compared it to gas and diesel cars, which beat the men in terms of carbon emissions.
New research suggests that woodlands, forests and other terrestrial ecosystems are able to sequester up to 40% of the US’s carbon emissions that is caused by burning fossil fuels. The study, which was carried out in the 48 lower states provides evidence that these ecosystems can absorb far more carbon than first thought as long as these regions are not subjected to
Attacks on climate change regulations, thawing permafrost in National Parks, and attempts to cut funding for climate research. Climate change has had some bad news this month. There’s at least one (sort of) bright spot, though: the state of US greenhouse gas emissions. Yesterday, the Environmental Protection Agency
Forecasting what the Earth’s climate might look like a century from now has long presented a huge challenge to climate scientists. But better understanding of the climate system, improved observations of the current climate, and rapidly improving computing power are slowly leading to more reliable methods.
By 2100, CO2 Levels May Reach Concentrations Not Seen in 30 Million Years
written by Yale Environment 360
If industrial carbon dioxide emissions continue unabated, atmospheric concentrations of CO2 could by 2100 reach levels not seen in at least 30 million years, when Earth’s average temperature was 25 to 30 degrees F warmer than today, according to an analysis by a U.S. scientist.

The Chinese government will impose regional emissions targets as part of a national drive to cut the economy’s carbon intensity by 2020, according to a report. While China is studying the potential of a domestic carbon market to achieve its carbon targets, a working group will also be established to develop targets and policies
In many ways the Pacific Northwest United States has become a leader in fighting climate change. From progressive energy efficiency standards that were adopted before most other US states, to joining with California in implementing clean car standards that became the Obama administration’s model for national policy, Washington and Oregon have been
(Reuters) – U.N. climate talks will struggle to agree new greenhouse gas targets next month unless they can solve a complex loophole where developed countries currently ignore emissions from logging plantation forests.
Environment ministers from almost 200 countries will gather in Cancun, Mexico,
It’s called the Greenerator (thanks to my Twitter pal SolarKnowledge for pointing out this one), and it’s the sort of renewable energy device that offers apartment dwellers a way of generating sustainable energy without the attached real estate.
Algae biofuel is something of a dream renewable fuel source: it can thrive on non-agricultural land, use wastewater and absorb carbon dioxide. But development of cost-competitive algae biofuel production will remain a dream for years to come, according to a new report from the Energy
The World Bank’s lending for renewable energy and energy efficiency projects increased by 300 percent between fiscal year 2007 and fiscal year 2010, to a record $3.4 billion. But over that same period, lending to fossil fuel projects also jumped 430 percent.
Canadian chemists are investigating ways that carbon dioxide can be removed and stored from power plants and factories without using the large amounts of energy and water now required in prototype carbon capture systems.
