Carbon dioxide is a heavy hitter when it comes to global climate change. But there are some other big players that contribute to rising temperatures as well including soot and methane. While some scientists have argued to cut these emissions, a new study suggests that targeting these emissions may make much less of an impact than previously thought.

Sequestration of CO2 has been discussed as one way to reduce the impact of burning fossil fuels on climate change by removing CO2 from industrial and power generation emissions and storing it indefinitely underground. This technology has been demonstrated in the laboratory and in pilot studies, but not in large scale tests. That is now changing.
Climate change may be weeding out the bacteria that form the base of the ocean’s food chain, selecting certain strains for survival, according to a new study.
In climate change, as in everything, there are winners and losers. As atmospheric carbon dioxide
Carbon dioxide is the result of burning fuel to make things like cars work. Plants slowly convert that CO2 back to something organic to begin the process again. Working in his lab in the University of Delaware’s Department of Chemistry and Biochemistry, Joel Rosenthal and doctoral student John DiMeglio have developed an inexpensive
By 2025, the official average fuel efficiency of cars in the U.S. will be 54.5 miles per gallon, as established last year with an update of federal efficiency standards known as C.A.F.E. This equates to real-world mileage in the low-40-mpg range—a big jump from today’s average fuel economy around 24 miles per gallon. Despite fears that the increase in
Nobody likes carbon dioxide pollution. So if you are rich enough you send it elsewhere. Just as wealthy nations like the United States are outsourcing their carbon dioxide emissions to China, rich coastal provinces in that country are outsourcing emissions to poorer provinces in the interior, according to UC Irvine climate change researcher Steve Davis and
Global energy-related carbon dioxide emissions increased by 1.4 percent in 2012, a pace that could lead to a temperature increase of as much as 5.3 degrees C (9 degrees F) over pre-industrial times, according to the International Energy Agency’s (IEA) latest World Energy Outlook.
Here’s a lengthy but excellent article from The Atlantic: “What If We Never Run Out of Oil?”
It certainly is an interesting concept – one that I find quite credible. For instance, we have recently discovered untapped reservoirs of methane hydrate (think of it was combustible ice) that collectively is the volume of the Mediterranean Sea.
As atmospheric concentrations of carbon dioxide approach the milestone of 400 parts per million (ppm), a scientist at the Scripps Institution of Oceanography has launched a Website that will publish daily readings of CO2 concentrations, an online resource he hopes will drive home the urgent threat of rising greenhouse gas emissions.
The amount of carbon dioxide in the atmosphere increased by 2.67 parts per million in 2012, marking the second-biggest jump since levels were first recorded in 1959 and decreasing the chances that the planet will avoid a dangerous temperature increase of 3.6 degrees F (2 C) or higher, U.S. scientists say.
Coal is somewhat notorious for not being the cleanest of fuels. Similarly all combustion systems release a good deal of carbon dioxide. A new form of clean coal technology reached an important milestone recently, with the successful operation of a research-scale combustion system at Ohio State University. The technology is now ready for testing at a larger scale.
IKEA has expanded its solar power portfolio with the installation of a new system at its has South Florida store in the city of Sunrise. The installation also marks the 35th completed solar project for the company in the U.S., with four installations at four more locations now in progress.
British researchers have discovered that sea urchins use nickel particles on their exoskeletons to effectively capture CO2 and turn it into a solid form, an intriguing finding that could offer an inexpensive way to capture and store carbon from fossil fuel-fired power plants.
It sounds like magic but it’s actually based on sound science. A British start-up called Air Fuel Synthesis is developing a technology to make gasoline using renewable energy to capture carbon dioxide and water from the air. It then electrolyzes the water to make hydrogen and reacts the carbon dioxide and hydrogen together to make
