Carbon dioxide News

New method reduces the cost of scrubbing CO2 from the atmosphere

A Harvard professor announced on June 7, 2018, that his company, Carbon Engineering, has found a method to cheaply and directly pull carbon-dioxide pollution out of the atmosphere and turn it into fuel.

Low power CO2 sensor detects building occupants

A new type of sensor to detect carbon dioxide has the ability to indicate whether people are inside buildings to enable smart building management. The sensor is also capable of running off a low level of power.

Freeze-dried foam developed to soak up carbon dioxide

Researchers have developed a novel technology to help address future environmental concerns. This is a macroscale foam that can rapidly soak up carbon dioxide.

Unexpected discovery leads to new strategy for carbon fixation

Scientists in Japan and China announced last week they had discovered an "unexpected" approach to the capture and storage of carbon dioxide away from the atmosphere while working toward the elusive lithium-air battery.

Op-Ed: DOE — 'CO2 not main cause of climate change, it's something else'

U.S. Department of Energy Chief, Rick Perry said on Monday that he does not believe carbon dioxide is contributing to climate change, a statement that is in line with the belief of Environmental Protection Agency's head honcho, Scott Pruitt.

Carbon dioxide peaked at an all-time monthly high in May

With the month of May behind us, we can now say it's official — Global carbon dioxide concentration has set an historic all-time record high for the year, adding to the climate records continually being broken as the Earth warms.

Antarctica not only getting warmer, it's also getting greener

Our perception of Antarctica is beginning to change, especially as the climate continues to warm. The Antarctica we have always seen as a snowy, frigid, and inhospitable place is being transformed dramatically.

Pruitt says CO2 not a 'primary contributor' to climate change

The head of the Environmental Protection Agency (EPA), Scott Pruitt was asked by CNBC Thursday morning whether he thought carbon dioxide was the "primary control knob" for global warming. His answer was in line with climate-deniers in the White House.

New carbon dioxide recycling method aids biofuels

A new method for converting carbon dioxide into carbon monoxide has been developed. This process step could be used to drive efficiencies in biofuel production, as well as aiding with the manufacture of some chemical products.

We have passed a grim CO2 threshold — Possibly for good

Despite the fact that September is usually the month with the lowest levels of carbon dioxide in the atmosphere, this year may go down in the history books as being the first time September failed to register CO2 levels below the 400 ppm threshold.

NASA begins testing of greenhouse gases over eastern U.S.

Hampton - NASA wants to improve on our scientists understanding of the sources of two very powerful greenhouse gases and how they interact in the atmosphere.

Volcanic activity and climate change — What's the connection?

The Earth has gone through a number of changes in climate, from hot to cold, throughout its long history. We know CO2 levels in the Earth's atmosphere play a role in temperature shifts and climate variations, but how does this relate to climate change?

Five fascinating facts you might not know about sea otters

Sea otters tickle our imaginations. Their charming antics make them the clowns of the sea, and for those of us fortunate enough to live alongside them, they are enchanting. The sight of mother otters cuddling young ones make them even more endearing.

Canadian firm opens pilot project to pull carbon from air

A Canadian startup has started a pilot project to take CO2 out of the atmosphere in the form of pellets. The company plans to scale it to a global scale enabling countries to suck more CO2 from the atmosphere than they dump in.

Why is so much carbon dioxide produced from streams?

Stockholm - Running water is a contributor to carbon dioxide. However, precisely why rivers and streams send so much of the gas into the atmosphere has confused scientists. A new study sheds some light.

Scientists: Stop burning fossil fuels, there is no C02 technofix

If we are to limit climate change, an immediate end to burning fossil fuels is necessary, scientists in Germany reported in a recent study.

Unused mobile phones are wasting £100 million of gold says report

A study has found that over £100 million worth of gold is being wasted inside unused or broken mobile phones in the UK alone. It suggests that mobile operators should be doing much more to encourage the recycling of old devices.

Global carbon dioxide levels hit new record

Global carbon dioxide concentrations have hit a new monthly record, reaching 400 parts per million, according to the latest data on atmospheric pollution.

Changing temperatures could lead to awakening permafrost

Scientists are worried that as the Arctic warms through global warming, then the considerable quantity of carbon locked away in Arctic tundra will be transformed into greenhouse gases (carbon dioxide and methane).

Scientists now able to transform sun's energy into liquid fuel

Renewal energy had its own shining star when in 2011, Daniel Nocera invented the artificial leaf. By harnessing the sun's energy using silicon, he was able to split water molecules. He theorized that it was possible to create a liquid fuel.

Carbon release contributed to end of last Ice Age

Southampton - Carbon dioxide released from the ocean deeps contributed to ending the last Ice Age, it’s emerged from a new study led by the UK's University of Southampton.

Are sharks adapting to the acidic oceans?

Some species of shark are at risk from rising levels of acidity in the oceans. To avoid the risks that high levels of carbon dioxide pose, the epaulette shark appears to have adapted physiologically.

New report shows greenhouse gases at unprecedented levels

Surging levels of carbon dioxide around the world have caused greenhouse gases in the atmosphere to reach unprecedented levels. The World Meteorological Organization's annual Greenhouse Gas Bulletin shows GHG concentrations rose 34 percent since 1990.

NASA successfully launches a carbon monitoring satellite

NASA tried a second time to launch a satellite into orbit to study how the earth absorbs carbon dioxide, which has increased over time and has been the primary cause of global warming.

Carbon dioxide hits record level

Geneva - Carbon dioxide levels have hit a landmark in the Northern Hemisphere. Half the world has seen a full month at or above the symbolic 400 parts per million (ppm) CO2 level.

CO2 hits 400 parts per million

Geneva - The World Meteorological Association announced Monday that the average monthly concentration of carbon dioxide (CO2) in the northern hemisphere exceeded 400 ppm in April, the highest monthly average on record. Scientists say 'time is running out'

Experts say global warming will make food less nutritious

With unprecedented global warming occurring worldwide, there are more than enough problems to go around. Now, evidence suggests there’s another unpleasant change that we will likely have to deal with.

Rising carbon dioxide lowers crop nutrients

Botanists have shown that plants grown in higher concentrations of carbon dioxide have greater yields, but lower amounts of essential nutrients.

Study finds excessive CO2 makes ocean fish fearless

A joint Australian and American research team has found fish exposed to high levels of carbon dioxide experience a change in behavior, making them bolder. Instead of fleeing from predators, they seem to be attracted to them.

Why are mosquitoes attracted to people?

Female mosquitoes, which can transmit deadly diseases like malaria, dengue fever, West Nile virus and filariasis, are attracted to people by smelling the carbon dioxide we exhale. This is the outcome of a new study.
