Atmospheric carbon dioxide continued its rapid rise in 2019, with the average for May peaking at 414.7 parts per million (ppm) at NOAA's Mauna Loa Atmospheric Baseline Observatory.

Study finds fossil fuels are main source of carbon in the Arctic

Five years of testing at sites across the Arctic tracked seasonal fluctuations and sources of black carbon, or soot, which contributes to global warming and ice melt.

New step taken towards smart carbon capture

Tokyo - Researchers from Japan have achieved the process of direct electrocatalytic reduction of carbon dioxide. This success raises hopes of developing a process for smart carbon capture.

Mineral weathering and permafrost carbon dioxide release

Alberta - The amount of carbon dioxide released from thawing permafrost might be greater than previously thought because of a process called mineral weathering, according to a new study by University of Alberta ecologists.

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.
