Study: More CO2 Will Have Little To No Impact On Global Warming

Precision research by physicists William Happer and William van Wijngaarden has determined that the present levels of atmospheric carbon dioxide and water vapor are almost completely saturated. In radiation physics, the technical term “saturated” implies that adding more molecules will…

A new material for separating CO2 from industrial waste gases, natural gas, or biogas

With a new material, the greenhouse gas carbon dioxide (CO2) can be specifically separated from industrial waste gases, natural gas, or biogas, and thereby made available for recycling. The separation process is both energy efficient and cost-effective.

75 ways Trump made America dirtier and the planet warmer

“I want crystal clean water and air.” That’s what Donald Trump said in the first chaotic presidential debate with Joe Biden. But there is scant evidence of that desire in the actions of his administration, which has spent nearly four…

Arctic Ocean sediments reveal permafrost thawing during past climate warming

Sea floor sediments of the Arctic Ocean can reveal how permafrost responds to climate warming. Researchers have found evidence of past permafrost thawing during climate warming events at the end of the last ice age. Their findings caution about what could happen in the near future: Arctic warming by only a few degrees Celsius may trigger massive permafrost thawing, coastal erosion, and the release of greenhouse gases.

Membranes for capturing carbon dioxide from the air

(Kyushu University, I2CNER) CO¬2 capture from the air can mitigate further CO2 emissions, related increase in global temperature and climate change. Direct air capture of CO2 (DAC) is one of the promising ways for atmospheric CO2 extraction. In a new research paper, researchers propose CO2 capture from the air by membranes, which has been considered almost impossible for this challenging task.

A controllable membrane to pull carbon dioxide out of exhaust streams

(Massachusetts Institute of Technology) A system developed by chemical engineers at MIT could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.

RUDN University soil scientist: Paddy soil fertilization can help reduce greenhouse effect

(RUDN University) A soil scientist from RUDN University discovered the effect of fertilization on the ability of the soil to retain carbon. To understand this mechanism, he and his team studied the movement of organic carbon in the soil of rice paddies. The results of the study can help increase the fertility of the paddies while at the same time reducing the volume of greenhouse gases in the atmosphere.

Unprecedented energy use since 1950 has transformed humanity’s geologic footprint

(University of Colorado at Boulder) A new study makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch, known as the Anthropocene.
