How Much Do Humans Pollute? A Breakdown of Industrial, Vehicular and Household C02 Emissions

Each year, human beings release an increasing amount of carbon dioxide (C02) into the atmosphere; at present, around 40 billion tons per annum. According to NASA’s Earth Observatory, 8.4 billion tons are attributed to the burning of fossil fuels; primarily coal, gas and oil. The European Commission and Netherlands Environmental Assessment Agency lists the most polluting countries (including the EU as a whole and each of its member states). They are China, the US, the EU, India, Russia, Japan, Germany, Canada and Brazil. More

Climate change: There is more CO2 in the atmosphere today than any point since the evolution of humans – CNN

According to data from the Mauna Loa Observatory in Hawaii, the concentration of CO2 in the atmosphere is over 415 parts per million (ppm), far higher than at any point in the last 800,000 years, since before the evolution of homo sapiens.

Rainfall changes for key crops predicted even with reduced greenhouse gas emissions — ScienceDaily

By 2040, rainfall on wheat, soybean, rice and maize will have changed, even if Paris Agreement emissions targets are met; projections show parts of Europe, Africa, the Americas and Australia will be drier, while the tropics and north will be wetter.

Climate rewind: Scientists turn carbon dioxide back into coal: New technique can efficiently convert CO2 from gas into solid particles of carbon — ScienceDaily

Scientists have harnessed liquid metals to turn carbon dioxide back into solid coal, in research that offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere. The new technique can convert CO2 back into carbon at room temperature, a process that’s efficient and scalable. A side benefit is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles.

World’s biggest terrestrial carbon sinks are found in young forests — ScienceDaily

More than half of the carbon sink in the world’s forests is in areas where the trees are relatively young — under 140 years old — rather than in tropical rainforests, research shows.

Moving artificial leaves out of the lab and into the air

Researchers have proposed a design solution that could bring artificial leaves out of the lab and into the environment. Their improved leaf, which would use carbon dioxide — a potent greenhouse gas — from the air, would be at least 10 times more efficient than natural leaves at converting carbon dioxide to fuel.
