Microalgae contain chlorophyll and, similarly to plants, they assimilate atmospheric carbon dioxide(CO2) to produce oxygen(O2) through the process of photosynthesis.
The plant, built with an innovative hybrid system that also includes an energy storage system, will facilitate integration with existing turbines, reducing gas consumption, operating costs and atmospheric carbon dioxide emissions.
Each year since detailed recordkeeping began in 1959, the concentration of CO2 in the atmosphere has climbed to a new high, making it one of the most predictable of all global environmental trends.
The level of carbon dioxide in the atmosphere has surpassed 400 parts per million for the first time in human history, US monitors say, sparking new calls for action to scale back greenhouse gases.
As a result of this, more of the CO2 bound in organic matter remains in the surface layer, which reduces the ocean's potential to take up atmospheric CO2.".
With emissions set to zero in the simulations, the level of carbon dioxide in the atmosphere slowly fell as carbon“sinks” such as the oceans and land vegetation absorbed the gas.
Reconstruction of giant panda habitat fragmentation Forest carbon sink through forest absorption of carbon dioxide in the atmosphere and fixed in vegetation or soil, thereby reducing the concentration of carbon dioxide in the atmosphere.
The most recent science tells us that unless we can reduce the amount of carbon dioxide in the atmosphere to 350 parts per million, we will cause huge and irreversible damage to the earth.
A new NASA study provided space-based evidence that Earth's tropical regions were the cause of the largest annual increases in atmospheric carbon dioxide concentration seen in at least 2,000 years.
The dip in atmospheric carbon dioxide levels during the Little Ice Age wasn't caused by New World pioneers cutting a swathe through native American agriculture, as had been previously thought.
We could generate hydrogen by splitting water and combining it with carbon harvested from CO2 in the atmosphere, making fuels like methanol, ammonia, and dimethyl ether, which could be a direct replacement for diesel fuels.
The hope is that the level of CO2 in the atmosphere can thus be kept below what is widely agreed to be the upper limit for a tolerable level of global warming, 450 parts per million.
The density of carbon dioxide in the atmosphere, which was about 280 ppm around 1900, is now 363 ppm and the average temperature of the earth rose by 0.5 centigrade these 100 years.
