Scientists working at American space agency, NASA have been keeping an eye on movement of CO2 on Earth.
NASA has been tracking the movement of Carbon dioxide or CO2across land, air and sea in order to determine the changes that are coming in the future. Experts said that the concentrations of CO2 are the highest in the atmosphere than ever in 400,000 years on the planet. Environmentalists pointed out that there are little hope that the carbon pollution from human activity will start falling and it is unlikely to reach zero any time soon.
They warned that the world is set to cross the symbolic atmospheric CO2 threshold of 400 parts per million (ppm) permanently this year or early next year. They said that this means that climate change will lead to warner temperatures and have other impacts like more acidic oceans, and shifts in extreme weather. NASA is this monitoring world’s greenery as without the plants, the impact would be worse. Factors including El Niño, drought and warm weather in the Arctic impact how much CO2 is taken up by the natural world and scientists are aiming to understand these factors.
Mike Freilich, the head of NASA’s Earth Science Division, said, “Some years, almost all of it stays in atmosphere and some years almost none of it remains in the atmosphere. So in those years it must all be absorbed into ocean and land.”
