Remove carbon dioxide from the air or risk young people’s future
18 July 2017
Greenhouse gases, including carbon dioxide, trap energy from the Sun in the Earth’s atmosphere. Human activities including farming, transport and industry release a large amount of these gases to the air. There is so much in the atmosphere now, that the Earth is heating up faster than at any time in the planet’s recent history. This global warming will have unpleasant consequences, such as more frequent and severe heat waves or droughts, as well as a rise in sea level, which could affect millions of people living in coastal areas.
We can limit these effects by reducing the amount of greenhouse gases we release to the atmosphere: by using energy more efficiently and from renewable sources, improving air conditioners or eating less meat, for example. But a new study published in Earth System Dynamics says this will not be enough. According to a team of scientists led by James Hansen, a professor at the Columbia University Earth Institute in the US, formerly at NASA, we also need to remove some of the carbon dioxide already in the atmosphere to limit warming to a level that would safeguard children’s futures.
Hansen says that If we start to reduce how much we emit right now, we only need to remove a small amount of carbon dioxide from the atmosphere to ensure warming does not get out of hand. Simple and relatively cheap measures, such as planting more trees, could do the trick. But if we continue to release greenhouse gases the way we have been doing, we would need to develop new technology to suck up huge amounts of carbon dioxide from the atmosphere to avoid global warming’s most dangerous consequences.
“It is apparent that governments are leaving this problem on the shoulders of young people. This will not be easy or inexpensive,” says James. Hopefully this study will encourage governments to take action against global warming.
