For GSS A New World View chapter 5. Excerpt: The vast expanses of rainforest that make up the Amazon Basin have been called the lungs of the planet, as they breathe in carbon dioxide and release oxygen. Now, findings from biweekly airplane flights over the jungle show how a severe drought choked these lungs, constricting the uptake of carbon dioxide, a greenhouse gas. Worse, fires released tremendous amounts of carbon into the atmosphere, exacerbating global warming. ...Scientists are concerned that climate change—with rising temperatures and more droughts—will reduce the rainforest’s storage of carbon and in turn hinder its ability to slow the pace of global warming. http://news.sciencemag.org/climate/2014/02/scienceshot-fire-blackening-earths-lungs.
