The findings, which were published in the journal […]
by Dave Clark and Stephanie Aglietti KIGALI, Rwanda | AFP | — In a major step toward curbing global warming, the world community agreed on Saturday to phase out a category of dangerous greenhouse gases widely used in refrigerators and air conditioners.

WASHINGTON, United States (AFP) — Scientists have turned carbon dioxide into stone in a matter of months by pumping it deep underground, offering a revolutionary new way of storing the greenhouse gas to tackle climate change. The pioneering experiment in Iceland mixed CO2 emissions with water and pumped it hundreds of meters (feet) underground into volcanic basalt rock — where it rapidly turned into a solid. “We need to deal with rising carbon emissions. This […]
