Earth’s average temperature has warmed by 0.8 degree Celsiusover the last 100 years or so. The reason is increasing concentrations of greenhouse gases, particularly carbon dioxide, in the atmosphere.
The concentration of CO2 has now reached 394 parts-per-million in the air we breathe—and would be even higher, roughly 450 ppm, if the oceans weren’t absorbing a good deal of the CO2 we create by burning fossil fuels, clearing forests and the like. Via Athena Drakou Delete the scoop?
