Carbon dioxide emissions continue to increase and has not stabilized

A recent New York Times article (Link) posits that carbon dioxide concentration in the atmosphere continues to increase, due to the failure of Earth’s oceans and vegetations at absorbing carbon dioxide in a scenario that carbon dioxide emissions have stabilized across the world. The pertinent time period is 2015 and 2016.   My personal opinion … More Carbon dioxide emissions continue to increase and has not stabilized

Understanding past climate from bubbles trapped in ice cores

We know the past from a historical record of it written on paper, inscribed in stone, or from depictions of events entrapped in fossils. To understand past climates, scientists look for bubbles of past atmospheres trapped in ice cores as historical record of what happened. Typically, these ice cores could be obtained from three types … More Understanding past climate from bubbles trapped in ice cores
