Melting Antarctic ice may strangle vital ocean currents

As Antarctic ice melts, all of that fresh water pours into the ocean, essentially diluting it by reducing its salinity. That, in turn, is dramatically slowing the currents that, like a conveyor belt, carry oxygen, carbon dioxide, and nutrients through the sea and around the world. A study published last week in the journal Nature

Melting sea ice is acidifying the Arctic Ocean

Climate change is changing the chemistry of the Earth’s oceans. The heat from increased carbon dioxide in the atmosphere is melting critical sea ice and causing ocean acidification, or a reduction in the pH of the ocean over an extended period of time. Over the past 200 years, the pH of surface ocean waters has

Could Melting Arctic Sea Ice Play A Role In U.S. Wildfires?

Scientists for the first time have been able to describe the underlying mechanism behind the relationship between melting Arctic sea ice and worsening wildfires in the western United States. As sea ice melts from July to October, sunlight warms the increasingly iceless, surrounding area, according to a new study. This ultimately brings heat and fire-favorable…
