In September 2017, a large iceberg roughly four times the size of Manhattan calved off of the Pine Island glacier in Antarctica (not to be confused with last July’s massive iceberg that originated from the Larcen C ice shelf further east). While the event itself isn’t that unusual — the Pine Island Glacier accounts for 25 percent of all of Antarctica’s annual ice loss — this iceberg began to break up shortly after separating from its host glacier, instead of doing so after drifting far out into the Southern Ocean, as ‘bergs from Pine Island typically do.read more

An increase in the number of devastating earthquakes around the world is being predicted for 2018, according to the University of Colorado’s Roger Bilham and Rebecca Bendick of the University of Montana. The two geologists have made a detailed study on earthquake activity recorded since 1900, and found that increases in the number of major earthquakes tend to follow predictable cycles, and 2018 happens to fall in one of those years.

The infamous hole in Earth’s ozone layer has shrunk down to 7.6 million square miles wide (12,200,000 square kilometers), the smallest the gap has been since 1988. This healing of Earth’s main shield against ultraviolet radiation is due largely to efforts initiated in the mid-1980s, when the use of ozone-harming CFCs was phased out. Not only is this positive news in regards to our atmosphere’s ability to filter out harmful UV radiation, it also stands as an example of how humanity can make a positive, large-scale impact when efforts to reduce ecological harm are required, such as in the case of our need to reduce greenhouse gas emissions.

Environmental Protection Agency Administrator Scott Pruitt has signed a new directive that prevents scientists that are receiving grants from the EPA from serving on the agency’s advisory committees. Pruitt says that this unprecedented move is to remove what he perceives to be a potential bias from the committees, stating that the members of three key EPA boards — the Science Advisory Board, Clean Air Scientific Advisory Committee, and Board of Scientific Counselors — have received an estimated $77 million in agency funding. The move was quickly criticized by scientists and environmentalists as one that would bar the country’s most qualified scientists from these committees, and at the same time leave the door open for Pruitt to appoint industry-friendly members to advise the EPA.read more
