Climate Change to Devastate Adélie Penguin Population in Antarctica by Up to 60%
At least 60 percent of Antarctica's Adélie penguin population could be wiped out by the end of this century due to climate change, new research shows. Colonies of Adélie penguins, which are only found in Antarctica, have been steadily declining since the 1980s parts of Antarctic that are warming, unable to raise chicks because of rising sea surface temperatures and reduced food supply.

Some parts of the continent are warming much more quickly than other and regions with more stable climates have seen steady penguins populations. Scientists predict that penguins will be forced to permanently migrate south to find more habitable conditions.

The climate crisis got its moment in the sun during the ninth Democratic primary debate in Las Vegas Wednesday.

One year after the Flint Water Crisis I was invited to participate in a water rights session at a conference hosted by the US Human Rights Network in Austin, Texas in 2015. The reason I was at the conference was to promote efforts by the American Association for the Advancement of Science (AAAS) to encourage scientists to shine a light on how science intersects with human rights, in the U.S. as well as in the context of international development. My plan was to sit at an information booth and share my stories about water quality projects I spearheaded in communities in Bangladesh, Colombia, and the Philippines. I did not expect to be thrown into conversations that made me reexamine how scientists use their knowledge as a public good.
The shipping industry is coming to grips with its egregious carbon footprint, as it has an outsized contribution to greenhouse gas emissions and to the dumping of chemicals into open seas. Already, the global shipping industry contributes about 2 percent of global carbon emissions, about the same as Germany, as the BBC reported.
The Jefferson Memorial in Washington, DC overlooks the Tidal Basin, a man-made body of water surrounded by cherry trees. Visitors can stroll along the water's edge, gazing up at the stately monument.
But at high tide, people are forced off parts of the path. Twice a day, the Tidal Basin floods and water spills onto the walkway.
