Groundbreaking Maps Detail Acidity of the Earth's Oceans
A team of scientists at Columbia University's Lamont-Doherty Earth Observatory and the University of Colorado at Boulder have published a groundbreaking set of maps that offer a comprehensive picture of the acidity of the Earth's oceans as they absorb climate change-causing carbon emissions, causing changes to marine ecosystems.
“We have established a global standard for future changes to be measured,” said Lamont-Doherty geophysicist Taro Takahashi, one of the team that developed the maps, which were published in Marine Chemistry. The maps take a month-by-month look at the increases and declines in ocean acidity in different seasons and locations, as well as saturation levels of calcium carbonate minerals used by shell-building organisms. They utilize four decades of measurements by Lamont-Doherty researchers and others.
Among other things, the maps show that the northern Indian Ocean is 10 percent more acidic than the Atlantic and Pacific Oceans, and that ocean water as far north as Iceland and as far south as Antarctica are acidifying by about 5 percent per decade, corresponding to the increase in carbon emissions.
While the chemistry will be over the heads of the average non-chemist, the maps are fascinating for how they make visual the impact we're having on our oceans and what that might mean for cultures and economies that depend on them.

On July 8, President Trump hosted a White House event to unabashedly tout his truly abysmal environmental record. The following day, coincidentally, marked the one-year anniversary of Andrew Wheeler at the helm of the U.S. Environmental Protection Agency (EPA), first as acting administrator and then as administrator after the Senate confirmed him in late February.

World hunger is on the rise for the third consecutive year after decades of decline, a new United Nations (UN) report says. The climate crisis ranks alongside conflict as the top cause of food shortages that force more than 821 million people worldwide to experience chronic hunger. That number includes more than 150 million children whose growth is stunted due to a lack of food.
