Wildfire smoke is made up of a range of gases, including carbon monoxide; nitrogen dioxide; polycyclic aromatic hydrocarbons, or PAHs; and hazardous particulate matter, which has been shown to increase risks of respiratory and cardiovascular illnesses in humans.
“The overall big picture here is that surface water carbon dioxide levels are indeed increasing in the Gulf of Mexico (except in the central Gulf) and human activities are contributing to this acidification,” says Shamberger. “Also, coastal acidification is occurring faster than open ocean acidification, which is especially troubling for coastal coral reef and shellfish ecosystems that support many important fisheries species.”
The report makes clear that to protect the ocean, we must first reduce our dependence on fossil fuels. But we must also reduce ocean stress, caused by overfishing and pollution, so the ocean is healthy enough to weather the changes already underway.
“The bottom line is that we need the ocean. And right now, the ocean needs us,” said Julie Packard, executive director of the Aquarium. “It’s not too late to take courageous climate action and safeguard the ocean from further damage.”
As the amount of atmospheric carbon dioxide continues to rise, our oceans are playing an increasingly important role in absorbing some of this excess. In fact, it was reported recently that the global ocean annually draws down about a third… Read More ›
Research published this week in the peer-reviewed journal Science analyzed more than 100,000 seawater samples worldwide collected from 1994 to 2007 and taken from nearly every corner and depth of ocean.
The analysis found the oceans are absorbing about 31 percent of the carbon humans are spewing into the world. For context, the weight of the carbon seeping into the ocean each year, on average for the period of study, is roughly equivalent to 2.6 billion Volkswagen Beetle cars, Feely said.
