Oceans Turning Acidic Faster than Past 300 Million

Quote:

The oceans are becoming more acidic faster than they have in the past 300 million years, a period that includes four mass extinctions, researchers have found.

Quote:

Then, as is happening now, increases in carbon dioxide in the atmosphere warmed the planet and made the oceans more acidic. These changes are associated with major shifts in climate and mass extinctions.

Quote:

But while past increases in the atmosphere's carbon dioxide levels resulted from volcanoes and other natural causes, today that spike is due to human activities, the scientists note.

Quote:

"The current rate of (mainly fossil fuel) carbon dioxide release stands out as capable of driving a combination and magnitude of ocean geochemical changes potentially unparalleled in at least the last 300 million years of Earth history, raising the possibility that we are entering an unknown territory of marine ecosystem change," the researchers conclude in their paper.

Ocean acidification could turn out to be one of the biggest "bad" things to happen with global warming, if it starts knocking out the food chain earlier than expected.

The deniers always avoid talking about acidification because scientific measurements are showing that increased co2 levels are impacting marine life right now, and its harder to dispute because they cant just say "no".

His Dad was one of those dismissive types!

You know, the BIG SWINGING DICK types that he looked up to and wanted to emulate the nastiness of as he had no choice but to pay respect or endure what was behind the threat!

He never took the chance because his Dad was one of those bully boys, obviously!! Grin
