Ocean Acidification
milhayser | April 4, 2016In January, Hillary Clinton still possessed the benefit of the doubt. Memories of her and Bill snarling at Barack Obama in 2008 had faded, and despite her long and dreadful record, it's always possible to turn over a new leaf. But Clinton's ongoing response to Bernie Sanders shows why she is unfit for the presidency. Even as the frontrunner, Hillary shows no leadership ability; she, too, follows Sanders, trailing him to the left as he takes meaningful positions on issues like income inequality and campaign finance reform. Her saccharine smile says "I can do that too!" but truly she should be…
gregladen | September 1, 2015I've got a press release from the University of Southern California that seems important, but I don't have time today to read the study. So, you can look at the press release and tell me what you think of it.
Climate Change Will Irreversibly Force Key Ocean Bacteria into Overdrive
Scientists demonstrate that a key organism in the ocean’s foodweb will start reproducing at high speed as carbon dioxide levels rise, with no way to stop when nutrients become scarce
Imagine being in a car with the gas pedal stuck to the floor, heading toward a cliff’s edge. Metaphorically speaking, that’s what…
gregladen | February 11, 2013This graphic is from GRID-Arendal, a Norwegian Foundation collaborating with the UN Environment Programme. It shows CO2 concentrations in the ocean going up over a period of 20 eyars, and the corresponding drop in pH over the same time period.
Ocean acidification is a serious effect of climate change.
As carbon concentrations in the atmosphere increase, so do concentrations in the ocean, with resultant acidification as a natural chemical process.
There are more climate change related graphics HERE.
illconsidered | September 10, 2012Further to my mention of Ken Caldiera's recent Scientific American article "The Great Climate Experiment" the other day, I wanted to call attention to this passages as well:
the vast oceans resist change, but change they will. At no time in Earth’s past—with the possible exception of mass-extinction events—has ocean chemistry changed as much and as rapidly as scientists expect it to over the coming decades. When CO2 enters the oceans, it reacts with seawater to become carbonic acid. In high enough concentrations, this carbonic acid can cause the shells and skeletons of many marine organisms…
cwilcox | October 14, 2009**A post about Climate Change as a part of Blog Action Day 2009**When people talk about climate change, they, more often than not, talk about global warming. Yes, the effects of increased temperature will be diverse and generally bad for most creatures on Earth, including us. But the most dramatic effect of climate change won't be due to the heat - it will be due to ocean acidification. I might seem biased (being a marine biologist and all), but trust me, the addition of carbon dioxide to the ocean and its subsequent effects will be far worse in the long run than a change in temperature. Not…

Can you imagine oceans that have been emptied of all fish? What would life be like for other life forms on this planet if there really were no more fish in the sea? This is not science fiction: human-caused ocean acidification is already making its effects known. Sometimes known as the "wet underbelly" or "evil twin" of climate change, ocean acidification is caused by excess carbon dioxide from…

illconsidered | August 10, 2009I have mentioned it frequently before, there is another serious problem with pumping CO2 into the atmosphere, ocean acidification.
Geoengineering should never be discussed without mentioning it. The Way Things Break tells Nature as much.
cwilcox | July 16, 2009Following on the heels of Malaria, Bedbugs, Sea Lice and Sunsets and Southern Fried Science, I am posting this fantastic letter about ocean acidification by Randy Repass and Sally-Christine Rogers of West Marine (originally posted at The Intersection). Ocean acidification is, for me, the real crux of the issue when people talk about global warming or climate change. Acidification is a clear, very real chemical reaction between CO2 and seawater - there's no arguing its causes or consequences, which i suspect will be far more noticeable and painful in our lifetimes. Anyhow, read up!
We are both…
illconsidered | March 17, 2009While on the subject of interviews, I was recently contacted with an interview request by the website The Reef Tank. Loath to turn down any opportunity to talk about myself (what do you expect, I'm a blogger fer cryin' out loud!) I filled out the question sheet they sent over and you can read the interview here.
Given the marine life focus of their site, we discussed ocean acidification and the PETM event after a couple of blogging generalities.
They also asked my opinion of aquariums, with a warning it is controversial. I did not have much to say, and I guessed that the controversies must…
sheril | March 10, 2009The Guardian:
Human pollution is turning the seas into acid so quickly that the coming decades will recreate conditions not seen on Earth since the time of the dinosaurs, scientists will warn today.
Say what?! Look, ocean acidification is a VERY real threat to our planet. That said, the seas are not turning to acid! (But gee, way to scare folks into envisioning the demise of the wicked witch!) This demonstrates a lack of taking the time to explore and understand what ocean acidification means--the term is used to describe the way the pH of oceans is becoming less basic as they absorb…
illconsidered | October 29, 2007Real Climate has a good post on geo-engineering and why it is only fitting as a final act of desperation, not a policy platform. It expresses very well all my own misgivings (it's a terribly dangerous one-chance-to-get-it-right experiment on the entire planet, it commits the human race to centuries of climatic meddling, it will ultimately be more expensive and harder to agree on than simply reducing CO2) so I won't enumerate them here, just go read it all there.
But I will emphasize one of the points Ray Pierrehumbert mentions that is too often overlooked.
As anyone who follows the science…
