If we've only been collecting data on acidification for 20 years as she states then how can there be a measurement to get the 26% increase for the entire time of the Industrial Age?
When did the ocean acidification in the past lead to mass extinction? Over how many years did this happen approximately as well? If current rate at 10x worse than ever and it's going to be about 100 years to start affecting shell fish then it must have taken millennium or millennia to for this past mass extinction.
Pink oceans in the Permian Extinction because of acidification killing phytoplankton. We have already lost 40%of phytoplankton overall mass since the 60s.
I see on the right of this RUclips column, "Why renewables can't save the planet" by Michael Shellenberger. He is correct, and he used to think they could.
I'm wondering what effects the suez canel and panama canel have on the oceans. Especially taking into account the number of ships and god knows what localised in certain spots.
These are some valid points, but she missed a point. It's not just CO2 that increases ocean acidity. Burning fossil fuels also leads to the formation of SO3 and NO2, which make H2SO4 and HNO3. However -- adding more H2CO3 to the ocean will increase acidity too.
It's a bit late, but it's probably a CTD (Conductivity, Temperatur, Depth) sensor. Usually a CTD rosette with bottles that also take water samples at various depths for salinity, chlorinity, etc. measurements.
You no doubt meant "alkaline". Strangely enough, an alkaloid is something much more complicated than an alkali. Wikipedia says that most have a "bitter" taste, the opposite of "acidic" Perhaps the etymology is "It tastes like an alkali, b ut I know it isn't one."
What about the loss of oxygen in the oceans? When oxygen levels fell during the Jurassic Period, the new levels lasted for one million years before recovery....anyone has a 'smart' answer re: that? Any smart aleck answers there?
Unfortunately, the emitters of fossil carbon dioxide know that only nuclear power can put them out of business, which is about half of what needs to happen. The other half is to capture and chemically sequester that CO₂. Dr. Alex Cannara, who also warns at somewhat greater length about oceanic acidification, hopes that with even more nuclear power, it could be captured and driven down into the basalts with which it would combine.

So, indeed, why should I care?
Awesome explanation. Just wondering how much the water from melt ice would be -sadly- compensating the acidification, as well as affecting to salts concentration...
What they fail to tell you is that the areas they are talking about shellfish dying are all in "dead zones", places where the o2 has been depleted by fertilizer leaked into the rivers upstream. They tell you the deaths are caused by co2 because there is a correlation between the deaths and rising co2, but they fail to tell you that marine biologist have already proven those deaths were caused by lack of o2. They talk about reefs but fail to tell you that those reefs have recovered. The fail to talk about the hydrocarbon pollution in the water. They fail to mention that in some areas the water got hit by a cold mass of water causing bleaching. When the water warmed back up, the reefs recovered.
If we are in a natural warming cycle for the planet, the oceans should be warming. The amount of CO2 the oceans can dissolve is based on temperature. At a higher water temperature, the ocean holds less CO2, so actually, the ocean should be becoming more basic.
We shoulda started fixing climate change in th '60s, when it became public knowledge. Us hippies didn't follow thru on protecting the environment. I wish we hadn't let it go....

"Conveying scientific evidence along with an open acknowledgment of uncertainties to help separate evidence from judgment should not harm the need to act to mitigate ocean acidification" is a quote from that last paper hahaha
The oceans produce 50-75% of atmospheric oxigen - ocean warming and acidification will reduce the amount of oxygen produced - perhaps enough to most life on earth.
the ocean has not got more acidic, it has got slightly less neutral. ie it is still neutral but 0.0001 less neutral on the acidic side. absolutely irelevent

Try sequestering of CO2 via mass de-desertification by new agriculture techniques. There is mention of huge herds of grazers that would be able to turn arid land back into lush savannahs. The herds should move constantly though. The climate would change as well: image the Sahara Desert, not as a hot sandbox but as a grassland.
This Ted Talk was very interesting and brought up many facts about the ocean acidification rates. the dangers of ocean acidification not only for marine life but for us too was very surprising and a great motivator To want to help the ecosystem.
this explosion would be in a more steady environment, we are not saying that life is not possible in more acidic oceans, but the currents species are adapted to current conditions, and so changing conditions at this rapid pace will lead to huge problems for our oceans
This is a load of bollocks.. We currently have one of the lowest levels of CO2 in the atmosphere at about 340-400ppm (granted it has increased in the last 50 years) but some millions of years ago, it was over 1500ppm and life thrived and oceans were just fine. As a scientist, she failed to look at the full historical and empirical data and focused on data for 50 years which is a blip when talking about the planet and oceans

I don't partake in shellfish if I can help it
But you participate in oxygen!
Why didn't she mention the poss effects on the ocean forests that are providing our, I dunno, OXYGEN?
the ocean provides about 2/3 of our oxygen! So, yeah, the ocean is important, too.

What's the name of the instrument she used to take in samples, temperature information etc?
It's a bit late, but it's probably a CTD (Conductivity, Temperatur, Depth) sensor. Usually a CTD rosette with bottles that also take water samples at various depths for salinity, chlorinity, etc. measurements.
This is great
Is it possible for the oceans to be simultaneously alkaloid and acidity?
Wendy Simer The ocean will never be 'acidic' per se, but lower in pH than it should be. The pH has already decreased by 30% since industrialisation
You no doubt meant "alkaline". Strangely enough, an alkaloid is something much more complicated than an alkali. Wikipedia says that most have a "bitter" taste, the opposite of "acidic"
Perhaps the etymology is "It tastes like an alkali, b
ut I know it isn't one."
20 years of ph data does not a global trend make. And I am a bit suspect of that rate of ph decline. I would love to see the paper it is based on.
What about the loss of oxygen in the oceans? When oxygen levels fell during the Jurassic Period, the new levels lasted for one million years before recovery....anyone has a 'smart' answer re: that? Any smart aleck answers there?

Crab and all other arthropod shells are made of chitin, not carbonate. Surprised and disappointed to hear her make this mistake.
Chitin is the main part of the exoskeleton but some species harden their shell with carbonates as well like crustaceans.
Tinmothy maybe you should revise your sources, crab shells do contain carbonate ion so the argument of this talk remains valid
how do they know the oceans data from 100 years back when they didn't have that thing to measure
