Climate change: what is ocean acidification?

As carbon emissions change the chemistry of the seas, ocean acidification threatens marine life and human livelihoods. How worried should you be about climate change’s so-called “evil twin”?

We need more of these videos. Insight into a world a lot of us don't know.

Climate change is very informative. The world is unaware that the acids and carbon in the ocean destroy aquatic life, which has an impact on the food chain. We need to hear more stories like this. Bravo for this video's superb reporting.

Instead of wasting money on war and nuclear weapons, Developed countries should invest more money on protect nature and reduce the threat of global warming.

It's sad that nothing will be done until it starts to heavily affect people who live inland. I genuinely don't think humans will ever care tho.. 😔

[MujahidAli-csfk]

The awareness created in these are amazing things we can do.

[jane-BKK]

more stories like this please.... the world lacks knowledge that the acids and carbon in the ocean kills living being inside the water, which will then have repercussion to food chain... well done for this clip... excellent reporting.

Very informative and revealing. The Economist never fails to deliver well supported research with verifiable information.

Main causes of C02 emissions:

Burning fossil fuels:
The largest source of CO2 emissions is the burning of fossil fuels such as coal, oil, and natural gas for energy. This includes emissions from electricity generation, transportation, and industrial processes.

Land-use changes:
Deforestation and land-use changes, such as conversion of forests to agricultural land, can release large amounts of carbon dioxide into the atmosphere.

Agriculture:
Agriculture, particularly livestock farming, is a significant source of greenhouse gas emissions, primarily methane and nitrous oxide.

Industrial processes:
The production of cement, steel, and other industrial products can release large amounts of CO2 emissions.

Residential and commercial buildings:
Energy use in buildings for heating, cooling, and electricity can also contribute to CO2 emissions.

We know the cause, we have some solutions. The only things that are preventing us from making changes are the people, governments and companies that are currently profiting from our current way of life, its not sustainable. Words are getting us nowhere... Actions speak louder than words.

Heimdall is not commercially viable
but the seagrass, yeah that makes perfect sense

Wittgenstein O - “Reminder - At Davos they ate the most expensive beef from Japan and the best foods not a insect in sight. Insisted on planes being piloted by unjabbed pilots. Flew in on private jets and helicoptered to waiting SUVs. Hypocrisy at its
finest.”

[HusnaFazalAhmed]

Countries should meet to discuss on climate if they are committed to take action and take responsibility based on their economic and capacity

[andrewgonzales]

The Economist does not have the interests of the environment in mind.

[AmandaHugandKiss]

What can be done? Nothing, deal with the fact that the Earth has always been changing and will continue to.

[randomguy]

I don't understand some of the comments here, what do they have against combating climate change? and how is this topic even still debated, it is well established that we caused climate change and it should be stopped. Really bewilders me how there are still people not believing it exists.

[Bendovermf]

Wow! Amazing work keep it up! It’s totally amazing seeing these kind of animals!❤

That paper was written fifteen years ago.

How does melting ice caps affect the ocean acidification?

[drmosfet]

The only answer currently is nuclear fission, unfortunately the nuclear industry is highly reluctant to update there reactors to a safer non-uranium and water design like Thorium Molten Salt Reactor. So if you're planning on fish&chips in the distant future you will be paying dearly for it, from a aquaponics Farm that grows tilapia a reasonable cod substitute. The farm will most likely be powered by a thorium reactor purchased from China.

Why are some people stressing themselves about climate change, we live on an evolutionary planet. The animals we now know and all our ecosystems have all evolved after numerous heating and cooling episodes. Get on with living the best life you can while been kind and respectful to your fellow human beings. Our lives only amount to a split second on the evolutionary time clock.

Fun fact, we need to reverse CO2 emissions and not just reduce. Reduction is already an impossible task....we are doomed.
