Knowing how much carbon dioxide the ocean is storing is crucial to modeling future climate changes, and given the prevalence of these creatures around the world and how much water they can filter, it is likely a significant amount.
When you buy carbon offsets, you pay to take planet-warming carbon dioxide out of the atmosphere in exchange for the greenhouse gases you put in. For example, you can put money toward replanting trees, which absorb carbon dioxide from the atmosphere.
When whales die, their bodies sink to the bottom of the ocean and over time become part of the marine sediment layer, where they can sequester the carbon dioxide they have accumulated during their life span, an average of 33 tons for a great whale species, keeping it out of the atmosphere for hundreds or thousands of years.
As we burn fossil fuels, we release carbon dioxide, much of which is absorbed by the oceans.
Natural gas emits only half the carbon dioxide of coal when burned, but if methane leaks when oil companies extract it from the ground in a sloppy manner – methane is far more potent a greenhouse gas than carbon dioxide – it can wipe out all the advantages of natural gas over coal.
Centuries-old habitats such as coral gardens are destroyed in an instant by bottom trawls, pulverized by weighted nets into barren plains. And global carbon dioxide emissions from human activity affect the ocean, changing the pH balance of the waters in a phenomenon known as ocean acidification.
The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning.
Ocean acidification – the excess carbon dioxide in the atmosphere that is turning the oceans increasingly acid – is a slow but accelerating impact with consequences that will greatly overshadow all the oil spills put together. The warming trend that is CO2-related will overshadow all the oil spills that have ever occurred put together.
Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.
Plate tectonics is not all havoc and destruction. The slow movement of continents and ocean floors recycles carbon dioxide dissolved in the oceans back into the atmosphere. Without this slow speed carbon cycle, Earth’s temperatures would cool dozens of degrees below your comfort zone.
I support strongly the expansion of nuclear power because that is one of the key ways of getting electricity generated and reducing carbon dioxide emissions.
Carbon dioxide is unusual because it doesn’t go through the usual three phases of matter, from solid to liquid to gas, but it goes straight from solid to gas. The volume of the gas is much greater than the volume of the solid. When a solid turns into a gas, we say it sublimes. The process is sublimation.

We have to slow down the emissions of carbon dioxide and methane from coal burning, oil and eventually natural gas… And the best ways to do that are energy efficiency and a switch to renewables.
We need to be realistic. There is very little we can do now to stop the ice from disappearing from the North Pole in the summer. And we probably cannot prevent the melting of the permafrost and the resulting release of methane. In addition, I fear that we may be too late to help the oceans maintain their ability to absorb carbon dioxide.
If India moves towards 100 percent LED lighting, we will reduce almost 79 million tons of carbon dioxide from the atmosphere. This will also reduce the electricity bills of people.
The general trend in the last 4,000 years is that carbon dioxide and temperature have been moving against each other.
It’s not the case that carbon dioxide drives temperatures. When you leave Ice Ages, it’s the other way around: The temperatures go up first, and then carbon dioxide levels go up.
Ocean acidification is caused by the ocean absorbing excess carbon dioxide from the atmosphere, the same carbon dioxide that is the primary cause of global warming, hence the nickname ‘the other carbon problem.’ As they do so, the oceans become more acidic with terrible consequences.
I remember, as a boy of 17 years of age, this was a fascinating thing for me: how we human beings breathe out carbon dioxide into the air, the leaves of plants pick this carbon dioxide up, and the plant gives off oxygen, which we can breathe in and keep our life going.
We can look back through ice-core data and see over 800,000 years, relationships between carbon dioxide and the temperature of the world. So those people who deny the importance of climate change are just wasting their time. They’re also being diversionary because if we don’t act the risks are enormous.
Climate change is not just about carbon dioxide levels and melting polar ice caps. It is about our public health and protecting our Earth for future generations.
