Carbon emissions from human activity does not just go straight into the atmosphere, causing the planet to heat up. While a large percentage of it doesroughly halfsome of it is absorbed into the ocean. And now new research has found there has been some miscalculations on how much carbon dioxide is being absorbed by the ocean.

The new study found that previous climate models only took into consideration the surface temperature of the ocean when calculating how much is absorbed by Earth’s water.

The cooler the ocean, the more CO2 it absorbs. However, just a few metres beneath the surface, the temperature of the ocean begins to drop drastically.

Professor Andrew Watson, of the University of Exeter’s Global Systems Institute, said: “Half of the carbon dioxide we emit doesn’t stay in the atmosphere but is taken up by the oceans and land vegetation ‘sinks’.

“Researchers have assembled a large database of near-surface carbon dioxide measurements — the ‘Surface Ocean Carbon Atlas— that can be used to calculate the flux of CO2 from the atmosphere into the ocean.

“Previous studies that have done this have, however, ignored small temperature differences between the surface of the ocean and the depth of a few meters where the measurements are made.

“We used satellite data to correct for these temperature differences, and when we do that it makes a big difference — we get a substantially larger flux going into the ocean.

“The difference in ocean uptake we calculate amounts to about 10 percent of global fossil fuel emissions.”

Dr Jamie Shutler, of the Centre for Geography and Environmental Science on Exeter’s Penryn Campus in Cornwall, added: “Our revised estimate agrees much better than previously with an independent method of calculating how much carbon dioxide is being taken up by the ocean.

“That method makes use of a global ocean survey by research ships over decades, to calculate how the inventory of carbon in the ocean has increased.

“These two ‘big data’ estimates of the ocean sink for CO2 now agree pretty well, which gives us added confidence in them.”

However, it is not good news for Earth that not as much CO2 is being ploughed into the atmosphere.

This can drastically change the delicate ecosystems as it can destroy coral reefs and damage marine life.
