Carbon dioxide is a greenhouse gas Due to human activities such as the combustion of fossil fuels and deforestation, and the increased release of CO2 from the oceans due to the increase in the Earth's temperature, the concentration of atmospheric carbon dioxide has increased by about 35% since the beginning of the age of industrialization. There is about 50 times as much carbon dissolved in the oceans in the form of CO2 and CO2 hydration products as exists in the atmosphere. The oceans act as an enormous carbon sink, having "absorbed about one-third of all human-generated CO2 emissions to date." Generally, gas solubility decreases as water temperature increases. Accordingly carbon dioxide is released from ocean water into the atmosphere as ocean temperatures rise. Most of the CO2 taken up by the ocean forms carbonic acid. Some is consumed in photosynthesis by organisms in the water, and a small proportion of that sinks and leaves the carbon cycle. There is considerable concern that as a result of increased CO2 in the atmosphere the acidity of seawater will increase and may adversely affect organisms living in the water. In particular, with increasing acidity, the availability of carbonates for forming shells decreases.

Carbon dioxide contributes to global warming by trapping heat in the atmosphere, leading to climate change. This has various negative effects like sea level rise, more frequent and severe weather events, disruptions to ecosystems, and impacts on agriculture and food security. Additionally, the ocean absorbs some of this excess CO2, which leads to ocean acidification, harming marine life and ecosystems.

The removal of carbon dioxide from the atmosphere can have a positive impact on global warming, in that the Earth is able to cool to a temperature which will no longer cause glaciers to melt. But if too much carbon dioxide is removed from the atmosphere, the Earth could become to cool and we could go into another ice age.

No, the opposite is true. Increase of carbon dioxide in the atmosphere means an increase in global warming.
