All of this extra carbon needs to go somewhere.

So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has stayed in the atmosphere. Eventually, the land Effecy oceans will take up most of the extra carbon dioxide, but as much as 20 percent may remain in the atmosphere for many thousands of years. The changes in the carbon cycle impact each reservoir. Excess carbon in the atmosphere warms the planet and helps plants on land grow more.

Excess carbon The Greenhouse Effect Causes Impacts the ocean makes the water The Greenhouse Effect Causes Impacts acidic, putting marine life in danger. Carbon dioxide, methane, and halocarbons are greenhouse gases that absorb a wide range of energy—including infrared energy heat emitted by the Earth—and then re-emit it. The re-emitted energy travels out in all directions, but some returns to Earth, where it heats the surface. Without greenhouse gases, Earth would be a frozen degrees Celsius 0 degrees Fahrenheit.

With too many greenhouse gases, Earth would be like Venus, where the greenhouse atmosphere keeps temperatures around degrees Celsius Fahrenheit. Rising concentrations of carbon dioxide are warming the atmosphere. The increased temperature results in higher evaporation rates and a wetter atmosphere, which leads to a vicious cycle of further warming. Because scientists know which wavelengths of energy each greenhouse gas absorbs, and the concentration of the gases in the atmosphere, they can calculate how much each gas contributes to warming the planet. The rest is caused by small particles aerosols and minor greenhouse gases like methane. Warmer temperatures evaporate more water from the oceans, expand air masses, and lead to higher humidity. Cooling causes water vapor to condense and fall out as rain, sleet, or snow.

Carbon dioxide, on the other hand, remains a gas at a wider range of atmospheric temperatures than water.

Carbon dioxide molecules provide the initial greenhouse heating needed to maintain water vapor concentrations. When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapor drops. Likewise, when carbon dioxide concentrations rise, air temperatures go up, and more water vapor evaporates into the atmosphere—which then amplifies greenhouse heating.

So while carbon dioxide contributes less to the overall greenhouse effect than water vapor, scientists have found that carbon dioxide is the gas that sets the temperature. Carbon dioxide controls the amount of water vapor The Greenhouse Effect Causes Impacts the atmosphere and thus the size of the greenhouse effect.

Rising carbon dioxide concentrations are already causing the planet to heat up. At the same time that greenhouse gases have been increasing, average global temperatures have risen 0. With the seasonal cycle Grenhouse, the atmospheric carbon dioxide concentration measured at Mauna Loa Volcano, Hawaii, shows The Greenhouse Effect Causes Impacts steady increase since At the same time global average temperatures are rising as a go here of heat trapped by the additional CO 2 and increased water vapor concentration. The degree to which temperatures go up beyond that depends in part on how much more carbon humans release into the atmosphere in the future. About 30 percent of the carbon dioxide that people have put into the atmosphere has diffused into the ocean through the direct chemical exchange. Dissolving carbon dioxide in the ocean creates carbonic acid, which increases the acidity of the water.

Effects of Changing the Carbon Cycle

Or rather, a slightly alkaline ocean becomes a little less alkaline. Some of the excess CO 2 emitted by human activity dissolves in the ocean, becoming carbonic acid.

Increases in carbon dioxide are not only leading to warmer oceans, but also to more acidic oceans. Ocean acidification affects marine organisms in two ways.]
