This imbalance between greenhouse gas emissions and the ability for natural processes to absorb those emissions has resulted in a continued increase in atmospheric concentrations of greenhouse gases Concentrations of CO2 in the atmosphere have increased by about 40% since the mid1800sCLIMATE CHANGE IMPACTS OPPORTUNITIES If we double the amount of greenhouse gases in the atmosphere we expect to get a change in climate Ocean acidification, as co2 rises in the atmosphere the ocean absorbs it With a rise in co2 the ocean becomes more acidic as it dissolved in the salt water and forms carbonic acid this is corrosive to the shells and skeletons of manyWhen it is less than zero, it has a cooling effect
NOAA's Annual Greenhouse Gas Index, which tracks the warming influence of longlived greenhouse gases, has increased by 41 percent from 1990 to 17, up 1 percent from 16 with most of that attributable to rising carbon dioxide levels, according to NOAA climate scientists The greenhouse gas index is based on precise measurements of gases in the atmosphere,Climate change impacts can be mitigated by reducing greenhouse gas emissions and by enhancing sinks that absorb greenhouse gases from the atmosphere In order to limit global warming to less than 15 °C with a high likelihood of success, global greenhouse gas emissions needs to be netzero by 50, or by 70 with a 2 °C target Methane, by contrast, is mostly removed from the atmosphere by chemical reaction, persisting for about 12 years Thus although methane is a potent greenhouse gas, its effect is relatively shortlived
The amount of greenhouse gases in the atmosphere in the future will depend on the choices people make For example, if we continue to depend on coal, oil, and natural gas for most of our energy, the amount of greenhouse gases in the atmosphere will continue to increaseThe ratio of water component of the greenhouse effect to the CO 2 component is about 159 to 1 This means that the water vapor content of the atmosphere has to only fall from 041 percent to 0407 to wipe out the greenhouse effect of all the CO 2 in the atmosphere Given this sensitivity to the water vapor content it is clear that we really do not know whether the greenhouse gas To reduce the amount of CO2 in the atmosphere and fight deforestation, it may be a good idea to plant trees or take part in tree planting campaigns Separate collection is a simple and effective way to face greenhouse gas emissions and to pollute less Reduce meat consumption and prefer a diet rich in vegetables
