Study shows that nitrogen emissions could alleviate climate warming

The latest findings on the effects of nitrogen emissions from agriculture on the climate cause a sensation and simply throw a complex interactions between human activities and the global increase in temperature.

nitrogen emissions and their global effects

A study carried out under the direction of the Max Planck Institute for BioGeochemistry in Jena shows that the nitrogen emissions caused by humans have a surprising cooling effect on the global average temperature. The researchers analyzed, such as nitrogen compounds, which are released by the use of fertilizers and the combustion of fossil fuels.

cooling versus warming effects

The scientists find that nitrogen have both positive and negative effect on the climate. For example, laughing gas, which escapes from fertilized soils, ensures that the atmosphere is heated as a strong greenhouse gas. Nevertheless, nitrogen entries promote plant growth, which leads to an increased CO2 bond and thus has a cooling effect. If you combine all of these effects, it is estimated that the nitrogen emissions compensate for a sixth of the previous global warming by increasing the CO2.

The real danger: health and environment

Although the study emphasizes the cooling effect of nitrogen emissions, the researchers underline the considerable health and environmental consequences. According to Fortunat Joos, co -author of the study, over 2000 early deaths per year are due to air pollution caused by nitrogen emissions. The researchers warn of the risks of over -fertilization that can burden water and lead to the formation of fine dust.

urgency of action

The results of the study show that there is an urgent need for action. Joos calls for a targeted use of fertilizers and an end to emissions from fossil fuels. Such a step could not only slow climate warming, but also significantly reduce the health risks associated with ozone and fine dust.

conclusion: Balance find between agriculture and climate protection

Overall, the results show that nitrogen emissions represent a complex challenge. Agriculture could contribute to reducing these emissions through sustainable practices, which would benefit both the environment and human health. The leading scientists appeal to society more consciously with the use of fertilizers and to promote more environmentally friendly methods.
