Climate change: WMO unveils plans for sustainable greenhouse gas monitoring

The WMO initiative would create a network of ground measurement stations who can verify disturbing air quality data that has been reported by satellites or planes, potentially within the next five years.

“At present, there is no comprehensive and timely international exchange of greenhouse gas observations from the surface and from space,” the UN agency said, as it urged for “enhanced (international) collaboration” and data exchange to support the 2015. Paris Agreementwhich provides a roadmap for carbon reduction and climate resilience.

Mystery of methane

“It’s not just anthropogenic emissions (that will be monitored), but what the forests do, what the oceans dosaid Dr Oksana Tarasova, Chief Scientist at WMO. “We need this information to support our mitigation measures, because we have no time to lose.”

In 2022, Dr. Tarasova continued, the WMO reported the largest ever observed increase in methane “and the reasons for this increase are still not known, so one of the functions of this proposed new infrastructure would be to help filling the gaps we have in our knowledge regarding the observations and regarding the use of these observations.

Climate of understanding

Cooperation between governments, international organizations and the private sector will be essential to make the proposed global greenhouse gas monitoring plan viable, the WMO said.

Equally important will be increased coordination between ground-based, airborne and space-based observation networks.

“With more precise and longer-term data, we will have a better understanding of our changing atmosphere,” the UN agency said. ” We will able to do more informed decisions and we will understand if the measures we have taken are having the desired effect.

Some governments and international organizations already carry out specific atmospheric monitoring and maintain data sets, but “there is no global steering mechanism and there is an undue reliance on research funding,” the WMO explained, in favor of the creation of a single, internationally coordinated atmospheric monitoring body. .

More electric vehicles on the road will mean less pollution and fewer greenhouse gas emissions.

Trace the race

The Earth’s atmosphere is mainly composed of nitrogen and oxygen, but there are also many different trace gases and particles that have a substantial impact on life and the natural environment.

Since industrialization, greenhouse gas emissions have dramatically changed the composition of the atmosphere.

In particular, the WMO has repeatedly warned that increasing levels of greenhouse gases such as carbon dioxide and methane are contributing to global warming and climate change.

These and other pollutants are also affecting air quality for humans, agriculture and ecosystemsthat’s why accurate measurements of the air we breathe are so important, say climatologists.

“Accurate and reliable data and knowledge on levels of pollution and atmospheric deposition also help us better understand their impacts on the environment, human health, loss of biodiversity, ecosystems and water quality, and to mitigate these impacts or put in place protective measures. “, said the UN agency.
