As they assemble to finalize a critical report, UN scientists are likely to include technology for removing CO2 from the atmosphere.
The Intergovernmental Panel on Climate Change will explore this suggestion as one of many options over the next two weeks (IPCC).
Government officials from around the world will also be in attendance, and each line of the summary report will need to be approved.
It will be released on April 4th.
This new study will be the third of the IPCC's three major reports released in the last eight months. The last two focused on the causes and effects of climate change, whereas this one will concentrate on mitigation, or what we can do to mitigate it.
This simply means that scientists will look for ways to limit the amount of warming gases released by human activity.
This mitigation report, according to the IPCC co-chair, will focus on strategies to remove CO2 that is already in the atmosphere.
"We have a lot more information on carbon dioxide removal this time. That is, rather of putting carbon into the atmosphere, it must be removed "Prof. Jim Skea of Imperial College, London, stated the following.
"The scope of the report was set to cover the entire range of carbon dioxide removal methods, which vary enormously, and the carbon dioxide that is removed can end up in a variety of stores and locations. So, basically, it was within the scope of the report to cover everything."
Tree planting and agriculture, as well as more advanced technology options that use massive machines to extract carbon from the air, are likely to be included in the report's considerations.
They'll also consider integrated techniques, such as using land to grow crops that can be used for energy while the carbon is trapped and buried.
The usage of this kind of technology is divisive. Campaigners are skeptical that they can be made to operate cheaply, and they are worried that technology will be used as an excuse to avoid making the necessary adjustments in energy generation.
However, scientists believe that the situation has become so dire that carbon dioxide removal will be required in addition to, rather than as a substitute for, huge reductions in emissions.
The outcome of the complex negotiations with government representatives from 195 countries, which will be released in two weeks, will determine what appears in the brief summary for policymakers.
To agree on the final language, researchers and officials will go over the summary line by line.
