Excerpt: Mexico’s greenhouse gas emissions are the second highest among Latin American countries, trailing only Brazil according to the World Bank. But until now, no one had leveraged the full spectrum of available scientific data to make an estimate of sources (such as fossil fuel burning and agriculture) and sinks (such as healthy forests and soils) of carbon dioxide, methane, and nitrous oxide. Calculating the country’s greenhouse gas budget could help policymakers develop effective emissions reduction strategies. Murray-Tortarolo et al. calculate Mexico’s first comprehensive greenhouse gas budget based on estimates from multiple data sources of greenhouse gas fluxes in the country between 2000 and 2019. ...different sources of data broadly told the same story about anthropogenic greenhouse gas emissions from sources including fossil fuel burning and agriculture. However, there were discrepancies when it came to natural emissions sources such as wetlands and natural sinks such as forests and soils. In particular, the researchers found that studies may be overestimating the role that land ecosystems play in removing carbon from the atmosphere....
