One of the aims of the Paris Agreement was to "pursue efforts" to keep global warming below 1.5°C, but even this ambitious target would not stop the land's ability to absorb carbon weakening as wildfires become fiercer and more frequent, according to U.K. and Brazilian scientists. The climate simulations used to determine the 1.5°C Paris target lacked information about fire and vegetation, they say, so they ran simulations that included that data.
