Global emissions of carbon dioxide have not decreased enough to meet the critical goal of limiting Earth's warming to 1.5 degrees Celsius above preindustrial levels, according to a new report authored by an international team of more than 100 scientists. In fact, average global temperatures are on track to cross that line within a decade, should warming continue at the current pace.
The Global Carbon Budget report, published online Thursday in the journal Earth System Science Data , is an annual update that tracks global CO2 emissions. The projections for 2022 are grim, estimating atmospheric CO2 at 417.2 parts per million — 51% above preindustrial levels — and global emissions at 40.6 billion tons . All figures in the report are projections, as the data cannot account for the final months of 2022.

Of particular concern is the increased conversion of carbon-dense forests into rice paddy fields and soybean farms by people in poorer regions.
