Global net anthropogenic greenhouse gas (GHG) emissions during the last decade (2010–2019) were higher than at any previous time in human history (high confidence).Since 2010, GHG emissions have continued to grow, reaching 59 ± 6.6 GtCO 2-eq in 2019, 1 but the average annual growth in the last decade (1.3%, 2010–2019) was lower than in the previous decade …

Warming cannot be limited to well below 2°C without rapid and deep reductions in energy system carbon dioxide (CO 2) and greenhouse gas (GHG) emissions. In scenarios limiting warming to 1.5°C (>50%) with no or limited overshoot (2°C (>67%) with action starting in 2020), net energy system CO 2 emissions (interquartile range) fall by 87–97% (60–79%) in 2050.

The IPCC released its most recent report focused on mitigation, or what can be done to prevent the worst effects of climate change. It was a mammoth undertaking with 278 authors from 16 countries reviewing more than 18,000 scientific papers and considered almost 60,000 comments from experts and governments as part of the drafting process.

This chapter builds on findings from the IPCC Fifth Assessment Report (AR5), the Special Report on Global Warming of 1.5°C (SR1.5), the Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) and the Special Report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse ...
