Observed and Projected Temperature Change

Figure 18.1

This figure appears in chapter 18 of the NOAA-led State Summaries 2019 report.

Observed and projected changes (compared to the 1901–1960 average) in near-surface air temperature for Louisiana. Observed data are for 1900–2018. Projected changes for 2006– 2100 are from global climate models for two possible futures: one in which greenhouse gas emissions continue to increase (higher emissions) and another in which greenhouse gas emissions increase at a slower rate (lower emissions)1. Temperatures in Louisiana (orange line) have risen little since the beginning of the 20th century. Shading indicates the range of annual temperatures from the set of models. Observed temperatures are generally within the envelope of model simulations of the historical period (gray shading). Historically unprecedented warming is projected during the 21st century. Less warming is expected under a lower emissions future (the coldest years being about as warm as the hottest year in the historical record; green shading) and more warming under a higher emissions future (the hottest years being about 10°F warmer than the hottest year in the historical record; red shading).
