Not a record year, yet.
Figure 1: Acres burned (blue) and acres burned year-to-date 6 August (red), and log linear regression fit (black). Data before 1983 is collected using a different methodology, and hence is not strictly comparable to 1983-2018 data. Source: NIFC1, NIFC2.
The regression equation used to estimate the trend is:
log(ACRES) = 10.91 + 0.0433×TIME
bold denotes significance at 1% msl using HAC robust standard errors. Adj.-R2 = 0.46. DW = 2.09.
The coefficient on time can be interpreted as indicating that the number of acres burned is trending up at 4.3% per year, although a 95% confidence interval would encompass a figure as low as 2.9% and as high as 5.7%.
The correlation between suppression costs and acres burned is high (see this post). 2017 suppression costs by the Federal government (i.e., not including state costs) was $2.9 billion.
