hockeystick includes functions to download and visualized climate data. Data is optionally cached.

Retrieve NOAA/ESRL Mauna Loa CO₂ Observatory concentration data and plot:

library(hockeystick)
ml_co2 <- get_carbon()
plot_carbon(ml_co2)

Retrieve GCP global CO₂ emissions and plot:

emissions <- get_emissions()
plot_emissions(emissions)

plot_emissions_with_land(emissions)

Retrieve 2081-2100 temperature projections and map:

proj <- get_cmip6()
plot_cmip6(proj)

Retrieve 2081-2100 precipation anomaly and map:

anom <- get_cmip6_anom(var = 'prec')
plot_cmip6_anom(anom)

Visualize cumulative emissions by country:

emissions_map()

Retrieve NASA/GISS global surface temperature anomaly data and plot:

anomaly <- get_temp()
plot_temp(anomaly)

Plot relationship between temperature anomaly and carbon:

plot_carbontemp()

Visualize warming using Ed Hawkins styled “warming stripes”:

warming_stripes()

warming_stripes(stripe_only = TRUE, col_strip = viridisLite::viridis(11))

Retrieve tide gauge and satellite sea level data and plot:

gmsl <- get_sealevel()
plot_sealevel(gmsl)

Retrieve July annual Arctic Sea Ice Index and plot:

seaice <- get_seaice()
plot_seaice(seaice)

get_seaice() arguments can be modified to download Antarctic sea ice, and allow any month.

You can also visualize sea ice by month and year:

arcticice <- get_icecurves()
plot_icecurves(arcticice)

Retrieve NOAA HURDAT2 hurricane data and plot:

hurricanes <- get_hurricanes()
plot_hurricanes(hurricanes)

plot_hurricane_nrg(hurricanes)

Retrieve GWIS wildfire data and plot:

usfires <- get_fires_area(place='USA', year = 2026)
plot_fires_area(usfires)

plot_fires_area(usfires, style = 'weekly')

Retrieve NOAA/ESRL CH₄ Globally averaged mean data and plot:

ch4 <- get_methane()
plot_methane(ch4)

Retrieve Vostok paleo ice core data and plot:

vostok <- get_paleo()
plot_paleo(vostok)

Managing the cache

By default, no climate data is cached, and all data is downloaded every time any of the get_ functions is called. To cache data for future use, use the write_cache = TRUE option, available in all of the get_ functions. To download and cache all data use hockeystick_update_all(). To view the files, date, and size of cached data use hockeystick_cache_details(). To re-download data from the source use the use_cache = FALSE argument in any of the get_ functions, for example: get_carbon(use_cache = FALSE, write_cache = TRUE). To delete all cached data use hockeystick_cache_delete_all().

Users may also cache data by default by adding options(hs_write_cache = TRUE)to their script or .Rprofile file.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
