Description

This data set is composed of annual world total CO2 emissions, wheat production, harvested area, wheat production per hectare, and annual average temperature anomalies series between 1960 and 2017.

Usage

data(wheat)

Format

Multiple time series

CO2..ppm. column shows the global mean annual concentration of carbon dioxide (CO2) measured in parts per million (ppm).

CO2..tons column shows the global mean annual carbon dioxide (CO2) emissions measured in tons.

HarvestedArea..million.ha. column shows the annual harvested area in the world scale in million hectare.

Production..Mt. column shows the annual world wheat production in million tons.

ProducationPerArea column shows the annual wheat production per hectare in tons.

TempAnomaly..C.degrees. column shows the land-ocean temperature index without smoothing.
