CO2 Levels continuously on the rise from 1980
Distribution of CO2 levels globally are on the rise
Distribution of Mean
Graph values:
• the quartiles: values corresponding to the 25th, 50th, 75th of all values
• interquartile range: the difference between the 75th and 25th value
• Range: the difference between the highest and lowest value

Temperature Anomalies and Number of Climate Related Disasters are on the rise
Shows that since 1980 both temperature anomalies and number of climate related disasters have increased significantly,
implying they could be related

The number of climate related disasters is related to the changes in temperature
There is a positive correlation between temperature anomalies and the number of climate related disasters from 1980 to 2022
Positive Correlation
When two variables move in the same direction: As temperature anomalies have increased so have the number
of climate related disasters
Temperature Anomalies:
Anomaly temperature=Absolute temperature-normal temperature

Temperature Anomalies in Celcius
*Finding absolute regional means have huge difficulties and create large uncertainties. This is why GISS prefers to use anomalies over absolute
temperatures.
*PMCC value is 0.79821298, indicating there is quite a strong positive correlation between the two variables
