Study Notes

Global Warming Empirical Paper

Global temperatures are increasing non-stop, reaching record highs
A more sustainable future is needed to address this issue
Human activities, like burning fossil fuels, have emitted excessive CO2, impacting the atmosphere
Wildfires and volcanic eruptions also release CO2
CO2 emissions have increased from 11 billion tons in the 1960s to 36.6 billion tons in recent years
"Sinks" (natural processes) absorb about half of emitted CO2 annually, but excess emissions overload these processes.
The study aims to understand the relationship between CO2 emissions and global warming using temperature and CO2 data from 1959 to 2017.

Data Analysis Methods

The study analyzed temperature anomalies over different seasons (DJF, MAM, JJA, SON) from 1959 to 2017.
CO2 data were also analyzed
Statistical methods like calculating means, standard deviations, minimums, and maximums for different periods (DJF, MAM, JJA, SON) of the temperature and CO2 data sets were utilized
Scatter plots have been created for visual representation
