Capitalism Notes (lectures 10-21)

CO2 Increase

CO2 levels have risen by 50% from 1815 to the present day due to human activities increasing greenhouse gases in the atmosphere.

Annual CO2 Emissions

Countries like China have the largest emissions due to coal usage, followed by oil, gas, and traditional biomass.

Temperature Measurement Challenges

Measuring global temperatures is complex due to factors like urban heat islands, but methods like fossils, tree rings, and ice cores help understand past temperatures.

Ice Ages Initiation

Temperature changes precede CO2 changes in initiating ice ages, indicating a natural occurrence before human-induced emissions.

Climate Change Impact

Volcanic eruptions can cool the Earth temporarily, while global warming poses risks like extreme weather events and the need for sustainable solutions.

Debt and Economy

National debt is used for emergencies and economic stability, impacting future generations, with the US facing challenges in balancing debt and GDP ratios.

Retirement Systems

Retirement plans like Social Security benefit low-income workers more, funded either in advance or through pay-as-you-go systems, affecting income distribution and economic growth.

Income Inequality Measurement

The Gini Coefficient and Lorenz curve help measure income distribution, with theories like Picketty's highlighting the impact of interest rates on wealth inequality.
