CO2 Emissions are going down!

2024-08-27 23:36:02 UTC

My 5th grade daughter and I learned about how CO2 emissions are ever so slowly beginning to decrease in some of the wealthier more populous countries (we'd have to normalize a bit for population but it made us happy to see the green US bubble go down over the last decade) - this was at the very end after we changed the y axis from life expectancy to CO2 emissions.

1917 - a difficult year

The life expectancy dropped for LOTS of countries due in part to the Spanish Flu.

People in Small, Wealthy Nations Live Long Lives

My daughter and I also learned that Singapore and Luxembourg are among the wealthiest nations with high life expectancy (although they are really really small!)

Life expectancy for the most part was consistent during 1800s and GDP regressed then during 1893 there was a drop in life expectancy. In 1918 there was another deep drop in life expectancy then the bubble just goes all over the place....no specific trend. Wondering what might have caused these drops?

We also noticed during war times, bubbles dropped

I discovered that the life expectancy in India plummeted in 1918 due to the flu pandemic. I did a search on wikipedia and found out that the outbreak most severely affected 20-40 year olds. The year 1919 saw a reduction in births by around 30 percent.

Small country, big swings in life expectations

I looked at Finland because it was such a small dot that started at/near top in life expectancy. As I followed the bubble I was amazed at the huge swings in life expectancy over time. Might this be because the population is so small so differences have a larger effect? So I looked at 2 of the big dots--China and India--and didn't see such a wide range of life expectancy changes over time.
