Interesting show I saw on climate change. Graphs of CO2 levels for the past 60 years measured at Marina Loa correlate with trapped CO2 levels released and measured from ice cores taken at Antarctica. They have extended that graph measuring changes for the past 800,000 years, depicting rises and falls in CO2 levels. However, nothing in the record matches the high levels of CO2 we have now. The temperature record derived from ocean floor samples that look at shells’ growth also closely correlated with the CO2 graphs. This consistent match through thousands of years gives a picture that yes, increases in CO2 cause increased temps. However, we haven’t experienced quite the repercussions you’d expect from our production. Why? The trees are a huge repository for excess CO2, absorbing great quantities. The ocean is absorbing the heat. 3000 Dara diving robotis have been deployed that descend to 3k then 6k and slowly resurface gathering a myriad of data. In the South Seas ocean water appears to surface having been in currents on the ocean floor since the Industrial Revolution. This super cool water is our heat sink. It has already absorbed the 18 1/2 degrees the Earth should have warmed by now. How much long can we stress our planet without some change? The weather will give that report.
They estimate the Earth is giving us 50% reduction. We have to figure out how to meet Mother Earth half way.
