What is Charles Keeling known for?
Keeling Curve
Charles David Keeling/Known for
The journey all started for Gore as a college student, was challenged numerous times during his political career, and was highlighted by his blockbuster documentary An Inconvenient Truth. Roger Revelle, an oceanographer and the first scientist to measure CO2 levels in the atmosphere, mentored a young and spirited Gore.
What did Keeling discover?
Keeling, as a young researcher, became the first person in the world to develop an accurate technique for measuring carbon dioxide in the air, the amount he discovered was 310 parts per million. That means every million pints of air, for example, contained 310 pints of carbon dioxide.
What is the role of co2 in greenhouse effect?
The greenhouse effect works much the same way on Earth. Gases in the atmosphere, such as carbon dioxide, trap heat similar to the glass roof of a greenhouse. These heat-trapping gases are called greenhouse gases. At night, Earth’s surface cools, releasing heat back into the air.
What will CO2 levels be in 2050?
Based on a business-as-usual trend, global carbon dioxide emissions are forecast to increase to some 43.08 billion metric tons in 2050, in comparison to 35.3 billion metric tons of carbon dioxide in 2018. Carbon dioxide emissions reached its highest level in 2018 due to a strong economy and extreme weather conditions.
How much CO2 can the earth handle?
But too many different numbers are still floating around. We could have more than 500 billion tons of carbon that we could safely emit, or the real figure might be close to 100 billion tons — it depends on whose estimates you decide to accept.
What does the Keeling Curve tell us?
The Keeling Curve is a graph that shows the ongoing change in the concentration of carbon dioxide in the Earth’s atmosphere.
