A Billion-Year History of CO2 in our Atmosphere | - …

12/08/2020· At the time, atmospheric CO2 concentration was at a whopping 3000 to 9000 ppm! The average temperature wasn’t much more than 10 degrees C above today’s, and those of you who have heard of the runaway hothouse Earth scenario may wonder why it didn’t happen then. Major factors were that the Sun was cooler, and the planet’s orbital cycles were different.

Life on Earth was nearly doomed by too little CO2 – Watts Up …

30/06/2017· In fact, Earth’s atmosphere had only about 180 parts per million CO2, compared to today’s 400 ppm: % then versus % today. The Ice Age’s combined horrors – intense cold, permanent drought and CO2 starvation – killed most of the plants on Earth. Only a few trees survived, in the mildest climates. Much of the planet’s grass turned to tundra, which is much less nourishing to the …
