Carbon dating proved false
Only 0.3 Gt C/y rains down in the form of carbonate oozes of marine sediments of which a massive 30 million Gt C exists, to be circulated to the surface through ocean floor spreading, subduction and volcanic activity, which takes 100 million years.
But the ocean is vast and CO2 has an uncanny affinity with water.
It is thought that this contribution is the cause of the observed increase in the concentration of CO2 in the atmosphere from a supposed 180ppm pre-industrial to a present-day 400ppm.
So there is good certainty that the amount of CO2 in the air is rising. Many scientists believe it is caused by the burning of fossil fuels and other human activities, but considering the presence of a huge reservoir of carbondioxide in the ocean, one should ask whether the tail is wagging the dog (see box below).
Begin your study of the environment at the Seafriends home page or our sitemap.The surface 100m with 600Gt C is perturbed a few times per year, contributing almost instantly to warming, or 18 Gt/ºC (carbon), or 10ppmv/ºC. Endersbee's figure of ~300 lies comfortably between .Reader, as you may notice, there is a lot of uncertainty here.When there is an archaeological find, earth has to be carefully removed to expose buried artefacts or building structures.Excluding nearby volcanic disasters, what causes a site to fill up with rubble and debris over time? • Your correspondent will find Charles Darwin’s book about earthworms, On the Formation of […] In the search for extraterrestrial life, we look for planets at a similar distance from their sun as Earth is from ours: the so-called Goldilocks zone.
Thus the oceans, while warming, do not absorb the extra CO2 from fossil fuel, but they do recycle it. Update Aug 2011: Endersbee's curve is heavily contested mainly because he took a period in which both temperature and CO2 were rising.
