Are We Willing To Risk It ?

It transpires that Carbon Dioxide levels during some of the “hot house” periods of Earth history may have been relatively low.

Is it possible that hellish conditions could emerge from having a concentration of 1,000 ppm of Carbon Dioxide in the Atmosphere ?

Some projections have residual airborne levels of Fossil Fuel and deforestation emissions reaching that kind of count by the year 2100.

Are we willing to risk it ?

“Published online: 14 January 2010 : Insights from earth : Alicia Newton : Atmospheric carbon dioxide levels during some of the hottest periods of the Earth’s past may have been much lower than once thought. An analysis of soils shows that during eras of extreme warming 251 – 65 million years ago and 55 million years ago, carbon dioxide concentrations were similar to those anticipated for 2100 under a worst-case emissions scenario…”

You had no idea ?

Just conduct a simple thought experiment.

As you know, Fossil Fuels were laid down in Earth history when conditions were perilous to plant and animal life, which then died and got laid down in the strata, and chemically altered into Coal, Natural Gas and Petroleum Oil.

This process sequestered enormous quantities of Carbon in the Earth’s crust, keeping it out of the air.

As soon as mankind got out their shovels and started mining Fossil Fuels, we started to burn that Carbon right back out into the Atmosphere.

Naturally, putting all that Carbon in the sky again risks putting the Earth system back to where it came from : rather hot and dangerous to life.

  1. Oh so the fact that Volcanoes spew out more CO2 than we humans do and that CO2 is a vital component in plant photosynthesis and animal respiration is all insignificant twaddle to someone like you who does not want to be confused by the facts because their mind is made up!

    Ask an Anaesthetist what happens when your pCO2 levels drop!

    I came across your rather silly and vindictive little blog by way of someone who thought your arrogant assumptions, aggressive manipulation of the truth and insistence that anyone who dares to ask questions is a “denier”, is just so typical of the state of so called Climate Science it this point in time.

    A sceptic wants the truth and is simply sceptical of the spin spun by the Alarmists such as yourself. People can see that. The comments that you posts generate indicate that. Alarmists want the truth suppressed so that they can get that disaster porn type rush of believing that we are on the very edge of a disaster! The only disaster we have is your digging a bigger and bigger hole for yourself.

    When you are in a hole – good idea to stop digging.

    You were doing so well up until that point.
