This page is about the Main Law Earths Temperature Through History
Temperature on Earth during the Interglacial periods was dominated (“Main Law Interglacial”) by following interdependent “actors”:
- The “stable value” of CO2 in Earths Atmosphere establishing a comfortable Insulation-Blanket.
- Fluctuations of CO2/Methane warming or cooling Earths Atmosphere.
- Increase or decrease of Ice-caps
- Earth Obliquity; shift of Earths Axis provoking Cooling-Down or Warming-Up Earths Climate.
Off course “The Main Law Interglacial” still dictates Climate in latest Interglacial-period (starting 11.500 years ago) called the Holocene in which we could live now but…
Since entrance of mankind a new “actor” entered on Earths Stage: Landscape Changes/Land Degradation by mankind.
Not surprisingly the relative mild climate conditions of the Holocene served growth of mankind so about 6.000 the influence of mankind on Earths Landscape became visible: wide scale of Deforestation/Land degradation all over Earth. Holocene ended “making way for” The Anthropocene. The Age of Mankind” entered on Earth’s stage…
As we know already Forests Cool Earth Atmosphere so Deforestation Warms Earths Atmosphere.
Paleo-Climatic research sources helps us to describe the following mechanism called “Main Law Anthropocene”:
Growth of population > Deforestation/land Degradation > Warming of Earths Atmosphere > Moderate increase of CO2-levels in Earths Atmosphere but in boundary of comfortable insulating CO2-blanket
Decrease of population (epidemics/war) > Reforestation/Land Regeneration > Cooling Earth Atmosphere > Moderate Decrease of CO2-levels but in boundary of comfortable insulating CO2-blanket.
In the early Middle Ages a new veil actor entered Earths stage: Mankind created Climate Instability by Warming Earths Atmosphere.
Now not only Paleo-Climatic research sources but also historic written records help us to describe the following mechanism called “Main Law Middle-Age Warm Period” (MWP):
Sharp Growth of Population > Forest (wood products) driven Economy > Large Scale Deforestation/Land Degradation in short time > Interruption of Biotic-Pump > Rapid Warming of Earths Atmosphere > Climate Instability but the Moderate Increase of CO2-levels in Earths Atmosphere stay within the boundary of comfortable insulating CO2-blanket.
A long period of Climate Instability (extreme cold winters and summers/extreme warm winters and summers, extreme wet springs and summers/extreme dry springs and summers) called “The Little Ice-Age” followed the MWP wreaking havoc on mankind by crop failure, hunger and related “events as social disruption, conflicts and epidemics.
Paleo-Climatic resources and written records help us to describe the following mechanism called “Main Law Little Ice Age” (LIA):
Sharp Decrease of Population > Forest (wood products) driven Economy > Slow Reforestation/Land Regenaration by nature > Re-establishing of Biotic-Pump > slowly Cooling of Earths Atmosphere > Cooling and Stabilizing Earths Atmosphere with a Moderate Decrease of CO2-levels in Earths Atmosphere staying within the boundary of comfortable insulating CO2-blanket.
Beginning of 19th century Earth stage faced the results of mankind’s innovation capacity: the development of Fossil-Propelled machinery; begin of the Fossil Driven Economy which lasts until now and results in sharp rise of CO2-Levels Warming-up Earths Atmosphere so beyond the boundary of comfortable insulating CO2-blanket.
But the Fossil Driven Economy is still combined with a Forest-Driven Economy. Forests are still abused for leverage of goods resulting in constant Deforestation/Land Degradation.
Scientific research sources helps us to describe the following mechanism called “Main Law Industrial Revolution to Now”:
Sharp Growth of Population > Forest & Fossil driven Economy > Large Scale Deforestation & Land Degradation in short time > Interruption of Biotic-Pump > Rapid Warming of Earths Atmosphere > Rapid and Increasing Climate instability by Sharp raising CO2 Levels in Earths Atmosphere > CO2 Greenhouse Blanket > Climate Instability > Rise of New Climate Change driven Conflicts…..
So what to do now?
The sequential Main Laws MWP /LIA/ Industrial Revolution to Now show us that mankind has a large Fingerprint on Earths Climate and the fact that by provoking Climate Instability mankinds’ safety is put at the stake such as we can derive form History/Main Laws MWP and LIA.
A report, released by a Pentagon think-tank in 2001, describing dangers of Climate Instability was received as a “doom Prophecy” but science and recent events (Syrian civil war provoked by severe droughts between 2006-2010) show us the validity of the report.
With safety of mankind at the stake we must acknowledge that not “Mother Earths Health” ( a romantic simplification) is the key-problem because the Main-Laws MWP/LIA show us that Mother Earth recovers by Natural Re-Greening Stabilizing Earths Atmosphere/ Earths Climate after large percentage removal of human population.
Beware! Earth is adaptive to our mismanagement. It simply shifts towards a new equilibrium when we destroy it’s existing equilibrium!
But mankind/society is far less adaptive…
