The Positive Impact of Human CO2 Emissions on the Survival of Life on Earth

This study looks at the positive environmental effects of carbon dioxide (CO2
) emissions, a topic which has been well established in the scientific literature but which is far too often ignored in the current discussions about climate change policy.
All life is carbon based and the primary source of this carbon is the CO2
in the global atmosphere and hydrosphere.
As recently as 18,000 years ago, at the height of the most recent major glaciation, atmospheric CO2
dipped to its lowest level in recorded history at 180 ppm, low enough to stunt plant growth. This is only 30 ppm above a level that would result in the death of plants due to CO2
It is calculated that if the decline in CO2
levels were to continue at the same rate as it has over the past 140 million years, life on Earth would begin to die as soon as two million years from now and would slowly perish almost entirely as carbon continued to be lost to the deep ocean sediments.
The combustion of fossil fuels for energy to power human civilization has reversed the downward trend in CO2
and promises to bring it back to levels that will foster a considerable increase in the growth rate and biomass of plants, including food crops and trees.
Human emissions of CO2
have restored a balance to the global carbon cycle, thereby ensuring the long-term continuation of life on Earth.
This extremely positive aspect of human CO2
emissions must be weighed against the unproven hypothesis that human CO2
emissions will cause a catastrophic warming of the climate in coming years.
The one-sided political treatment of CO2
as a pollutant that should be radically reduced must be corrected in light of the indisputable scientific evidence that it is essential to life on Earth.

This paper will change the way you understand the carbon cycles, climate change and the human influences in those processes. Highly recomendable.
The political reports of the IPCC are based on the hypothesis that CO2
is the most important control knob of the Earth's temperature. The problem is that this hypothesis does not correspond at all with the empirical data available to science. Forecasts are made using models that are not capable of 'predicting' the past
When discussing “Climate Change” it’s good to have an understanding of how the Earth’s climate has changed in the past. That will give us a reference in order to decide of the current changes are normal or not.
Global temperatures have varied a lot over the last 500 million years. Depending on the timescale used, the current temperature is either cold or hot, so when you want to know the “normal temperature” you’ll have to indicate what timescale you’re using.
This must be the environmental myth with the deepest roots of them all (pun intended). It's compulsory subject matter in public schools around the globe, it's passed from generation to generation and if you dare to question it in public, disbelieve, rejection, jeering and even exclusion from the conversation will be your treat. That's the typical way people react when their beliefs and primary "knowledge" are challenged.
Woods, forests and jungles are Earth's "Green Lungs" that generate and produce the oxygen we need to breath and live.
Last month, the New York Times website published a page titled "Glaciers Are Retreating. Millions Rely on Their Water."
It shows a dramatic image, zooming out of a person walking down a dry glacier bed with the following text:
"In Central Asia, a warming climate is shrinking the Tuyuksu glacier. It’s losing ice every year.
Around the world, vanishing glaciers will mean less water for people and crops in the future."
Computer models are something magical. As powerful computers, located at famous universities and authoritative government agencies are involved, model output is often considered to be a substitute for reality
But it's not.
Since the start of the Global Warming scare numerous predictions have been made about all kind of things related to the climate. As this scam is going on for over 30 years now some of those predictions have reached their due date and the time has come to check the results.
