Can we make your blood 0.04% cyanide if you think low percentages are some how important ?

you knows whats crazy you see stuff like this
- A well-documented record of global temperature shows that we have been in a major cooling period since the Eocene 50 million years ago. The Earth was an average 16C warmer then. Antarctica was ice free and covered in forest. The ancestors of every species on Earth today survived through what may have been the warmest time in the history of life. But today we hear predictions of disaster with a 2C rise! Glaciers began to form in Antarctica 30 million years ago and in the northern hemisphere 3 million years ago. Today, even in this interglacial period of the Pleistocene Ice Age, we are experiencing one of the coldest climates in Earth history.
From Antarctic ice cores for the past 800,000 years there have been glacial cycles in 100,000 year-cycles coinciding with with the Milankovitch (eccentricity of the Earth's orbit and its axial tilt). There is a strong correlation between temperature and the level of atmospheric CO2 during these successive glaciations, indicating a possible cause-effect relationship between the two. CO2 lags temperature by an average of 800 years during the most recent 400,000-year period, indicating that temperature is the cause, as the cause never comes after the effect.
It is sobering to consider the magnitude of climate change during the past 20,000 years, since the peak of the last major glaciation. At that time there were 3.3 kilometres of ice on top of what is today the city of Montreal (3 million people). If the Milankovitch cycle continues to prevail, this will happen gradually again during the next 80,000 years. Will our CO2 emissions stave off another glaciation?
Water is by far the most important greenhouse gas, and is the only molecule that is present in the atmosphere in all three states, gas, liquid, and solid. IPCC said this in 2007, "we should recognise that we are dealing with a coupled nonlinear chaotic system, and therefore that the long-term prediction of future climate states is not possible." Now they claim they can predict it!
Plants, including trees and all our food crops, are capable of growing much faster at higher levels of CO2 than present in the atmosphere today [slide (at 24:35) shows greenhouse demonstration]. Even at today's concentration of 400 ppm plants are relatively starved for nutrition. The optimum level of CO2 for plant growth is about 5 times higher. CO2 is the giver of life. We should celebrate CO2 rather than denigrate it as is the fashion today.
Beginning 540 million years ago many marine species of invertebrates evolved the ability to control calcification and to build armour plating to protect their soft bodies. Shellfish such as clams and snails, corals, phytoplankton, and zooplankton began to combine carbon dioxide with calcium and thus to remove carbon from the life cycle as the shells sank into sediments. The white cliffs of Dover are made of their calcium carbonate skeletons. The amount of CO2 in the atmosphere was reduced by about 90% during the last 150 million years. If this trend continues CO2 will inevitably fall to levels that threaten the survival of plants, which require a minimum of 150 ppm to survive. If plants die all the animals, insects, and other invertebrates that depend on plants for their survival will also die.
How long will it be at the present level of CO2 depletion until most or all of life on Earth is threatened with extinction by lack of CO2 in the atmosphere? If humans had not begun to unlock some of the carbon stored as fossil fuels, less than 2 million years from today! Human emissions of carbon dioxide have saved life on Earth from inevitable starvation and extinction due to lack of CO2.
Let us have no hominem arguments about "deniers". I submit that much of society has been collectively misled into believing that global CO2 and temperature are too high when the opposite is true for both.
Even when the fossil fuels have become scarce, we have the quadrillion tons of carbon in carbonaceous rocks, which we can transform into lime and CO2 for the manufacture of cement using solar energy or nuclear energy. The human species has made it possible to prolong the survival of life on Earth for more than 100 million years. We are not the enemy of nature but its salvation!
and it's hosted at stanford university are they insane?
someone should cancel them for hosting this dangerous infomation

HUH? not sure where you coming from, but give it a go yourself and let us know how it works out.

That article was based on a lecture by Patrick Moore. He has a reputation for being a hired gun for the PR departments of the fossil fuel, logging, nuclear, GMO crop industries and using his former senior membership of Greenpeace (he left in 1986) as a way to give himself environmental credibility.
In 2020 he wrongly claimed that there is no scientific evidence that increased atmospheric CO2 concentrations contribute to climate change.
George Monbiot analysed Moore's work with the Indonesian logging firm APP. Moore was hired as a consultant to write an environmental 'inspection report' on their operations. However, Moore's company is not a monitoring firm and the analysts used were just PR experts. Monbiot has said that sections of the report were copied from an APP brochure.
French investigative journalist, Paul Moreira, interviewed Moore on French TV and asked him about the safety of the herbicide glyphosate. Moore told Moreira that one "could drink a whole quart of it" without any harm. When Moore was challenged to drink a glass of it there and then, he refused, saying "I'm not an idiot" and "I'm not stupid" before ending the interview.
I don't believe that he is honest or trustworthy on this issue.
