Here's more examples showing how current CO2 levels are quite low; they are very mild.

Folks who listen only to main stream media may get the idea that the current levels of CO2 are dangerously high--WRONG. And there's even false reports that crop yields may decline-- NOPE. Also alleging that CO2 is a dangerous pollutant-- ITS NOT Implying that current levels are unprecedented-- VERY FALSE

But when looking into the scientific history, all those false reports are debunked. Actually there could be a doubling, tripling, even quadrupling and still be well within historic levels. Current levels average about 420 ppm, and even if quadrupling would be well below 2,000 ppm.

Acceptable levels in meeting rooms and classrooms are 1,000 to 1,100 ppm. And the standard for naval submarines is 5,000 ppm.

Here's a historic chart of CO2 levels over the eons. This supports the idea often mentioned by climate skeptics pointing out how current levels are quite low.

Image Info: Current CO2 levels are very low, compared with historic levels.

This 3 min. video by Scientist Greg Wrightstone explains that CO2 is not dangerous to mankind.

Here's a chart showing prior warming periods, which all exceeded the current summer's temperatures

Here's some further examples showing the benefits of increased CO2 levels.

Image Title: CO2 boosts tree growth
Image Info: This demonstration shows how commercial greenhouse operators boost the growth of their plants and trees. Notice the amounts of CO2 being added to green houses, from +150 to +450 ppm vs only the amounts from the AMBIENT air. Click Here

Quotes: "An additional significant benefit from this increasing CO2 fertilization is that the plants have smaller stomata (pores) and have lessened water needs. Less water used means that more stays in the ground and is leading to increasing soil moisture across much of the planet and a “greening” of the Earth. According to NASA, up to 50% of the Earth is “greening,” in part due to higher CO2 levels." . . . " During nearly all of Earth’s history, carbon dioxide concentration was at many multiples of our current level, averaging 2,600 ppm, or 6.5 times our current measurement.

Image Title: CO2 boosts crop yields Image Info: Studies have shown that increased CO2 levels are stimulating crops needed for increasing global populations.
