ECO Myths

Here are some eco myths to think about.
Myth: The Earth is warmer than it was 100 years ago.
Truth: At most it’s risen by 0.3 Celsius, less than 0.003 degrees annually.

Myth: Global Warming must be happening, it’s warmer here in Small Town.
Truth: It is global averages that matter (see above)

Myth: Carbon dioxide levels and average global temperatures are at a record high
Truth: No, they are among the lowest determined over the last few million years.

Myth: Rising carbon dioxide levels are directly linked to rising global temperatures.
Truth: Not necessarily, there is a 400-4000 year timelag

Myth: Receding ice sheets prove anthropogenic (man made) Global Warming is happening
Truth: Some ice is melting, other areas are actually growing

Myth: Carbon dioxide is the most potent greenhouse gas
Truth: No, that would be water vapor of which there is an abundance in the atmosphere, then there is methane, and nitrogen trifluoride used in the manufacture of flat screen TVs.

Myth: If we accept it as real, we can do something about it.
Truth: We cannot even control local weather, what makes us think carbon sequestration and seeding the oceans, etc. will allow us to affect the climate. These come from a science web site.
