The problem with simple physics on the lab bench is that it ignores oceans, clouds, earth orbits and spin, changes in solar radiation, outer space, gravitational effects and constant volcanic activity in the oceans. Only simple minded scientists would present such simple physics and only simple minded peers and research publications would hold such experiments up as models for global warming. How true! And because it seems to be "obvious" that increases in atmospheric "greenhouse gasses" would cause an increase in the temperature of the world, there has never been any attempt to quantify such an effect and all the guestimates rely on un-demonstrated "amplification" effects without ever considering there are also compensating negative feedbacks active at the same time... It is just as obvious that peeing in the ocean MUST raise the ocean levels all over the world, but don't expect that you will flood Holland by doing it....

There is another variable that is never brought into the equation. That is earth's own magnetic field. And it is becoming weaker. I'd like to see a study on climate patterns compared to the strength and orientation of the earth's magnetic field. Magnetic Shield Earth's geodynamo creates a magnetic field that shields most of the habited parts of our planet from charged particles that come mostly from the sun. The field deflects the speeding particles toward Earth's Poles. Without our planet's magnetic field, Earth would be subjected to more cosmic radiation. The increase could knock out power grids, scramble the communications systems on spacecraft, temporarily widen atmospheric ozone holes, and generate more aurora activity. news.nationalgeographic.com Current records suggest that we are long overdue for our next reversal, he said. "On average, there is a reversal around every 400,000 years, but this varies a lot." The geological record suggests that the last reversal was around 800,000 years ago. Furthermore, there is already evidence to show that the field has been weakening over the last few centuries – some archaeological remains suggest that the field was far stronger in the time of the Roman Empire, some 2,000 years ago. cosmosmagazine.com
