I'm all for free energy, Rodri. Also nice to see you again. I would like to see massive solar panels surrounding the moon or maybe we could create our own solar panel covered celestial object from materials mined from Mars and place it in orbit around the Earth. Or cold fusion, let's crack that nut.
The most reliable way of documenting past climate change is by analyzing the chemical make up of water taken from ice core samples from the poles of the Earth. Giant drills dig into ice that has been in a frozen state for hundreds of thousands of years, pull up a sample and look at what is in it. Unfortunately the farthest back in time we've been able to accurately see is something like 800,000 years.
Even though everyone says we totally disagree, we really don't. We just expressed it a little differently. We both are concerned about the same things and scared and worried and probably choose to ignore it most of the time except for situations like this where we feel the need to puff up our chests and yell at people for thinking stupid things about stuff they don't know.
You know what's funny is that exposed rocks are carbon sinks. They capture CO2 by weathering and eroding, so some of the way way out there extremists claim that we can cut down as many trees as we want and burn as much fossil fuel as we want and an increase in temperature will balance out this change in our atmosphere for us by exposing previously ice-covered rocks which will suck out just as much CO2 as all the trees we cut down to make copies of Larry Flint's Barely Legal.
