SubscribeThe Guardian reports that scientists are bewildered by sharp rise of CO2 in atmosphere for second year running.
If this is true it has dire potential consequences for our planet. Time to move to high and cooler ground.

Last night we attended one of the 8th Anniversary parties for The Guvernment, a nightclub in Toronto. Playing at the party was perhaps one of the worlds best psytrance musicians, Infected Mushroom.
Now, I’m not a huge fan of the club scene – too crouded, people with poor attitudes, etc., but(!) the music was GREAT. Especially Infected Mushroom’s set from midnight to 1:30am. These guys really know how to put music together and play a crowd.
Kim, Dave and I had a very very good time. A big thanks to Susan who gave us the tickets for my birthday. Yay Susan, you rock! Hopefully next time you can come out and play too.
Dave has been talking about wanting to build a pyramid, similar to our dome, for dance events, etc. I think it’s a cool idea and so I started doing the math behind the structure.
The idea is to build a pyramid structure out of short segments of ABS pipe and join the ABS segments together with larger diameter segments of ABS that are bound to the plastic skin of the structure.
The flat parts of the structure are pretty simple: at the joints there is a horizontal joint and 2 diagonal ones that continue the triangle shape up the side of the structure. The places that the pyramid requires a little thought is the edges between the faces and the peak.
At the edge seams, there needs to be one joint that connects a line of ABS from the corner of the base to the peak. There is another joint that carries the horizontal line from one face onto the next. Finally, the 3rd joint connects one triangle from one face to another triangle on the other. This was the angle I needed. This is also the angle from the peak of the pyramid.
