Climate Science
  • Skeptical Science -- Actually not a climate skeptic website.  It's a climate activist website, refuting just about every climate skeptic argument imaginable.  Terrific resource.  On many issues, it has "basic", "intermediate", and "advanced" answers, and if even the "advanced" answer isn't satisfying, there are blog entries following the answers where fairly sophisticated, intelligent people are discussing the matter in even more detail.
  • NOAA Global Climate at a Glance -- This website allows one to plot global temperature data since 1880, averaged over time spans ranging from one month to 5 years.  NOAA is the national agency for weather prediction, they run the weather satellites.  The website also allows one to plot temperature for the US, or for any state, or for many cities.  Very informative, especially when discussing the false claim frequently made by climate skeptics that global temperatures haven't risen since 1998.
  • Berkeley Earth The organization formed by Berkeley physics professor Richard A Muller when he did an exhaustive study re-creating the temperature record.

Carbon-Free Energy
  • Stanford Professor Mark Z. Jacobson's Plan for 100% carbon-free energy in the US by 2050, with no nuclear (132 pages).  It involves getting energy mostly from solar, wind, hydro, and geothermal, and using hydro for energy storage for windless nights.  Pretty much every suitable hydro site in the country has already been dammed, and Jacobson realizes this.  For energy storage, we'll need an order of magnitude more dam turbines than we have, and the proposal is to add more turbines to existing dams, including many irrigation dams that currently don't have any turbines on them.
  • Nuclear Energy
  • Lifetime Emissions by Energy Type This is net warming caused by the emissions of CO2 and CH4 (methane) due to the creation of the energy consumed by one person in their lifetime.
  • Cost per MWh by Energy Type Note that when the cost of wind and solar are calculated, they usually aren't factoring in the expense of either storing the energy for windless nights, or keeping a backup supply from some other source on standby.

Vegetarian Policy

Sometimes we get vegans demanding that we stop serving pizza with cheese on it to anybody. Vegans are welcome in this group and we get vegan pizza for them, but preaching to others about their diet will not be tolerated.
