I just wanted a place to keep handy links to debunk common misconceptions.

Global Warming

Volcanoes produce more CO₂ than humans

Turns out the USGS has an artice on that one here.

Gas studies at volcanoes worldwide have helped volcanologists tally up a global volcanic CO₂ budget in the same way that nations around the globe have cooperated to determine how much CO₂ is released by human activity through the burning of fossil fuels. Our studies show that globally, volcanoes on land and under the sea release a total of about 200 million tonnes of CO₂ annually.

This seems like a huge amount of CO₂, but a visit to the U.S. Department of Energy's Carbon Dioxide Information Analysis Center (CDIAC) website (http://cdiac.ornl.gov/) helps anyone armed with a handheld calculator and a high school chemistry text put the volcanic CO₂ tally into perspective. Because while 200 million tonnes of CO₂ is large, the global fossil fuel CO₂ emissions for 2003 tipped the scales at 26.8 billion tonnes. Thus, not only does volcanic CO₂ not dwarf that of human activity, it actually comprises less than 1 percent of that value.

Human Embrionic Stem Cells

Adult stem cell therapy exists, embrionic stem cell therapy does not

Turns out there's some promise in human embrionic stem cells. You can even start new lines without destroying the fetus (which was probably going to be destroyed anyway.) RPE therapy.
