How to Talk to a Climate Skeptic
A Complete list of articles responding to the talking points circulated by the Global Warming Denialists:
"How to Talk to a Climate Skeptic," a series by Coby Beck, contains responses to the most common skeptical arguments on global warming.
There are four separate taxonomies; arguments are divided by:
Stages of Denial,
Types of Argument, and
Levels of Sophistication.
The full linked set is at Gristmill, but here is a flavor of all the subjects covered:
Stages of Denial
1. There's nothing happening
a. Inadequate evidence
There is no evidence
One record year is not global warming
The temperature record is simply unreliable
One hundred years is not enough
Glaciers have always grown and receded
Warming is due to the Urban Heat Island effect
Mauna Loa is a volcano
The scientists aren't even sure
b. Contradictory evidence
It's cold today in Wagga Wagga
Antarctic ice is growing
The satellites show cooling
What about mid-century cooling?
Global warming stopped in 1998
But the glaciers are not melting
Antarctic sea ice is increasing
Observations show climate sensitivity is not very high
Sea level in the Arctic is falling
Some sites show cooling
c. No consensus
Global warming is a hoax
There is no consensus
Position statements hide debate
Consensus is collusion
Peiser refuted Oreskes
Thats only the first 10%. At Gristmill, the list is quite exhaustive, and is fully linked and cross referenced . . .

One Third of Sun-like Stars Have Earth-Sized Planets
About a third of all the Sun-like stars in our galaxy harbor modestly sized planets, according to a study announced Monday by a team of European astronomers.
At a meeting in Nantes, France, Michel Mayor of the Geneva Observatory and his group presented a list of 45 new planets, ranging in mass from slightly bigger than Earth to about twice as massive as Neptune, from a continuing survey of some 200 stars.
All of the planets orbit their stars in 50 days or less, well within the corresponding orbit of Mercury, which takes 88 days to go around the Sun, and well within frying distance of any lifelike creatures.
Among the bounty is a rare triple-planet system of “super-Earths” around the star HD 40307, about 42 light-years away in the constellation Pictor. The planets are roughly four, seven and nine times the mass of Earth and have orbital periods of 4, 10 and 20 days, respectively.

50 Things Everyone Should Know
Warning: Huge time suck:
1.Build a Fire – Fire produces heat and light, two basic necessities for living. At some point in your life this knowledge may be vital.
7. Tell a Story that Captivates People’s Attention – If you can’t captivte their attention, you should probably just save your breath.

Found: Missing Matter
Astronomers have found some matter that had been missing in deep space and say it is strung along web-like filaments that form the backbone of the universe.
The ethereal strands of hydrogen and oxygen atoms could account for up to half the matter that scientists knew must be there but simply could not see, the researchers reported on Tuesday.
Scientists have long known there is far more matter in the universe than can be accounted for by visible galaxies and stars. Not only is there invisible baryonic matter -- the protons and neutrons that make up atoms -- but there also is an even larger amount of invisible "dark" matter.
Now about half of the missing baryonic matter has turned up, seen by the orbiting Hubble space telescope and NASA's Far Ultraviolet Spectroscopic Explorer, or FUSE.
