The ice caps are melting on Mars too.

Martian climate is primarily driven by dust and albedo and there is little empirical evidence that Mars is showing long term warming.

We should drill in ANWR.

http://www.anwr.org/features/pdfs/ANWR_estimates.pdf
median estimate of technically recoverable reserve - 10.3 billion barrels

That figure is provided by the ANWR drilling lobbyist group, Arctic Power.

ANWR is estimated to have a 30-50 year production lifespan. If the mean of 40 years is taken, ANWR production (~700 thousand barrels/day) would account for 3.4% of current (2005) US oil consumption.

As Brian H put it, “a short-term, expensive, and relatively trivial source.”

CO2 has about 5% of the influence of water vapour in the atmosphere.

http://skepticalscience.com/water-vapor-greenhouse-gas.htm

Water vapour is indeed the most dominant greenhouse gas. The radiative forcing for water is around 75 W/m2 while carbon dioxide contributes 32 W/m2 (Kiehl 1997). Water vapour is also the dominant positive feedback in our climate system and a major reason why temperature is so sensitive to changes in CO2.

Unlike external forcings such as CO2 which can be added to the atmosphere, the level of water vapour in the atmosphere is a function of temperature. Water vapour is brought into the atmosphere via evaporation - the rate depends on the ocean and air temperature and is governed by the Clausius-Clapeyron relation.

If extra water is added to the atmosphere, it condenses and falls as rain or snow within a week or two. Similarly, if somehow moisture was sucked out of the atmosphere, evaporation would restore water vapour levels to ‘normal levels’ in short time.

geologically, CO2 spikes TRAIL global temperature spikes by about 800 years

The CO2 record confirms both the amplifying effect of atmospheric CO2 and how sensitive climate is to change.

I don’t have a “just in case” position. I have a “look at all the science, not just that which supports your preconceived notions” position. The skepticalscience.com site backs up all of its articles with peer-reviewed research papers.

As has recently been revealed, peer review is highly fallible, as huge %‘s of fudged findings are getting through.  Not to mention its inherently consensus-reinforcing tendencies.
Here’s some dissenting analysis that had a hard time getting past the group-think filter:

Maybe it’s the tachyons?

The graphs of rising temps in the last few decades suddenly switch slope when the data from sensors being engulfed by urban heat island sprawl are excluded.

Please reference this claim.

http://skepticalscience.com/urban-heat-island-effect.htm

(Peterson 2003) did statistical analysis of urban and rural temperature anomalies and concluded “Contrary to generally accepted wisdom, no statistically significant impact of urbanization could be found in annual temperatures… Industrial sections of towns may well be significantly warmer than rural sites, but urban meteorological observations are more likely to be made within park cool islands than industrial regions.”

Another more recent study (Parker 2006) plotted 50 year records of temperatures observed on calm nights, the other on windy nights. He concluded “temperatures over land have risen as much on windy nights as on calm nights, indicating that the observed overall warming is not a consequence of urban development”.

Surfacestations.org are compiling photographs of US weather stations photographs to demonstrate the unreliability of surface temperature measurements. Photos are an anecdotal way to do science - the only way to quantify the impact of urban heat island is to analyse the data from these stations. This is what GISS have done, with their methodologies and data freely available online.

If Urban Head Island effect was exacerbating global warming records, there would be a correlation between urbanisation and warming. Instead, the regions of the globe with greatest temperature rise seem to be anywhere but the urbanised regions.

For those of you getting increasingly worried about the end of Man Made Climate Change - don’t panic. If FF does provide unlimited affordable clean power to the world (please God) there are plenty of clever people out there who will find something else for us to be guilty of.

The crisis-concocting AGW-panic exploiters will be homeless.  Perhaps a special welfare fund will be established for them, including huge special residential complexes where frequent unannounced fire and Carbon Monoxide evacuations will be called to keep them excited and interested (not all drills; a certain minimum fatality rate to be ensured to sustain realism.)
