Moreover, added CO2 is an externality http://en.wikipedia.org/wiki/Externality [wikipedia.org] so individuals have no incentive to reduce the creation of CO2. This is true with pollutants in general. As with most difficult externalities, the impact of the pollution is not directly on the individual who created it, and it is diffuse enough that one cannot easily trace any specific bit of pollution back to any specific source. That's precisely why we have the government regulate the sources. Cap and trade is a very efficient system which takes advantage of market forces to more efficiently reduce pollution.

Look at all the warming across northern Canada.

And the elevated temperatures across Canada above the Arctic Circle? It's amazing how the one station at Ellesmere Island -- the only one above the Arctic Circle that NOAA collects data from -- can measure the temperature all the way across Canada.Look at NOAA's own data; in 1991, almost a quarter of NOAA’s Canadian temperature data came from stations in the high Arctic. The same region contributes only 3% of the Canadian data today. NOAA collects no temperature data at all from Bolivia -- a high-altitude, landlocked country -- but instead “interpolates” or assigns temperature values for that country based on data from “nearby” temperature stations located at lower elevations in Peru, or in the Amazon basin.
NOAA also says that Arctic sea ice was "below normal for the 11th consecutive April" while "based on NOAA satellite observations, snow cover extent was the fourth-lowest on record" since 1967."
Really? In other articles [meteorologynews.com], data collection by NOAA's own National Snow and Ice Data Center would appear to suggest otherwise. "While global sea ice extent has only been measured with high resolution since 1979, the recent increase in sea ice coverage now puts the start of 2009 in the same place as the year when records started: 1979. While the extent of sea ice in the northern hemisphere is currently slightly below the 30-year mean, the coverage in the southern hemisphere exceeds the thirty-year mean by approximately 500,000 square kilometers." Not only that, the extent of sea ice around Antarctica has been increasing over the last 20 years, a state of affairs that the current climate models are unable to explain; all the models that have been tweaked to corroborate the desired result of global warming would have warming water around Antarctica causing a long-term reduction in sea ice; the Earth failing to cooperate with rigged projections places these models in doubt.

A large increase in the incidence of thyroid cancer has occurred among people who were young children and adolescents at the time of the accident and lived in the most contaminated areas of Belarus, the Russian Federation and Ukraine. This was due to the high levels of radioactive iodine released from the Chernobyl reactor in the early days after the accident.
In Belarus, the Russian Federation and Ukraine nearly 5 000 cases of thyroid cancer have now been diagnosed to date among children who were aged up to 18 years at the time of the accident.
It is expected that the increased incidence of thyroid cancer from Chernobyl will continue for many years, although the long-term magnitude of the risk is difficult to quantify.
The Expert Group concluded that there may be up to 4 000 additional cancer deaths among the three highest exposed groups over their lifetime (240 000 liquidators; 116 000 evacuees and the 270 000 residents of the SCZs).
Predictions, generally based on the LNT model, suggest that up to 5000 additional cancer deaths may occur in this population [ Belarus, the Russian Federation and Ukraine] from radiation exposure
The numbers in this report are contested by a Greenpeace study (available here [greenpeace.org]). Greenpeace estimates the number of cancers attributable to the Chernobyl accident to 270000, out of which 93000 fatal.

I'm not sure the average was lower. I thought it was slightly higher, although not by nearly as much as expected from the higher CO2 concentration of the period, so it is still a valid question to ask. Also, what is typical of the Jurassic, Cretaceous, and early Cenozoic is not merely higher CO2, but a more "equable" climate between the equator and the poles -- less difference in temperature. Much of the difference in climate in the Mesozoic and early Cenozoic is thought to be due to different continental configuration. Continental position greatly affects ocean currents and how the temperature is distributed world-wide. For example, in the Mesozoic and early Cenozoic there was an equatorial ocean without continents blocking the E-W flow of the currents (e.g., the Pacific and Caribbean were connected, and what is now part of the Mediterranean was connected via wide straights to the Atlantic and to the west -- the Tethys Ocean [wikipedia.org]). Continental position, global sea level, and variations in erosion in mountain ranges is thought to be responsible for the long-term (100s of millions of years) cycling between conditions. Basically it is plate tectonics driving these very-long-term fluctuations. [wikipedia.org]
