more temperature estimates - with data provided at end of article http://wattsupwiththat.com/2009/10/...d-correlations-temperature-co2-and-sea-level/
I'm not sure who was recording temperature data during the Holocene period, but let's call him "Ugh." Anyway, your graph is out of date and incorrect. It is now known that conditions at this time were probably warmer than today, but only in summer and only in the extratropics of the Northern Hemisphere. This summer warming appears to have been due to astronomical factors that favoured warmer Northern summers, but colder Northern winters and colder tropics, than today (see Hewitt and Mitchell, 1998; Ganopolski et al, 1998). The best available evidence from recent peer-reviewed studies suggests that annual, global mean warmth was probably similar to pre-20th century warmth, but less than late 20th century warmth, at this time (see Kitoh and Murakami, 2002).
I'm not sure what you're talking about, but if you'd like to discuss tariffs versus income taxes that's fine. It's my opinion that a reasonable tariff level is not harmful to an economy, and in fact I would argue that granting China most favored nation status (or whatever it was) and thus reducing tariffs has been a net negative for the economy and the manufacturing areas. Having said that, I believe that free trade between countries of similar sizes and income distributions can be very beneficial, however free trade between dissimilar countries (for example where one industrial worker makes pennies a day) is harmful overall to the richer country.
You'll have to remind me what we're talking about, as your comment seems to make no sense in this context.
just for the record what did you mean by recorded history? the info I read disputes your 2002 quote... but I will go see how it is supported.
Well I was referring to temperature recording, but even in the broad general sense global temperatures have never been higher even since the first caveman scrawled a picture of a moose on a cave wall. (Is 12,000 years ago considered "recorded history?" I don't think so.)
This one of the longest term charts we can make shows we are still in the cold stages of the earth cycles. http://upload.wikimedia.org/wikipedia/commons/1/1b/65_Myr_Climate_Change.png The intermediate portion of the record is dominated by large fluctuations in the mass of the Antarctic ice sheet, which first nucleates approximately 34 million years ago, then partially dissipates around 25 million years ago, before re-expanding towards its present state 13 million years ago. These fluctuations make it impossible to constrain temperature changes without additional controls. Significant growth of ice sheets did not begin in Greenland and North America until approximately 3 million years ago, following the formation of the Isthmus of Panama by continental drift. This ushered in an era of rapidly cycling glacials and interglacials (see figure at upper right). http://commons.wikimedia.org/wiki/File:65_Myr_Climate_Change.png
finally - still waiting for the explanation of why the ice cores show that temperature precedes C02 accumulation. Also note on the chart above - they show that we are cycling more quickly now. Again - though it seems that this is much older than the industrial revolution.
Whether we're discussing recorded temperatures or recorded history, temperatures have not been higher during that period. If you go back millions of years, then temperature has been higher, but then so have the oceans which would mean drowned people, higher seas during storms and reduced land mass, which are all things that modern humans don't want to see.
1. Note - this is a headline regarding the ice cores "Holocene volcanic history as recorded in the sulfate stratigraphy of the European Project for Ice Coring in Antarctica Dome C (EDC96) ice core" 2. If man is causing the warming with CO2 accumulation? How come the ice core records show warming precedes CO2 accumulation?
