GrandpaDave,
A newspaper article 88 years ago made an over-exaggerated claim based on spurious (seemingly anecdotal) evidence, that sure disproves climate science! Thread over! What exactly are you trying to say?
Arctic sea ice was shrinking before we really started putting CO2 into the air? Look at the actual data from the Kinnard et al 2011 graph, there is a stark decline in Arctic sea ice extent around 1980 (and even more so since 1995).
That climate has changed before? For the umpteenth time, yes climate changes naturally (usually in response to orbital cycles), slowly over
10,000’s of years. Furthermore, solar activity has been in decline since about 1950 (amplitude of 11-year cycles is decreasing) but temperatures have increased. So if it was “natural” we should have been cooling, not warming since that point.
That newspapers tend to over exaggerate things to sell papers? No argument there, hence why I prefer peer-reviewed articles.
beej67,
1) I agree there is still some uncertainty, that’s why you don’t rely on one model but an average of multiple models. And where does the average lie? Pretty darn close to that of observations (note these models do not include corrections for aerosols, ENSO and volcanoes, they are as is from FAR, SAR and TAR).

2) You didn’t hear about the mass protests over pollution in China? This is primarily a concern with aerosols but also affects CO2 emissions as well. There is great unrest over this issue and it is likely pushing China into action. You already see some signs of this: China invests more money into renewable than any other country.
Also, I’ve also stated that tariffs on imports from countries that do not have CO2 emission programs is likely an effective strategy to push countries to adopt these practices. If North America and the EU can start, it will put a lot of pressure on the reset of the planet to follow.
Finally, no one is talking about a one-world government, so why are “skeptics”? The UN won’t control the world if climate emission reduction measures are enacted, it’s absurd. Neither will the world crumble into economic turmoil. BC has seen an increase in GDP on par with Canada. EU, while still suffering from the global financial crisis which has no discernible link to its emission reduction measures, is still very competitive on the international scene. Studies that I have seen, except for one or two exceptions that “skeptics” cling to (usually originating from places like GWPF and CATO), demonstrate that mitigation is financially more viable than adaptation (I linked a bunch previously). There is simple nothing to back up the claims of political or economic collapse as a result of emission reduction measures. They come from purely from a gut reaction based on ideological rejection to more government intervention. But, guess what, saying “I don’t like that” is not a valid argument.
3) What does that local map have to do with global variations in energy accumulation on the planet, which is the concern? I recommend reviewing my post at 16 Jan 14 1:20 at the
thread here. As your particularly interested in data from back to ~1850, I’ll repost the sea level image (from NOAA):

4) likewise
5) So what’s your point? Glaciers will continue to recede very slowly without anthropogenic warming, where they recede much faster with it? Sure, I’ll agree with that but it does nothing to put into question anything related to the anthropogenic climate change theory. (Also, I’ve discussed Antarctic sea ice growth in the post I linked above)
Again, I’d like to revisit what your point is because I’m still unclear.
That it was warming before the IR, so it must be natural? The first part is true but it was very minimal warming over a long period of time, making the leap in logic to the conclusion in the second part a fallacy.
That it was warming before the IR, so even if we reduce our emissions to pre-IR levels, we won’t solve the problem? Same issue as before. The extent of the warming if we hold CO2 at 350 ppm (which was the 1980 level, not the pre-IR levels of 290 ppm) is considered by many climate scientists to result in minimal environmental impacts. Furthermore, since CO2 is removed from the atmosphere naturally, with reforestation and major reductions in CO2 consumption, it is very possible to hold at 350 ppm.
China, India, Russia, etc won’t play along with, so any mitigation measures are meaningless? Here both sides of the statement are false. If North America and EU enact measures, it will put serious political and economic pressure on the rest to follow suit. Furthermore, there is no evidence to suggest that such measures, even without global cooperation, would have major adverse effects on the global competitiveness of countries that enact them.
