why would he be joking? its the great question your side can not explain.. when you understand that co2 levels follow change in ocean temps and that we don't live in a closed system you no longer wonder why there is no peer reviewed science saying man made co2 causes warming. ... co2 are mostly like just like humidity. As ocean temp go up land temps go up and humidty and co2 then go up. .
CO2 lags temperature - what does it mean? Link to this page What the science says... Select a level... Basic Intermediate CO2 didn't initiate warming from past ice ages but it did amplify the warming. In fact, about 90% of the global warming followed the CO2 increase. Climate Myth... CO2 lags temperature "An article in Science magazine illustrated that a rise in carbon dioxide did not precede a rise in temperatures, but actually lagged behind temperature rises by 200 to 1000 years. A rise in carbon dioxide levels could not have caused a rise in temperature if it followed the temperature." (Joe Barton) Earth’s climate has varied widely over its history, from ice ages characterised by large ice sheets covering many land areas, to warm periods with no ice at the poles. Several factors have affected past climate change, including solar variability, volcanic activity and changes in the composition of the atmosphere. Data from Antarctic ice cores reveals an interesting story for the past 400,000 years. During this period, CO2 and temperatures are closely correlated, which means they rise and fall together. However, based on Antarctic ice core data, changes in CO2 follow changes in temperatures by about 600 to 1000 years, as illustrated in Figure 1 below. This has led some to conclude that CO2simply cannot be responsible for current global warming. Figure 1: Vostok ice core records for carbon dioxide concentration and temperature change. This statement does not tell the whole story. The initial changes in temperature during this period are explained by changes in the Earth’s orbit around the sun, which affects the amount of seasonal sunlight reaching the Earth’s surface. In the case of warming, the lag between temperature and CO2 is explained as follows: as ocean temperatures rise, oceans release CO2 into the atmosphere. In turn, this release amplifies the warming trend, leading to yet more CO2 being released. In other words, increasing CO2 levels become both the cause and effect of further warming. This positive feedback is necessary to trigger the shifts between glacials and interglacials as the effect of orbital changes is too weak to cause such variation. Additional positive feedbacks which play an important role in this process include other greenhouse gases, and changes in ice sheet cover and vegetation patterns. A 2012 study by Shakun et al. looked at temperature changes 20,000 years ago (the last glacial-interglacial transition) from around the world and added more detail to our understanding of the CO2-temperature change relationship. They found that: The Earth's orbital cycles triggered warming in the Arctic approximately 19,000 years ago, causing large amounts of ice to melt, flooding the oceans with fresh water. This influx of fresh water then disrupted ocean current circulation, in turn causing a seesawing of heat between the hemispheres. The Southern Hemisphere and its oceans warmed first, starting about 18,000 years ago. As the Southern Ocean warms, the solubility of CO2 in water falls. This causes the oceans to give up more CO2, releasing it into the atmosphere. While the orbital cycles triggered the initial warming, overall, more than 90% of the glacial-interglacial warming occured after that atmospheric CO2 increase (Figure 2).

Hmmm.....so the earth changed orbit, temperature got hotter and CO2 concentrations went up due to positive feedback loop. So how did the CO2 concentrations and temperature go down? The temp and CO2 went up and down 4 times on that chart therefore looks like possibly a cycle. Why is it cyclical? Does the earth change orbit on a cycle?

http://www.nbcmontana.com/weather/weather-news/accumulating-snow-colder-temperatures/500728322 Accumulating snow, colder temperatures A WINTER STORM WATCH is posted Tuesday night and Wednesday for the Butte, Anaconda, Georgetown Lake, Dillon, West Yellowstone and Philipsburg. The watch also includes all passes of southwest Montana, from Lolo and Lost Trail to Monida and Bozeman. Areas between 4000 and 5500 feet will receive 2 to 6 inches of snow while above 5500 feet snowfall of 6 to 14 inches will be possible west of the divide and above 6500 feet east of the divide.
http://www.heraldandnews.com/news/l...cle_b7696176-5506-5976-9ea6-b94de8543f64.html A winter weather advisory for snow was issued by the National Weather Service for today and tonight, according to a news release. The advisory was reported to be in effect from 11 p.m. Monday until 8 p.m. tonight and forecasts snow accumulations from 3 to 6 inches above 5,500 feet elevation, except higher amounts of 6 to 10 inches above 6,000 feet near Crater Lake. Affected locations also include higher portions of highways 62, 230, 138 and 58 in the Southern Oregon Cascades and the Mount Ashland ski road in the Siskiyous. Snow levels will lower further down to 4,000 feet this evening but little accumulation is expected for locations below 5,500 feet.
did you see what the articles said. Ocean temps rise then co2 gets released. exactly what the more recent peer reviewed humlum paper also shows on a shorter time frame. Co2 levels trail warming. the guess work in your article is that co2 amplifies warming. We discussed that Shakun paper back when it was written. that is nothing new. here is a more recent paper... showing that in recent times... co2 still lags changes in ocean temps. http://www.sciencedirect.com/science/article/pii/S0921818112001658
