    Losing the Fear of Generating CO2

    By the way, for comparison to that deceptive temperature graph you linked, here is the UAH's website: http://nsstc.uah.edu/climate/ And here is the graph posted at their front page, which includes all of the global data: Even though though the graph is still just monthly, the warming trend is...

    Losing the Fear of Generating CO2

    Yet another example of lying with graphs. There are a few problems with this: 1. They plotted the monthly data. This causes large short-term swings in temperature to appear that hide the underlying trend. The best thing to do is to plot a 3-year or 5-year moving average. This smooths out...

    Losing the Fear of Generating CO2

    This is an example of lying with graphs. The key to why these graphs are so deceptive is at the far left, at 1983: notice that all of the models start from the exact same point, and both of the temperature records immediately drop (while half the models go up and another half go down). Roy...

    That doesn't answer the question. "Looking at Mother Nature" means performing some kind of observation. What kind of observation, specifically? Why do you think that observation means what you say it means?

    What, specifically, do you think the climate sensitivity to a doubling of CO2 is and why?

    Why do you think the existence of winter disproves global warming?

    Losing the Fear of Generating CO2

    What predictions would these be, precisely? And how did they fail? The last in-depth test of previous predictions that I'm aware of is the Copenhagen Diagnosis, which evaluated the 2000 IPCC report's predictions in 2009. The results were that the temperature predictions were spot-on, but the...

    Losing the Fear of Generating CO2

    Not if that fear is realistic. Realistic fear is not harmful: it's helpful. The dose makes the poison. Oxygen is critical for humans and other animals, for example. But increasing the percentage of the oxygen in the atmosphere would make things pretty uncomfortable for us. The total effect...

    Why? You've proven that you'll just ignore evidence that is presented to you.

    Losing the Fear of Generating CO2

    What are you talking about? The full global temperature change in that plot doesn't occur until hundreds of years after the change in CO2 concentration (this is likely because it takes hundreds of years for the oceans to mix fully). Your conclusion cannot be supported by the evidence. Prove it.

    Losing the Fear of Generating CO2

    There isn't a significant economic sacrifice, though. In fact, in the current economic climate the government's finances (in the US and Europe) would be made better-off if they borrowed money to spend on infrastructure (because the extra spending puts people who are currently out of work to...

    I believe you meant this post, as that one doesn't talk about the specific time scales at all: http://www.christianforums.com/threads/losing-the-fear-of-generating-co2.7881039/page-3#post-67998560 The answer here is simple: it takes time for the planet to respond to changes in CO2...

    Losing the Fear of Generating CO2

    Wait, what? Lower than when, specifically? What past are you referring to? Because on long time scales, CO2 is also a feedback. In particular, a warmer ocean doesn't dissolve CO2 as readily, so if something else, like the Sun, changes the temperature of the Earth, then the oceans slowly emit...

    Losing the Fear of Generating CO2

    This is not at all true. If anything, the recent warming has followed the CO2 trend more closely than in the past (because before about 1970 or so, the CO2 changes in the atmosphere were small enough that their impact was swamped by other factors). I'm aware that there have been some sources...

    Losing the Fear of Generating CO2

    It's somewhat misleading to say that CO2 has a halflife of decades. This post describes the issues: http://www.skepticalscience.com/co2-residence-time.htm The short of it is that the primary way that CO2 gets out of the atmosphere is by dissolving in the oceans, but as the upper layers of the...

    Losing the Fear of Generating CO2

    The total greenhouse effect from water is a good deal larger than that from CO2. However, the amount of water in the atmosphere is almost entirely set by temperature. The small radiative forcing from water is from the little bit of difference due to human activity (e.g. building lots and lots...

    Losing the Fear of Generating CO2

    Why do you think this? What about the Earth do you think gives it its temperature? The vertical opacity is given by the opacity per molecule of CO2 times the number of CO2 molecules per unit area in a column of air.

    Losing the Fear of Generating CO2

    The biggest smoking gun for the greenhouse effect being the primary cause of warming is the cooling of the upper atmosphere. The greenhouse effect warms by increasing the temperature difference between the lower and upper atmosphere. While the lower atmosphere is still warming, the upper...

    Losing the Fear of Generating CO2

    Climate scientists really aren't confused about what's going on with the climate. There are some uncertainties as to precisely how much warming will result from human activity, but scientists are clear about what those uncertainties are. There's really no significant disagreement on the...
