Don't you agree that the sun is at least
one of the forces responsible? I hear what you are saying, but I respectfully disagree. The sun's activity varies over time. . . someday it will expand and swallow the Earth to the point where we'll
all have to move to another planet. . . granted that won't be for awhile.
The data in the graph is inconclusive:

Overall, the committee believes that Mann’s assessments that the decade of the 1990s was the hottest decade of the millennium and that 1998 was the hottest year of the millennium cannot be supported by his analysis

However, I aknowledge that this debate seems to be ongoing, and there are no final conclusions. . . I'm just saying that we should not draw our
own conclusions based on the graph which you cited. There's a lot that we
don't know, and hopefully, time will sort it all out. . .

I should also say this: the global temperature is not increasing at the same rate everywhere in the world. In land areas, the temperature increase has been greater than over oceans. The temperature increase is especially high over the north and south poles. This means that although the average temperature change may be low, not every place on Earth has experienced such a low change. For most places that people actually live, the change has been high.
Further, this temperature change of less than one degree Celcius is not the real problem. The problem is that scientists think the change is caused primarily by increases in carbon dioxide, and the carbon dioxide in our atmosphere is already very high and is only going to keep increasing. So if they are correct, then future temperature increases will be higher than this.

Hence, the reason I posted my own graph. . . there may just be no cause for alarm at this point, since time seems to even things out.

Also, the primary concerns of global warming include a melting of the polar ice caps (which would flood many areas and perhaps shut down ocean currents, causing ice ages on certain continents), a drying up of groundwater which many places depend on, and increased tropical storms. It does not take a huge temperature change to cause these things.

Most of that is about people getting worked up over nothing. . . I for one believe that the sun
is primarily responsible for global warming. However, I prefer to let the scientists sort it out. . . hopefully, they will arrive at the correct conclusions - so we can all relax. . .
I thank you for a well thought out (and articulated) argument. . . while I don't agree, I'm not ruling out the possibility of your assertions. I just think that we shouldn't jump to conclusions. . .
