It makes sense if you study it. |
No, it doesn't. The warming of the early part of the century was huge, and there was no man-made effect on it. Then cooling and stabilization. Then, about thirty years of warming. What you posted shows only thirty consistent years of warming. That's insignificant. And, when you compare it with the large NON-man-made warming, it makes it a pointless blip of data.

There has always been variation in the planet's climate because it is a dynamic system. The many phenomena that influnce global temps have various interactions, not easy to understand in just a few sentences. One example: clouds reflect solar energy from space (albedo) creating a net cooling; they also reflect back heat from the earth's surface, which is why overcast nights are warmer than clear nights. This seemingly simple occurrence does not act alone; other things will affect the net gain or loss of heat -- GHG concentrations, aerosols, relative temp, etc.
For a good primer, see NOAA's Q&A (Global Warming Frequently Asked Questions) or see other links in earlier posts.

I saw, I read. I've read others. Nothing, not a single thing, points to any EVIDENCE of man-made effects on the very short term warming that may (if the data were accurate) be occuring. But, even the data has huge question marks around its accuracy. Not to mention that significant points changed with the change of the USSR. A little unbiased research points to short term potential minor warming, nothing outside of the normal band of global temperatures.
