That shows an overall trend downward in temperatures since the Minoan warming peak about 3400 yrs ago. Seems to me some global warming would be a good thing.

Re: Hottest Year on Record? What Record? I'm not sure how much you can infer about global temperatures from the Greenland Ice core record. That is only one location on the earth and we don't know how that relates to the rest of the planet.

More from Dr. Easter brook, the author of the graph you posted: gsa.confex.com These late Pleistocene, global, climate changes have implications for understanding present–day global warming. Climatic modelers have predicted that global temperatures will soar in the next several decades as a result of increased atmospheric CO2. However, evidence from glaciers and the oceans suggest that these predictions may be premature. Advance and retreat of glaciers in the Pacific NW and elsewhere show three distinct oscillations, each having a period of ~25–30 years. Glaciers advanced from about 1890 until the early 1920s (cool cycle), retreated rapidly from ~1930 to ~1950-55 (warm cycle), readvanced from ~1955 to ~1980 (cool cycle), then retreated rapidly from ~1980 to the present (warm cycle). Comparable, cyclical, oscillation patterns occurred in the North Pacific (PDO), the North Atlantic (NAO), Europe, and Greenland. Global temperature curves show a cool reversal from ~1950 to 1980) at a time when large amounts of CO2 were introduced into the atmosphere, inferring that global temperatures then were not driven by atmospheric CO2. During this cool cycle, solar irradiance curves almost exactly match the global temperature curve. Satellite data indicate intensifying solar radiation over the past 24 years, coinciding with the present 25–year warm cycle and suggesting a solar cause for the warming. If the cycles continue as in the past, the current warm cycle should end in the next few years, and global warming should abate, rather than increase, in the next 25–30 years, followed by renewed global warming in the following 25–30 years.
