With all the recent talk about the warmest month, the warmest first 5-months of a calendar year, or the warmest calendar year-to-be (maybe), it's probably a good time to review past NCDC global temperature data in a context that goes beyond the extremely short-term periods of 1 month, 5 months or even a calendar year. As a reminder, it's fair to point out that alarmist-profiteers, such as politicians, global warming scientists, celebrities and reporters, want everyone to focus on short-term movements and the fear of "tipping points," and ignore the more critical, longer-term historical context.

Graphs 1A and 1B reveal that global temperatures have been experiencing a modest flat to cooling trend over recent years. Note that chart 1B actually includes the huge spike in temperatures due to nature's super El Niño - even with that impressive 1998 spike, global temperatures barely increased at a +0.60°C trend per century. Think about it - that's 13 years of essentially very tepid warming (darn close to being flat) despite all the wild, hotter-than-hell predictions of the likes of John Kerry, Obama, Al Gore and James Hansen.
Charts 2A and 2B represent longer-term periods of distinct non-warming and warming periods, per the NCDC data. The great "global-warming" scare is primarily based on the 25 year period ending in 2001 (graph 2B). The temperature increase of a +1.60°C per century trend for that recent period is not even close to being "unprecedented" warming, and is barely different than the warming that is shown in graph 3B. A +1.60°C per century trend is a temperature blip that will absolutely not cause any of the popular catastrophic claims as eagerly publicized by the vast majority of Democrats/leftists/liberals/progressives.
Above graphs 3A and 3B show the NCDC instrumental temperature record dating back to the late 19th and early 20th century. Beginning in 1880, there was an extended cooling period. Graph 3B represents the 33 year warming duration that got its start around 1912. In terms of length and overall warming, the 1912-1944 warming is almost identical to the "Great Warming" of 1977-2001.
Taking the above temperature data and putting it in a longer NCDC temperature record view, the below graph provides the needed context.
When all the warming and cooling periods are combined, there has been overall warming of +0.6°C since 1880, which is entirely normal, considering the realism that world temperatures have been on a natural warming trend since the incredible coldness of the Little Ice Age. Even with the large increase of CO2 levels since 1880, the overall warming is nothing extraordinary or dangerous. And just to be clear, the natural cycles of warming and cooling will keep global temperatures from jumping to the ludicrous heights (as the red dots represent on the above chart) that warming alarmist scientists and eco-activists speculate about.
One last graph and note:
Did the "Great Warming" of 1977 to 2001 actually occur? All the previous charts are based on the NCDC "adjusted" global temperatures not the raw, original thermometer readings. As the above chart reveals, the NCDC scientists have made every conceivable effort to adjust more recent temperatures to be warmer, and to make pre-1945 era warming cooler. Although it's clear that global warming has taken place, there is a very high likelihood that a portion of recent global warming is due to data fabrication.
Finally, have real-world temperatures reached a "tipping point"? The real-world facts don't support that hysterical speculation in the least - it's only in a eco-sexual fantasy dream of an Al Gore, and his ilk, where that climax occurs.
