SEARCH BLOG: CLIMATE CHANGE
With all of the uproar caused by Steven McIntyre's analysis of NASA/NOAA's temperature records and the revelation that not only don't climate models fit observations, but the data used in those models may well be improperly manipulated by NASA/NOAA itself... it may have occurred to some that any conclusions drawn from the data and the models may be unreliable ;-).
Sure, that's an understatement... if you hadn't already guessed.There certainly is evidence that the decade of the 90s and this decade are warmer than the decades of the 60s and 70s which were cooler than the decades of the 30s and 40s which were warmer than the decades of the teens and 20s.
Is there a pattern developing here?But when you look beyond that there appears to be a north-south pattern to the changes as well. Quite honestly, given the sad shape of weather monitoring stations and the re-siting that seems to occur so often, it seems that the records are best seen as approximations of the temperature conditions around the world... which is evidenced by NASA/NOAA's continual attempts to "correct" the actual records.
The north-south pattern was evidenced in the first climatalarmist episode in the 70s when the northern hemisphere was cited as evidence of an impending ice age. Watch the video on the sidebar under the heading: MINDS CHANGE - TACTICS DON'T. Then, the southern hemisphere was just fine.So, let's review the points here:
The current climatalarmist episode cites the northern hemisphere warming, including northern polar ice reduction, as evidence of the impending steam bath age(?). The problem now is that the southern hemisphere has shown signs of cooling with snow in Brazil and thickening ice in Antarctica.
- Weather monitoring stations have not been properly maintained in the majority of sites surveyed [see link above] and in most countries around the world the sites have serious recordkeeping problems.
- Temperature histories are being revised by NASA/NOAA in ways that appear to be unjustified in many instances
- U.S. temperature history of record high temperatures [more of which were supposed to result from global warming] shows an oscillating pattern more than the upward trendline of "average temperatures" calculated from these questionable stations and manipulated data [although the revised approach to global warming is that the warming is from fewer cold days rather than more record hot days].
- The previous climatalarmist projection was for an ice age based on northern hemisphere observations not supported by southern hemisphere observations
- The present climatalarmist projection is for accelerating global warming based on northern hemisphere observations not supported by southern hemisphere observations.
