Not exact matches

Using different calibration and filtering processes, the two researchers succeeded in combining a wide variety of available data from temperature measurements and climate archives in such a way that they were able to compare the reconstructed sea surface temperature variations at different locations around the globe on different time scales over a period of 7,000 years.

Using a scanning tunneling microscope, the researchers took pictures of the individual moleculesknown as phenylene ethynylene oligomerson a surface coated with a different chemical over time periods of up to 26 hours.

Now, since they use different methods and measure different things in different ways, its mere childs play to find time periods when they «disagree» I think Christy just presented a nice little recap of all the differences over at the surface temp conference.

Skill in describing the statistical distribution of surface variables is very different from skill in predicting specific values of those variables over a limited period of time (like a decade).

See, the first thing to do is do determine what the temperature trend during the recent thermometer period (1850 — 2011) actually is, and what patterns or trends represent «data» in those trends (what the earth's temperature / climate really was during this period), and what represents random «noise» (day - to - day, year - to - random changes in the «weather» that do NOT represent «climate change»), and what represents experimental error in the plots (UHI increases in the temperatures, thermometer loss and loss of USSR data, «metadata» «M» (minus) records getting skipped that inflate winter temperatures, differences in sea records from different measuring techniques, sea records vice land records, extrapolated land records over hundreds of km, surface temperature errors from lousy stations and lousy maintenance of surface records and stations, false and malicious time - of - observation bias changes in the information.)
