Good science penguins don’t cherry pick the data to get the answer they want. Let me demonstrate.
If I run the trend from 1/98 through 12/08 I can get a negative trend.
Move the start back a year to 1/97 the trend goes positive again.
Move the original stop back a year the trend goes positive again.
You can do this at multiple points in history and make the trend line look like a stair. However the long term trend is up.
Look at the high peaks and the low peaks. Both are getting consistently higher over time. That trend has not stopped just because 1998 was an exceptionally hot year. That trend, according to the UAH data, is 0.19 degrees C per decade over the period of time they have been collecting data.
