Science and Engineering is based on measurement and interpretation of those measurements. If you do not understand the latest global measurements, you cannot understand Climate Change.
[aka Lord Kelvin]
When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind: it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science.

Fifteen years go I put up a page on Global Warming. I copied into Excel all the monthly measurements from January 1880 to the present thinking next year I only had to add the last 12 months. I was wrong. The updated official government release of all the temperatures back to 1880 showed lower temperatures. So I re-entered all the new data. The next year the same thing happened. The temperature in 1880s kept dropping. Obviously someone was tampering with the data so I no longerer maintained a page on "Global Warming". In all the measurements I have collected, I have never gone back and changed a measurement. But I have had to try to explain what happend when a measurement did not fit the pattern. In Government, politics pre-empts accurate measurment which is real science.
On the other hand, there has been little if any modification of Global Temperature Measurements from Global Temperature Sattellites. The following data shows that data. Relative temperature in degrees Centigrade vs. time is shown. Raw data in green. Smoothed data in red. Essentially no change in the last 22 years:
[ Low Pass Smothing Filter = (.2, .4, .6, .8, 1, 1, 1, 1, 1, 1, 1, 1, .8, .6, .4, .2)/12. ]
This is my opinion.
This first video is a bit technical so you need to be able to compare patterns. The current pattern has often preceded a significant drop in Global Temperature.
