In 1973, George Kukla and the National Science Foundation forecast global cooling and a new ice age. They cited increased ice and snow in the Arctic as evidence.
In 1981, George Kukla and the National Science Foundation forecast global warming and melting polar ice caps. They cited decreased ice in the Antarctic as evidence.
As the IPCC reported in 1990, Arctic and Antarctic trends go opposite each other. Arctic ice increased from 1973 to 1981, and Antarctic ice decreased during that same period.
Kukla ignored the increase in Arctic ice in his 1981 study, just as climate scientists now ignore the increase in Antarctic ice since 1981.
The one thing constant in climate science is that climate scientists will say whatever is required to obtain funding and they will cherry-pick their data as necessary. What they are doing has absolutely nothing to do with science.
