"Caltech’s 1974 commencement address."
That was 78 years after Arrhenius published his paper, and nary a mention that it is "the greatest hoax". How very weird.
"If you’ve made up your mind to test a theory, or you want to explain some idea, you should always decide to publish it whichever way it comes out."
We are testing it, and, here is one of the most recent publications, entitled "Observations from inside the test tube"....
Global Temperatures
With the contribution of eight consecutive high monthly temperature records set from January to August, and the remainder of the months ranking among their five warmest, 2016 became the warmest year in NOAA's 137-year series. Remarkably, this is the third consecutive year a new global annual temperature record has been set. The average global temperature across land and ocean surface areas for 2016 was 0.94°C (1.69°F) above the 20th century average of 13.9°C (57.0°F), surpassing the previous record warmth of 2015 by 0.04°C (0.07°F). The global temperatures in 2016 were majorly influenced by strong El Niño conditions that prevailed at the beginning of the year.
This marks the fifth time in the 21st century a new record high annual temperature has been set (along with 2005, 2010, 2014, and 2015) and also marks the 40th consecutive year (since 1977) that the annual temperature has been above the 20th century average. To date, all 16 years of the 21stcentury rank among the seventeen warmest on record (1998 is currently the eighth warmest.) The five warmest years have all occurred since 2010.
Overall, the global annual temperature has increased at an average rate of 0.07°C (0.13°F) per decade since 1880 and at an average rate of 0.17°C (0.31°F) per decade since 1970.
