My understanding is that agility scores are based on speed and number of mistakes. On the latter he does pretty well, on the former, not so much. On crowd pleasing he gets the top score.

Volume II of the Fourth National Climate Assessment (NCA4) has just recently been released. This is critical reading for anyone concerned about the future of our planet and the future of humanity. Here is a link to Chapter 1: Overview. Volume I, Climate Science Special Report (CSSR) was published in 2017 and provides the scientific basis for the observed and projected risks and impacts of climate change now and in the coming years as discussed in Volume II. A summary of the CSSR is provided in Chapter 2 of Volume II.
Global climate is changing rapidly compared to the pace of natural variations in climate that have occurred throughout Earth’s history. Global average temperature has increased by about 1.8°F from 1901 to 2016, and observational evidence does not support any credible natural explanations for this amount of warming; instead, the evidence consistently points to human activities, especially emissions of greenhouse or heat-trapping gases, as the dominant cause.
This video was produced by a group affiliated with the University of Colorado called Interactive Geology Project. It is a very well done animated rendition of the geologic history of Colorado. It was originally presented at the 2015 convention of the American Association of Petroleum Geologists in Denver, so it has a little extra emphasis on oil and gas geology (at least it seems that way to me) but it should be of interest to non-geologists in understanding how Colorado geology and physiography developed over the earth's history. There are a number of other interesting geology-related videos on their site.
Wanted to post this ASAP before I forgot. No need to explain why.

Excellent story in the NY Times about the world-wide collapse of insect populations, why it is occurring (hint: climate change, pesticides, loss of habitat), and why it is of critical importance to human populations.
