Soil respiration

The flux of carbon (mostly CO2) from the soil surface is about an order of magnitude larger than anthropogenic CO2 emissions, and is the second-largest flux in the terrestrial carbon cycle. This graph shows records in the Web of Science database about soil respiration, arbitrarily and approximately separated into "interesting" (field studies examining temperature response and/or fluxes over time) and "not interesting" (modeling, remote sensing, incubations, microbial response).

Snakes and Ladders

It turns out that Snakes and Ladders can be won in seven moves, but the probability of this is only 0.2%. The most common number of moves to win is 20 (3.6%), and 1.5% of the time you'll need more than 100 moves.
