DESCRIPTION:Prof Rob Mackenzie\, University of Birmingham\, joins us for 
 a Department of Earth and Environmental Sciences seminar. Abstract below
 . \n\nThe land carbon sink is calculated to be the most important carbon
  cycle feedback to 21st century climate change\, yet forecasts are highl
 y uncertain and Earth-system models of the process contain ‘known unknow
 ns’. Nutritional constraints and environmental stress may soon limit the
  land sink\, especially in mature forests\, which make up a dominant par
 t of the sink. This would mean that current climate projections are over
 ly optimistic because scenarios\, such as those used to inform the Paris
 -Katowice Agreement\, rely on a continuing strong sink. The Birmingham I
 nstitute of Forest Research (BIFoR) FACE is one of the three largest glo
 bal change experiments in the world. BIFoR FACE is set in UK broadleaf f
 orest dominated by 160-year-old and 25 m tall oak trees interspersed wit
 h sycamore\, hazel\, hawthorn\, and holly. CO2-enrichment\, scheduled to
  run until 2026\, commenced in spring 2017 and has performed to very hig
 h engineering standards. The whole canopy volume of three replicate 30m-
 diameter (0.07 ha) plots is immersed in air containing 150 ppm CO2 above
  ambient. The whole forest system responds promptly. So far\, we find sp
 ecies-dependent increased carbon assimilation\, increased fine root prod
 uction\, and responses in water and nutrient cycling. Whether these sign
 als will persist is the $50M question.
