  • weeds - in a time of climate;
  • warming, effect on plant function and carbon dioxide rise - principal greenhouse gas, direct influence on plant biology;
  • climate change and carbon dioxide levels - not distinguishing between plant species, anthropogenically beneficial;
  • understanding implications - nature of individual versus group change;
  • agriculture, its simplest arrangement - as a managed plant community;
  • crops and weeds - responding differently to environmental change;
  • weed populations in agricultural systems - diversity, and different species;
  • native systems, unmanaged plant communities - invasive plant species (IPS), a threat to community function;
  • three broad areas of uncertainty - in relation to weeds and climate change;
  • CO2 emissions - exceeding IPCC scenarios
