Can our new cotton varieties handle our changing climate?

摘要

CURRENT projections for climate change indicate that Australia can expect more heatwaves, changes in rainfall distribution and an increase in the intensity of droughts. Natural atmospheric CO_2 concentration during the past 800,000 years ranged between 170 and 300 parts per million (ppm). But atmospheric CO_2 levels have been steadily increasing over the past 200 years from pre-industrial values of about 280 ppm to over 400 ppm in 2016, and with projections for further increases in the future.
