While science is not yet capable of providing precise predictions, there is wide agreement in the scientific community on some climate change trends. The IPCC projects that warming will be greater at the equator and the poles than at the mid-latitudes.b In very general terms, this may translate into more favourable agricultural conditions for temperate regions (e.g. warmer, longer growing season), but less favourable conditions (e.g. heat stress) in the already hot tropics. Global water availability is likely to remain constant.
