Large precipitation increases could counteract the declines that these all - but -
certain future temperature increases will cause.

Current climate change models indicate
temperatures will
increase as long as humans continue to emit greenhouse gases into the atmosphere, but the projections of
future precipitation are far less
certain.
To date, while various effects and feedbacks constrain the certainty placed on recent and projected climate change (EG, albedo change, the response of water vapour, various
future emissions scenarios etc), it is virtually
certain that CO2
increases from human industry have reversed and will continue to reverse the downward trend in global
temperatures that should be expected in the current phase of the Milankovitch cycle.
The IPCC has already concluded that it is «virtually
certain that human influence has warmed the global climate system» and that it is «extremely likely that more than half of the observed
increase in global average surface
temperature from 1951 to 2010» is anthropogenic.1 Its new report outlines the
future threats of further global warming:
increased scarcity of food and fresh water; extreme weather events; rise in sea level; loss of biodiversity; areas becoming uninhabitable; and mass human migration, conflict and violence.
