" Current atmospheric concentrations of CO2 and CH4, and their associated positive radiative forcing, far exceed those determined from ice core measurements spanning the last 650,000 years."
" Fossil fuel use, agriculture and land use have been the dominant cause of increase in greenhouse gases over the last 250 years."
"Natural processes of CO2 uptake by the oceans and terrestrial biosphere remove about 50 to 60% of anthropogenic emissions (i.e., fossil CO2 emissions and land use change flux). Uptake by the oceans and the terrestrial biosphere are similar in magnitude over recent decades but that by terrestrial biosphere is more variable"
"The rate of sea level change over recent decades has not been geographically uniform."
