Global warming ice shelf disintegration sea level rise greenhouse effect 0.09m - 0.88m by 2100 loss of land very gradual Greenhouse gases increase in temp caused by earth 'trapping' heat CO2 H2O (g) more gas = warmer anthropogenic climate change main anthropogenic greenhouse gas burning fossil fuels most abundant precipitation

mathematical distance m area m2 speed m s -1 time s ratio no units metric ton = 1000kg mass kg graphs tables always include units sig fig scientific notion label axis i.e. temperature/oC title units in heading use the number of digits certain of plus one more! when x and / use same sig fig in answer to least in question 1 or more but less than 10

Earth surface temperature surface temp - not actually surface= just above 30-year mean surface temp GMST urban heat island every day at set times calculate mean all the values added together then divided by number of results 30 year GMST sum of all mean surface temp / number of locations

uncertainties quote as half a division on recording device i.e 0.5mm experimental uncertainties i.e. series of measurements over 2 minutes show range of values systematic error random uncertainty scattered fairly randomly around some mean value one overall can be estimated by repeating - spread of results indicate random uncertainty PRECISE i.e thermometer scale out slightly systematic uncertainty ACCURATE offset from 'true'
