few variables used to define weather correct answers temperature, precipitation, humidity
state of atmosphere parameters correct answers temperature, precipitation, humidity
define WEATHER correct answers time-averaged variables of temp, precipitation, humidity over
a SHORT period of time (days...months)
the state of the atmosphere at a particular time (over a short period of time)
fluctuates greatly and difficult to predict
'what we get'
can be defined spatially (same with climate)
define CLIMATE correct answers time-averaged variables of temp, precipitation, humidity over
a LONG period of time(years)
= long-term pattern of weather
more predictable than weather
'what we expect'
can be defined spatially (same with weather)
, measurements of climate change incl... correct answers temperature, humidity, precipitation,
wind etc.
def Global Climate Change correct answers statistically significant changes in Earth Climate
occurring over a time scale of centuries
main variable in defining Global Climate correct answers =surface temp
mean (avg over entire Earth) surface temperature (land and ocean) averaged over a 1-5 years +
define Current Warming correct answers Mean Global Surface Temperature (GMST) increasing
~1 degree over last century
^ GMST = the surface temp of the Earth averaged over 1-5 years
Did we have global warming in the past? correct answers YES, we had both warming + cooling
periods (Jean-Robert Petit study)
Temperature changes ~10 degrees over last 400 000 years
main variable defining ALL climate correct answers Temperature
looking at large-scales (geological) of climate change, is there global warming? correct answers
NO -> bc it shows a pattern of continual change with major ice ages occurring every 100 000
years
methods to measure past climate/global temperatures correct answers Proxies - climate imprints
(indirect evidence) during past time periods used to determine the climate at that time period
