how many subsystems make up the earth
4
geosphere
atmosphere
hydrosphere
biosphere
Alexander The Great (where was he from what'd he do)
Greek King from Macedonia; conquered Egypt and Persia then travelled to India. The Romans ruled much of the land he conquered bc idk they can
Whether climate trends played a role in the rise and fall of the Greek and Roman empires
what does Anthropocene mean
humans and how the environment plays a role in society (making major impact
Whats a forcing
external forces interfering with subsystem
Holocene Turnover define it
abrupt change in atmospheric and oceanic conditions
When did people start burning lots of coal and other stuff - start making major environmental impacts (give an era in history)
Industrial revolution
Positive feedback vs negative feedback (double if you can name the vocab word for when it goes too far)
Positive - both forcings have same effect (keep going beyond till they reach a TIPPING POINT)
negative - both forcings have opposite effects (cancel out)
Pleistocene define it
a period where humans evolved across the globe, adapting to their environment and developed new tools and technologies. Glaciers grew and receded
what is the Advisory Group on Greenhouse Gasses (AGGG)'s goal
to ensure the coordination of the observational network that provides long-term “climate-quality” data on trends and spatial distributions of long-lived (LL) GHGs and related tracers.
What is a proxy and what are the 3 main proxies
something in nature that indicates previous conditions
ice, trees, soil
Whats the LGM (Last glacial maximum) and when it was
population estimate 1780, 1930, today
1780 - human population was less than 1 billion people, 1930 - around 2 billion people, now, more than 8 billion in even less time
what are the milankovitch cycles and what are the durations
change the shape/orbit of the earth slightly impacting how the sun's energy hits earth
happens in intervals of 100,000 : 26,000 : 41,000
Akkadian Empire where was it, when was it, what'd they do
egypt located on the Nile Delta
Fall of the Old Kingdom(c.2700-2200 BCE) linked to drought
Developed form of writing allowed for irrigation practice to be recorded
what's the Triple planetary Crisis (pretty easy even if you don't know just guess)
climate change, air pollution, biodiversity loss
