What are the four categories of responses to climate change?
Adaptation
mitigation
solar radiation management
CO2 removal
What is mitigation?
policies that avoid climate change
What is solar radiation management?
active manipulation of climate system in order to reduce energy in
What is CO2 removal?
active manipulation of carbon cycle in order to hasten removal of CO2 from atmosphere
What are the factors in climate change mitigation?
controlling world’s population
reduce world’s consumption of goods and services
What is carbon free/safe?
reducing carbon intensity is code for switching from fossil fuels to energy sources that don’t release greenhouse gases
What is renewable energy?
energy sources that aren’t depleted when utilized
What are examples of renewable energy?
hydroelectric
solar
wind
geothermal
biomass
What are 2 different ways to generate energy from sunlight?
solar photovoltaic
solar thermal methods
What are problems with large scale adoption of solar and wind energy?
intermittency
land requirement
stresses food supply
What is carbon sequestration?
fossil fuels are burned in a way that CO2 generated is not vented into the atmosphere
What is dispatchable power?
energy sources that are available any time and can be dispatched at request of electric grid operators
What is direct air capture?
removes CO2 from atmosphere
What is overshoot?
temperature temporarily exceeds dangerous threshold for a few decades before declining back below threshold
