also called climate engineering, in the development of technology that directly alters the Earth's atmopshere to combat climate change

How has science been working on preventing future consequnces of climate change

an extremely clean method of generating electricuty electricity non polluiting more expensive than traditional ways of convering energy

When you multiply just one footprint across and entire society, there are real consequences. Why is this true?

bc modern society requires more energy per person than at any time in the history of our species

What is the problem with the unknowns to help address climate

carbon footprint

Different sources of energy for electricity and transporation contibute to what?

climate change differently in terms of carbon emissions

What are examples of nonrenewable energy sources, aka fossil fuels?

coal oil natural gas

What is nuclear energy?

comes from splitting the tight knit nucleus of an atom, usually using materials like uraniam

fossil fuels in cars, planes, and buses versus carpool, public transit and hybrid or electric

What are the challenges when attempting to implement technology to address climate change?

funding public acceptance the unknowns

The process of nuclear enegry is used to do what?

gather nuclear enegry produces radioactive byproducts that are dangerous and need to be disposed of somehow

How does the removal of carbon dioxide from the atmosphere combat climate change?

genetically engeneering trees or other plants to increase their consumption of carbon dioxide large quantities of carbon dioxide are removed from the atmosphere

How has science been working on addressing current consequnces of climate change

it can make it challenging and even impossible in some places

Nuclear power is considered cleaner than fossil fuels, but?

it is not without risk

What does CDR technology, carbon dioxide removal tech, aim to do?

lower the current level of carbon dioxide through - reforestation - creating carbon sinks in soil and ocean

What is genetic engineering?

modifying plants and animals

What is not considred to be a clean form of alternative energy?

nuclear power

What is the deal with beef and carbon emissions?

raising callte requires more land than other livestock. cows are some of the largest biotic contributors, in part because they produce methane and other greenhosue gases

reduce your overall footprint

What does SRM technology, solar radiaiton management technology, aim to do?

reflect solar energy before it reaches the Earth - prevent it from getting trapped by greenhouse gases and warming the planet further
