When speaking about the difference between weather and climate, which of the following would best describe "Climate"?

Cold
Windy
Tropical
Cloudy

That's correct! Way to go

The difference between weather and climate is the factor of time. Weather refer to short-term atmospheric conditions, while climate refers to the average weather conditions over time. https://www.esa.int/Applications/Observing_the_Earth/Space_for_our_climate/Weather_vs_climate_What_s_the_difference#:~:text=The%20difference%20between%20weather%20and,a%20long%20period%20of%20time.

By what year is it predicted that 1/3 of the world's population may be living in a climate like the Sahara Desert?

2100
2080
2070
2060

That's correct! Way to go

Scientists at PNAS have conducted a study and concluded that in 50 years, the geographic temperature niche of Earth will shift and, due to lack of migration with the temperature shift, cause nearly one third of the population to live in Sahara Desert-like conditions. https://www.pnas.org/doi/10.1073/pnas.1910114117

What is a Polar Vortex?

A large area of low pressure and cold air over Earth's north and south poles surrounded by the jet stream.
It is what controls the frequency of and brilliance of the northern lights in Alaska
It is the annual congregation of polar bears in an Alaskan village which dedicates a whale carcass to them for feeding.
It is the natural balancing of warm and cold temperatures in Alaska which regulates the rate at which seawater will freeze in the winter.

That's correct! Way to go

The polar vortex always exists but weakens in the summer and strengthens in the winter. When the jet stream weakens it becomes wavier, allowing the cold air to dip southward in places while warmer air pushes northward elsewhere. https://www.weather.gov/safety/cold-polar-vortex

Why is it unlikely that airplanes will convert from fossil fuels to sustainable jet fuels in the immediate future?

A commercial plane flew across the Atlantic Ocean for the first time using what kind of alternative sustainable fuel?

Sewage
Waste fats and plant sugars
Sand and ammonia
Chlorine, nitrogen, and oxygen

That's correct! Way to go

The plane made the trip on a SAF, aka Sustainable Alternative Fuel, made out of waste fats and plant sugars. Find our article covering it on our What's New? page!

What material has toilet paper begun to be made of as a more biodegradable and sustainable option?

Kelp
Seaweed
Bamboo
Nylon

That's correct! Way to go

Bamboo is right! Check out our article about it under The Daily Assignment :)

How many trees around the world are cut down EACH DAY to produce toilet paper?

95,000
18,000
45,000
27,000

That's correct! Way to go

Every day approximately 270,000 trees are flushed or find their way to landfills. About 10% of that (27,000 trees) are from toilet paper. https://bigthink.com/health/toilet-paper-is-a-giant-waste-of-resources/

How many rolls of toilet paper do individual Americans use each year?

40
86
141
187

That's correct! Way to go

Individuals in the U.S. use approximately 141 rolls of toilet paper per year. Despite only accounting for about 4% of the world population, Americans use 20% of the world's toilet paper. https://earth911.com/living-well-being/rethink-toilet-paper-use/#:~:text=Each%20person%20in%20the%20U.S.,would%20equal%20about%20634%20miles.
