1. Since the pre-industrial era, Canada has been one of the largest emitters of greenhouse gases (GHG) in the world. What rank is he at?
A) 26e rank
B) 4e rank
C.10e rank
D.17e rank
Answer: C
At the end of 2022, Canada was ranked 10e rank of countries having emitted the most GHGs since 1750, behind South Korea and just ahead of Mexico, according to the data site Our World in Data. China ranks first ahead of the United States and India.
2. Oceans cover 70% of our planet’s surface and play a key role in climate regulation. They have absorbed a significant part of the heat caused by rising greenhouse gas emissions. How much heat did they absorb?
A) 90%
B) 50%
C) 70%
D) 60%
Respond to
It is estimated that the oceans have absorbed 90% of the heat emitted since the pre-industrial era. The good news is that without the oceans, the rise in surface temperatures would be even greater. The bad news is that by absorbing so much heat, the oceans are also warming, worsening the effects of climate change.
3. You are making a return flight from Montreal to Paris (11,800 km) and you want to offset CO emissions2 (2.5 tonnes) by eating only local products. How long will it take you to offset these emissions?
A) 3 years and 5 months
B) 12 years and 9 months
C) 2 years and 7 months
D) 8 years and 6 months
Answer: D
It takes on average 8 years and 6 months to offset 2.5 tonnes of GHGs by eating local products. The figures are calculated by a tool put online by the daily newspaper The worldwhich is based among other things on the 6e assessment report of the Intergovernmental Panel on Climate Change (IPCC), published in 2022.
4. Since the entry into force of the Endangered Species Act, in 2002, the Government of Canada adopted an emergency decree only twice to protect an endangered species on private lands, both times in Quebec. What species is it?
A) The beluga
B) The Western Chorus Frog
C) Caribou
D) The little bittern
Answer: B
Ottawa adopted a first emergency decree in 2016 to protect the habitat of the chorus frog in La Prairie, then threatened by a residential subdivision project. A second decree was adopted in 2021 to protect the species in Longueuil, threatened by the project to extend Béliveau Boulevard, in the borough of Saint-Hubert.
5. If the CO2 only constitutes 0.04% of our atmosphere, how can it have such a significant effect on our planet’s climate?
A) It amplifies the sun’s radiation on Earth.
B) It interacts with nitrogen to cause warming.
C) It absorbs infrared radiation emitted by the Earth.
D) It’s a mystery, science has no answer.
Answer: C
It is true that CO2 only constitutes a tiny part of our atmosphere, with, among others, nitrogen (78%), oxygen (21%), argon (1%) and carbon dioxide (CO2) at 0.04%. But if the CO2 is a greenhouse gas, this is because it has the property of absorbing the heat released by our planet, which increases the heat on Earth. A greater quantity of CO2 means greater warming.
6. We produce more and more electronic waste, which often ends up in landfills rather than being recycled. How much electronic waste did the world produce in 2022?
A) 62 million tonnes
B) 107 million tonnes
C) 512 million tonnes
D) 37 million tonnes
Respond to
According to the Global E-waste Monitor 2024 report produced by the United Nations Institute for Training and Research and the International Telecommunications Union, the world produced 62 million tonnes of electronic waste in 2022, the equivalent of 7.8 kg per human being. It is estimated that only 22% of this waste was properly recycled.
7. What percentage of our water consumption is used to operate toilets in a Quebec residence?
A) 10%
B) 30%
C) 15%
D) 40%
Answer: B
According to official data, 30% of our water consumption is used for using toilets. An equal proportion goes to baths and showers, 20% is used for laundry and cleaning and only 10% of the water consumed is drunk or used for food.
