Science And Technology Geoengineering || All Correct.
Who is responsible for the Earth's rapidly warming temperatures? correct answers human activity
What are some consequences of global warming? correct answers rising sea levels, extreme
weather phenomena, and mass extinctions
True or False? It is clear that we cannot stop climate change in time to prevent all consequences.
correct answers True
mitigate correct answers make less severe, serious, or painful
At best what can we do about climate change? correct answers slow it down
What type of engineering focuses on removing carbon dioxide from the atmosphere? correct
answers geoengineering
What is geoengineering? correct answers Geoengineering involves large scale efforts to change
the Earth in an attempt to decouple the effect of carbon emissions on our climate. In other words,
it tries to make carbon emissions not affect the climate as drastically.
What does CDR stand for? correct answers Carbon Dioxide Removal, also known as negative
emissions
What does CDR aim for? correct answers Aims to address the primary driver of climate change
by removing carbon dioxide (CO2) from the atmosphere and ensuring its long-term storage. If
deployed at a large-scale, CDR could slow the rate of global warming and help prevent ocean
acidification.
What does UNFCCC stand for? correct answers United Nations Framework Convention on
Climate Change
What does IPCC stand for? correct answers Intergovernmental Panel on Climate Change
According to IPCC, in order for all pathways to keep global warming under 1.5°C, CDR has to
remove how many Gigatonnes of accumulated CO2? correct answers between 100 - 1000 by
2100
What things are needed for the large scale CDR and how can governance help? correct answers
Extensive amounts of land, energy or water and might compete with food production or other
activities. Some technologies could result in negative effects for biodiversity, air, ground water
and soil quality. On the other hand, other approaches, such as soil sequestration of carbon could
improve crop productivity and biodiversity. Different CDR methods could affect communities
unequally, creating liability and compensation issues. Governance could help address these
issues and strengthen accountability.
, What risk comes when focusing on large scale CDR? correct answers creates a moral hazard as it
might delay efforts to reduce emissions
What are the different kind of impacts that international governance needs to address? correct
answers Cross-border environmental, social and economic impacts, as well as issues around
responsibility, liability, monitoring and accounting, as well as finance.
What does CBD stand for? correct answers Convention on Biological Diversity
What does UNEA stand for? correct answers United Nations Environment Assembly
What are Afforestation and forest ecosystem restoration correct answers Planting and restoration
of forests that result in long-term storage of carbon.
What is the act of Enhancing soil carbon content? correct answers Land management changes
that increase soil carbon concentration and biochar.
What is Bio-energy with carbon capture and storage? correct answers Burning biomass for
energy generation and capturing and long-term storage of the resulting CO2.
What is Enhanced weathering and ocean alkalinity? correct answers Enhancing natural
weathering of rocks by extracting, grinding and dispersing carbon-binding minerals on land, or
adding alkaline minerals to the ocean to enhance carbon uptake.
What is Direct air capture and storage? correct answers Capturing CO2 directly from ambient air
by a chemical engineering process, followed by long-term storage or use.
What is Ocean fertilization? correct answers Fertilizing oceans to accelerate phytoplankton
growth, which absorbs CO2 then dies transporting carbon from the atmosphere to seabed
What is Building with biomass? correct answers Using carbon embedded in biomass (such as
timber) in construction.
What does MRV stand for? correct answers monitoring, reporting and verification
Carbon Sequestration correct answers Carbon Dioxide is incredibly harmful to the planet due to
its property to trap heat in the atmosphere. Attempts to solve this by capturing and storing
carbon. This process occurs naturally in plants (#TeamTrees), soils and the ocean, with large
areas of this captured CO2 being known as a Carbon Sink (basically underground). By storing
this carbon, it prevents it from entering the atmosphere and trapping heat.
Land Use Management correct answers Though generally, this means managing the land and the
resources on it in whichever way individuals and governments determine to be necessary, in the
context of carbon dioxide removal, land use management can include reforestation (restoring
forests), afforestation (converting non-forested land to forest) and optimizing forestry and
agricultural practice.
