Examen final Flashcards
(15 cards)
How geographical location influence climatic change effects?
It influences climatic change effects by determining regional weather patterns, vulnerability to sea-level rise, and susceptibility to extreme weather events. Coastal areas face rising sea levels and storms, while arid regions might experience more severe droughts.
What are initial and boundary conditions in climate modelling?
These are the starting values and external factors used in climate models to simulate and predict future climate conditions. Initial conditions include the current state of the atmosphere, oceans, and land, while boundary conditions encompass factors like solar radiation and greenhouse gas concentrations.
What do you mean by climate refugees and how do they differ from traditional refugees?
Individuals forced to leave their homes due to climate-related changes (e.g., sea-level rise, extreme weather). They differ from traditional refugees, who flee due to persecution or conflict, as their displacement is primarily due to environmental factors.
How do computational improvements contribute to enhancing climate models?
Enhanced processing power and advanced algorithms enable more detailed and accurate climate models, allowing for finer resolution, better representation of complex processes, and more reliable predictions.
What is the latest international agreement on climate refugees?
No specific international agreement exists solely for climate refugees. However, discussions continue under frameworks like the Global Compact for Migration to address their unique needs.
What is carbon sink or carbon sequestration? Is it a mitigation or adaptation measure?
The process of capturing and storing atmospheric carbon dioxide, typically through natural processes like forestation or technological means. It is a mitigation measure aimed at reducing greenhouse gas concentrations.
Refugee vs Migrant – are they same?
They are not the same. Refugees are forced to flee due to persecution, conflict, or violence, and have specific protections under international law. Migrants choose to move, often for economic reasons, and do not have the same legal protections.
Adaption vs Mitigation measures
Adaptation involves adjusting to current or expected climate effects to minimize harm (e.g., building flood defenses). Mitigation focuses on reducing the causes of climate change, primarily by lowering greenhouse gas emissions (e.g., renewable energy).
Paris Agreement and Nationally Determined Contributions (NDCs)
The Paris Agreement is an international treaty to combat climate change by limiting global warming. Nationally Determined Contributions (NDCs) are individual country commitments to reduce national emissions and adapt to climate impacts.
What is Green Climate Fund? Is it a part of Paris Agreement?
A financial mechanism under the UNFCCC, aimed at assisting developing countries in adaptation and mitigation practices to counter climate change. It is part of the broader framework of the Paris Agreement.
Aarhus Convention, 1998
An international treaty granting the public rights regarding access to information, public participation, and access to justice in environmental matters to promote environmental democracy.
How green house gas (GHG) emissions happen from agricultural sector?
Emissions occur through activities like livestock digestion (methane), rice paddies (methane), and soil management practices (nitrous oxide).
Can bio-fertilizers better option to reduce GHG emissions?
They can reduce GHG emissions by enhancing soil health and reducing the need for chemical fertilizers, which are major sources of nitrous oxide, a potent greenhouse gas.
what are the impacts of socio-economic factors on population due to climate change
Climate change can exacerbate poverty, displace populations, affect food and water security, and strain infrastructure, leading to increased vulnerability for socio-economically disadvantaged groups.
how can you do water management in places with impacts on water resources due toclimatechange
Strategies include enhancing water use efficiency, investing in infrastructure for water storage and distribution, adopting sustainable agricultural practices, and protecting natural water sources through conservation efforts.
