global warming and its impact Flashcards
is the long-term rise in Earth’s average surface temperature caused by
the accumulation of greenhouse gases in the atmosphere.
Global warming
is a natural
phenomenon in which certain gases in Earth’s
atmosphere trap heat from the sun, keeping
the planet warm enough to support life
greenhouse effect
Human reliance on fossil fuels like coal, oil, and natural
gas for electricity, transportation, and industry is a major contributor to global
warming.
Burning of Fossil Fuels
Large-scale cutting of forests for agricultural expansion, urban
development, or timber reduces the number of trees available to absorb carbon
dioxide from the air.
Deforestation
The agricultural sector contributes to global warming in multiple ways.
Agriculture
Improper handling of waste, especially organic materials like
food and plant matter, results in significant methane emissions when the waste
decomposes in landfills.
Waste Management
is a key driver of carbon dioxide
emissions due to the widespread use of vehicles powered by gasoline and diesel.
Transportation
- Rapid urban development increases energy demand for construction,
transportation, and infrastructure.
Urbanization

Melting glaciers and thermal expansion of saltwater are
causing sea levels to increase, endangering coastal towns.
Rising Sea Levels:
Hurricanes, droughts, and floods are becoming
more frequent and intense, disrupting people’s lives and businesses.
Extreme Weather Events:
Many species are on the verge of extinction as a result of
habitat loss and shifting weather patterns.
Biodiversity loss:
Heatwaves, vector-borne illnesses, and pollution all pose _________
throughout the world.
health risks
a significant consequence of global
warming, contributing to rising sea levels and altering ecosystems worldwide.
Melting of Ice Caps and Glaciers:
effects of global warming
-rising sea levels
-extreme weather events
-biodiversity loss
-health risk
-melting of ice caps and glaciers
impacts of global warming in human life
-heat related illnesses and mortality
-spread of infectious diseases
-food and water scarcity
-economic impact
-displacement and migration
-energy demand and energy supply
The treaty, which mandated that nations cease producing chemicals like
chlorofluorocarbons (CFCs) that harm the ozone layer, was finally ratified by every
nation on the planet.
Montreal Protocol, 1987
The parties also decided to cut back on the production of hydrofluorocarbons (HFCs),
which are potent greenhouse gases that fuel climate change.
Kigali Amendment (2016)
The historic agreement, which was ratified by 197 nations, including the US, was the
first international agreement to specifically address climate change.
UN Framework Convention on Climate Change (UNFCCC), 1992
It was the first legally binding climate accord, having been adopted in 1997 and
coming into effect in 2005.
Kyoto Protocol, 2005
The ___________________, the most important global climate pact to date, mandates that all
nations make pledges to reduce their emissions.
Paris agreement
One of Southeast Asia’s most ambitious goals is the Philippines’ pledge to cut
emissions by __% by 2030.
75
The government’s only policy-making organization tasked with organizing,
overseeing, and assessing the Philippines’ climate change-related initiatives and action plans.
Climate Change Commission (CCC)
Encouraging the convergence of ecosystem management and restoration, disaster risk
reduction, and climate change adaptation as a successful strategy to increase community
resilience, and implementing this strategy throughout all of our activities.
CARE Philippines
The Act recognizes the necessity for suitable adaptation and the Philippines’
susceptibility to climate change.
Republic Act 9729 (Climate Change Act of 2009)
The People’s Survival Fund is a long-term funding source created by ____________
