Module 1-4 Flashcards
refers to a large-scale change in the climate system that takes place over a few decades or less, persists (or is anticipated to persist) for at least a few decades and causes substantial disruptions in human and natural systems. It is a
change in climate that happens much faster than it normally would.
Abrupt climate change
the process of adjustment to actual or expected climate and its effects, in order
to moderate harm or exploit beneficial opportunities; human intervention may
facilitate adjustment to expected climate and its effects or making changes to live
with the impacts of climate change.
Adaptation
the primary greenhouse gas and driver of climate change.
Carbon dioxide (CO2)
methods or processes that remove CO2 from the atmosphere by either increasing biological sinks of CO2 or using chemical processes to directly bind CO2.
Carbon dioxide removal (CDR)
when anthropogenic CO2 emissions are balanced globally by anthropogenic carbon dioxide removals over a specified period or net-zero carbon dioxide emission or no net carbon dioxide is added into the air.
Carbon neutral
the average of weather patterns over a longer period of time (usually 30 or more years).
Climate
the long-term changes in the Earth’s climate, or a region on Earth, and includes more than just the average surface temperature. For example,
variations in the amount of rainfall, sea levels, and sea ice can all be consequences.
Climate change
the lead policy making body of the Philippine Government tasked to coordinate, monitor and evaluate government programs and ensure the mainstreaming of the climate change development plans at all levels towards climate resilient and climate-smart Philippines.
Climate Change Commission
a yearly international climate conference where nations assess progress and determine next steps for action through the UNFCCC treaty.
They work on global agreement to reduce greenhouse gas emissions.
Conference of the Parties (COP)
are greenhouse gases released into the air that are produced by numerous activities, including burning fossil fuels, industrial agriculture, and melting permafrost, to name a few. These gases cause heat to be trapped in the atmosphere, slowly increasing the Earth’s temperature over time.
Emissions
sources of non-renewable energy, formed from the remains of living organisms that were buried millions of years ago. Like coal and oil to produce energy, where the majority of greenhouse gases originate.
Fossil Fuels
an increase in the Earth’s average surface temperature from human-
made greenhouse gas emissions.
Global warming
a chemical compound found in the Earth’s atmosphere, such as carbon dioxide, methane, water vapor, and other human-made gases that allow much of the solar radiation to enter the atmosphere, traps and warms the earth surface.
The more heat is trapped, and the warmer it will become.
Greenhouse Gas
Outline the actions countries intend to take beginning in 2020 under a proposed global climate agreement. These plan will play a big part in moving us forward on the path toward a low-carbon, clean energy future.
INDC or Intended Nationally Determined Contribution.
First set up in 1988 under two UN organizations, the IPCC surveys the research on climate change happening all around the world and reports to the public about the current state of our scientific knowledge.
IPCC or the Intergovernmental Panel on Climate Change.
the main component of natural gas, a common fossil fuel source and a greenhouse gas that traps heat in the atmosphere. It doesn’t stay in the atmosphere as long as carbon dioxide, but it absorbs 84 times more heat, making it very harmful to the climate.
Methane
actions that reduce emissions or enhance the sinks of greenhouse gases or topping climate change from getting worse. Examples are
planting trees for CO2 sequestration. It can also include developing and deploying new technologies, using renewable energies like wind and solar, or making older equipment more energy efficient and waste management approaches.
Mitigation (of climate change):
energy that comes from naturally replenished resources, such as sunlight, wind, waves, and geothermal heat.
Renewable energy
it relates to climate change is caused by two major factors. First, more water is released into the ocean as glaciers and land ice melts. Second, the ocean expands as ocean temperatures increase. Both of these consequences of climate
change are accelerating sea-level rise around the world, putting millions of people who live in coastal communities at risk.
Sea-Level Rise
a development that meets the needs of the present without compromising the ability of future generations to meet their own needs and balances social, economic and environmental concerns.
Sustainable development
a level of change in system properties beyond which a system reorganizes, often abruptly, and does not return to the initial state even if the drivers of the change are abated. It is a critical threshold when global or regional climate changes from one stable state to another stable state. It happened when it is too late to stop the effects of climate change.
Tipping point
an environmental treaty that nations joined in 1992, with the goal of stabilizing greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous human interference with the climate system.
UNFCCC or the United Nations Framework Convention on Climate Change
atmospheric conditions in the short term, including changes in temperature, humidity, precipitation, cloudiness, brightness, wind, and visibility.

sea level rise,
