temperaturenounA measure of how hot or cold something is, typically expressed in degrees.The temperature dropped sharply as soon as the sun went down.
greenhouse gasnounA gas, such as carbon dioxide or methane, that traps heat in Earth's atmosphere and contributes to warming.Burning fossil fuels releases large amounts of greenhouse gas into the atmosphere.
emissionnounSomething released or discharged into the air, especially gas, radiation, or light.The factory reduced its carbon emission after installing new filtering equipment.
carbon footprintnounThe total amount of greenhouse gases produced by a person's or organization's activities.Flying less is one simple way to reduce your carbon footprint.
fossil fuelnounA natural fuel such as coal, oil, or gas formed from the remains of ancient organisms.Many countries are trying to reduce their reliance on fossil fuels for electricity.
renewableadjectiveAble to be replaced naturally or continue indefinitely, or capable of being extended or renewed.Solar and wind are renewable sources of energy that will not run out.
sustainabilitynounThe capacity to maintain a process, resource, or system over time without depleting it or causing lasting damage.The company published a report detailing its progress toward greater sustainability in packaging and shipping.
droughtnounA long period of unusually low rainfall that leads to a shortage of water.The drought forced farmers to ration water carefully across their fields.
precipitationnounWater that falls from clouds as rain, snow, hail, or another liquid or frozen form.Most of the winter precipitation here falls as snow.
humiditynounThe amount of water vapor present in the air.The humidity made the summer afternoon feel hotter than the thermometer showed.
ecosystemnounThe living things in an area together with their nonliving surroundings and the ways they interact.The pond ecosystem includes insects, plants, water, and sediment.
biodiversitynounThe variety of plant and animal life found in a particular habitat or the world.Rainforests contain an extraordinary level of biodiversity compared to most other ecosystems.
deforestationnounThe large-scale clearing of forests, typically for farming, logging, or development.Deforestation in the region has led to significant loss of wildlife habitat.
pollutionnounThe presence of harmful or unwanted substances in the environment, causing damage to air, water, land, or living things.Air pollution in the city worsens noticeably during the hot summer months.
ozonenounA form of oxygen with three atoms per molecule that forms a protective layer in the upper atmosphere.Scientists monitor the hole in the ozone layer above Antarctica every year.
glaciernounA large, slow-moving mass of ice formed from compacted snow over long periods on land.The glacier has retreated noticeably up the valley over the past fifty years.
sea levelnounThe average height of the ocean's surface, used as a standard reference point for measuring land elevation.The city sits barely two meters above sea level, so it floods easily during storms.
erosionnounThe gradual wearing away of soil, rock, or land by natural forces such as wind, water, or ice.Years of coastal erosion have caused the cliff to shrink noticeably.
adaptationnounThe process of changing to become better suited to new conditions, or a modified version of an original work.The lizard's coloring is an adaptation that helps it hide from predators.
mitigationnounThe action of reducing the severity, seriousness, or harmful effects of something.The city invested in flood mitigation projects along the riverbank.
resiliencenounThe ability to recover quickly from difficulties, setbacks, or hardship.Her resilience after the accident inspired everyone who watched her recovery.
carbon dioxidenounA colorless gas produced by breathing, burning fuel, and decay, and absorbed by plants.Trees absorb carbon dioxide from the air and release oxygen in return.
methanenounA colorless, odorless, flammable gas made of carbon and hydrogen that is the main component of natural gas.Cows release methane as part of their digestion, which contributes to greenhouse gas emissions.
warmingnounThe process of becoming warmer, especially the gradual rise in the earth's average temperature.Scientists have linked global warming to rising sea levels and melting glaciers.
ice capnounA thick, permanent layer of ice and snow covering a large area of land, especially near the poles.The Greenland ice cap holds enough frozen water to raise sea levels significantly if it melted.
permafrostnounA layer of soil beneath the earth's surface that stays frozen throughout the year.Scientists worry that thawing permafrost in the Arctic could release trapped greenhouse gases.
conservationnounThe careful protection and management of natural resources, wildlife, or historic sites to prevent loss or damage.The organization funds conservation projects to protect endangered rainforest habitats.

Global warming vocabulary explained

Global warming vocabulary centers on how greenhouse gases like carbon dioxide and methane trap heat in the atmosphere, raising average temperatures over time. Words like emission and fossil-fuel describe the causes, while sea-level, glacier, and drought describe visible effects. Mitigation and adaptation describe two different kinds of response, one aimed at slowing the warming and the other at coping with changes already happening.

Frequently asked questions

What is the difference between climate vocabulary and weather vocabulary?

Weather words describe short-term conditions like a single storm or hot day, while climate words describe long-term patterns measured over many years.
