Climate change

What is weather?

Weather refers to the short-term conditions of the atmosphere at a specific place and time, including temperature, humidity, precipitation, wind speed, and atmospheric pressure.

What is climate?

Climate describes the long-term average of weather patterns over a significant period (typically 30 years or more) in a particular region.

What characterizes a Tropical climate?

Warm year-round with high rainfall.

What characterizes a Dry climate?

Low precipitation; includes deserts and semi-arid regions.

What are the characteristics of a Temperate climate?

Moderate temperatures with distinct seasons.

What defines a Continental climate?

Large seasonal temperature variations; cold winters and warm summers.

What characterizes a Polar climate?

Extremely cold year-round.

What is conduction in heat transfer?

Direct transfer of heat between molecules in contact.

What is convection in heat transfer?

Movement of heat by fluid motion, where warmer, less dense fluids rise and cooler, denser fluids sink.

What is radiation in heat transfer?

Transfer of energy via electromagnetic waves.

What are the stages of the water cycle?

Evaporation, condensation, precipitation, runoff/infiltration, and transpiration.

What effect do volcanic eruptions have on climate?

They release aerosols and gases that can temporarily cool the planet by reflecting sunlight.

What is the anthropogenic greenhouse effect?

The increase in greenhouse gas concentrations due to human activities.

What are natural sources of greenhouse gases?

Volcanic eruptions, respiration, decomposition, and ocean-atmosphere exchange.

What are anthropogenic sources of greenhouse gases?

Fossil fuel combustion, deforestation, industrial emissions, and agriculture.

How do carbon dioxide (CO₂) levels affect global temperature?

CO₂ is a long-lived gas that primarily contributes to anthropogenic warming.

What is the effect of methane (CH₄) on climate?

Methane is more potent than CO₂ but shorter-lived; it's significant from agriculture and fossil fuels.

What are the effects of global climate change?

Rising temperatures, melting glaciers, sea-level rise, extreme weather events, and biodiversity loss.

What indicators signify global climate change?

Rising global temperatures, melting ice sheets, rising sea levels, ocean acidification, and shifts in species distribution.

What effects are observed in the Arctic due to climate change?

Melting ice caps and loss of habitat for polar species.

How do coastal areas respond to climate change?

They experience flooding due to rising sea levels.

What challenges do agricultural zones face from climate change?

Reduced crop yields due to changing precipitation patterns.

What is a critical approach to understanding media perspectives on climate change?

Critical analysis is essential to distinguish credible information from biased or inaccurate sources.
