What is Climate Change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily driven by human activities such as burning fossil fuels, deforestation, and industrial processes.

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

What is a carbon sink?

Back

A carbon sink is any natural or artificial reservoir that absorbs more carbon dioxide from the atmosphere than it releases, such as forests, oceans, and soil.

Front

How do cyanobacteria influence climate?

Back

Cyanobacteria, through photosynthesis, absorb carbon dioxide and release oxygen, which historically contributed to global cooling during the Precambrian period.

Front

What is geoengineering?

Back

Geoengineering refers to large-scale interventions in the Earth's natural systems to counteract climate change, such as injecting aerosols into the atmosphere to reflect sunlight.

Front

What is carbon trading?

Back

Carbon trading is a market-based approach to controlling pollution by providing economic incentives for reducing the emissions of pollutants, particularly carbon dioxide.

Front

What is the role of trees in climate change mitigation?

Back

Trees act as carbon sinks by absorbing carbon dioxide during photosynthesis, thus helping to reduce the overall concentration of greenhouse gases in the atmosphere.

Front

What is the impact of deforestation on climate change?

Back

Deforestation increases carbon dioxide levels in the atmosphere by reducing the number of trees that can absorb CO2, contributing to global warming.

Front

What are the effects of global warming?

Back

Global warming leads to rising sea levels, more extreme weather events, loss of biodiversity, and changes in agricultural productivity.
