What are the impacts of global warming?
Impacts include altered ecosystems, food and water shortages, increased wildfires, stronger storms, loss of biodiversity, and health risks to humans.
What role do oceans play in global warming?
Oceans absorb about 90% of the excess heat from global warming, which can lead to changes in ocean currents, acidification, and loss of marine life.
How does deforestation contribute to global warming?
Deforestation reduces the number of trees that can absorb CO2, a key greenhouse gas, and also releases CO2 stored in trees when they are cut down or burned.
What are carbon offsets?
Carbon offsets are reductions in emissions of CO2 or other greenhouse gases made to compensate for emissions made elsewhere, such as investments in renewable energy projects.
How do feedback loops amplify the effects of global warming?
Feedback loops amplify effects through processes like the albedo effect, where melting ice exposes darker surfaces that absorb more heat, and the release of methane from thawing permafrost.
What is the Paris Agreement?
The Paris Agreement is an international treaty adopted in 2015 that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels.
What is the Kyoto Protocol?
The Kyoto Protocol is an international treaty that commits its parties to reduce greenhouse gas emissions, based on the recognition that global warming is occurring.
How do humans contribute to global warming?
Humans contribute to global warming through activities like burning fossil fuels, deforestation, and industrial processes, which increase the concentration of greenhouse gases in the atmosphere.
What is the evidence for global warming?
Evidence includes rising global temperatures, shrinking ice sheets, declining Arctic sea ice, glacial retreat, sea level rise, and increased frequency of extreme weather events.
How does agriculture contribute to global warming?
Agriculture contributes through methane emissions from livestock, deforestation for cropland, and the use of nitrogen-based fertilizers that release nitrous oxide.
What is carbon footprint?
A carbon footprint is the total amount of greenhouse gases emitted directly or indirectly by an individual, organization, event, or product.
What is the role of renewable energy in reducing global warming?
Renewable energy sources, like wind, solar, and hydro, emit little to no greenhouse gases and can replace the burning of fossil fuels, thus reducing our carbon footprint.
How does urbanization contribute to global warming?
Urbanization often leads to increased energy use, heat generation, and the replacement of natural surfaces with materials that retain heat, all of which can contribute to global warming.
What are the consequences of melting polar ice caps?
Melting polar ice caps contribute to sea level rise, which can lead to coastal erosion, flooding, and the displacement of human communities and wildlife.
What is global warming?
Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, predominantly the emission of greenhouse gases.
What are some health effects of global warming?
Health effects of global warming include heatstroke, respiratory problems, spread of vector-borne diseases, and mental health issues.
What is the relationship between energy use and global warming?
The more energy we use, especially from fossil fuels, the more CO2 we emit, contributing to the greenhouse effect and global warming.
How does transportation contribute to global warming?
Transportation contributes to global warming through the burning of fossil fuels for vehicles which emits CO2 and other greenhouse gases.
How do changes in land use contribute to global warming?
Land use changes like deforestation, urban sprawl, and agriculture expansion release stored carbon and reduce carbon sequestration, increasing greenhouse gas emissions.
How does global warming affect sea levels?
Global warming leads to sea level rise through the melting of ice over land and the thermal expansion of seawater as it warms.
Why is global warming a concern for biodiversity?
Global warming alters habitats and ecosystems, placing stress on species that may not be able to adapt quickly enough, potentially leading to extinction.
What is climate sensitivity?
Climate sensitivity is the measure of how much the Earth's temperature will eventually rise due to a doubling of the concentration of CO2 in the atmosphere.
What is the greenhouse effect?
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere.
How can planting trees reduce global warming?
Trees absorb CO2 from the atmosphere during photosynthesis, thereby reducing the concentration of this greenhouse gas and mitigating global warming.
What are greenhouse gases?
Greenhouse gases, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap heat in the Earth's atmosphere, contributing to global warming.
