Quiz: Test Your Knowledge on How Hot is the Planet: A 5.23 Global Temperature Challenge

Carbon dioxide (CO2) is the primary greenhouse gas released into the atmosphere due to human activities such as burning fossil fuels. It traps heat in the atmosphere, leading to the greenhouse effect and global warming.

Global warming is the gradual increase in Earth's average surface temperature over time. It is primarily caused by human activities that release greenhouse gases into the atmosphere, leading to the enhanced greenhouse effect.

The burning of fossil fuels in vehicles, airplanes, and ships is a significant source of carbon dioxide emissions. These emissions contribute to the accumulation of greenhouse gases in the atmosphere and global warming.

Wind power is a renewable energy source that generates electricity without emitting greenhouse gases. It can help reduce the reliance on fossil fuels and mitigate the impacts of global temperature rise.

The Paris Agreement is an international treaty signed by countries to collectively combat climate change and limit global temperature rise. The goal is to keep the increase in global average temperature well below 2 degrees Celsius above pre-industrial levels.

The Arctic region is warming at a faster rate than the global average due to a phenomenon known as Arctic amplification. The melting of ice and snow contributes to the warming feedback loop in this area.

Continued global temperature rise leads to the melting of glaciers and ice sheets, causing thermal expansion of seawater. This results in rising sea levels, which can have significant impacts on coastal communities.

The global community aims to limit global temperature rise to 1°C above pre-industrial levels to avoid the most severe impacts of climate change, such as sea-level rise, extreme weather events, and ecosystem disruptions.

Volcanic eruptions can inject large amounts of ash and aerosols into the atmosphere, which can temporarily block sunlight and lead to a cooling effect known as "volcanic winter."

Anthropogenic warming refers to the increase in Earth's average temperature caused by human activities, particularly the emission of greenhouse gases like carbon dioxide from industrial processes, transportation, and deforestation.
