Frequently Asked Questions (FAQs)

What is the difference between climate change mitigation and adaptation?

Climate change mitigation refers to actions taken to reduce greenhouse gas emissions and slow down the rate of climate change. Examples include transitioning to renewable energy and improving energy efficiency. Climate change adaptation involves adjusting to the actual and expected effects of climate change. Examples include building seawalls to protect against rising sea levels and developing drought-resistant crops. Both mitigation and adaptation are necessary to address the climate crisis.

How much does it cost to stop climate change?

The cost of stopping climate change is substantial, estimated to be trillions of dollars annually. However, the cost of inaction is far greater, considering the economic and social impacts of extreme weather events, sea-level rise, and other climate-related disasters. The cost-effectiveness of different mitigation strategies varies, with some, like renewable energy deployment, becoming increasingly competitive.

Is it too late to stop climate change?

While the window of opportunity is narrowing, it is not too late to stop climate change. However, drastic and immediate action is required to limit warming to 1.5°C or even 2°C above pre-industrial levels, the goals set by the Paris Agreement. Delaying action will make the challenge more difficult and costly.

What are the biggest sources of greenhouse gas emissions?

The biggest sources of greenhouse gas emissions are:

1. Energy production (electricity and heat): Primarily from burning fossil fuels (coal, oil, and natural gas).
2. Industry: Manufacturing processes, including cement, steel, and chemicals production.
3. Transportation: Cars, trucks, airplanes, and ships.
4. Agriculture, forestry, and land use: Deforestation, livestock farming, and fertilizer use.

What are the most effective ways to reduce my carbon footprint?

The most effective ways to reduce your carbon footprint include:

1. Reducing meat consumption: Especially beef and lamb, which have high carbon footprints.
2. Switching to renewable energy: Purchasing electricity from renewable sources or installing solar panels.
3. Using public transportation, biking, or walking: Reducing reliance on private vehicles.
4. Improving home energy efficiency: Insulating your home and using energy-efficient appliances.
5. Reducing waste: Recycling, composting, and avoiding single-use plastics.

How does deforestation contribute to climate change?

Deforestation contributes to climate change in two main ways:

1. Releasing stored carbon: Trees absorb carbon dioxide from the atmosphere and store it in their biomass. When forests are cleared, this stored carbon is released back into the atmosphere as carbon dioxide.
2. Reducing carbon sequestration: Forests play a crucial role in absorbing carbon dioxide from the atmosphere. Deforestation reduces the Earth’s capacity to remove carbon dioxide.

What is the role of technology in addressing climate change?

Technology plays a critical role in addressing climate change. Key technological solutions include:
