Frequently Asked Questions (FAQs)

Q1: What is the difference between climate change mitigation and adaptation?

Mitigation refers to efforts to reduce or prevent greenhouse gas emissions, such as transitioning to renewable energy and improving energy efficiency. Adaptation involves adjusting to the effects of climate change, such as building seawalls to protect against rising sea levels or developing drought-resistant crops. Both are essential responses to climate change.

Q2: Why is it important to limit global warming to 1.5 degrees Celsius?

Limiting warming to 1.5 degrees Celsius, as outlined in the Paris Agreement, would significantly reduce the risk of severe and irreversible climate impacts, such as extreme weather events, sea level rise, and ecosystem collapse. Exceeding this threshold would push us closer to dangerous tipping points, leading to potentially catastrophic consequences.

Q3: What role can individuals play in mitigating climate change?

Individuals can make a significant difference by adopting sustainable practices, such as reducing their energy consumption, using public transportation, eating less meat, and supporting policies that promote climate action. Collective action by individuals can drive systemic change.

Q4: Is it possible to achieve net-zero emissions by 2050?

Achieving net-zero emissions by 2050 is a challenging but necessary goal. It requires rapid and widespread adoption of clean energy technologies, significant investments in carbon dioxide removal, and strong policy support. While ambitious, it is technically and economically feasible with sufficient political will.
