Frequently Asked Questions (FAQs)

1. Is climate change really happening, and what’s the evidence?

Yes, climate change is unequivocally happening. The overwhelming scientific consensus, supported by decades of data, confirms the Earth is warming at an unprecedented rate. The evidence includes rising global temperatures, melting glaciers and ice sheets, rising sea levels, changes in precipitation patterns, and increased frequency of extreme weather events. These changes are directly linked to the increase in greenhouse gas concentrations in the atmosphere, primarily due to human activities.

2. What are the main greenhouse gases, and why are they important?

The main greenhouse gases are carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gases (F-gases). These gases trap heat in the atmosphere, leading to a warming effect. CO2, primarily from burning fossil fuels, is the most abundant and long-lasting. Methane, although shorter-lived, has a much higher warming potential. Nitrous oxide comes from agricultural and industrial activities. F-gases, used in various industrial applications, are extremely potent greenhouse gases. They are important because their increased concentrations contribute to the greenhouse effect, disrupting the Earth’s climate system.

3. How does deforestation contribute to climate change, and what can be done about it?

Deforestation contributes to climate change in two primary ways. First, trees absorb carbon dioxide from the atmosphere during photosynthesis and store it in their biomass. When forests are cleared, this stored carbon is released back into the atmosphere as CO2. Second, deforestation reduces the Earth’s capacity to absorb carbon dioxide, exacerbating the greenhouse effect. To combat this, we must reduce deforestation rates by enforcing regulations, promoting sustainable forestry practices, and supporting reforestation and afforestation efforts. Additionally, addressing the underlying drivers of deforestation, such as unsustainable agriculture and illegal logging, is crucial.

4. What is carbon capture and storage (CCS), and how can it help mitigate climate change?

Carbon capture and storage (CCS) is a technology that captures carbon dioxide emissions from industrial sources, such as power plants and factories, and stores it underground, preventing it from entering the atmosphere. CCS can significantly reduce emissions from these sources, contributing to climate change mitigation. However, CCS technology is still under development and faces challenges related to cost, energy consumption, and long-term storage security. Widespread deployment of CCS requires further research, development, and government support.

5. What are the potential economic impacts of climate change, and how can we adapt to them?

The potential economic impacts of climate change are substantial and far-reaching. These include damage from extreme weather events, such as hurricanes and floods, disruptions to agriculture and food production, increased healthcare costs, and reduced productivity.
