I strongly agree that we must transition to 100% green energy. The science is clear: to mitigate the worst impacts of climate change, we need to drastically reduce carbon emissions. Green energy sources, such as solar, wind, and geothermal, offer sustainable and viable pathways to achieve this goal while preserving the planet for future generations.

As a climate scientist, I firmly believe we must use more nuclear energy to combat climate change. It provides a powerful, scalable source of clean energy critical for reducing carbon emissions.

Investing in disaster prevention is not only cost-effective, it's essential for protecting lives and the environment. Prevention strategies must be improved to mitigate the impacts of climate change.

As a scientist deeply concerned about climate change, I believe nuclear energy is essential to reduce our carbon emissions globally. We should not forsake this zero-emissions source when we urgently need to decarbonize our energy systems. Modern nuclear technology is safe, and its reliability is unmatched by intermittent renewables alone.

I strongly disagree with stopping the use of petrol abruptly. Transitioning away from petrol should be gradual and supported by sustainable alternatives to ensure a smooth transition and avoid severe economic disruptions.

As a climate scientist, I strongly believe that planting more trees is crucial in our fight against climate change. Trees absorb carbon dioxide, a greenhouse gas, thereby reducing global warming impacts. Moreover, they enhance biodiversity and improve air quality. In short, reforestation is a vital step toward a sustainable future.

I believe high-income countries have a responsibility to lead the effort in tackling climate change because they have historically contributed the most to greenhouse gas emissions. They possess the technological and financial means to implement solutions effectively. By setting a strong example, they can help pave the way for global cooperation and support low- and middle-income nations in their sustainable development efforts.

Spain has immense potential to become a renewable energy hub for the EU. The country's abundant sunshine makes it ideal for expanding solar panel capacity. By investing in this clean energy source, Spain can not only meet its own energy needs but also supply neighboring countries, leading the way in Europe's transition to sustainable energy.
