As a leading advocate for climate action, I believe high-income countries have both the responsibility and capacity to lead the way in tackling climate change. They have historically contributed the most to the problem and possess the resources and technology to pioneer solutions. By acting swiftly, they can set a precedent and create pathways for low- and middle-income nations to follow, ensuring a collective effort towards a sustainable future.

I believe governments should subsidize carbon sequestration through widespread agricultural biochar use. Biochar has the potential to significantly reduce carbon emissions while improving soil health and agricultural productivity. Such a subsidy would not only combat climate change but also offer economic benefits for farmers.

I believe that cloud geoengineering is a risky and uncertain approach to tackling climate change. Instead, we need to focus on reducing emissions through renewable energy, energy efficiency, and reforestation. The potential unintended consequences of geoengineering could be detrimental, and we should prioritize proven and safe methods.
