Donald Trump, who previously withdrew the United States from the Paris Agreement and regards climate change as a 'scam', threatens to repeat his actions if he returns to the White House.
Trump's potential reinstatement of the oil and gas sector poses a risk to greenhouse gas regulation and hence, global warming.
The failure of COP29 could discredit future conferences, further aggravating the climate crisis.
Progress in Brazil under Lula, who has achieved a 30.6% reduction in Amazon deforestation, presents a model of climate action.
China, another major emitter, has recognized the economic and environmental importance of addressing climate change.
Conclusion: The ability to address the climate crisis is not a matter of possibility, but of will. Trump could obstruct this progress, but examples like Brazil and China demonstrate that effective action is both possible and necessary.
