When did greenpeace try to stop global warming?

Greenpeace has actively campaigned against global warming since its founding in 1971, but its significant efforts intensified in the late 1980s and 1990s. The organization has focused on raising awareness about climate change, advocating for renewable energy, and pushing for policy changes to reduce greenhouse gas emissions. Key campaigns include promoting the use of sustainable energy sources and opposing fossil fuel projects. Over the years, Greenpeace has participated in various international climate negotiations to urge governments to take stronger action against climate change.
